Beware these 5 signs of a ‘highly invasive' brain cancer — patients typically survive only 15 months
A 57-year-old UK father of four recently made headlines when he revealed the bizarre clue that preceded his Stage 4 glioblastoma diagnosis — a 'strange sweet caramel smell.'
'We didn't think much of it,' said Costa Fantis's 27-year-old son, Antonio. 'We definitely didn't know it was a symptom of something so serious.'
Before two-time Grammy winner Michael Bolton, 72, was diagnosed with glioblastoma in 2023, he experienced confusion, balance issues, nausea and severe headaches.

The tumor, which occurs when supportive cells in the brain grow and divide uncontrollably, is extremely aggressive and deadly. Most patients survive only 14 to 16 months after diagnosis.
'What makes glioblastoma particularly difficult to treat is its highly invasive nature — it spreads microscopic cancer cells deep into surrounding brain tissue, making it impossible to remove completely with surgery,' Dr. Joseph Georges, a neurosurgeon based in Phoenix, told The Post.
Georges shares five early glioblastoma warning signs — and how a specialized cell therapy may prolong patient lives.
What are the risk factors for glioblastoma?
About 14,500 new glioblastoma cases are diagnosed annually in the US.
5 Dr. Joseph Georges, a neurosurgeon based in Phoenix, reveals five early glioblastoma warning signs — and how a specialized cell therapy may prolong patient lives.
The average age of diagnosis is around 64 — the cancer tends to affect adults 45 to 70 years old.
Exposure to ionizing radiation as part of radiation therapy for other cancers and certain genetic disorders, such as Turcot syndrome and Lynch syndrome, can increase glioblastoma risk.
However, most cases 'occur spontaneously in individuals without risk factors,' said Georges, an assistant professor of neurosurgery at the University of Arizona College of Medicine and Banner University Medical Center-Phoenix.
What are the symptoms?
Symptoms depend on the tumor's location within the skull.
They may include headaches, confusion, seizures, speech difficulty or weakness on one side of the body, Georges said.
In Bolton's case, his daughters noticed unusual behavior during a family bowling night in the fall of 2023.

He had bowled out of turn and fallen out of his chair. He was diagnosed a few weeks later.
Fantis's tumor appears to have developed in the temporal lobe, which plays a crucial role in processing smells.
How is it diagnosed?
The tumor can be identified with a CT scan or MRI, and the diagnosis confirmed with a tissue biopsy.
'Several factors influence how long a person might live with glioblastoma,' Georges said, 'including their overall health, neurological function at diagnosis, age and how well they respond to treatments such as surgery, radiation and chemotherapy.'
The molecular characteristics of the tumor — like whether it has mutations — can affect the prognosis.
How is glioblastoma treated?
Metastatic brain tumors — tumors that start elsewhere in the body and spread to the brain — tend to form masses that are better defined than glioblastomas and that can be surgically removed more easily.
'Glioblastoma's diffuse growth pattern, genetic complexity and resistance to standard treatments make it one of the most challenging brain tumors to treat,' Georges noted.
'Complete removal is usually not achievable due to the tumor's infiltrative nature.'

Surgery is often followed by radiation therapy to eliminate residual tumor cells and delay progression and chemotherapy to enhance the effectiveness of radiation.
Despite this multi-pronged strategy, Georges admitted that 'glioblastoma generally has a poor prognosis due to its aggressive biology and treatment resistance.'
How can DOC1021 help?
Georges said he has seen better outcomes with an individualized approach.
He was the principal investigator of a Phase 1 clinical trial evaluating Dubodencel, also known as DOC1021, which harnesses the power of the patient's special immune cells, called dendritic cells.
The cells are exposed to the unique antigens of the tumor outside the body.
'Once trained, the cells are multiplied and then returned to the patient, where they help the immune system launch a targeted attack against the cancer,' Georges said.
'Because this approach uses the patient's own immune cells and doesn't require genetic modification, it offers a highly personalized and comprehensive way to address the complexity and variability of glioblastoma.'
5 These before-and-after brain scans show glioblastoma resolution with DOC1021.
The Food and Drug Administration granted fast-track designation to DOC1021, developed by Diakonos Oncology, to treat glioblastoma and pancreatic cancer.
Some patients in the DOC1021 Phase 1 trial are approaching 24 to 36 months of survival.
'Early clinical results from the trial showed a 12-month overall survival rate of 88%, markedly higher than the approximately 60% typically seen with standard of care,' Georges said.
New Jersey resident Pamela Goldberger, 65, underwent brain surgery, six weeks of chemotherapy and radiation, six weeks of the cell therapy and a year of chemo maintenance as part of the DOC1021 Phase 1 trial. Now, she is back to playing tennis several times a week 2½ years after her diagnosis.
'I'm living my best life right now, and I'm not restricted by not being able to do anything that I would want to do,' she recently told Fox News Digital.
The Phase 2 clinical trial is underway — it's expected to be available at 20 US sites.

How sleeping with your earrings in can age you prematurely: dermatologist warning
Talk about a lobe low. According to a dermatologist, keeping your studs in while you sleep isn't doing your future self any favors. 'I'm gonna give you some advice so that when you're sitting around with your girlfriends 20 years from now and they're all complaining of this cosmetic issue, you're gonna be like, well, I saw this random doctor on social media talk about this 20 years ago,' shared Dr. Samantha Ellis. The cosmetic issue in question? Saggy earlobes. 'As we age, our earlobes get saggier, they get looser, and if you wear earrings, that can become a problem because your earrings can start to look very sad in your ear holes,' she explained. Ellis noted that the issue typically doesn't express itself until we reach 40 plus, a point at which 'your earrings are not looking as cute in their holes as they once were.' The good news? You can keep your lobes pert with one quick trick. 'The easiest thing you can do to prevent premature stretching of your ear holes is to not sleep in your earrings,' she said. This does not apply to piercings in the upper ear, where the cartilage is fortified — if sleeping with earrings in those areas doesn't bother you, there's no harm or aesthetic pitfalls in doing so, she said. 'What I'm talking about is wearing earrings in this loose, floppy earlobe night after night, year after year, putting unnecessary strain and stress on your piercing holes and causing them to stretch out way sooner than they actually should,' she explained while pulling on her own earring-less lobe. 4 The combined effects of gravity and sleeping in your statement earrings can lead to yawning, piercing holes, and a loose fit for your favorite studs. sameer – Indeed, the combined effects of gravity and sleeping in your statement earrings can lead to yawning piercing holes, and a loose fit for your favorite studs. For those whose lobes have already been compromised from years of overuse, help is available in the form of ear fillers. The extra volume from fillers gives earring posts more cushion, which helps studs stick out straight and allows diamonds to catch the light. Unlike facial filler procedures, ear injections rarely go awry. There's a small risk of hitting a blood vessel, which could prevent healthy cell turnover, 'but you're not going to lose your hearing,' Dr. Melissa Doft, an uptown plastic surgeon, previously told The Post. There's also no downtime post-treatment. 'You can come in, have it done, and go to a luncheon afterward, or do a pilates class afterward.' Other experts maintain that, in addition to stretching out from wearing/sleeping in accessories, ear lobes naturally enlarge as we age. 'In general, as people get older, their ears get bigger,' New York-based plastic surgeon Dr. Stafford Broumand previously told Page Six. 4 Kris Jenner (pictured in 2016) underwent earlobe reduction surgery in 2018. Getty Images 4 Jenner (pictured in 2022) got the procedure in an episode of 'Keeping Up With the Kardashians.' Getty Images for Baby2Baby 'You think that they stop growing at a certain age, but they slowly get bigger. The earlobe tends to elongate so that gives an aging appearance. 'You want to sort of have a perky, full, small, tight ear, and as people age, they want to sort of minimize the subtleties of aging, and one of those is the ear size.' While critics call the treatment an easy way to prey on the insecurities of the aging population, Doft says having floppy earlobes can be surprisingly upsetting. In many cases, she said, her clients most miss wearing the earrings they'd received as mementos of significant life events or gifts. Lobe improvement for the love of bling is exactly what Brielle Biermann claimed her mother, Real Housewives of Atlanta star Kim Zolciak, did, tweeting in 2018: 'My mom gets filler in her ears because her diamond earrings are too heavy… #richpeopleproblems.' Kardashian matriarch Kris Jenner took the desire for perky ears a step — and a scalpel — further, surgically reducing her earlobes in 2018.

‘Superagers' seem to share this one key personality trait
The brains of superagers are different from the rest of us. Here's what 25 years of research reveals about why some people remain sharp well into their 80s and 90s. There's no one lifestyle linked to staying impressively sharp as you age—but a new study suggests there is at least one personality trait: gregariousness. Brain scans and post-mortem examinations of superagers reveal several differences that may explain their outgoing behavior. Photograph by Britt Erlanson, Getty Images What if you could stay sharp in old age? We may be closer to understanding how some people over 80 became what's known as 'superagers'—meaning they have the cognitive function of someone decades younger. In a new paper published in the journal Alzheimer's & Dementia, researchers at Northwestern University reveal what they've learned in the last 25 years of studying more than a hundred superagers—and analyzing some 77 post-mortem superager brains. The new paper shows that the brains of superagers share a host of characteristics that may allow them to retain their cognitive function. And while there's still much to understand about whether lifestyle choices play a role, researchers did observe one personality trait that all superagers seem to share: they're sociable. (Can aging be cured? Scientists are giving it a try.) The findings further contributed to developing a 'distinct neurobiological signature' for identifying superagers: You might be one if you're 80 or older and can recall at least nine words about 30 minutes after someone reads you a 15-word list. Eventually, this research could build the foundation for future neurodegenerative disease interventions. 'One creative and novel way to understand or prevent Alzheimer's disease is to study those that don't get it,' says Tamar Gefen, a study author and assistant professor of psychiatry and behavioral sciences at Northwestern University. That's why superagers are so fascinating, she says. 'Their memories are just outstanding even compared to their peers.' Superagers are outgoing—and tenacious You might not be able to control the characteristics of your brain. But the Northwestern researchers have studied whether there are any lifestyle or personality traits that superagers share, and just one trait stood out—gregariousness. 'These are people living life on their own terms,' Gefen says. Whether that means volunteering in communities, or having 'multiple romantic partners,' as some study participants did, it's clear superagers are connected by their values of autonomy and connection, adds Gefen. Her team found potential biological underpinnings for these differences. The study shows superagers have more of a certain type of neurons associated with sociability compared to their peers—and surprisingly, more of these neurons than people much younger. Known as von Economo neurons, they are found in the anterior cingulate gyrus of the brain, which plays a role in emotion and cognitive processing. (7 simple science-backed rules for living longer.) 'You really only find these in species that are social, like whales,' says Joel Kramer, a professor of neuropsychology at the University of California, San Francisco. His team is currently studying frontotemporal dementia patients, and so far found a 'striking loss' of von Economo neurons in those who are less empathetic. Indeed, the study notes these neurons have been found in emotional and social animals like great apes, elephants, and cetaceans like whales or dolphins. Animals 'that have strong connections tend to outlive and outsmart their peers. It's like the pack culture,' Gefen says. Having a thicker anterior cingulate gyrus also suggests superagers are more tenacious. This is a region that is 'traditionally not associated with memory, but motivation,' says Alexandra Touroutoglou, an assistant professor of neurology who also studies superagers at Harvard University. 'This may reflect that superagers may be more willing to exert effort in the face of challenges.' Northwestern researchers Sandra Weintraub and Marsel Mesulam founded the SuperAging Research Program more than 25 years ago after they examined a post-mortem brain of an 81-year-old woman with the cognitive function of someone in her 50s that they had received from the University of Miami's Miami Brain Endowment Bank. This finding challenged the prevalent idea that severe cognitive decline is unavoidable with age. Fast forward decades later, and Northwestern has built up a brain bank of its own with 77 post-mortem brains, says Gefen, which she finds particularly exciting, as autopsy is considered the gold standard for identifying the causes and progression of disease. (When does old age begin? Science says later than you might think.) One key finding from the study is that cortical thinning, or brain shrinkage, in superagers is much slower than their peers—which may explain why they're less prone to neurodegeneration associated with conditions from dementia to Parkinson's disease. Over an 18-month period, superager cortical thickness was reduced by 1.06 percent, while peers' reduced by 2.24 percent. The researchers speculate in the paper that superagers could have been born with bigger brains; however, that 'is unlikely to be the entire answer given the absence of obvious differences in skull morphology.' Additionally, superagers had a more robust cholinergic system, a neurotransmitter system associated with memory, learning, and motor function. Cholinergic neurons in the basal forebrain are thought to be among the first to show degeneration as you age. They communicate with each other via the neurotransmitter acetylcholine, which is important for alertness, explains Kramer. For example, Kramer says the reason why you might feel 'a little dopey and not so sharp' when you take anti-seasickness medication is because it reduces acetylcholine. On the other hand, modern dementia therapeutics like donepezil slow the breakdown of acetylcholine by inhibiting an enzyme, acetylcholinesterase, thus making you less forgetful. The Northwestern study found that among participants' acetylcholinesterase-rich neurons, superagers had less of the enzyme than their peers. This may suggest acetylcholine degrades slower among superagers, and possibly make them more resistant to worsening memory. Superager brains may also be more resistant to the changes in the brain linked to Alzheimer's. An autopsy of a 92-year-old superager in the Northwestern study showed prominent neurofibrillary tangles, a hallmark of the disease. But the superager also had a 'much greater' amount of viable, healthy neurons, which could play a 'decisive role' in memory. 'This is an important finding, because it underscores that superagers may not avoid all pathological age-related brain changes,' Touroutoglou says. 'It also shows the viable neurons may play an important role that has not been studied.' Does lifestyle make a difference? Surprisingly, the study found little difference between the cognitive performance of superagers who lived healthy lifestyles—i.e. ate well and exercised—and those who did the opposite. Still, this should be interpreted with caution, experts say. Because this isn't a controlled longitudinal study that started when people were young, 'you cannot completely know whether these sorts of behaviors are helping or not,' Gefen says. Further, other research suggests that lifestyle does indeed play a role. In 2024, for example, a commission from The Lancet estimated that up to 45 percent of dementia cases may be preventable if people adopt regular exercise or abstain from excess intoxication. 'I think it's absolutely true lifestyle matters. There's too much evidence,' Kramer says. 'The question is not, 'does everyone have to exercise?' The question is, 'if exercise and lifestyle don't explain everything, what are other things that explain this?'' Maybe it's genetics. But when it comes to superagers, currently 'we have more questions than answers,' Kramer says. Fortunately, researchers are working on this. Gefen is especially excited about the new discoveries the Northwestern brain bank may bring; for example, her team is investigating what makes von Economo neurons special and their role in disease resistance. 'You can just imagine what the future holds in that SuperAging brain bank.'

Parents pack survival kits for college-bound kids — Narcan, Plan B included
Pencils, notebooks — and Narcan? Concerned parents of incoming college freshmen are adding the life-saving nasal spray to back-to-school lists this year — along with condoms, Plan B and more modern must-haves that might have been unthinkable a generation ago. And that's just fine with students like Summer, 20, who said they prefer a matter-of-fact approach to the way campus life is lived now. Advertisement 8 Narcan, an opioid antagonist, is rising as a top back-to-school necessity for college kids heading to campus in the fall. Getty Images 'I administered Narcan to a girl who was passed out on the front lawn of an off-campus frat party,' the psych major from North Carolina, who didn't want to use her last name, told The Post. 'It literally saves lives.' Narcan, officially known as Naloxone, is an opioid antagonist that reverses the effects of illicit substances, such as fentanyl. Advertisement It's a serious topic of discussion among older folks with chickadees poised to leave the nest. From Facebook mom groups to viral TikTok clips, 'college survival kits' with the miracle medication are all the rage — along with contraception pills and other grown-up adds. 8 Sophia Green and her mom, Jamie, went viral after revealing the Narcan and Plan B pills packed in the teen's college survival kit. Courtesy Jamie Green Idaho mom Jamie, 42, and daughter Sophia Green, 18, recently made a big splash with a social media reveal of their list of nontraditional necessities for Sophia's first day of classes at Boise State University this fall. Advertisement And while the 5.6 million viewers of their clip were largely supportive, digital detractors downed the trend, arguing that plying adolescents with the preventative products is 'sad' and 'embarrassing.' One contrarian commenter even wrote, 'Damn, teach your daughters common sense, resilience and willpower.' Protesters of the ultra-progressive shift may rush to shame so-called 'helicopter parents' for inadvertently giving teens the green light to experiment. Advertisement But Yamalis Diaz, an adolescent psychologist at NYU Langone Health, said cautious adults are neither overstepping boundaries with their kids — nor granting them permission to party. Instead, they're simply preparing the pups for real-world eventualities. 8 Narcan is commonly administered through the nose and counteracts the effects of an opioid overdose. Dennis A. Clark 'Millennials and Gen Xers, who grew up in a very flexible, open-minded time, are now sending their Gen Z children off to college fully equipped to handle difficult situations,' Diaz told The Post. 'If parents choose to get Narcan or condoms for their kids, the message isn't, 'Here, go do drugs and have sex,' ' she insisted. 'The message is, 'I don't want you to get into any kind of tricky predicaments, but here are some tools that you can use to make smart choices after the fact.' ' It's a message that youngsters need now more than ever, statistics show. An alarming 50,000 teenagers confessed to misusing fentanyl, a synthetic opioid, in 2023, per a recent report from the Substance Abuse and Mental Health Services Administration, a branch of the Department of Health and Human Services. Researchers discovered a 47% spike in teen fentanyl use from 2022 to 2023. They attributed the startling uptick to the fact that many youngsters could have taken it without realizing. Advertisement Representatives for the Drug Enforcement Administration have deemed fentanyl, a Schedule I drug, the 'leading cause of death for adults ages 18 to 45 in the US,' according to the DEA's Campus Drug Prevention site. Summer's distressed schoolmate could have ended up just another statistic — but luckily, the quick thinker had taken an on-campus harm reduction seminar and knew what to do. 'She was super pale, her breathing was shallow and her pupils were pinpoint, which is a sign of overdose,' she recalled. Advertisement Now, she's always prepared with a supply of the medication, which is available as an over-the-counter commodity at most nationwide drugstores and online outlets like Amazon, where it costs around $45. 'I always keep Narcan in my purse when I go to college events, parties and festivals — because you just never know,' she said. 'Better to be safe than sorry.' 8 Gretchen is proudly giving her daughter all of the tools she needs to navigate difficult situations during the upcoming semester. Courtesy Gretchen Schaefer Maine mama Gretchen Schaefer, 50, who's sending her daughter, Ingrid, 19, back to school with a stash of Narcan and Plan B, agrees. Advertisement In fact, the mother of two said she's encouraging others with college kiddos to follow suit. 'The most common objection I hear is, 'Well, my kid doesn't hang out with drug users,' ' said Schaefer, noting that Ingrid kicks it with the sober crowd at her school in Massachusetts. 'But what if someone was slipped something and they have to reverse an overdose?' @snappity207 I made my kid a health kit for college instead of buying a prepackaged first aid kit. She may not need a few of these things, but knows to share if someone does and I will happily resupply. #college #dormhaul #firstaid #backtoschool ♬ original sound – Gretchen's Kitchen The vigilant mom is also keen on reversing the effects of unprotected sex. Advertisement 'In the case of sexual assault, I want her or someone on her dorm floor to have the Plan B on hand,' she added. 'It was $6 at Costco.' To ensure that Ingrid knows how and when to use all of the remedies in her 'health kit,' Schaefer's even created, printed and laminated an emoji-coded list of detailed instructions. Schaefer's medicine how-to prompts include, 'Can't poop? Take 2 SennaLax before bed,' and 'Oops, condom broke? Take 1 Plan B ASAP after unprotected sex (within 72 hours).' 8 As an extra precaution, Schaefer curated a detailed list of all the medical emergency items, their uses and recommended dosages in Ingrid's college health kit. Courtesy Gretchen Schaefer 8 Schaefer tells The Post that she purchased the Narcan, Plan B contraceptive pills and other emergency health supplies for Ingrid because there aren't many pharmacies near the teen's school. Getty Images She's not being overprotective; she's simply passing the torch. 'I'm the Swiss Army knife mom,' said Schaefer. 'I want her to be the Swiss Army knife roommate.' Jamie Green wants her Sophia to gain a similar reputation around the dorms. 8 Jamie says her family openly discusses drug and sex safety practices. Courtesy Jamie Green. 'It super important to be prepared,' Jamie, a social worker who's also at Boise State pursuing a master's degree, told The Post. She hopes Sophia's new crop of college friends feels comfortable turning to her for support when necessary. 'The Narcan and Plan B aren't necessarily for Sophia, but they're for anyone on campus in need,' said Jamie. 'They can confidentially come to her and get help.' 8 Sophia dreams of becoming a doctor who specializes in women's health and care. Courtesy Jamie Green Sophia, an aspiring OB/GYN, looks forward to being a safe haven over the next four years. 'My mom and I have always had a very open relationship, and it feels really great that she's setting me up for success in case of any emergencies because s–t happens,' said Sophia. 'It's better to be prepared than keeping secrets, lying and maybe ending up in a worse situation. 'I'm glad other girls in my dorm will be able to trust me or my mom if they don't have anyone else.'
