Breast cancer survivors may have lower risk of developing Alzheimer's disease, study finds
Cancer is not typically associated with health benefits, but a new study suggests that it could reduce the risk of dementia for some patients. A study led by the Seoul National University College of Medicine suggests that breast cancer survivors could have a slightly lower chance of developing Alzheimer's disease compared to those who had not undergone treatment. In the study, which was published in JAMA Network Open, data from more than 70,000 breast cancer survivors were compared to a cancer-free control group for an average of 7.3 years. FDA APPROVES FIRST AI TOOL TO PREDICT BREAST CANCER RISK Overall, the breast cancer survivors — particularly those who were 65 and older — showed an 8% lower risk of dementia within the five years following treatment. Those who received radiation showed the most risk reduction, the researchers found. The study was adjusted for other factors that could have contributed to Alzheimer's risk, including age, income levels, geographic location, body mass index, comorbidities (diabetes, hypertension, high cholesterol and chronic kidney disease) and health-related behaviors (smoking, alcohol consumption and physical activity), the study stated. This outcome conflicts with previous concerns about breast cancer patients experiencing cognitive decline after treatment. BILL GATES REVEALS 'NEXT PHASE OF ALZHEIMER'S FIGHT' AS HE SHARES DAD'S PERSONAL BATTLE Chemotherapy has previously been linked to a condition called "chemo brain," where patients experience cognitive decline. "Chemo brain refers to cognitive dysfunction, including thinking and memory problems, that occur in patients with cancer during and after chemotherapy," the researchers wrote. RATES OF DEMENTIA ARE LOWER IN PEOPLE WHO EAT THIS SPECIFIC DIET, RESEARCH SHOWS This is different from Alzheimer's, however — with "chemo brain," the cognitive impairment is described as "subtle" and doesn't keep the patient from retrieving remote memories. "Concerns about chemo brain and the long-term adverse effects of breast cancer treatment on cognition are common, but our findings suggest that this treatment does not directly lead to AD," the researchers noted. In fact, they stated, some studies have shown that certain drugs given to breast cancer patients can help to reduce the formation of amyloid-beta and tau proteins in the brain, which is one of the hallmarks of Alzheimer's. Based on the findings, the researchers recommend that breast cancer patients take steps to reduce modifiable risk factors for Alzheimer's, such as smoking and diabetes, along with receiving standard cancer treatment. Study limitations The study did have some limitations, the team acknowledged. Information about patients' breast cancer stage and radiation dose was not available. It is also possible that the number of Alzheimer's diagnoses was underestimated. Also, because the study focused on patients with "operable" breast cancer, it may not represent the risk of Alzheimer's among elderly patients, those with "critical comorbidities" or patients with advanced-stage disease, the researchers noted. CLICK HERE TO GET THE FOX NEWS APP "We could not evaluate the long-term increase in AD risk because our follow-up period was relatively short (maximum, 11 years)," they wrote. "Additional studies with long-term observation periods are warranted to examine long-term associations between AD risk and breast cancer survival duration." Maria C. Carrillo, Ph.D., Alzheimer's Association chief science officer and medical affairs lead in Chicago, pointed out that this topic of research has been explored in previous studies. "There have been many published reports from observational studies of cancer survivors with decreased risk of Alzheimer's disease, but also some that found increased risk," Carrillo, who was not involved in this most recent study, told Fox News Digital. CLICK HERE TO SIGN UP FOR OUR HEALTH NEWSLETTER The expert cautions against drawing "abrupt conclusions" based on this study. "Previous research on cancer survival and treatment and Alzheimer's risk, much of it cited by the authors of this article, has produced mixed — even contradictory — results," Carrollio said. "More research is needed — especially longer studies in more representative study populations." The most interesting aspect of this study, Carrillo said, is the finding that radiation therapy was associated with 23% Alzheimer's risk reduction, while other cancer treatments showed no risk reduction. This could be due to radiation's capability to lower inflammation levels, the expert suggested. For more Health articles, visit "Lowering inflammation in the body and brain can reduce amyloid beta or slow amyloid beta production, delaying the onset of symptomatic Alzheimer's," she said. "More research is needed to see if this is, in fact, the case." Approximately 7.2 million Americans aged 65 and older are currently living with Alzheimer's, according to the Alzheimer's Association. Fox News Digital reached out to the study researchers for comment.

India orders its airlines to check fuel switches on Boeing jets
By Abhijith Ganapavaram , Reuters An investigation team inspects the wreckage of Air India flight 171 a day after it crashed in a residential area near the airport, in Ahmedabad on 13 June, 2025. Photo: SAM PANTHAKY / AFP India has ordered its airlines to examine fuel switches on several Boeing models, while South Korea said it would order a similar measure, as scrutiny intensified of fuel switch locks at the centre of an investigation into a deadly Air India crash . The moves by India and South Korea came despite the planemaker and the US Federal Aviation Administration telling airlines and regulators in recent days that the fuel switch locks on Boeing jets are safe. The locks have come under scrutiny following last month's crash of an Air India jet, which killed 260 people. A preliminary report found that the switches had almost simultaneously flipped from run position to cutoff shortly after takeoff. The report noted a 2018 advisory from the US Federal Aviation Administration (FAA), which recommended, but did not mandate, operators of several Boeing models including the 787 to inspect the locking feature of fuel cutoff switches to ensure they could not be moved accidentally. India's Directorate General of Civil Aviation said it had issued an order to investigate locks on several Boeing models including 787s and 737s, after several Indian and international airlines began making their own inspections of fuel switches. The regulator oversees the world's third-largest and fastest-growing aviation market and its move raises the stakes for Boeing, whose aircraft are used by three of the country's four largest airlines. A spokesperson for the South Korean transport ministry said checks there were in line with the 2018 advisory from the FAA, but did not give a timeline for them. Boeing referred Reuters' questions to the FAA, which was not immediately available to comment outside regular hours. The company's shares were up 1.4 percent in US premarket trading. Some other global airlines were weighing their own inspections or had begun their own checks. In a statement, Japan's JAL said safety was its top priority, adding, "We are closely monitoring the investigation into the incident and will implement any necessary inspections based on its findings." Over the weekend, Air India Group started checking the locking mechanism on the fuel switches of its Boeing 787 and 737 fleets and has discovered no problems yet, a source familiar with the matter told Reuters. About half the group's 787s have been inspected and nearly all its 737s, the source added, speaking on condition of anonymity. Inspections were set to be completed in the next day or two. On Sunday (local time), citing a document and sources, Reuters reported that the planemaker and the FAA had privately issued notifications to airlines and regulators that the fuel switch locks on Boeing planes were safe and checks were not required. The Air India crash preliminary report said the airline had not carried out the FAA's suggested inspections as the FAA's 2018 advisory was not a mandate. It also said maintenance records showed that the throttle control module, which includes the fuel switches, was replaced in 2019 and 2023 on the plane involved in the crash. In an internal memo on Monday, Air India CEO Campbell Wilson, a New Zealander, said the investigation into the crash was far from over and it was unwise to jump to premature conclusions, following the release of the preliminary report. - Reuters

Indian regulator orders airlines to check Boeing fuel switches after plane crash report
India's aviation regulator has ordered the country's airlines to examine fuel switches on Boeing aircraft, after a preliminary report on the Air India flight 171 crash in June showed the fuel supply had been cut seconds after takeoff. The Directorate General of Civil Aviation said it had issued the order after several domestic and international airlines began making their own inspections of the locking mechanisms attached to the switches. South Korea was also preparing to order all airlines in the country that operate Boeing jets to examine the switches. A preliminary report, released on Saturday, found both engines of the Boeing 787 Dreamliner, which crashed, killing 260 people, had been starved of fuel, leading investigators to focus on the fuel switches in the cockpit. There has been online speculation about two competing theories – one of pilot error or sabotage, and one of faulty fuel switch locks – although Air India has cautioned that the investigation is in its early stages and there have been no recommended actions against Boeing. Air India's CEO, Campbell Wilson, said in a memo to staff on Monday that the report had 'triggered a new round of speculation in the media' after providing 'both greater clarity and opened additional questions'. Wilson added: 'The preliminary report identified no cause nor made any recommendations, so I urge everyone to avoid drawing premature conclusions as the investigation is far from over.' The report, by India's Aircraft Accident Investigation Bureau (AAIB), had cited a voice recording from the flight deck in which it said one of the pilots was heard asking the other 'why did he cutoff?' The other pilot responded that he 'did not do so', according to the report. Both switches were moved back to allow fuel to flow, but the plane was too low and slow to recover. While the report is not intended to provide definitive answers but only lay out basic facts, it has led to theories suggesting one of the pilots had either turned off the fuel to both engines, either by mistake or to deliberately bring down the plane. The Indian Commercial Pilots' Association (ICPA) said it was 'deeply disturbed by speculative narratives … particularly the reckless and unfounded insinuation of pilot suicide'. 'There is absolutely no basis for such a claim at this stage,' it said in a statement on Sunday, adding, 'it is deeply insensitive to the individuals and families involved'. A separate theory is that the fuel switches, which are located just below the thrust levers, might have switched off by themselves. This is usually not possible as they operate independently and need to be lifted up to disengage a lock. Adding to concern around fuel switches, the preliminary accident report had cited a bulletin issued by the US Federal Aviation Administration (FAA) in 2018 that had recommended the locking mechanisms be checked on multiple variants of Boeing aircraft, including the 787, after the company had received reports that some 737 models had 'fuel control switches were installed with the locking feature disengaged'. However, the advisory only made recommendations and did not consider it to be 'an unsafe condition' that needed a mandated inspection. It was also issued in 2018 and related to so many different types of Boeing jets that it would probably have already been flagged if the locks were not working on operating fleets. Steve Giordano, a former airline captain who flies several Boeing planes including the 787, said he did not believe the issues were 'mechanical' or 'airplane related'. 'I'm not convinced it was suicide or intentional,' he wrote on X. 'I'm just convinced that the switches were moved by a human hand.'

BTS' return fuels hopes of boost to South Korea's economy
The return of K-pop phenomenon BTS is raising hopes that it can revive South Korea's slowing economy, which has been weighed down by uncertainties over US tariffs and domestic political turmoil. The Korea Culture and Tourism Institute previously estimated that a single BTS concert in Seoul could inject up to US$895 million into the Korean economy and create as many as 10,000 jobs. BTS will make its comeback as a full group with a new album and tour in spring next year. CNA's senior Korea correspondent Lim Yun Suk reports.

Samsung Galaxy S25 FE will have improved charging, unlike the Galaxy Tab S10 Lite
Samsung's upcoming Galaxy S25 FE has recently been rumored to come with support for 45W wired charging, a marked increase from its predecessor's 25W capability. Now, thanks to a TÜV Rheinland certification, this has been confirmed. Naturally, don't expect the phone to come with a charger in the box. TÜV Rheinland has also certified the Galaxy Tab S10 Lite, and unfortunately this tablet didn't get the same treatment as the S25 FE, thus it will only go up to 25W charging. Samsung Galaxy S25 FE (left) and Tab S10 Lite (right) certifications All the other members of the Tab S10 family do support 45W, but limiting the Lite model to 25W is one of the corners cut in what we assume was the idea to keep the price low. Of course, the actual price of this device isn't official yet - the tablet itself is yet to be announced - so it remains to be seen whether that actually pans out. Still, it should be the cheapest of the Tab S10 models for sure. The Galaxy S25 FE and the Galaxy Tab S10 Lite could actually be launching together around October. Undoubtedly we'll be hearing a lot more about both until then, so stay tuned. Samsung Galaxy S24 FE Via
