The recent revelation of former US President Joe Biden's aggressive prostate cancer diagnosis has once again brought the spotlight to one of the most common cancers affecting older men. While prostate cancer is often treatable, Biden's case highlights the complexities of diagnosis and the importance of timely screening, even for those who undergo regular health checkups. Experts now question whether warning signs might have been missed and whether current screening guidelines need to be re-evaluated.

Prostate cancer, which affects over 300,000 men annually in the US is no longer rare in India either. Rising incidence in younger age groups, especially men in their early 50s, signals a shift in disease patterns that warrants urgent attention.
Firstpost spoke with Dr Sajjan Rajpurohit, Senior Director – Medical Oncology, BLK-Max Super Speciality Hospital to discuss various aspects such as detection, awareness, prevention and management of prostate cancer.
What is Prostate Cancer?
Prostate cancer develops when cells within the prostate gland begin to grow uncontrollably. This small gland, located beneath the bladder and in front of the rectum, is responsible for producing seminal fluid. It's a common malignancy; it's estimated that 1 in 8 men will be diagnosed with prostate cancer in their lifetime. In India, the incidence rate is also on the rise, attributed to increased awareness and improved diagnostic capabilities.
Early signs and symptoms
In its initial stages, prostate cancer often presents no symptoms, making early detection challenging without screening. However, as the disease progresses, men may experience:
*Frequent urination, particularly at night
*Difficulty starting or stopping urination
*Weak or interrupted urine flow
*Painful urination or ejaculation
*Blood in urine or semen
*Persistent pain in the back, hips, or pelvis
Men must be aware of these symptoms and consult a healthcare professional if they arise.
How is it diagnosed?
Diagnosis typically involves a combination of tests:
PSA Test: The Prostate-Specific Antigen (PSA) test measures PSA levels in the blood. Elevated levels can indicate prostate cancer or other prostate conditions.
Digital Rectal Exam (DRE): A doctor performs a DRE to manually examine the prostate gland through the rectal wall, checking for any abnormalities.
MRI: Magnetic Resonance Imaging (MRI) provides detailed images of the prostate and surrounding tissues, helping to pinpoint suspicious areas.
Biopsy: If initial tests suggest cancer, a biopsy is performed to confirm the diagnosis. This procedure involves taking small tissue samples from the prostate for microscopic examination.
Major risk factors
Several factors can increase a man's risk of developing prostate cancer:
Age: The risk increases significantly after age 50.
Genetics: A family history of prostate cancer, especially in close relatives, can elevate risk.
Lifestyle: Diets rich in red meat and dairy products, along with obesity, may contribute to increased risk.
Ethnicity: Prostate cancer is notably more common in African American men compared to men of other ethnicities.

Progression and treatment options
If untreated, prostate cancer can advance from a localized disease to an advanced stage, potentially spreading to nearby tissues and distant organs, leading to severe complications like bone pain and fractures. This underscores the importance of early detection and treatment.
Treatment options vary based on the cancer's stage:
Active Surveillance: For low-risk, localized cases, doctors might recommend monitoring without immediate intervention.
Surgery: Radical prostatectomy, the surgical removal of the prostate gland and some surrounding tissue, is often recommended for localized cancer.
Radiation Therapy: This method uses high-energy rays to target and destroy cancer cells, either as a primary treatment or post-surgery.
Hormone Therapy: This approach aims to lower male hormone levels that can fuel cancer growth, frequently used for advanced prostate cancer.
Chemotherapy: For advanced cases, chemotherapy may be employed to kill rapidly dividing cancer cells throughout the body.
Recent advancements, including targeted therapies and immunotherapy, are also showing considerable promise in improving patient outcomes.
Can it be cured?
Prostate cancer can often be cured, particularly when caught early. Survival rates for localized prostate cancer are very high, with nearly 100% of men surviving five years after diagnosis. However, survival rates decline for advanced stages, reinforcing the critical importance of early detection and timely treatment.
Age and treatment decisions
A patient's age significantly influences treatment decisions. Older individuals may have different health considerations, potentially leading to a choice for less aggressive treatments, while younger patients might opt for curative approaches. A thorough discussion with a healthcare provider is essential to determine the most suitable strategy for individual circumstances.
Role of lifestyle in prevention and recurrence
Lifestyle factors play a substantial role in both preventing prostate cancer and reducing its recurrence risk. Maintaining a healthy diet rich in fruits, vegetables and whole grains, combined with regular exercise and a healthy weight can help lower risk. Additionally, avoiding smoking and limiting alcohol consumption are vital preventive measures.
Importance of early detection
Early detection is paramount for successful prostate cancer treatment outcomes. Men, especially those at higher risk due to age or family history, should be encouraged to discuss screening options with their healthcare providers. Regular screenings, including PSA tests and DREs, can help identify the disease in its most treatable stages.

Donald Trump shares bizarre claim that Joe Biden was ‘executed in 2020' and replaced by clones
US President Donald Trump stirred controversy this weekend by sharing a post on his Truth Social account that claimed President Joe Biden died in 2020 and was replaced by 'clones, doubles & robotic engineered soulless mindless entities.' The post, originally from a small supporter account, has no credible evidence and comes amid renewed speculation over Biden's health following his recent cancer diagnosis. Late Saturday night, Trump reposted a message alleging Biden's death and replacement, writing no additional commentary. The original post stated: 'There is no #JoeBiden - executed in 2020. #Biden clones doubles & robotic engineered soulless mindless entities are what you see. Democrats don't know the difference.' Despite this dramatic claim, there is no factual basis for the theory. Biden has regularly made live public appearances, held unscripted press conferences, and interacted directly with world leaders. The repost by Trump followed news that President Biden was diagnosed with stage 4 metastatic prostate cancer, described by his office as aggressive but treatable. This announcement has ignited fresh debates about Biden's health and fitness for office, with critics questioning why the cancer was not detected earlier. Some speculate members of the previous administration were aware of the illness but kept it hidden to maintain Biden's political viability. The cancer diagnosis has also fueled theories linking Biden's medical condition to his performance in recent public appearances, including the June presidential debate. The revelation about Biden's cancer has led to calls within the MAGA community, including from Trump supporters, for an investigation into Biden's White House doctor. Critics question how Biden received a clean bill of health as recently as last July despite his advanced cancer diagnosis.

Doctor says your cramps and migraines are not really random: 'They could be signs your body is low on...'
If you've ever blamed that morning stiffness on 'just getting older' or brushed off random cramps and migraines as no big deal, it might be time to look a little deeper. According to Dr Kunal Sood, MD, Anesthesiology, these everyday aches and pains might actually be your body's way of waving a red flag and they're far from random. (Also read: Doctor shares 6 eye care tips to protect your vision during latest COVID-19 surge: 'Avoid unnecessary touching' ) In his May 31 Instagram post, Dr Sood breaks down the hidden signals our bodies send when something's off. 'If you live with pain and can't figure out where it's coming from, here's what most people don't get told,' he writes. He further breaks down what many people miss about pain and why understanding its root cause can be a game-changer for your health. A post shared by Kunal Sood, MD (@doctorsoood) If your joints feel achy and stiff when you wake up but ease up as the day goes on, don't just blame it on wear and tear. 'That pattern points to inflammation, not just getting old,' explains Dr Sood. In conditions like rheumatoid arthritis, the immune system tends to become more active overnight, which is why mornings can feel especially rough. Gentle movement helps circulate joint fluid and quiet down those inflammatory signals, which is why you start to feel better after getting out of bed. Think your cramps or migraines are just random? Think again. 'These might actually be signs your body is low on magnesium,' says Dr Sood. Magnesium plays a crucial role in muscle function and nerve signalling. When levels dip, which happens more often than you'd expect, muscles can misfire, leading to cramps. In the brain, low magnesium can destabilise blood vessels, triggering migraines. This is especially common in people who deal with high stress, poor sleep, or who engage in intense workouts. Pain doesn't just hurt, it changes how your brain works. 'Long-term pain can shrink parts of your brain,' Dr Sood explains. MRI studies have shown reduced grey matter in areas responsible for processing pain and regulating emotions. The good news? 'It's reversible.' When pain is managed properly, the brain can start to recover and heal itself. That's a powerful reason to take chronic pain seriously and treat it proactively. Not all pain stems from a visible injury. 'Sometimes, it's how you sit, move, or carry stress,' says Dr Sood. Poor posture or muscle imbalances can compress nerves, leading to symptoms like tingling, burning, or aching, even when there's no clear injury. In many cases, you don't need scans or meds just a closer look at your daily posture and movement habits might do the trick. 'Pain is complex, but it's not random,' Dr Sood concludes. 'The more you understand where it's coming from, the more control you get back.' Whether it's morning stiffness, sudden cramps, or migraines that just won't quit, your body might be trying to tell you something. And listening could be the first step toward real relief.
