What prostate cancer screening tests can evaluate my risk?

Question

Hello doctor,

My 67-year-old brother was diagnosed with prostate cancer a few months ago, and it has understandably made me concerned about my own risk.

Could you please explain whether prostate cancer runs in families and how likely it is that I might develop it as well?
Are any early screening options or tests available to help assess my personal risk?

I am also interested in learning more about any lifestyle changes or preventive steps I can take. I have heard that diet and exercise might make a difference, but I would appreciate your guidance on how to stay proactive about my health.

Please help.

Thank you.

Hello,

Welcome to icliniq.com.

Thanks for reaching out, and I understand your concerns completely.

I understand how worried you must be about your brother’s diagnosis and your own health.

Prostate cancer (a type of cancer that starts in the prostate, which is a small gland in the male reproductive system) does have a genetic component, but several factors influence your personal risk, and there are proactive steps you can take.

Below are hereditary factors that increase the risk -

Having a close relative (such as a brother) with prostate cancer raises your risk. The risk climbs even higher if multiple family members are affected or if they were diagnosed at a younger age.
Certain inherited mutations can increase your odds. If prostate cancer is common in your family, genetic counseling is worth considering.

I am suggesting a few investigations to diagnose the condition -

PSA (prostate‑specific antigen) test: This is a blood test that checks PSA levels. Men at average risk usually start screening at age 50, but with your family history, you may want to begin around 40 to 45. Discuss timing and frequency with your doctor.
Digital rectal exam (DRE), when sometimes paired with the PSA test, allows a clinician to feel for prostate irregularities.
A genetic counselor can help determine whether testing for specific mutations would be helpful.

Lifestyle changes that may lower risk include the following -

Emphasize plant-based foods, like fruits, vegetables, whole grains, and legumes.
Limit red and processed meats as well as foods high in saturated fat.
Choose healthy fats; foods rich in omega-3s may be beneficial.
Aim for a diet high in antioxidant-rich foods.
Target at least 150 minutes of moderate activity per week. Physical activity also supports a healthy weight, which is important because obesity is linked to more aggressive prostate cancer.
A balanced diet and regular exercise help reduce the risk of aggressive disease.
Cutting back on alcohol and eliminating tobacco offer broad health benefits and may lower overall cancer risk.

Keep the conversation going with your healthcare provider about your family history and any concerns.

Early PSA screening, started sooner than the general recommendation, may be appropriate for you.

If your family history is significant, consider meeting with a genetic counselor to see whether genetic testing could clarify your risk profile.

I suggest you consult an oncologist for personalized guidance.

I hope this information is helpful. Please feel free to reach out again if you have more questions.

Thank you.
