Prostate Cancer Causes and Risk Factors in New York, NY
Prostate cancer is the second most common cancer in men, yet scientists still have not pinpointed one single cause. What we do know is that the disease begins when changes in the DNA of prostate cells cause them to grow out of control, and that certain factors make those changes more likely. At Prostate Cancer 911, Dr. David Samadi helps men understand their personal risk profile so they can start screening at the right time and catch cancer early.
What Causes Prostate Cancer?
Prostate cancer develops when genetic mutations in prostate cells switch on growth signals or switch off the mechanisms that normally stop cells from dividing. Some of these mutations are inherited from a parent, while others are acquired over a lifetime through aging, hormones, inflammation, and environmental exposures. Most cases arise from a combination of these influences rather than one cause.
The Major Risk Factors for Prostate Cancer
1. Family History
Men with a father or brother who had prostate cancer have about twice the average risk. Risk is higher still when multiple relatives are affected or when relatives were diagnosed at a young age. A family history of breast, ovarian, or pancreatic cancer can also signal an inherited mutation.
2. Inherited Gene Mutations
Mutations in BRCA1, BRCA2, HOXB13, and DNA repair genes linked to Lynch syndrome increase the likelihood of prostate cancer, and BRCA2 mutations are associated with more aggressive disease. Genetic counseling and testing may be recommended for men with a strong family history.
3. Race, Ethnicity, and Geography
African American men and Caribbean men of African descent are diagnosed more often and are more likely to develop aggressive prostate cancer. Prostate cancer is also more common in North America, northwestern Europe, Australia, and the Caribbean than in Asia, Africa, and Central and South America.
4. Age
Risk rises sharply after age 50. Roughly 6 in 10 prostate cancers are diagnosed in men 65 or older, and the average age at diagnosis is about 67.
5. Diet
Diets high in red meat, processed meat, and high-fat dairy, and low in fruits and vegetables, have been associated with higher risk. Our prostate cancer prevention page outlines a prostate-friendly eating plan.
6. Agent Orange and Chemical Exposure
Vietnam-era veterans exposed to Agent Orange have a higher risk of prostate cancer, and the VA recognizes it as a service-connected condition. Some studies also link firefighting and certain industrial chemical exposures to increased risk.
7. Lack of Physical Activity
A sedentary lifestyle contributes to weight gain and hormonal changes that may promote cancer growth. Regular exercise is linked to lower risk of aggressive prostate cancer.
8. Obesity
Obesity does not appear to raise the overall risk of being diagnosed, but it is associated with a higher risk of aggressive, advanced prostate cancer and with worse outcomes after treatment.
What Your Risk Profile Means for Screening
Knowing your risk factors helps determine when to start screening and how often to repeat it. Average-risk men should talk with a urologist about PSA testing around age 50. Higher-risk men, including African American men and those with a family history, should start at 45, and men with several affected relatives or known mutations may begin at 40.
Remember that having a risk factor does not mean you will develop prostate cancer, and many men diagnosed have no obvious risk factors at all. That is why routine screening matters for every man.

Prostate Cancer Risk Factor FAQs
What is the biggest risk factor for prostate cancer?
Age is the biggest risk factor. The chance of diagnosis rises steadily after 50, and most cases are found in men 65 and older.
Is prostate cancer hereditary?
It can be. Having a father or brother with prostate cancer roughly doubles your risk, and inherited mutations such as BRCA2 increase risk further.
Why are African American men at higher risk?
Researchers believe a combination of genetic, biological, and access-to-care factors contribute. African American men are more likely to be diagnosed and to develop aggressive disease, so earlier screening is recommended.
Does Agent Orange cause prostate cancer?
Exposure to Agent Orange is linked to a higher risk, and the VA recognizes prostate cancer as a presumptive service-connected condition for exposed veterans.
Does being overweight raise my risk?
Obesity is associated with a higher risk of aggressive prostate cancer and poorer outcomes after treatment, even though it may not raise the overall diagnosis rate.
If I have risk factors, will I definitely get prostate cancer?
No. Risk factors raise the likelihood, but many men with risk factors never develop the disease, and some men without them do.
When should I talk to a urologist about my risk?
If you are 45 or older, or 40 with a strong family history, schedule a consultation with Dr. Samadi or call (212) 365-5000.
