Approximately 1 in 9 men will develop prostate cancer in their lifetime. The exact cause of prostate cancer is currently unknown. However, several factors have been identified that increase the risk of developing prostate cancer.

These factors include:

• Age: Prostate cancer is more common in older men. Most cases occur in men over 65 years old.
• Family history: Men with a family history of prostate cancer, particularly if their father or brother had the disease, are at a higher risk of developing prostate cancer themselves.
• Genetics: Certain inherited genetic mutations may contribute to higher risk of prostate cancer.
• Race and ethnicity: Prostate cancer is more common in African American men. Especially African American men over the age of 65.
• Hormones: Male hormones such as testosterone promote prostate cell growth. When too much testosterone causes cells to grow and divide too quickly, mutations can occur and can result in cancer.

It is important to note that having one or more of these risk factors does not necessarily mean that a man will develop prostate cancer. Regular screening and early detection can improve the chances of successful treatment if prostate cancer is detected.

Personalizing care is a focus of Dr. Tewari’s research group. Dr. Tewari’s team has developed multiple risk tools to help personalize risk assessment for prostate cancer. Explore Dr. Tewari’s latest research.
