The causes of prostate cancer, as with other cancers, are broad and complex. There is no single perspective on what causes prostate cancer. There are, however, certain factors that are associated with an increased risk of developing prostate cancer.

Age & Genetics

What is known is that prostate cancer is somewhat rare in men under 50 years old, with the risk of developing prostate cancer increasing thereafter. By the time they are 80, more than half of all men will have some cancerous growth, which may or may not require treatment.

Prostate cancer seems to run in some families, suggesting an inherited or genetic factor. Having a father or brother with prostate cancer doubles a man's risk of developing this disease. The risk is even higher for men with several affected relatives, particularly if their relatives were young at the time of diagnosis. Scientists have identified several inherited genes that seem to increase prostate cancer risk.

Some inherited genes increase risk for more than one type of cancer. For example, inherited mutations of the BRCA1 or BRCA2 genes are the reason that breast and ovarian cancers are much more common in some families. The presence of these gene mutations also increases prostate cancer risk. But they are responsible for a very small percentage of prostate cancer cases.

Ethnic origin appears to play a part: men of African heritage seem to be at highest risk, and men of Asian descent are the lowest.

Diet & Lifestyle

Lifestyle choices, diet and exposure to environmental toxins are thought to play a part in the development and speed of prostate cancer.

Diets high in red meat, calcium (dairy products) and bad cholesterol (LDL) are thought to significantly increase prostate cancer risk. Diets high in grain carbohydrates can also affect insulin levels, which may result in obesity. Combined with dietary contributors towards obesity, a lifestyle with little exercise may also lead to development of prostate cancer. Men with a body mass index (BMI) of 32.5 or higher are 30% more likely to die from prostate cancer, while men with a BMI of 35 are 60% more likely to have a recurrence of prostate cancer in 3 years.

Diets that are rich in raw foods and vegetables are known to help prevent prostate cancer. Antioxidant foods help reduce “free radicals” in the body, which damage cell structure and may be a trigger for cancer development. Some common antioxidants include lycopene (found in tomatoes), pomegranate, mangosteen, wheatgrass and seabuckthorn, though the field of antioxidant discovery and research is ever-changing.

There is also research suggesting dietary or supplemented sources of omega 3 and 6 fatty acids, found predominantly in fish, can help prevent cancer, as well as having positive effects on the brain and cardiovascular function. Additionally, supplementation of selenium, vitamin D and vitamin E are thought to be beneficial in preventing prostate cancer as they can lower PSA levels and inhibit tumor growth.

da Vinci Treatment Options for Prostate Cancer


All surgery presents risk, including da Vinci Surgery. Results, including cosmetic results, may vary. Serious complications may occur in any surgery, up to and including death. Examples of serious and life-threatening complications, which may require hospitalization, include injury to tissues or organs; bleeding; infection, and internal scarring that can cause long-lasting dysfunction or pain. Temporary pain or nerve injury has been linked to the inverted position often used during abdominal and pelvic surgery. Patients should understand that risks of surgery include potential for human error and potential for equipment failure. Risk specific to minimally invasive surgery may include: a longer operative time; the need to convert the procedure to an open approach; or the need for additional or larger incision sites. Converting the procedure to open could mean a longer operative time, long time under anesthesia, and could lead to increased complications. Research suggests that there may be an increased risk of incision-site hernia with single-incision surgery. Patients who bleed easily, have abnormal blood clotting, are pregnant or morbidly obese are typically not candidates for minimally invasive surgery, including da Vinci Surgery. Other surgical approaches are available. Patients should review the risks associated with all surgical approaches. They should talk to their doctors about their surgical experience and to decide if da Vinci is right for them.
