Prostate Cancer Causes

The hormonal dependence of prostate cancer – and hence the usefulness of hormonal substances in its treatment – seems to indicate that androgens are involved in its appearance. However, it has not been possible to establish the relationship of other factors such as genetic, environmental or infectious factors with this type of cancer.

There are, however, a series of risk factors that may favor the appearance of prostate cancer, and they are listed below:

Prostate Cancer Risk Factors

  • Age: It usually appears from the age of 45, and the chances of developing this type of cancer increase with age.
  • Race: It is more frequent and more aggressive in black men. Among African Americans, these tumors tend to start earlier and grow faster.
  • Genetic factors: having relatives with prostate cancer increases the risk of suffering from it 2 to 3 times, the closer the relationship with the patient (parents, siblings or children).
  • Diet: the consumption of animal fat, especially red meat, and high-fat dairy, increases the risk. A diet low in fruits and vegetables could also have an impact. Conversely, vegetables, such as tomato and soy , and other foods, such as salmon , could protect against the appearance of these tumors.
  • Hormones elevated testosterone and IGF-1 (insulin growth factor) are related to an increased risk.
  • Ejaculatory frequency: It seems that having five or more weekly ejaculations has a protective effect.
  • Obesity: Like many other cancers, obesity increases the risk of developing prostate cancer.
