Prostate cancer can sometimes be associated
with known risk factors for the disease. Many risk factors
are modifiable though not all can be avoided. Among those
factors that appear to aid in prevention are hormone medications,
diet adjustment and chemoprevention.
Studies are underway to discover the role of certain drugs,
such as finasteride, that reduce the amount of male hormone
as preventive agents for prostate cancer.
Diet and Lifestyle
A diet high in fat, especially animal fat, may be associated
with an increased risk of prostate cancer. Increased dietary
intake of fruits and vegetables has been associated with
a reduced risk of prostate cancer in some studies.
Chemoprevention is the use of specific natural or man-made
drugs, vitamins, or other agents to reverse, suppress, or
prevent cancer growth. Several agents, including difluoromethylornithine
(DFMO), isoflavonoids, selenium, vitamins D and E, and lycopene
have shown potential benefit in studies. Further studies
are needed to confirm this.
