Prostate Cancer
Risks
and Causes
The cause of this cancer is not established
but hormonal, genetic, environmental and dietary factors are involved
in some cases. The male sex hormone testosterone aids the growth of prostrate
cancer cells. Risk increases with age more rapidly than any other cancer.
Men who have a history of prostate cancer in their family, especially a close
relative such as father, brother etc are at an increased risk. Racial predisposition
is another factor, incidence of prostrate cancer is highest in Blacks and lowest
in Asians.
Inhalation or ingestion of chemicals such as cadmium, a mineral found
naturally in certain foods and cigarette smoke, plastics, paints, nickel cadmium
batteries etc increases the risk for developing prostate and lung cancer.
People
involved in battery manufacture, welding, soldering, manufacture of paint, plastic,
cadmium alloy, textile etc are at high risk. A diet high in animal fat also has
been implicated in the development/increased risk of prostate cancer.
