The following are associated with an increased risk of advanced prostate cancer: Height, high body mass index, low physical activity, smoking, low tomato sauce consumption, high calcium intake, high linoleic acid intake, African-American lineage, and a positive family history.
No proven link exists between prostate cancer and an active sex life, vasectomy, masturbation, use of alcohol or tobacco, circumcision, infertility, infection of the prostate, or a common non-cancerous condition called benign prostatic hyperplasia (BPH). Most, if not all, men will experience an enlarged prostate as they age.
