Prostate Cancer

In North America, prostate cancer occurs in: 30 percent of men over 
age 70, 60 percent of men over age 80 and 90 percent of men over age 
90. 

We do not know what causes prostate cancer, but increased risk for 
prostate cancer is associated with:  Eating red meat cooked at high 
temperatures (Carcinogenesis, 10/30/2012).
 Lack of sunlight. Men who live in cities north of 40 degrees 
latitude (north of Philadelphia, PA, Columbus, OH, or Provo, UT) 
have the highest risk for dying from prostate cancer of any men 
in North America.
 Smoking cigarettes.

RISK FOR AGGRESSIVE PROSTATE CANCER: More than 95 percent of men 
with prostate cancer have a slow growing disease that will not harm 
them. However, about three percent will have an AGGRESSIVE disease 
that grows rapidly and can kill them. Factors that are associated 
with increased risk for aggressive prostate cancer include:
 smoking
 not eating lots of fruits and vegetables
 being overweight
 eating red meat
 being over six feet tall 
 not exercising
 eating foods rich in calcium (Cancer Epidemiology, Biomarkers & 
  Prevention, 11/07/2012)
 having a father or brother with prostate cancer
 exposure to toxic substances such as Agent Orange
 saturated fat (J Nat Can Inst 1995;87(9):652-661)
 where you live: for example, men who live in Scandinavian and 
  North American countries are at increased risk, compared to those 
  living in Asian countries.

FACTORS NOT ASSOCIATED WITH PROSTATE CANCER: We have no evidence 
that the following conditions increase a man's risk for developing 
prostate cancer: 
 enlarged prostate, called benign prostatic hyperplasia (BPH)
 a prostate infection
 alcohol
 having a vasectomy
 frequent ejaculations (some studies actually show decreased 
  incidence of prostate cancer in men who ejaculate frequently).
