Risk Factors and Symptoms for Prostate Cancer
There are numerous risk factors for prostate cancer that should be considered in determining the timing of screening and type of treatment for prostate cancer. Although age is the strongest risk factor (almost two-thirds of prostate cancers are found in men over the age of 65), race (African American men in particular are more likely to be diagnosed with prostate cancer) and family history are associated with greater risk of prostate cancer. The exact role of lifestyle (diet, exercise, smoking) has not been determined.
In its early stages, prostate cancer has no overt symptoms. Problems with urinating could be a sign of advanced prostate cancer, but it is also a symptom of enlarged prostate, or BPH (benign prostatic hyperplasia), and prostatitis.
Symptoms of advanced prostate cancer may include:
- Trouble having or keeping an erection (impotence)
- Blood in the urine
- Pain in the spine, hips, ribs, or other bones
- Weakness or numbness in the legs or feet
- Loss of bladder or bowel control
