  • One of the most common cancers in men >50 years of age 

Signs and Symptoms

  • Weak urinary stream
  • Polyuria, nocturia
  • Hematuria
  • Erectile dysfunction
  • Pelvic pain, back pain, chest pain
  • Lower extremity weakness or numbness
  • Loss of bladder or bowel control

Risk Factors

  • Age (increased risk in men >50 years old)
  • Positive family history (1st-degree relatives and relatives diagnosed with prostate cancer at an early age doubles the risk)
  • Ethnicity (African-American, Caribbean men of African ancestry)
  • Chemical exposures (toxic combustion products)
  • Genetic mutations: Breast cancer susceptibility gene 1 (BRCA1), breast cancer susceptibility gene 2 (BRCA2) mutations, deoxyribonucleic acid (DNA) mismatch repair genes [MutS Homolog 2 (MSH2), MutL Homolog 1 (MLH1), Lynch syndrome], insulin-like growth factor-1 (IGF-1)
  • Other risk factors under research include a positive medical history of inflammation of the prostate gland [eg prostatitis, STDs, proliferative inflammatory atrophy (PIN)] and vasectomy
