Prostate Cancer

Prostate cancer is the most common cancer and the second leading cause of cancer-related death among men in the United States, characterized by malignant growth of glandular cells in the prostate gland, typically presenting as adenocarcinoma originating in the peripheral zone. It often progresses slowly but can be aggressive, with potential to spread locally or metastasize to bones, lymph nodes, lungs, liver, or brain. Risk factors include age (most cases occur in men over 50), race (African American men have higher incidence and mortality), family history, and genetic predisposition, with 5–10% of cases being hereditary. The disease may remain asymptomatic in early stages, but symptoms can include urinary difficulties, frequent urination, blood in urine, erectile dysfunction, and bone pain. Diagnosis relies on prostate-specific antigen (PSA) screening, digital rectal examination, and confirmatory biopsy with Gleason scoring for grading. Staging classifies the disease as localized (confined to the prostate), locally advanced (spread beyond the prostate but not distant), or metastatic (distant spread). Early detection remains crucial, although treatment decisions are influenced by the cancer’s aggressiveness and individual risk profile. Lifestyle factors such as diet and physical activity may modulate risk, and while many cases are indolent and may not require immediate intervention, appropriate management based on histopathological findings and staging is essential for optimal outcomes.
