Context: Former US President Joe Biden has been diagnosed with Stage 4 metastatic prostate cancer, drawing global attention to the disease, its symptoms, and treatment options.

About Prostate Cancer:

• What is Prostate Cancer?

• Prostate cancer arises in the prostate gland, a small organ in men that produces seminal fluid. It is one of the most common cancers in men, particularly after age 50.

• Global and Indian Scenario:

• Globally: Prostate cancer is the 2nd most diagnosed cancer in men with over 1.4 million new cases and nearly 400,000 deaths in 2022 (GLOBOCAN). India: It ranks among the top 10 cancers in men, with 37,948 new cases and 18,386 deaths in 2022, and rising incidence in urban areas.

• Causes and Risk Factors:

• Age: Risk increases sharply after age 50. Family History: A close relative with prostate cancer doubles one’s risk. Genetics: BRCA1/2 mutations and Lynch syndrome increase vulnerability. Race: Men of African ancestry have higher risk and severity. Diet & Lifestyle: High intake of red meat, fats, and sedentary habits contribute.

• Common Symptoms of Prostate Cancer:

• Frequent or painful urination: Indicates urinary tract irritation due to prostate enlargement or tumor pressure. Weak urine flow or dribbling: Caused by blockage in the urethra due to prostate gland swelling. Erectile dysfunction: Tumor or treatment may impair nerves or blood vessels linked to erection. Blood in urine or semen: A sign of inflammation, prostate damage, or tumor-related bleeding. Bone pain (in advanced stages): Metastatic cancer often spreads to bones, causing persistent pain.

• Diagnosis Methods:

• PSA Blood Test: Detects elevated prostate-specific antigen, often a marker of cancer presence. Digital Rectal Exam (DRE): A doctor manually examines the prostate for lumps or hardness. Biopsy: Tissue samples from the prostate confirm cancer by microscopic analysis. Imaging (MRI/Bone Scans): Helps determine how far the cancer has spread within the body.

• Treatment Options:

• Active Surveillance: Regular monitoring without immediate treatment for low-risk cancers. Surgery (Prostatectomy): Surgical removal of the prostate to eliminate localized cancer. Radiation Therapy: Targets and destroys cancer cells using focused radiation beams. Hormone Therapy: Lowers testosterone levels to slow or stop cancer cell growth. Chemotherapy & Immunotherapy: Used when cancer is advanced or unresponsive to other treatments.
