Overview
Prostate cancer begins when cells in the prostate grow out of control. The prostate is part of the male reproductive system and helps make semen. Some prostate cancers stay confined to the gland for a long time, while others grow faster or spread to other parts of the body.
Key Symptoms
Early prostate cancer may cause no symptoms at all. When symptoms do happen, they can include trouble starting urination, weak urine flow, needing to urinate often, blood in the urine or semen, or pain with urination. If cancer has spread, some people may develop bone pain, unexplained weight loss, or fatigue.
Causes and Risk Factors
The exact cause is not fully understood, but prostate cancer develops from changes in prostate cells. Risk rises with age and is higher in people with a close family history of prostate cancer. Certain inherited gene changes can raise risk, and risk patterns differ across populations.
Who Is Affected
Prostate cancer mainly affects older men and others who have a prostate. It is uncommon in younger adults but becomes more common with increasing age. Family history and inherited risk can matter, so a person's background may influence when screening discussions should start.
Prevention
There is no guaranteed way to prevent prostate cancer. A general healthy lifestyle, including regular physical activity, maintaining a healthy weight, and eating a balanced diet, supports overall health. People at higher risk may benefit from discussing screening options earlier with a healthcare professional.
Diagnosis and Tests
Evaluation may start with a medical history, symptom review, and physical exam. Tests can include a prostate-specific antigen (PSA) blood test and a digital rectal exam, although these do not diagnose cancer on their own. If cancer is suspected, imaging such as MRI and a prostate biopsy may be used to confirm the diagnosis and assess how aggressive it appears.
Treatment Categories
Treatment depends on the cancer stage, how fast it seems to be growing, symptoms, age, and overall health. Options may include active surveillance, surgery, radiation therapy, hormone therapy, chemotherapy, targeted therapy, or other medicines. A care team can explain the possible benefits, limits, and side effects of each approach.
Living With It
Living with prostate cancer can involve ongoing monitoring, treatment side effects, and emotional stress. Some people may have urinary, bowel, sexual, or hormone-related changes that affect daily life. Follow-up care, symptom tracking, and support from healthcare professionals, family, or support groups can be helpful.
When to Seek Medical Care
Seek medical care if you notice urinary changes that do not go away, blood in the urine or semen, pelvic discomfort, or unexplained bone pain. Also make an appointment if you have a strong family history of prostate cancer or questions about screening. Prompt evaluation is important because symptoms can have many causes, including cancer.
When It May Be an Emergency
Get urgent medical help if you cannot pass urine, have severe back pain with new leg weakness or numbness, lose control of bladder or bowel function, or have heavy bleeding in the urine. These symptoms can signal serious complications that need immediate evaluation.
