Prostate Cancer

Symptoms 

• A weak or interrupted urine flow, difficulty starting urination, or the need to urinate frequently, especially at night, are common symptoms.
• Though less common, seeing blood in your urine or semen could be a sign of prostate issues.
• Some men experience trouble achieving or maintaining an erection.
• Unexplained pain in the hips, pelvis, or lower back can sometimes indicate advanced prostate cancer.

Causes and Risk Factors

• Prostate cancer is most commonly diagnosed in men over 50. The risk increases significantly with age.
• Men with a father, brother, or other close relatives who have had prostate cancer are at a higher risk of developing it.
• African American men are more likely to develop prostate cancer than men of other races, and they are more likely to be diagnosed at an advanced stage.
• Certain inherited gene changes, such as BRCA1 and BRCA2 mutations, can increase the risk of prostate cancer.
• Some research suggests that a diet high in red meat and dairy, and low in vegetables, may increase prostate cancer risk, though this is still being studied.

Diagnosing Prostate Cancer

• Prostate-specific antigen (PSA) test: This blood test measures the level of PSA, a protein produced by the prostate. Higher levels of PSA can indicate prostate cancer, but they can also be caused by benign conditions.
• Digital rectal exam (DRE): During this physical exam, a doctor inserts a finger into the rectum to feel for any abnormalities on the prostate.
• Biopsy: A small sample of prostate tissue is taken and analyzed to confirm the presence of cancer cells.

Treatment Options

• Active Surveillance (Watchful Waiting): For men with low-risk or early-stage prostate cancer, doctors may recommend closely monitoring the cancer rather than treating it immediately. Regular PSA tests, DREs, and sometimes biopsies can help men avoid the side effects of more aggressive treatments.

• Surgery: Surgical removal of the prostate, known as a prostatectomy, can be done using traditional open surgery or minimally invasive techniques like robotic surgery. Surgery is generally recommended for men with cancer confined to the prostate.

• Radiation Therapy: Radiation therapy uses high-energy rays to kill cancer cells. It’s often used as an alternative to surgery or in combination with other treatments. External beam radiation delivers radiation from outside the body, while brachytherapy involves implanting radioactive seeds directly into the prostate.

• Hormone Therapy: Prostate cancer growth is often fueled by testosterone. Hormone therapy reduces or blocks the body’s production of testosterone, helping slow the growth of cancer cells. It’s typically used for more advanced stages of cancer.

• Chemotherapy: Chemotherapy is sometimes used for prostate cancer that has spread outside the prostate or when hormone therapy is no longer effective. It involves drugs that kill rapidly dividing cancer cells and may help shrink tumors and control symptoms.

• Targeted Therapy: Targeted therapies focus on specific genetic changes in cancer cells. These treatments can be effective for men whose cancers have specific mutations.
