Prostate cancer is a disease in which malignant (cancer) cells form in the tissues of the prostate.
The prostate is a gland in the male reproductive system. It lies just below the bladder (the organ that collects and empties urine) and in front of the rectum (the lower part of the intestine). It is about the size of a walnut and surrounds part of the urethra (the tube that empties urine from the bladder). The prostate gland makes fluid that is part of the semen.
Prostate cancer is most common in older men. In the U.S., about 1 out of 8 men will be diagnosed with prostate cancer.
Signs of prostate cancer
These and other signs and symptoms may be caused by prostate cancer or by other conditions. Check with your doctor if you have any of the following:
Trouble starting the flow of urine.
Frequent urination (especially at night).
Trouble emptying the bladder completely.
Weak or interrupted ("stop-and-go") flow of urine.
When prostate cancer is detected in an advanced stage, symptoms may include:
Pain in the back, hips, or pelvis that doesn't go away.
Shortness of breath, feeling very tired, fast heartbeat, dizziness, or pale skin caused by anemia.
Other conditions may cause the same symptoms. As men age, the prostate may get bigger and block the urethra or bladder. This may cause trouble urinating or sexual problems. The condition is called benign prostatic hyperplasia (BPH), and although it is not cancer, surgery may be needed. The symptoms of benign prostatic hyperplasia or of other problems in the prostate may be like symptoms of prostate cancer.
Tests used to diagnose prostate cancer.
The following tests and procedures may be used:
Physical exam and health history: An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patient’s health habits and past illnesses and treatments will also be taken.
Digital rectal exam (DRE): An exam of the rectum. The doctor or nurse inserts a lubricated, gloved finger into the rectum and feels the prostate through the rectal wall for lumps or abnormal areas.
Prostate-specific antigen (PSA) test: A test that measures the level of PSA in the blood. PSA is a substance made by the prostate that may be found in higher than normal amounts in the blood of men who have prostate cancer. PSA levels may also be high in men who have an infection or inflammation of the prostate or BPH (an enlarged, but noncancerous, prostate).
PSMA PET scan: An imaging procedure that is used to help find prostate cancer cells that have spread outside of the prostate, into bone, lymph nodes, or other organs. For this procedure, a cell-targeting molecule linked to a radioactive substance is injected into the body and travels through the blood. It attaches to a protein called prostate-specific membrane antigen (PSMA) that is found on the surface of prostate cancer cells. A PET scanner detects high concentrations of the radioactive molecule and shows where the prostate cancer cells are in the body.
Transrectal magnetic resonance imaging (MRI): A procedure that uses a strong magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. A probe that gives off radio waves is inserted into the rectum near the prostate. This helps the MRI machine make clearer pictures of the prostate and nearby tissue.
Some types of standard treatment:
Watchful waiting or active surveillance
Watchful waiting and active surveillance are treatments used for older men who do not have signs or symptoms or have other medical conditions and for men whose prostate cancer is found during a screening test.
Watchful waiting is closely monitoring a patient’s condition without giving any treatment until signs or symptoms appear or change. Treatment is given to relieve symptoms and improve quality of life.
Active surveillance is closely following a patient's condition without giving any treatment unless there are changes in test results. It is used to find early signs that the condition is getting worse. In active surveillance, patients are given certain exams and tests, including digital rectal exam, PSA test, transrectal ultrasound, and transrectal needle biopsy, to check if the cancer is growing. When the cancer begins to grow, treatment is given to cure the cancer.
Other terms that are used to describe not giving treatment to cure prostate cancer right after diagnosis are observation, watch and wait, and expectant management.
Surgery
Patients in good health whose tumor is in the prostate gland only may be treated with surgery to remove the tumor. The following types of surgery are used:
Radical prostatectomy: A surgical procedure to remove the prostate, surrounding tissue, and seminal vesicles. Removal of nearby lymph nodes may be done at the same time.
Pelvic lymphadenectomy: A surgical procedure to remove the lymph nodes in the pelvis. A pathologist views the tissue under a microscope to look for cancer cells.
Transurethral resection of the prostate (TURP): A surgical procedure to remove tissue from the prostate using a resectoscope (a thin, lighted tube with a cutting tool) inserted through the urethra. This procedure is done to treat benign prostatic hypertrophy and it is sometimes done to relieve symptoms caused by a tumor before other cancer treatment is given. TURP may also be done in men whose tumor is in the prostate only and who cannot have a radical prostatectomy.
In some cases, the nerves that control penile erection can be saved with nerve-sparing surgery. However, this may not be possible in men with large tumors or tumors that are very close to the nerves.
Radiation therapy and radiopharmaceutical therapy
Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are different types of radiation therapy:
External radiation therapy uses a machine outside the body to send radiation toward the area of the body with cancer. Conformal radiation is a type of external radiation therapy that uses a computer to make a 3-dimensional (3-D) picture of the tumor and shapes the radiation beams to fit the tumor. This allows a high dose of radiation to reach the tumor and causes less damage to nearby healthy tissue.
Hypofractionated radiation therapy may be given because it has a more convenient treatment schedule. Hypofractionated radiation therapy is radiation treatment in which a larger than usual total dose of radiation is given once a day over a shorter period of time (fewer days) compared to standard radiation therapy. Hypofractionated radiation therapy may have worse side effects than standard radiation therapy, depending on the schedules used.
Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. In early-stage prostate cancer, the radioactive seeds are placed in the prostate using needles that are inserted through the skin between the scrotum and rectum. The placement of the radioactive seeds in the prostate is guided by images from transrectal ultrasound or computed tomography (CT). The needles are removed after the radioactive seeds are placed in the prostate.
Radiopharmaceutical therapy uses a radioactive substance to treat cancer.
The way the radiation therapy is given depends on the type and stage of the cancer being treated. External radiation therapy, internal radiation therapy, and radiopharmaceutical therapy are used to treat prostate cancer.
