Prostate Cancer

Prostate Cancer: Introduction

Prostate cancer is one of the most common types of cancer in men and a leading cancer killer. Prostate cancer occurs when there is an uncontrolled growth of cancer cells that form a malignant tumor in the prostate. The prostate is an organ of the male reproductive system located below the bladder and around the urethra. The prostate produces a portion of the seminal fluid, a component of semen that supports the sperm.

Normally, cells in the prostate that are old or damaged will stop dividing and die before they can become cancerous. These cells are normally replaced by healthy young cells. Prostate cancer occurs when old or damaged cells to continue to divide and multiply uncontrollably. Untreated and/or advanced prostate cancer can grow and spread (metastasize) to other organs of the body such as the liver, bones, lungs and brain, and eventually become terminal.

It is not known exactly why prostate cancer occurs, but risk factors for developing it include a close family history of prostate cancer, being over 50 years of age, or being African-American.

Prostate cancer is most curable if caught in the earliest stages of the disease. However, there are often no symptoms of prostate cancer, especially in early stages. When symptoms do occur they typically involve alterations and difficulties with urination. For more information about symptoms, refer to symptoms of prostate cancer.

Diagnosing prostate cancer and its stage of advancement begins with taking a thorough personal and family medical history, including symptoms and risk factors for prostate cancer. Diagnosis also includes completing a physical examination. A digital rectal exam will be performed by the physician or nurse practitioner. This involves inserting a gloved finger into the rectum to palpate the prostate, feeling for any abnormalities that may indicate prostate cancer, such as lumps or a hard area. This is a routine screening procedure for men at risk for prostate cancer.

A screening blood test called a PSA is generally recommended to be done on a regular basis for men who are at risk for prostate cancer. High levels of PSA in the blood can indicate prostate cancer, as well as other conditions, such as prostatitis and benign prostatic hyperplasia.

Imaging test may include a transrectal ultrasound, which uses sound wave technology to create a picture of the prostate. Definitive diagnostic testing requires a transrectal biopsy of prostate. A biopsy involves taking samples of prostate tissue to examine under a microscope for the presence of cancer cells. Prostate cells are removed using a very small needle that is inserted through the rectum. This is generally done as an outpatient procedure.

Other tests, especially imaging tests, may be done to help determine a diagnosis and to evaluate how far prostate cancer has spread. These can include ultrasound, CT, MRI, nuclear medicine scan, and X-ray.

A diagnosis of prostate cancer can be missed or delayed because there may be no symptoms, especially in early stages of the disease. Additionally, some symptoms are similar to symptoms of other conditions. For more information about misdiagnosis and diseases and disorders that can mimic prostate cancer, refer to misdiagnosis of prostate cancer.

Prognosis of prostate cancer varies depending on the specific type of cancer cells, the stage of advancement, a patient's age, medical history, coexisting diseases and other factors. Treatment of prostate cancer varies, depending on the stage of advancement of the disease and other factors. For more information on treatment, refer to treatment of prostate cancer. ...more »

Definitions of Prostate Cancer:

Prostate adenocarcinoma is one of the most common malignant tumors afflicting men. The majority of adenocarcinomas arise in the peripheral zone and a minority occur in the central or the transitional zone of the prostate gland. Grading of prostatic adenocarcinoma predicts disease progression and correlates with survival. Several grading systems have been proposed, of which the Gleason system is the most commonly used. Gleason sums of 2 to 4 represent well-differentiated disease, 5 to 7 moderately differentiated disease and 8 to 10 poorly differentiated disease. Prostatic-specific antigen (PSA) serum test is widely used as a screening test for the early detection of prostatic adenocarcinoma. Treatment options include radical prostatectomy, radiation therapy, androgen ablation and cryotherapy. Watchful waiting or surveillance alone is an option for older patients with low-grade or low-stage disease. --2002 - (Source - Diseases Database)
