a protein secreted by the epithelial cells of the prostate gland including cancer cells; an elevated level in the blood indicates an abnormal condition of the prostate gland, either benign or malignant; it is used to detect potential problems in the prostate gland and to follow the progress of PCA therapy (see SCREENING)
A PSA test is used as a screening test for prostate cancer. Elevated levels of PSA also may indicate prostate injury, infection, or benign (non-cancerous) prostate enlargement.
Prostate specific antigen is an enzyme that is produced only by prostate cells and can be measured with a simple blood test. An elevated level raises the suspicion of prostate cancer.
a protein manufactured exclusively by the prostate gland; PSA is produced for the ejaculate where it liquifies the semen and allows sperm cells to swim freely; elevated levels of PSA in blood serum are associated with benign prostatic hyperplasia and prostate cancer
a protein made by the cells of the prostate gland that can signal increased growth of the prostate. Doctors perform a PSA test to check for prostate disease.
a test to detect prostate cancer. The test measures the levels of a specific antigen (a protein that under certain conditions can trigger a specific immune response) secreted by the prostate that shows elevated levels due to the presence of prostate cancer or benign prostatic hyperplasia. Found in normal seminal fluid and produced by prostatic epithelial cells, a rise in the enzyme may indicate cancer. An increase in the level of prostate specific antigen is also helpful to indicate the failure of treatment.
a 33000 molecular weight glycoprotein used as a marker in the early diagnosis and management of prostate cancer.
A substance manufactured by the prostate and found in the blood that often increases in cases of prostate cancer and other prostate conditions.
Substance produced by prostate cells found in the blood. The level can be measured by a blood test. If the level is much higher than normal, there may be a cancer in the prostate and further tests will need to be done. Can also be used as a marker in men diagnosed with prostate cancer - the level goes up when cancer is growing and falls when the cancer is shrinking.
(PSA) A marker used to determine prostate disease – may be benign or malignant.
A blood test that measures a substance manufactured solely by prostate gland cells. An elevated reading indicates an abnormal condition of the prostate gland, either benign or malignant. It is presently the most sensitive tumor marker for the identification and monitoring of prostate cancer.
a protein in the blood produced by prostate tissue that serves as a tumor marker.
an enzyme secreted by the prostate gland that is used as a marker for prostate disease.
(PSA) a protein that is manufactured only by the prostate and can be measured as an indicator of prostate cancer.
A protein that is specifically manufactured by prostatic epithelial cells. The level of PSA often correlates with the likelihood and extent of prostate cancer and the size of benign prostatic enlargement or BPH.
a gland protein made primarily by the prostate. Levels of PSA may be elevated for a number of benign reasons or prostate cancer. The PSA test is used to help find prostate cancer as well as to monitor the results of treatment.
a gland protein made by the prostate. Levels of PSA in the blood often go up in men with prostate cancer. The PSA test is used to help find prostate cancer as well as to monitor the results of treatment.
Prostate specific antigen (PSA) is a protein produced by the cells of the prostate gland. PSA is present in small quantities in the serum of normal men, and is often elevated in the presence of prostate cancer and in other prostate disorders. A blood test to measure PSA is the most effective test currently available for the early detection of prostate cancer.
