Meaning Of PSA Test Numbers Results: Prostate Cancer Screening

Meaning Of PSA Test Numbers Results: Prostate Cancer Screening . A PSA test number is result of a PSA test. It indicates the level of prostate specific antigen (PSA) in the body. This antigen is a type of protein secreted by the prostate gland, and could mostly be found in the semen. Blood prostate specific antigen (PSA) is the most sensitive test for early detection of the prostatic cancer. Doctors advise a PSA test from their male patients if prostate enlargement or benign inflammation of the prostate is detected.

PSA Test Numbers Meaning

Patients who have undergone PSA tests must be aware that high levels of PSA indicate high risks for prostate cancer.

Here is a brief description of the PSA test numbers range:

• If the PSA test result shows that the patient has less than 4 nanograms per milliliter of antigens in his blood, his PSA level is normal.
• If the antigens amount to as much as 4 – 10 nanograms per milliliter, he is at risk of having cancer by 30%.
• If the patient’s PSA level indicates 10 – 20 nanograms per milliliter, there is a 50 to 75% chance that he may develop prostate cancer.
• If the PSA test result reveals that he has 20 nanograms per milliliter of PSA in his blood, he is at 90 % risk for cancer.

Prostate Cancer Screening Test

Patients must take note that the PSA test does not entirely indicate prostate cancer. This test is just one among the many others that a patient must undergo so that accurate prognosis may be made. The PSA test just calculates the risk for prostate cancer occurrence in patients. In a patient with known prostate carcinoma PSA levels are useful in assessing the response to the therapy and detecting early response.

The PSA Test is an important indication or gauge for prostate cancer patients. The patient undergoes this test a number of times for a certain period in order to monitor the strength and severity of the cancer and to determine if the treatment used is effective.

PSA is not a perfect tumor marker due lack of specificity, elevated levels may be seen in benign prostate enlargement. Approximately 1/3 of it can be false negative, so it cannot be a cent percent sensitive test. Combined use of PSA and digital rectal examination allows detection of about two third cases of prostatic carcinoma in early stage.

F77 for Prostate Health Diagnosis

• U.S. researchers have discovered an antibody called F77, which tracks down prostate cancer cells and kills them, even in advanced stages of the disease.
• Research has demonstrated that the antibody bonds more easily with the malignant cells, than with benign cells. It also encourages the death of the cancerous cells.
• Clinical trials have been carried out on mice. The results showed that the F77 antibody bonded well with malignant prostate cancer cells and tissues. Additionally, F77 instigated direct cell death of the cancerous cells and tissues.
• But, this antibody did not target other cancer cells like kidney, colon, cervix, bladder, pancreas, or skin.
• F77 is a promising and powerful tool, to diagnose and treat prostate cancer, especially, androgen independent metastatic cancers which are relatively difficult to treat.
