A screening test to detect prostate cancer that measures protein levels is called?
The prostate-specific antigen (PSA) test is a blood screen for prostate cancer.
What happens to acid phosphatase levels when prostate cancer spreads to other parts of the body?
acid phosphatase levels rise, particularly if the cancer spreads to the bone. One-half to three-fourths of persons who have metastasized prostate cancer have high acid phosphatase levels
How does estrogen effect the prostate?
As a general term "cancer" means that some abnormal cells are present in a particular part of your body. All the cells of our body have their own "program" to live, but cancer cells do not follow this program. The same happens with prostate cancer, it is characterized by the presence of abnormal prostate cells (cancer cells), causing the damages to prostate and other symptoms. These cells are capable to multiply very fast, increasing their number and the tumor size. Because of this, the normal prostate cells are suppressed and cannot function properly. When a man has prostate cancer, his PSA (prostate specific antigen) levels will rise. In many cases of prostate cancer, the prostate gland is removed.
What do higher than normal PSA levels mean?
Elevated PSA levels can mean different things. It can point to a higher risk of cancer of the prostate or it could point to a more benign enlargement of the prostate. It is important to understand that prostate cancer can occur with normal PSA levels present. Your boyfriend should follow up with his physician to do more tests to determine what is causing the elevated PSA levels.
Having Low blood selenium levels correlate with what illness?
prostate cancer
What is the function of a PSA?
Blood tests are used to measure the amounts of certain protein markers, such as prostate-specific antigen (PSA), found circulating in the blood.
What hormone elevated when a patient has prostate cancer?
The biologic marker that is elevated is called the PSA (prostatic specific antigen), but this is not a hormone. However, in prostate cancer, it is desirable to lower the levels of a hormone group called androgens (including testosterone, among others).
What is PSA score range?
PSA or Prostate-specific antigen is a test that measures the blood level of the PSA which is a protein in the prostate gland. There is no specific normal range. In the past the normal range has been 4.0 ng/mL and lower. Since than doctors have noted patients with levels of 4.0 and below to have cancer while patients with high levels did not.
Do woman get prostate cancer?
Women do not classically get prostate cancer as cancer of the prostate is classified as a disease of the prostate gland of the male reproductive system. However, in 2002 the female Skene's Gland was officially renamed the female prostate as it was found to be homologous in function. Both male and female prostates produce Prostate Specific Antigen (PSA) and contribute to the ejaculate fluid. Six cases of adenocarcinoma have been observed as originated from the female prostate that strongly resemble that of classical male prostate cancer. Serum tests showed elevated levels of PSA, typical in prostate cancer.
Some liver cancer patients show high levels of what protein?
Between 50% and 75% of primary liver cancer patients have abnormally high blood serum levels of a particular protein (alpha-fetoprotein or AFP).
Why Normal PSA Levels In The Blood Can Change?
The prostate-specific antigen (PSA) is a protein that is produced by the prostate gland. It is generated naturally in a small amount in healthy men. The protein is thought to be an essential part of human reproduction and serves several purposes. A normal PSA level in a healthy adult male is 4 nanograms per millimeter of blood. Normal PSA levels can change for a number of different reasons. The concentration of PSA in the blood has been found to rise when an individual has medical problems that affect the prostate. Specifically, prostate cancer can sometimes be detected by testing for PSA levels in the blood. Individuals who do have a higher than normal PSA level are usually scheduled to receive one or more additional tests that can include a rectal sonogram or a biopsy of the gland. These tests are intended to locate more conclusive signs of potential prostate cancer including the detection of cancerous cells in a biopsy. Normal PSA levels in men can become elevated for a number of reasons other than the presence of a medical condition or cancer. Conditions that affect other areas of the body can elevate levels artificially. One example is a liver inflammation that results from hepatitis. The size of the prostate can also result in higher PSA levels in the blood. Older men or men who have an enlarged prostate that is not related to a disease can show elevated levels despite having no related medical condition. The amount of PSA in the blood can be reduced by factors like diet or medication. This has resulted in some medical professionals who do not believe that PSA testing should be performed on healthy individuals because of the high number of false positives that can occur. A more accurate form of testing for normal PSA levels can be done by compiling the results of the tests over time. Temporary increases or reductions in the concentration of the protein can be disregarded if PSA levels remain relatively stable in previous tests. A good indication that an individual has prostate cancer is if PSA levels steadily increase every few months for a year or more. Individuals who have a PSA level of over 20 nanograms per millimeter of blood are normally checked for prostate cancer regardless of previous trends.
Normal PSA Levels?
In men over 40 years of age, is common for doctors performing blood tests on their patients to examine Prostatic Specific Antigen (PSA) levels. PSA is a protein produced by the male prostate gland. If the PSA level is above certain levels, or has shown to be getting progressively higher over a number of tests conducted over a period of time, it serves as a warning sign of either prostate cancer or other noncancerous prostatic diseases. A normal PSA level does not completely rule out the possibility of prostate cancer. Many doctors are of the opinion that any male who lives long enough will eventually develop prostate cancer, but that it may not necessarily be the cause of death. Given the somewhat vague nature of the results supplied by PSA testing, it is also necessary to consider adding a colonoscopy to the equation along with occasional digital prostate exams. The PSA test, however, is a popular diagnostic tool, since it is noninvasive in nature. Knowing normal PSA levels will assist a personal care physician in determining a patient's prostate cancer risk when other factors, such as family history are included. A PSA level of below four ng/ml (nanogram/milliliter) is often used as the basis to eliminate concern about the risk of prostate cancer, even though this level does not completely eliminate the possibility. A PSA level below four combined with a digital examination that indicates normal prostate size means that there is only a 15% chance of prostate cancer being present. This increases to 25% for PSA levels between four and 10. Anything above 10 represents an increase to 67%. Some experts in the area of PSA levels promote using lower numbers, less than 2.5 or 3.0 ng/ml to represent normal values. This is particularly applicable to younger patients who have not experienced the normal prostate gland the enlargement that accompanies advancing age. Equally important to the PSA number is the trend of that number. Is it going up, how quickly, over what period of time? These are questions doctors will consider on a patient by patient basis?
