PSA Test Facts

PSA Test

Prostate specific antigen (PSA) is a specific protein that is released by the prostate into the bloodstream. The prostate manufactures the liquid function of semen that helps transport sperm and as well provides information technology with nutrition. The PSA test measures the amount of PSA in the blood. There are normal expected levels of PSA in the claret; levels might increment in patients with prostate cancer, benign prostatic hypertrophy (a noncancerous enlargement of the prostate), and prostate infection.

Facts

• Historically, PSA has been used as a screening test for prostate cancer, but there is controversy as to whether it is an appropriate blood examination to offer male patients. The question that has been asked is whether the benefits of detecting prostate cancers are countered by the complications that might develop due to treatment of a cancer that will not ultimately bear on the patient.
• The anecdote is that all men will develop prostate cancer if they live long plenty. For that reason, in 2012, the United States Preventive Services Task Forcefulness (USPSTF) recommended against routine PSA screening for prostate cancer, referring to studies that showed that the screening did not decrease the expiry rate from the affliction. An elevated PSA test consequence may also lead to unnecessary operations including prostate biopsies (tissue samples looking for cancer) and prostatectomy (removal of the prostate). Complications of the procedures included urinary incontinence and sexual impotence.
• The American Urologic Association (AUA) has an culling stance. Urologists are the specialists who care for prostate cancer patients. They point out that prior to PSA testing, near prostate cancer was metastatic or had spread to other parts of the trunk at the time of diagnosis. After PSA screening began, prostate cancer was found much before earlier it had a run a risk to spread.
• The American Cancer Society believes that the patient and health care professional should take an informed discussion of the risks and benefits of performing a PSA screening test and come up to a shared decision.

What Is the PSA Test For?

The decision to screen a patient for prostate cancer using PSA should exist based upon the patient's individual situation, including age, past medical history, estimated life expectancy, family history of affliction, and concrete examination. The health care professional and patient should discuss the risks and benefits of the screening examination and proceed once they come to an agreement.

For patients who have had prostatectomy (prostate + ectomy = removal) as handling for cancer, serial PSA measurements may be used to screen for recurrence of the cancer. Serial PSA testing also occurs for patients who have undergone radiation therapy instead of surgery.

What Are the Risk Factors For Prostate Cancer?

There are several factors that increase the risk of developing prostate cancer:

• Age: Prostate cancer increases with age afterwards age fifty, and the bulk of cancers are diagnosed after the age of 65.
• Ethnicity: African American males are at higher risk for developing and dying from prostate cancer. Asian and Hispanic males are at a decreased risk.
• Family history: A positive family unit history increases the risk of developing prostate cancer.
• Genetics: There are some gene mutations that increase the risk of prostate cancer, including the BRCA1 and BRCA2 mutations. These are the same genes that increase the risk of breast and ovarian cancers in women.
• Diet: Diets high in blood-red meat and lower in fruits and vegetables may increase cancer risk.
• Location: Prostate cancer is found more oft in North America, the Caribbean, Australia, and parts of Western Europe, as compared to the residue of the world.

Prostate Cancer Screening Guidelines by Age

• Share Your Story

In 2013, the American Urologic Association published guidelines for the early detection of prostate cancer.

• Age less than xl: No routine screening in men younger than age 40.
• Historic period between forty and 54: No routine screening in men between the ages 40 to 54 years who are at average take a chance.
• Age between 55 and 69: "The decision to undergo PSA screening involves weighing the benefits of preventing prostate cancer mortality in i homo for every 1,000 men screened over a decade against the known potential harms associated with screening and treatment. For this reason, the Panel strongly recommends shared conclusion-making for men age 55 to 69 years that are considering PSA screening, and proceeding based on men'due south values and preferences." And screening may be preferred every 2 years instead of annually in patients involved in shared controlling.
• Age 70 and older: Routine PSA screening is not recommended in men aged lxx years or older or in whatever man with less than a 10- to xv-yr life expectancy.

• PSA examination results are typically reported every bit nanograms of PSA per milliliter (ng/mL) of claret.
• There is no specific normal or aberrant PSA level in the blood.
• In the past, a level of 4.0 ng/mL was considered as the upper limit of normal, but a patient with a normal PSA may notwithstanding have cancer, and elevated PSA levels can exist produced by a normal prostate gland.

PSA Examination Estimation and Accuracy

PSA levels may be elevated in the presence of a prostate infection (prostatitis) or considering of benign prostatic hypertrophy (BPH). However, the higher the PSA level, the more probable that prostate cancer might be nowadays. Every bit well, when serial PSA tests are washed over time, a rising PSA level is concerning for the presence of cancer.

An elevated PSA usually leads to a recommendation past the health care professional to consider farther testing. These may include an ultrasound of the prostate, cystoscopy (in which a scope is passed through the urethra in the penis to view the urethra and float), and urinalysis to wait for infection.

A biopsy of the prostate may also be considered, in which a urologist places a sparse needle into the prostate and obtains a tissue sample that is examined by a pathologist under a microscope, looking for aberrant or cancerous cells.
