The most effective means of detecting prostate cancer early is through a screening, which involves a digital rectal exam and measuring the amount of prostate-specific antigen PSA in the blood. In a digital rectal exam, the doctor inserts a gloved, lubricated finger into the anus in order to feel the shape and size of the prostate. The PSA test is believed to find most prostate cancers. PSA is a protein that the prostate secretes into the bloodstream. If a man has higher levels of this antigen, it may mean he has prostate cancer.
PIN is often divided into 2 groups:. The needle is then used to remove a few pieces of prostate tissue for examination with a microscope. The health care provider will also ask the patient. What are additional tests for detecting prostate problems? Moris L, et al. A scanner then detects this substance to produce images of the inside of the body. Older men are at risk for prostate cajcer as well, but it is much less common than BPH.

Knowing that waiting for answers can add to your anxiety, we offer reduce wait times for appointments, while working to deliver results in an expedited manner. Our multidisciplinary team of doctors and clinicians will then use what they learn to evaluate the type , stage and extent of the disease, so we can develop a treatment plan personalized to your needs, goals and preferences. The types of tests you may undergo to diagnose prostate cancer include those listed below.
During a prostate cancer biopsy , your doctor guides a small probe into the rectum and removes a small tissue sample from the prostate for further examination.
This tissue allows the doctor to stage the disease and determine an appropriate treatment plan. A digital rectal exam is usually the first step in determining prostate health, and is often performed as part of routine screening, such as an annual physical.
Bone scan: Prostate cancer may metastasize to the bones. If you are experiencing bone pain or blood tests reveal elevated calcium levels, your radiation oncologist may perform a bone scan to detect if prostate cancer has spread to the bones.
CT scan : A CT scan reveals blood flow and anatomy of tissues in and around the prostate, allowing for the diagnosis and monitoring of tumor growth. This is important to catch the disease early. ProstaScint scan: This technology may be used to determine whether prostate cancer has spread to the lymph nodes, adjacent tissues or bones.
Ultrasound : This technology may be used to monitor prostate size, tumor response or activity in other tissues. In detecting prostate cancer, your doctor may also recommend a transrectal ultrasound. During this exam, a small probe is inserted into the rectum so sound waves may provide a picture of the prostate and measure its size.
Images will reveal tumors, calcifications and enlargement of the prostate. Prostate specific antigen PSA is a protein found in prostate cells that helps to keep semen liquified.
Most cases of prostate cancer develop in these cells, so an elevated PSA count may be a sign of prostate cancer. Doctors may set a baseline PSA level lower for men with higher risk, such as African Americans and those with a family history of prostate cancer. Not all men with high PSA levels have prostate cancer. High levels may also be caused by a urinary tract infection, prostatitis or benign prostatic hyperplasia, all of which are noncancerous conditions.
Men with a low PSA level may still develop prostate cancer. PSA tests are not an indication of how aggressive the prostate cancer may be.
Many prostate cancers are slow growing and do not require immediate treatment. PSA can be measured with a blood test that often is performed along with a digital rectal exam DRE , which allows your doctor to feel the prostate for abnormalities in shape, size and texture. According to the ACS, healthy men with a low or average risk of developing prostate cancer should talk to their doctor about screening at the age of Men with a higher risk should talk to their doctor about screening at 40 or National Comprehensive Cancer Network suggests theses screening guidelines and recommendations for men older than Learn more about the symptoms of prostate cancer.

Similarly, those who had a barium enema at least 10 years prior to diagnosis were about two and half times more likely to have prostate cancer as compared to those not exposed to barium enemas. Occup Environ Med. The actual diagnosis of prostate cancer can only be made with a prostate biopsy discussed below. Studies in the past have looked at the association between occupational exposure to radiation and an increased risk of prostate cancer and provided conflicting evidence Beral et al , ; Atkinson et al , For those with a family history of cancer, exposures to hip x-rays dating 10 or 20 years before diagnosis were associated with a significantly increased risk of prostate cancer: adjusted OR 5.

Prostate Cancer: Diagnosis | irepliquedemontres.com
The prostate is a walnut-shaped gland that is part of the male reproductive system. It has two or more lobes, or sections, enclosed by an outer layer of tissue.
The prostate is located in front of the rectum and just below the bladder, where urine is stored. It surrounds the urethra at the neck of the bladder and supplies fluid that goes into semen. The most common prostate problem in men younger than age 50 is inflammation, called prostatitis. Prostate enlargement, or benign prostatic hyperplasia BPH , is another common problem. Because the prostate continues to grow as a man ages, BPH is the most common prostate problem for men older than age Older men are at risk for prostate cancer as well, but it is much less common than BPH.
Different prostate problems may have similar symptoms. For example, one man with prostatitis and another with BPH may both experience urinary urgency. Sometimes symptoms for the same prostate problem differ among individuals.
For example, one man with BPH may have trouble beginning a urine stream, while another may experience nocturia. A man in the early stages of prostate cancer may have no symptoms at all. Because of this confusing array of symptoms, a thorough medical exam and testing are vital.
To diagnose prostate problems, the health care provider will perform a digital rectal exam DRE. The health care provider will also ask the patient. Answers to these questions will help the health care provider identify the problem or determine what medical tests are needed.
Diagnosing BPH may require a series of medical exams and tests. A DRE is a physical exam of the prostate. The health care provider will ask the patient to bend over a table or lie on his side while holding his knees close to his chest.
The health care provider slides a gloved, lubricated finger into the rectum and feels the part of the prostate that lies next to it. The DRE may be slightly uncomfortable, but it is brief. This exam reveals whether the prostate has any abnormalities that require more testing. If an infection is suspected, the health care provider might massage the prostate during the DRE to obtain fluid to examine with a microscope.
This exam is usually done first. Many health care providers perform a DRE as part of a routine physical exam for men age 50 or older, some even at age 40, whether or not the man has urinary problems. The first test for detecting prostate problems is a blood test to measure prostate-specific antigen PSA , a protein made only by the prostate gland. This test is often included in routine physical exams for men older than age Because African American men have higher rates of getting, and dying from, prostate cancer than men of other racial or ethnic groups in the United States, medical organizations recommend a PSA blood test be given starting at age 40 for African American men.
Medical organizations also recommend a PSA blood test be given starting at age 40 for men with a family history of prostate cancer. Some medical organizations even recommend a PSA blood test be given to all men starting at age If urination problems are present or if a PSA blood test indicates a problem, additional tests may be ordered. These tests may require a patient to change his diet or fluid intake or to stop taking medications. If the tests involve inserting instruments into the urethra or rectum, antibiotics may be given before and after the test to prevent infection.
A PSA blood test is performed to detect or rule out prostate cancer. The amount of PSA in the blood is often higher in men who have prostate cancer. However, an elevated PSA level does not necessarily indicate prostate cancer. The U. Food and Drug Administration has approved the PSA blood test for use in conjunction with a DRE to help detect prostate cancer in men age 50 or older and for monitoring men with prostate cancer after treatment. However, much remains unknown about how to interpret a PSA blood test, its ability to discriminate between cancer and problems such as BPH and prostatitis, and the best course of action if the PSA level is high.
However, the test is known to have relatively high false-positive rates. A PSA blood test also may identify a greater number of medically insignificant lumps or growths, called tumors, in the prostate. Health care providers and patients should weigh the benefits of PSA blood testing against the risks of follow-up diagnostic tests. The procedures used to diagnose prostate cancer may cause significant side effects, including bleeding and infection. If the DRE or the PSA blood test indicates a problem may exist, the health care provider may order additional tests, including urinalysis, urodynamic tests, cystoscopy, abdominal ultrasound, transrectal ultrasound with prostate biopsy, and imaging studies such as magnetic resonance imaging MRI or computerized tomography CT scan.
Urinalysis is the testing of a urine sample for abnormal substances or signs of infection. If an infection is suspected, the health care provider may ask that the urine sample be collected in two or three containers during a single urination to help locate the infection site.
After the first collection, the health care provider will have the patient stop the urine stream for a prostate massage before collecting more urine. If signs of infection appear in the first container but not in the others, the infection is likely to be in the urethra. If the urine contains significantly more bacteria after the prostate massage or bacteria are in the prostate fluid itself, the infection is likely to be in the prostate.
Urodynamic testing is any procedure that looks at how well the bladder, sphincters, and urethra are storing and releasing urine. If the prostate problem appears to be related to urine blockage, the health care provider may recommend tests that measure bladder pressure and urine flow rate.
One test involves urinating into a special device that measures how quickly the urine is flowing and records how many seconds it takes for the peak flow rate to be reached. Another test measures postvoid residual, the amount of urine left in the bladder when urination stops. A weak urine stream and urinary retention may be signs of urine blockage caused by an enlarged prostate that is squeezing the urethra.
Cystoscopy is a procedure that allows the health care provider to look for blockage in the lower urinary tract. A cystoscope is a tubelike instrument used to look inside the urethra and bladder. After a solution numbs the inside of the penis, the health care provider inserts the cystoscope through the opening at the tip of the penis and into the lower urinary tract.
By looking through the cystoscope, the health care provider can determine the location and degree of the urine blockage. The procedure is usually performed by a urologist, a doctor who specializes in treating problems of the urinary tract and the male reproductive system. Ultrasound uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure.
The transducer can be moved to different angles to make it possible to examine different organs. The gel allows the transducer to glide easily, and it improves the transmission of the signals. Anesthesia is not needed. An abdominal ultrasound can create images of the entire urinary tract. The images can show damage or abnormalities in the urinary tract resulting from urine blockage at the prostate. Transrectal ultrasound is most often used to examine the prostate.
The ultrasound image shows the size of the prostate and any abnormal-looking areas, such as tumors. Transrectal ultrasound cannot definitively identify prostate cancer. To determine whether a tumor is cancerous, the health care provider uses the transducer and ultrasound images to guide a needle to the tumor. The needle is then used to remove a few pieces of prostate tissue for examination with a microscope. This process, called biopsy, can reveal whether prostate cancer is present.
The biopsied prostate tissue is examined in a laboratory by a pathologist—a doctor who specializes in diagnosing diseases. The MRI machines use radio waves and magnets to produce detailed pictures.
An MRI may also involve the injection of dye. A CT scan uses a combination of x-rays and computer technology to create three-dimensional 3-D images. A CT scan may also involve the injection of a dye.
MRI and CT scan images can help identify abnormal structures in the urinary tract, but they cannot distinguish between cancerous tumors and noncancerous prostate enlargement.
Once a biopsy has confirmed cancer, these imaging techniques will show how far the cancer has spread.
MRIs and CT scans are usually performed at an outpatient center or hospital by a specially trained technician and interpreted by a radiologist; anesthesia is not needed. For an MRI, light sedation may be used for people with a fear of confined spaces. Urodynamic tests and cystoscopy may cause mild discomfort for a few hours after the procedures. Drinking an 8-ounce glass of water every half-hour for 2 hours may help reduce discomfort. The health care provider may recommend taking a warm bath or holding a warm, damp washcloth over the urethral opening to relieve discomfort.
A prostate biopsy may produce pain in the area of the rectum and the perineum, which is between the rectum and the scrotum. A prostate biopsy may also produce blood in urine and semen. Results for simple medical tests such as some urodynamic tests, cystoscopy, and abdominal ultrasound are often available soon after the test. The results of other medical tests such as PSA blood test and prostate tissue biopsy may take several days to come back.
A health care provider will talk with the patient about the results and possible treatments for the problem. Eating, diet, and nutrition have not been shown to play a role in causing or preventing prostate problems. Clinical trials are part of clinical research and at the heart of all medical advances. Clinical trials look at new ways to prevent, detect, or treat disease. Researchers also use clinical trials to look at other aspects of care, such as improving the quality of life for people with chronic illnesses.
