Positron Emission Tomography Scan
A PET scan is similar to a bone scan, in that a slightly radioactive substance is injected into the blood, which can then be detected with a special camera. But PET scans use different tracers that collect mainly in cancer cells. The most common tracer for standard PET scans is FDG, which is a type of sugar. Unfortunately, this type of PET scan isnt very useful in finding prostate cancer cells in the body.
However, newer tracers, such as fluciclovine F18, sodium fluoride F18, and choline C11, have been found to be better at detecting prostate cancer cells.
Other newer tracers, such as Ga 68 PSMA-11 and 18F-DCFPyl , attach to prostate-specific membrane antigen , a protein that is often found in large amounts on prostate cancer cells. Tests using these types of tracers are sometimes referred to as PSMA PET scans.
These newer types of PET scans are most often used if its not clear if prostate cancer has spread. For example, one of these tests might be done if the results of a bone scan arent clear, or if a man has a rising PSA level after initial treatment but its not clear where the cancer is in the body.
The pictures from a PET scan arent as detailed as MRI or CT scan images, but they can often show areas of cancer anywhere in the body. Some machines can do a PET scan and either an MRI or a CT scan at the same time, which can give more detail about areas that show up on the PET scan.
Prostate Cancer Screening Ages 40 To 54
The PSA test is a blood test that measures how much of a particular protein is in your blood. Its been the standardfor prostate cancer screening for 30 years.
Your doctor will consider many factors before suggesting when to startprostate cancer screening. But hell probably start by recommending the PSAtest.
While the general guidelines recommend starting at age 55, you may need PSAscreening between the ages of 40 and 54 if you:
- Have at least one first-degree relative who has had prostate cancer
- Have at least two extended family members who have had prostate cancer
- Are African-American, an ethnicity that has a higher risk of developing more aggressive cancers

Who Should Be Screened And When
A variety of factors determine when and who should be screened. Prostate screening is considered for men ages 55 to 69 but can be continued above age 70 in healthy men. Screening for prostate cancer may be considered for men between the ages of 40 and 54 in those at higher risk for cancer , says Dr. Christiansen. Men outside the age range of 55 to 69 may still need to undergo prostate-specific antigen blood testing or a prostate exam to assist with the diagnosis and management of benign prostatic hyperplasia or other urologic conditions. The American Urologic Association guidelines do not recommend routine screening in men between ages 40 to 54 years who are at average risk. For men younger than age 55 at higher risk, prostate cancer screening decisions should be individualized. A routine screening interval of two years or more may be preferred over annual screening in those men who have participated in shared decision making with their doctor.
How Do I Screen For Prostate Cancer
There are two main early stage screening methods a digital rectal exam , and a blood test measuring PSA levels. PSA screening is regarded as the best method to screen for prostate cancer in men over 40 or those of a certain risk factor.
While men might be intimidated by a DRE, itâs a quick and safe screening technique used by a physician, and should cause no significant pain.
A Digital Rectal Exam is a simple, painless and quick procedure. A physician inserts a gloved and lubricated finger into the rectum and feels the prostate to identify if the prostate is enlarged, has lumps or is an abnormal texture compared to a healthy example.
Although this procedure is a very clear indicator of prostate health, the entire prostate canât be examined during a DRE. This is why physicians will also take into account PSA blood work, health history, and other risk factors. Overall, itâs often difficult to detect prostate cancer early, itâs mostly found through PSA testing – so PSA screenings should be done regularly, starting at the age of 40-50.
What Is A Prostate Cancer Screening Like
A prostate cancer screening can be conducted in one of two ways. The first, a PSA test, is a simple blood draw. The second is a brief rectal exam that takes less than 30 seconds to perform.
“For a screening, if a patient comes and asks for a prostate cancer screening, it begins with a blood test,” said Ehdaie. “It’s a small vial of blood, and then a medical history and physical examination. In the physical examination there will be a digital rectal examination in which the physician’s finger is inserted into the rectum to feel the prostate.”

Rettig said that someone who has a “strong family history” of early onset prostate cancer might want to talk to their primary care provider or other health care practitioner earlier in life, while someone with less risk might prefer to wait.
The guidelines for how often men should be screened again also vary. If you have a high prostate-specific antigen , a protein made by cells in the prostate gland, you may be recommended to come back for more frequent screenings, but those with lower PSA levels might only be advised to come back every four years or so.
“If you’re 55 and have you have a PSA of less than one, you can wait four years to get screened again,” Rettig explained. “Alternatively, if you’re 45 and have a PSA of two and a half, that might be someone who might get a biopsy or be re-screened within the year. … How frequently one would be prescreened is really contingent upon the specifics of the patient.”
What Are The Prostate Cancer Symptoms I Need To Look Out For
In its early stages, prostate cancer may not show any symptoms. Symptoms of early prostate cancer can include:
- difficulty passing urine
- a slow, interrupted flow of urine
- frequent passing of urine, including at night
Symptoms associated with advanced prostate cancer include:
- blood in urine
- pain during urination
- lower back or pelvic pain.
These symptoms are also found in men who may have benign prostatic hyperplasia , a common, non-cancerous enlargement of the prostate gland.
If you experience these symptoms, visit your doctor.

Early Cancer Detection Can Save Lives And Cut Treatment Costs But When Should You Start Having Prostate Exams And Do You Need To Have Them At All
When it comes to screening for prostate cancer, some men may be confused or apprehensive about beginning to get annual exams.
As prostate cancer affects one out of every six men, the American Cancer Society and other leading medical organizations recommend older men discuss having annual prostate cancer screenings with their primary care doctor to help detect the disease early. Early detection of the disease helps cure it in 90 percent of cases.
Generally, it is recommended that men with an average risk of prostate cancer start being screened with a digital rectal exam and PSA blood-level exam when they hit the age of 50. African-American men and men who have a father, brother or son who were diagnosed with prostate cancer when they were younger than 65 are at higher risk and should start screenings at age 40. Men who have had more than one of these close relatives diagnosed before age 65 are at even higher risk.
Preparing For Prostate Examinations
Due to the personal nature of a prostate examination, its normal to feel a bit anxious but it will be easier if you relax and practise some deep breathing.
Recent ejaculation can affect your PSA level, so your doctor might ask you to abstain from sexual activity for a period of time before your examination.

Who Should Get A Prostate Exam
Starting at age 50, all men should discuss prostate cancer screening with their doctor. The American Cancer Society advises men at higher risk to have this conversation at age 45.
Youre considered to have an increased risk if youre African-American or if a first-degree relative had prostate cancer before age 65. If more than one first-degree relative had prostate cancer before age 65, you might want to consider beginning prostate cancer screening even earlier.
The ACS estimates there will be about 26,120 men will die from it.
Prostate cancer is easier to treat before it spreads. However, some prostate cancers are so slow-growing that they dont always require treatment. A lot depends on your age and other factors.
Discuss your risk factors with your doctor, and ask if you should have a prostate exam as part of your yearly checkup.
Before Having A Rectal Examination
Your doctor or nurse should explain what’s going to happen and why you need a rectal examination.
They’ll know that some people can feel embarrassed, but it’s a common procedure.
Let the doctor or nurse know if:
- you’d prefer a man or woman to perform the examination
- you’d like someone else in the room it could be a friend, family member or another doctor or nurse
- you have severe pain in your bottom they may be able to use local anaesthetic to numb the area

What Are Additional Tests For Detecting Prostate Problems
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 or computerized tomography scan.

When To Get A Prostate Cancer Screening
A prostate screening can help your doctor find prostate cancer early, but youll need to decide if the benefits of the exam outweigh the risks. Have a discussion with your doctor about prostate cancer screenings.
The U.S. Preventive Services Task Force now recommends that men ages 55 to 69 decide for themselves whether to undergo a prostate-specific antigen screening test, after talking it over with their doctor.
They recommend against screening for men at or above the age of 70.
The American Cancer Society strongly recommends that no one be screened without discussion of the uncertainties, risks, and potential benefits of prostate cancer screening.
They give these specific recommendations for the date at which these discussions with a healthcare provider should take place:
- Age 50 for men who are at average risk of prostate cancer and are expected to live at least 10 more years.
- Age 45 for men at high risk of developing prostate cancer. This includes African Americans and men who have a first-degree relative diagnosed with prostate cancer at an early age .
- Age 40 for men at even higher risk .
You should also speak with your doctor about a prostate exam if youre experiencing symptoms of a prostate problem, such as frequent or painful urination or blood in your urine.
After this discussion, if you decide to get a prostate cancer screening, the ACS and the American Urologic Association recommend getting a prostate-specific antigen blood test.

Specialist Referral And Biopsy
Your doctor will discuss your prostate check results with you. If the PSA and DRC results suggest you have a high risk for prostate cancer, your doctor will refer you to a urologist .
The specialist will discuss having a prostate biopsy, in which a small sample of your prostate gland cells are taken for examination.
The aim of the biopsy is to confirm whether or not you have prostate cancer and, if so, whether it needs treatment. The treatment options will then be discussed with you.
If the biopsy shows no evidence of cancer, you may be advised to attend future check-ups.
What Happens During A Digital Rectal Exam
Your health care provider will insert a gloved finger into the rectum and feel the prostate for hard, lumpy, or abnormal areas. The test takes only a few minutes to complete.
You may feel slight, momentary discomfort during the test. The procedure does not cause significant pain or any damage to the prostate.

First What Is Prostate Cancer
Prostate cancer is cancer that occurs in the prostate â a small walnut-shaped gland in men. This is the gland that produces the seminal fluid that nourishes and transports sperm. Prostate cancer is one of the most common cancers in men. Thankfully some prostate cancers are slow growing, without causing serious harm. However, others are aggressive, so for both scenarios, identifying the cancer earlier is key.
How Is Prostate Cancer Detected
There is no single test to detect prostate cancer. The two most common tests are the prostate specific antigen blood test and the digital rectal examination .
The PSA test measures the level of PSA in your blood. It does not specifically test for cancer. Virtually all PSA is produced by the prostate gland. The normal range depends on your age. A PSA above the typical range may indicate the possibility of prostate cancer. However, two-thirds of cases of elevated PSA are due to noncancerous conditions such as prostatitis and BPH.
A DRE is generally conducted by a urologist to feel the prostate. While DRE is no longer recommended as a routine test for men who do not have symptoms of prostate cancer, it may be used to check for any changes in the prostate before doing a biopsy.
If either of these tests suggest an abnormality, other tests are necessary to confirm a diagnosis of prostate cancer, usually a magnetic resonance imaging scan and transrectal ultrasound biopsy.

If your DRE or PSA test shows an abnormal result, your doctor may suggest that you do other tests to confirm whether or not you have prostate cancer. It may be recommended that you do an ultrasound and/or a prostate biopsy.
The ultrasound will collect images of your prostate. These images will then be assessed for abnormalities consistent with prostate cancer. The prostate biopsy involves the collection of prostate tissue which is analysed for cancer cells.

The Initial Causes How Often Should A Man Get A Prostate Exam
One of the first symptoms of prostate issues is pain or tenderness in the groin or lower back. This can be the result of a noncancerous condition called enlarged prostatic tissue, or it could be an infection of the bladder. In either case, its important to see a doctor as soon as possible. If youre suffering from prostate pain, you may want to consider reducing your caffeine intake.
Another symptom of a potentially enlarged prostate is difficulty starting a stream of urine, leaking, or dribbling. These symptoms are not serious, but theyre still alarming. Most men put up with an enlarged prostate for years before seeking medical attention, but they typically seek treatment as soon as they notice symptoms. Even if you dont have symptoms, its worth getting checked to determine if you have any prostate issues.
If you experience nightly bathroom runs, you may be experiencing an enlarged prostate. You may be having difficulty starting a stream of urine, or you may even be dribbling or leaking during the day. These problems arent life-threatening, but can become a nuisance. You should not ignore these signs and seek treatment as soon as you notice them. If you feel any of these symptoms, you should consult a doctor.

What To Expect During The Digital Rectal Exam
This examination can be done while you are either standing or lying down. This may depend on the examination room and any other health conditions that you have.
If standing, you will be asked to stand facing the examination bed, with feet apart, body bent forward, and your arms or elbows on the bed. Feel free to ask your healthcare provider to give you a heads up before each part of your exam.
Your healthcare provider will coat their gloved finger in lubricant. They will insert their finger into your rectum at a downwards angle. You may feel a little pressure or slight discomfort, but it shouldn’t hurt. It is important to relax and take deep breaths and let your healthcare provider know immediately if you feel any pain.
It may take a few seconds for your external sphincter muscle to relax, and your provider may ask you to bear down as if you are having a bowel movement. They will move their finger in a circular motion in order to identify the lobes of your prostate gland.
A normal prostate is usually around 2-4 cm long and has a triangular shape, with a firm and rubbery texture.
During this exam, the healthcare provider checks for:
