How Do I Prepare For A Prostate Ultrasound

Prostate Cancer Staging Using CT Scans

You dont need to do much to prepare for a prostate ultrasound. Its an outpatient procedure that usually takes less than an hour. Your doctor may refer you to a hospital or clinic that has the proper ultrasound equipment for this test. You may also need to sign a consent form before the test.

Some possible instructions that your doctor might give you before the test include:

  • Dont eat for a few hours before the test.
  • Take a laxative or enema to help clear out your intestines a few hours before the test.
  • Stop taking any medications that can thin your blood, such as nonsteroidal anti-inflammatory drugs or aspirin, about a week before the procedure. This is usually recommended if your doctor plans to take a biopsy of your prostate.
  • Dont wear any jewelry or tight clothes to the clinic on the day of the procedure.
  • Take any medications recommended to help you relax during the procedure. Your doctor may recommend a sedative, such as lorazepam .
  • Make sure someones available to take you home in case your doctor gives you a sedative.

What Are The Advantages And Disadvantages Of Having An Mri Scan Before A Biopsy

Advantages

  • It can give your doctor information about whether there is cancer inside your prostate, and how quickly any cancer is likely to grow.
  • Its less likely than a biopsy to pick up a slow-growing cancer that probably wouldnt cause any problems in your lifetime.
  • It can help your doctor decide if you need a biopsy if theres nothing unusual on the scans, this means youre unlikely to have prostate cancer that needs to be treated. You may be able to avoid having a biopsy, and its possible side effects.
  • If you do need a biopsy, your doctor can use the scan images to decide which parts of the prostate to take samples from.
  • If your biopsy finds cancer, you probably wont need another scan to check if it has spread, as the doctor can get this information from your first MRI scan.;This means you can start talking about suitable treatments as soon as you get your biopsy results.

Disadvantages

  • Being in the MRI machine can be unpleasant if you dont like closed or small spaces.
  • Some men are given an injection of dye during the scan this can sometimes cause mild side effects.

Symptoms Of Benign Prostate Enlargement

The symptoms of benign prostate enlargement are caused by the enlarged prostate placing pressure on the bladder and urethra .

This can affect urination in a number of ways. For example, it can:

  • make it difficult for you to start urinating
  • weaken the;flow of urine or cause “stopping and starting”
  • cause you to strain to pass urine
  • cause you to need to urinate;frequently
  • cause you to wake up frequently during the night to urinate
  • cause a sudden urge to urinate, which can result in;urinary incontinence if you can’t find a toilet quickly enough
  • cause you to not be able to empty your bladder fully
  • cause blood in the urine

In the later stages, benign prostate enlargement can cause urine retention and other complications such as;bladder stones,;bladder infections and kidney damage.

A Negative Ct Scan For Prostate Cancer Isnt Anything To Get Too Hopeful About Because A Ct Scan Can Actually Miss Prostate Cancer

Yes, a CT scan can miss prostate cancer, says Jonathan W. Simons, MD, President and Chief Executive Officer of the Prostate Cancer Foundation, David H. Koch Chair.

Dr. Simons explains, A CT scan is fundamentally a three-dimensional X-ray of the body. It does not intrinsically distinguish between cancer and normal tissue.

We therefore rely on anatomical changes to tell us the probability something is normal or is cancer.

For example, if a lymph node is normal in size it still has the potential to have cancer in it.

However, if a lymph node is enlarged it has a much higher probability there is cancer present, although not guaranteed.

Any imaging modality cant identify microscopic disease, so a CT scan, MRI scan and PET scan can miss prostate cancer that may have spread.

The presence of prostate cancer can be indicated by an abnormally elevated PSA blood test result or by a digital rectal exam .

These tests do not diagnose a malignancy; they can only raise suspicion. Diagnosis is made only via a biopsy of tissue extracted from the prostate gland.

The MRI scan can help find a cancer of the prostate gland, especially if you have elevated or rising PSA.

If a cancer has already been found, the MRI images can show whether it has spread outside the prostate gland or not. This can have a very important impact on whether or not you have treatment, and if so, which type of treatment you receive.

Imaging Tests For Prostate Cancer

Below are imaging tests that may be used to determine the type, stage and progression of a patients prostate cancer.

Bone scan: Prostate cancer may metastasize to the bones. If a patient is experiencing bone pain, or blood tests reveal elevated calcium levels, a oncologist may perform a bone scan to determine whether the prostate cancer has spread to the bones. During a bone scan, a doctor injects a small amount of low-level radioactive material that shows up in affected regions of bone when images are taken, pinpointing where the cancer is located.

Computed tomography scan: A CT scan reveals blood flow and anatomy of tissues in and around the prostate, allowing for a diagnosis and the monitoring of tumor growth.

Magnetic resonance imaging : An MRI may be especially useful for the prostate, due to greater soft tissue contrast. MRIs may help determine whether a biopsy is needed, improve the accuracy of biopsies, and detect cancer spread.

Positron emission tomography/computed tomography scan: A PET /CT scan is an advanced nuclear imaging technique that combines CT scan technology with positron emission tomography into one machine. A PET/CT scan shows both the structure and function of cells and tissues in the body during a single imaging session. In the case of prostate cancer, this scan provides a more comprehensive view of the pelvis to determine the presence of abnormal activity, even before a tumor may have developed.

Prostate Biopsy The Standard Screening Option But Not Without Flaws

During a prostate biopsy, a thin needle is inserted through the wall of your rectum and into the prostate to collect a sample of tissue. This may be repeated up to 12 times to take 12 separate samples. Most doctors will use a local anesthetic to numb the area, and blood may persist in the urine or semen for a few weeks after the biopsy. If the areas the doctor collected did not have cancer, a follow up biopsy might be performed.

A prostate biopsy can occasionally cause bleeding, pain and infection. And it can lead to the diagnosis of clinically insignificant cancers that would never have been detected or caused any problems for the patients.

Advanced Genomic Testing For Prostate Cancer

The most common lab test;for prostate cancer is advanced genomic testing, which examines a tumor to look for DNA alterations that may be driving the growth of the cancer. By identifying the mutations that occur in a cancer cells genome, doctors may get a clearer picture of the tumors behavior and be able to tailor a patients treatment based on the findings.

What Happens Before The Cat Scan

If a dye is required for your CAT scan, you may be instructed to have a blood test first. The purpose of the blood test is to make sure your kidneys will be able to get rid of the dye. Not getting this blood test may delay your CAT scan appointment.

Drink only clear liquids after midnight the night before your scan. Clear liquids include things you can see through . Examples include clear broth, tea, strained fruit juices, strained vegetable soup, black coffee, and ginger ale. You may also eat plain Jell-O.

CT Scans are Inaccurate for Treatment Monitoring

After cancer treatment, a CT scan is unable to determine whether masses leftover are cancerous: The CT scan might show signs of cancer, but that cancer might not be active. For example, it could be scar tissue left over from cancer killed off by your treatment.

Can A Ct Scan Tell If A Lymph Node Is Cancerous

Computed Tomography Scans

CT scans are different than standard x-rays because they create a series of pictures taken from different angles and produce much clearer images. A CT scan of the chest or abdomen can help detect an enlarged lymph node or cancers in the liver, pancreas, lungs, bones and spleen.

Further Tests For An Enlarged Prostate

Depending on your test results, you may have further tests to find out what is causing your symptoms.

Bladder pressure test

This shows how well your bladder is working. The doctor passes thin tubes up your penis and fills your bladder with a clear liquid. Thin tubes are also placed in your back passage . The tubes measure the pressure in your bladder, back passage and urethra. You will then be asked to empty your bladder, and the pressures will be measured again while you urinate. You may have this test if youre thinking about having surgery to treat an enlarged prostate, or if youve had surgery but your symptoms havent improved or are getting worse.

Flexible cystoscopy

This shows whether you have a blockage or any abnormal tissue in your urethra or bladder. A doctor or specialist nurse will pass a thin tube up your penis into your bladder. Youll be able to feel the tube moving, but anaesthetic gel will be used to make the test more comfortable. The tube has a light and camera on the end so the doctor or nurse can see the inside of your urethra and bladder on a screen. You may have this test if you have severe urinary symptoms, blood in your urine or pain, or if you often get urine infections. You may also have this test if your doctor thinks your urethra or the opening of your bladder may be too narrow this is called a stricture.

What Happens After The Prostate Tests

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.

An antibiotic may be prescribed for 1 or 2 days to prevent infection.

Patients with signs of infectionincluding pain, chills, or fevershould call their health care provider immediately.

Referral To A Urologist

The GP may refer you to a;urologist or other appropriate specialist;if:

  • previous treatments;have not helped your urinary problems
  • a urinary infection;does not go away or comes back regularly
  • you cannot;fully empty your bladder
  • you have kidney problems
  • you have stress incontinence, which is when urine leaks out at times when your bladder is under pressure; for example, when you cough or laugh

You should also see a specialist if the GP is concerned that your symptoms could be caused by cancer, although for most men this is not the cause.

To help find out what might be causing your symptoms and decide how to manage them, you should be offered extra tests to measure:

  • how fast your urine flows
  • how much urine is left in your bladder after you have peed

You may also be offered other tests, depending on your symptoms or the treatment you and your doctor are considering.

Further Testing For Advanced Cancer

If there’s a significant chance the cancer has spread from your prostate to other parts of the body, further tests may be recommended.

These include:

  • an MRI scan, CT scan or PET scan these scans build a detailed picture of the inside of your body
  • an isotope bone scan, which can tell if the cancer has spread to your bones a small amount of radiation dye is injected into the vein and then collects in parts of the bone where there are any abnormalities

When You Need Themand When You Dont

It is normal to want to do everything you can to treat prostate cancer. But its not always a good idea to get all the tests that are available. You may not need them. And the risks from the tests may be greater than the benefits.

The information below explains why cancer experts usually do not recommend certain imaging tests if you are diagnosed with early-stage prostate cancer. You can use this information to talk about your options with your doctor and choose whats best for you.

How is prostate cancer usually found?

Prostate cancer is cancer in the male prostate gland. It usually grows slowly and does not have symptoms until it has spread. Most men are diagnosed in the early stages when their doctor does a rectal exam or a PSA blood test. PSA is a protein made in the prostate. High levels of PSA may indicate cancer in the prostate.

If one of these tests shows that you might have prostate cancer, you will be given more tests. These tests help your doctor find out if you actually have cancer and what stage your cancer is.

What are the stages of prostate cancer?

Prostate cancer is divided into stages one to four . Cancer stages tell how far the cancer has spread.

Stages I and II are considered early-stage prostate cancer. The cancer has not spread outside the prostate. However, stage II cancer may be more likely to spread over time than stage I cancer. In stages III and IV, the cancer has already spread to other parts of the body.

Imaging tests have risks.

You’ll be asked to complete;a;questionnaire;to assess your symptoms. Each question has;five possible answers that carry a score, and;your overall score;is used to assess the severity of your symptoms.

The checklist includes the following questions.

Over the past month:

  • How often have you had the sensation of not completely emptying your bladder after urinating?
  • How often have you had to urinate again less than two hours after finishing urinating?
  • How often have you found that you stopped and started again when urinating?
  • How often have you found it difficult to postpone urination?
  • How often have you had a weak stream of urine?
  • How often have you had to push or strain to begin urinating during the course of one night?
  • How;often have;you had to;get up during the night to urinate?

After your GP has assessed the severity your symptoms, they’ll aim to rule;out other conditions;with similar symptoms using certain tests.

What Is A Ct Scan

A CT scan is a test that uses;x-rays and a computer to create;detailed pictures of the inside of your body. It takes pictures;from different angles. The computer puts them together to make a 3 dimensional image. ;

CT stands for computed tomography.

You usually have a CT scan in the x-ray department as an outpatient. A radiographer operates the scanner. The whole appointment can take up to an hour and a half depending on which part of your body they are scanning.;

Screening For Prostate Cancer

Prostate cancer is typically treatable if caught early. More than 90 percent of prostate cancers are found when the disease is in the beginning stages, confined to the prostate and nearby organs.

Unlike screenings for breast;and colon cancers, there are no universal screening guidelines for prostate cancer. The U.S. Preventive Services Task Force recommends that men age 55 to 69 weigh the benefits and risks before deciding whether they should undergo screening, which is typically performed with a blood test that measures levels of a protein called prostate-specific antigen;.

However, men in high-risk groupssuch as those who are of African-American descent and/or have a first-degree relative diagnosed with prostate cancer before age 65should consider speaking with their doctor about starting screenings at an earlier age.

Men older than 70 shouldnt be routinely screened for prostate cancer, according to the USPSTF.

Regardless of age or risk factors, men should get checked if they suddenly experience issues with urination, erectile dysfunction or unexplained pain.

The USPSTF suggests that, before deciding on a screening, men should seek expert advice about the benefits and harms of screening. Risks may include:

  • False positives
  • Complications and side effects from biopsies to confirm a diagnosis
  • The possibility that a prostate cancer diagnosis wont extend lifespan or improve quality of life

Genetic Testing For Prostate Cancer

You may hear a lot about genetics or genomics. Both terms are related to genes and cell DNA, but they are different. These tests are being used to learn more about the DNA of cancer cells, and link DNA mutations with treatments. In the future, genetic testing may be the first step doctors take when diagnosing prostate cancer.
