PSMA PET-CT and Prostate Cancer: What Patients Should Know?

In the past, prostate cancer was difficult to detect and monitor. However, recent advances in medical imaging have made it possible to detect and stage prostate cancer with greater accuracy. PSMA PET-CT is one such modality that has shown great promise in the detection and staging of prostate cancer. Here, we will provide an overview of how PSMA PET-CT works and what patients should know about this important diagnostic tool.

What is PSMA PET-CT Scan?

A PSMA PET-CT scan is an imaging test that uses special cameras and computer technology to create 3D pictures of areas inside the body. A PET (positron emission tomography) scan shows how well organs and tissues are functioning. A CT (computed tomography) scan makes detailed pictures of structures inside the body, such as organs, bones, and blood vessels. A PSMA PET-CT scan combines these two types of scans into one test.

PSMA (prostate specific membrane antigen ) is a protein found on most prostate cancer cells. This test uses a small amount of a radioactive drug that attaches to PSMA molecules. The scanner tracks where the radioactive drug goes in your body. The areas that light up on the scan may be abnormal. These areas may be further evaluated with other tests, such as a biopsy.

When to Have a PSMA PET-CT Scan?

PSMA can be overexpressed in prostate cancer. By targeting the PSMA, PSMA PET-CT can more accurately detect and stage prostate cancer. PSMA PET-CT can also be used to monitor the progress of treatment. This is because PSMA PET-CT can show how well treatment is working by tracking changes in tumour size or location. This information is important because it can help doctors tailor treatment to the individual needs of each patient.

Patients who have been diagnosed with prostate cancer may have this test to:

  • Find out if cancer has spread from the prostate to other parts of the body
  • Find out if cancer has come back after treatment
  • Guide treatment decisions, such as surgery or radiation therapy
  • PSMA PET-CT scans are better than a regular PET-CT scan for prostate cancer as it is a new imaging modality to determine the extent of prostate cancer after diagnosis

PSMA PET-CT is a safe and effective way to detect and stage prostate cancer. In most cases, the procedure is well tolerated and there are no serious side effects. As with any medical procedure, there are some risks such as radiation exposure and risks associated with the injection of contrast material that patients should be aware of.

Warning Signs of Prostate Cancer

Early detection is key when it comes to fighting prostate cancer, and there are a few symptoms that men should be on the lookout for. One of the most common signs is difficulty urinating, as the cancer can block the urethra and make it difficult to empty the bladder. In addition, many men with prostate cancer experience urinary frequency or urgency, pain during urination, and blood in the urine. If you are experiencing any of these symptoms, it is important to see a doctor for a diagnosis. With early treatment, prostate cancer is highly treatable, so don't hesitate to seek medical help if you are concerned about your health.

Seek Early Diagnosis and Treatment for Prostate Cancer

It is critical to see a doctor as soon as you experience any of the above symptoms. With proper scans, staging and diagnosis, your doctor can then advise you on treatment. Treatment options for prostate cancer include surgery, radiation, chemotherapy, hormonal therapy, targeted therapy, theranostics and immunotherapy. We also offer hereditary genetic screening to patients if appropriate.
