Prostate Cancer - What Is The Utility Of PSMA PET Scan & Dota Scan?

In recent years, there has been an emerging trend of resorting to customized treatment for different types of cancer. These treatments vary from individual to individual, depending on the severity of their condition. PSMA PET scan and DOTA scan are two such procedures used in the treatment of prostate cancer.

Before identifying the benefits of these scans, let us have a look at the risks of prostate cancer.

Prostate Cancer- What is it?

Prostate cancer shows up in the prostate gland of men, which produces the fluid that transfers and nourishes the sperm. It is a very commonly occurring condition in men and early treatment can cure it completely.

Symptoms of Prostate Cancer:

Prostate cancer starts showing its symptoms from the middle stages. One should seek medical help if he observes the following warning signs-

• Pain while urinating
• Bone pain
• Reduction in force of urine
• Erectile Dysfunction
• Presence of blood in semen

With increasing age and obesity, there remains a high chance of developing prostate cancer.

What is PSMA PET scan?

It is an effective and reliable mode of diagnosis to identify the extent of prostate cancer. It is also known as Prostascint scan. This scan is recommended for patients in the early stage of cancer and to determine whether the disease has spread to the pelvic lymph nodes.

In this process, the patient is injected with an antibody and a radioactive material that can be detected by cameras. The doctor then sees a three-dimensional picture of the affected area on the monitor. The complete process takes three days to finish.

Benefits of PSMA PET scan:

• Helps to determine the position and range of a tumour
• Helps the doctor to plan effective methods of treatment to eradicate a tumour completely
• Helps to predict the result of treatment up to a certain extent, unlike other imaging tests

What is DOTA scan?

It is a highly advanced scan used to detect the spread and sensitivity of tumours concerning prostate cancer. The molecules injected during the scan attaches itself to the neuroendocrine tumours known as carcinoids.

Benefits of DOTA scan:

• Helps to detect the exact location of a tumour
• Helps the doctor to plan for effective radioactive therapies
• Helps to identify the exact stage of a cancerous tumour

Both PSMA and DOTA scans are the fruits of modern scientific research and go a long way in eradicating cancerous cells from the body. Early detection of the disease with these scans increases the chance of being cured of the disease.
