Radiation Therapy for Prostate Cancer – Oncologist Explains


 

 

Radiation therapy is a treatment that uses high-energy rays or particles to kill prostate cancer cells. Radiation can be supplied in a variety of ways, including brachytherapy (in which seeds are implanted in the patient's body) and external beam radiation (in which energy is projected through the skin). Prostate cancer radiation therapy is best given by a skilled radiation oncologist in Kolkata working in advanced cancer treatment facilities.

Radiation Therapy Uses

Radiation therapy can be used to:

  • Treat early-stage prostate cancer as well as more advanced tumours that have migrated outside the prostate

  • Provide combinational therapy with other treatments like hormone deprivation

  • Treat recurrent prostate cancer after surgery

  • Reduce the size of the tumour and enhance survival and quality of life in men with limited spreading (oligometastatic) prostate cancer

  • Reduce the chance of fractures by slowing cancer growth

  • Palliate symptoms for advanced cancer discomfort

Radiation Therapy for Prostate Cancer: What Are the Different Types?

External Beam Radiation Therapy (EBRT)

 

This is the most popular and painless type of radiation therapy. X-ray beams are focused on the cancerous spots throughout each treatment session. Oncologists can adjust the dosage intensity and radiation beams to better deliver high doses of radiation to tumour cells while delivering lesser doses to healthy tissues in the surrounding area.

 

Intensity-Modulated Radiation Therapy (IMRT)

 

External beam radiation delivered by linear accelerators is a sophisticated form of external beam radiation (LINACS). Oncologist in Kolkata can adjust the strength and form of radiation beams to better focus radiation to the prostate while limiting exposure to surrounding bladder and rectal tissue.

 

Proton Beam Therapy (PBT)

 

Proton treatment is an alternative to EBRT that is becoming increasingly popular now that more centres with the necessary equipment are available. The procedure has progressed from a passive scattering method to scanning proton beam therapy.

 

Stereotactic Body Radiation Therapy (SBRT)

 

SBRT (or SABR) uses modern imaging techniques to deliver massive doses of radiation to a specific location in a short amount of time. The names of the equipment that provide the radiation are widely used to refer to SBRT.

 

Image-Guided Radiation Therapy (IGRT)

 

The use of daily imaging to monitor the position of the tumour target is referred to as IGRT. This usually entails a low-dose X-ray (kV) or a CT scan (cone beam CT). Gold or platinum fiducial markers may be implanted in the prostate before therapy for some patients.

 

Brachytherapy

 

Seed implantation, interstitial radiation therapy, and internal radiation therapy are the different terms used to describe brachytherapy. Tiny radioactive seeds (approximately 0.8 millimetres thick and 4.5 millimetres long) are implanted by the best radiation oncologist in Kolkata into the prostate using needles that enter the skin slightly behind the scrotum for permanent (low dosage rate) brachytherapy. For several months, the seeds emit radiation that kills cancer cells in the local vicinity, until the radioactivity fades.

How Radiation Therapy Helped Improve My Prostate Cancer

Image
  My hometown of Burdwan is 65 km from Kolkata. Every workday for 8 weeks, I drove there and back for radiation therapy sessions. In 2019, I was looking forward to a long future with my family and friends, as well as a continuous, active presence in our business community. However, things changed when I started experiencing frequent night-time urination and burning sensation during urination. I felt something’s not right! My local physician recommended a few tests, including a PSAD and prostate biopsy. Then, a series of PSA (Prostate Specific Antigen) screening tests revealed that PSA levels were significantly high. I also underwent a biopsy since I was concerned about prostate cancer. When I got the results, I was taken aback. They took 17 tissue samples, all of which were cancerous. My physician suggested that I should consult the best radiation oncologist in Kolkata . I knew I was in serious trouble!   I immediately scheduled an appointment with the oncologist at the A...

Rectal Cancer Treatment Using Radiation Therapy

Image
  Introduction Recently diagnosed with rectal cancer? Then radiation therapy is your best option, according to a   rectal cancer specialist in Kolkata . When cancer spreads to lymph nodes, or beyond the wall of the rectum, as well as for locally recurrent rectal cancers, radiation therapy is required. Imaging before radiation Before employing radiation therapy,  the best radiation oncologist in Kolkata and  his team of experts use imaging techniques to determine where the tumors are located in the rectum and how far the spread is.  These images allow radiation oncologists to identify where the cancer is located and plan their treatment accordingly. Imaging techniques can include: Rectal protocol MRI : In this technique, images are taken from specific angles to gain the best look at the rectum and surrounding tissue. This imaging technique is recommended by the  best radiation oncologist in Kolkata .  Transanal ultrasound (TRUS) : It is sometimes call...
