Radiation oncology is a medical specialty that uses high-energy radiation beams to either treat cancer or to reduce pain and other symptoms associated with cancer.
The Radiation Oncology team includes highly trained and qualified medical oncologists, radiation therapists, radiation oncology nurses, and supportive care team members. They use advanced and innovative technologies to deliver safe and effective radiation to cancer patients with minimal side effects.
The key highlights of this department include:
- Conventional radiation therapy: It uses high-energy radiation beams in the form of X-rays, gamma rays, or photons to destroy the tumour cells or to reduce the chance of its recurrence. Radiation therapy is often combined with chemotherapy for effective results. This is known as chemo-radiation.
- 3D Conformal Radiation Therapy (3DCRT): It is technique that uses advanced imaging technologies to generate three-dimensional images of a tumor and nearby organs. This improves the accuracy of treatment. BY using 3DCRT, an effective dose of radiation can be delivered directly to cancerous cells.
- Intensity Modulated Radiation Therapy (IMRT): It is an advanced radiation treatment that uses computerized programs to calculate and deliver precise radiation to tumors while reducing radiation exposure of healthy tissues. IMRT is widely recommended in the treatment of head and neck, pelvic, and thoracic tumors.
- Volumetric-Modulated ARC Therapy (VMAT)/ RapidArc: This is an advanced form of Intensity-modulated radiation therapy that is used for delivering radiation therapy with varying intensities aimed at tumours near sensitive body organs.
- Stereotactic Radiosurgery (SRS): It delivers a precise amount of radiation beam to treat small tumours in the brain. When SRS is performed to treat tumours located on other regions of the body. It is referred as Stereotactic Body Radiation Therapy.
- Stereotactic Body Radiation Therapy (SBRT): It involves the delivery of a single high dose radiation treatment or a few fractionated radiation treatments from many different angles around the body. SBRT is basically used to treat small, early-stage lung cancer and pancreatic cancer. It is also used for cancers that have spread to the lung, liver, adrenal gland, or spine.
- Brachytherapy (internal radiation therapy): In this therapy, the radiation source is placed inside the body near the tumor to deliver high dose radiation. Depending on the site of cancer, radiations can be delivered by intracavitary, intraluminal, and multi-catheter methods.
- Extracorporeal Radiotherapy (ECRT): It is usually done as a part of limb-salvage surgery to save the limb. This procedure involves taking out cancerous bone and treating it with radiation and then placing it back again.
