Oncare offers radiation therapy in Delhi NCR, planned by a team of radiation oncologists, medical oncologists and surgical oncologists who review each case together. This page explains what radiation therapy is, who treats you, the techniques used, how many sessions to expect, side effects and cost, so you know what to ask before you start.
Radiation therapy (radiotherapy) uses high-energy rays to damage the DNA of cancer cells so they stop growing and shrink. It is planned and supervised by a radiation oncologist, also called a radio oncologist or radiotherapy specialist. It can be used alone or together with surgery or chemotherapy, depending on the cancer type and stage. Most people have sessions on weekdays over several weeks, though some techniques need far fewer.
Radiation damages cancer cells, which are generally less able to repair themselves than healthy cells. Modern techniques aim to limit the dose to nearby healthy tissue. Some exposure still happens, which is why side effects can occur.
Your stage and grade help decide which of these applies.
A radiation oncologist is a doctor who specialises in treating cancer with radiation. You may also hear the terms radio oncologist, radiotherapy specialist, radiation doctor or cancer radiation specialist. A consultant radiation oncologist is a senior specialist who leads your radiation treatment plan. A radiation oncologist:
A radiation oncologist is not the same as a radiologist. A radiologist reads scans and X-rays. A radiation oncologist treats cancer with radiation.
Radiation is used for many cancers, including breast cancer, lung cancer, prostate, head and neck, cervical cancer, brain and colorectal cancers. It can also relieve symptoms when comfort is the goal.
Technique | What it does | Often used for |
|---|---|---|
3D-CRT (3D conformal) | Shapes the beams to the 3D form of the tumour | Many common cancers |
IMRT | Varies beam intensity to shape the dose precisely | Tumours near sensitive structures |
IGRT | Uses imaging during treatment to confirm tumour position every session | Tumours that can move, such as in the lung or prostate |
VMAT | Delivers radiation in a continuous arc, which can shorten each session | Complex shapes, many sites |
SBRT / SRS | High, focused doses in a few sessions | Small, well-defined tumours |
A radioactive source placed inside or next to the tumour. | Cervical, prostate and other cancers | |
Tomotherapy | A form of IMRT delivered by a machine that combines a CT scanner with a rotating radiation beam | Long or complex treatment areas and multiple targets |
Which technique you get depends on the cancer, its location, and your overall health. Your radiation oncologist will explain the choice.
