Around half of all cancer patients receive radiation therapy.
Destroying cancer cells
There are many ways to have radiation therapy but they all work in a similar way. Carefully controlled high-energy X-rays destroy or damage cancer cells. This stops them growing or spreading.
Radiation therapy is usually delivered in daily intervals called ‘fractions’. This allows time between treatments for the healthy cells to repair and the cancer cells to die off.

At GenesisCare, we’re always pushing the boundaries of technology to develop better radiation therapy treatments. Targeting the cancer cells in tumours without damaging the surrounding healthy tissue.
What is radiation therapy?
Our radiation therapies and tools
External beam radiation therapy uses high-energy radiation beams to destroy cancer cells. Before your treatment begins, we’ll take some imaging scans to establish the precise shape, size and location of the tumour. If your treatment is after your tumour removal surgery, then we’ll take scans to examine the area where the tumour was removed.
Deep Inspiration Breath Hold (DIBH) is a simple technique used to treat cancer in the breast or chest wall. It’s precisely targeted so there’s less chance of damage to the heart and lungs.
IMRT is a ‘conformal’ radiation therapy. This means radiation beams are shaped to surround the treatment area, so it avoids damaging surrounding healthy tissue.
Tomotherapy is a type of IMRT. It combines the technologies of a CT scanner (providing 3D images) and an IMRT machine to accurately target a tumour.
• Creating a 3D image of the tumour means we can target the beams precisely. We adjust the treatment to the size, shape and location of the treatment area
• The tumour is given a very high dose of radiation. The healthy surrounding tissue gets a much lower dose, reducing the risk of side-effects
Volumetric modulated arc therapy (VMAT) is a type of IMRT. VMAT is very accurate and maximises radiation to the tumour. The surrounding healthy tissue receives a much lower dose, reducing the risk of side-effects.
• VMAT delivers a continuous beam of radiation therapy in an arc that moves around the tumour. It automatically changes the beam shape and radiation dose as it moves
• Treatment sessions with VMAT are usually short – around 10 minutes
• VMAT can be used when the tumour is close to critical organs. It helps them avoid being damaged by radiation
IGRT uses X-rays and scans before, and during, your treatment. It’s used to verify your position and anatomy before the treatment machine is turned on.
• The scans show the exact shape, size and location of the tumour. We can then make tiny adjustments to precisely target the treatment area
• IGRT can target cancers that move during, or between, treatment sessions. For example, lung cancers that move as you breathe. Or prostate cancer that can move depending on whether your bowel is full or empty
SRS is a non-surgical treatment for some types of cranial cancers. It delivers high doses of precisely targeted radiation therapy which reduces damage to nearby healthy tissue.
• It’s often used to treat small tumours of the brain
• It’s accurate to within one to two millimetres
SABR targets tumours in the body with high doses of radiation therapy. It destroys cancer cells with minimum damage to surrounding healthy tissues.
Gamma Knife isn’t a physical knife, and there’s no surgery involved. It’s a non-invasive alternative to neurosurgery.
SGRT uses sophisticated 3D camera technology to accurately target and kill cancer cells.
SpaceOAR hydrogel treatment is an option for men having radiation therapy for prostate cancer. It’s a water-based soft gel implant that temporarily creates a small gap between the prostate and the rectum. This gap protects the rectum from radiation exposure during prostate radiation therapy, meaning fewer side-effects.
Brachytherapy is a type of radiation therapy. It involves placing a tiny amount of radioactive material into, or next to the tumour. Depending on the type of cancer being treated, material may be inserted using a very thin needle or wire, an applicator, or radioactive beads or ‘seeds’.
