Chemotherapy is the use of anti-cancer (cytotoxic) drugs to destroy cancer cells (including leukaemia and lymphoma).

There are over 50 different .

The type of chemotherapy treatment you are given depends on many things, but particularly:

  • the type of cancer you have
  • where the cancer started in your body
  • what the cancer cells look like under the microscope
  • whether the cancer has spread to other parts of your body.

Chemotherapy may be used alone to treat some types of cancer. It may also be used with other types of treatment such as , , , biological therapies, or a combination of these.

Chemotherapy drugs can stop cancer cells dividing and reproducing themselves. As the drugs are carried in the blood, they can reach cancer cells anywhere in the body. They are also taken up by some healthy cells. Healthy cells can repair the damage caused by chemotherapy, but cancer cells cannot and so they eventually die.

Different chemotherapy drugs damage cancer cells in different ways. If a combination of drugs is used, each drug is chosen because of its different effects.

Unfortunately, as the chemotherapy drugs can also affect some of the healthy cells in your body, they can cause unpleasant side effects. However, damage to the healthy cells is usually temporary and most side effects will disappear once the treatment is over.

Healthy cells in certain parts of the body are especially sensitive to chemotherapy drugs; these parts of the body include:

  • the bone marrow (which makes blood cells)
  • the hair follicles
  • the lining of the mouth
  • the digestive system.

Chemotherapy is usually given as a series of sessions of treatment. Each session is followed by a rest period. The session of chemotherapy and the rest period is known as a cycle of treatment. A series of cycles makes up a course of treatment.

Each session of chemotherapy destroys more of the cancer cells, and the rest period allows the normal cells and tissues to recover.

In the past 50 years our knowledge of how best to use radiation has vastly improved.In the past 10 years we have made huge improvements in our ability to deliver high-dose radiation with tremendous accuracy. The use of the latest radiation oncology machines, such as high energy linear accelerators, means we can now access the cancerous area seen on scans with greater accuracy and speed of treatment delivery.

Used alone, or in combination with other approaches such as surgery or chemotherapy, it cannot only cure many patients, but also control tumour to reduce symptoms and improve quality of life. Over half of all patients with cancer will require radiation therapy at some point as part of their overall cancer treatment program. Radiation therapy is a highly effective treatment modality for patients with cancer.
