How is cancer treated

Each type of cancer will be treated differently, depending on what doctors have found to be the best treatment for that type of cancer. You may receive one or a combination of the following treatments at different times in your therapy.

  • Surgery is often used to treat cancer. Sometimes, taking out the tumour may be the only treatment needed.
  • Bone marrow or stem cells transplants involve placing healthy cells from a donor into a patient which allows the body to regenerate a functioning immune system and healthy blood cell production.
  • Chemotherapy and/or radiation therapy  are also used to kill any cancer cells still in the body.
    • Chemotherapy is medicine that treats cancer by destroying fast-growing cells (which includes cancer cells). Chemotherapy can be given in different ways, depending on the type and location of the cancer and the specific drug used. It is usually taken by mouth or through a vein (systemic chemotherapy), allowing the medicine to reach the entire body. Treatment is given in cycles, which include a set number of treatment and rest days, planned to maximise effectiveness and allow recovery.
    • Radiation therapy delivers high energy x-rays that damage and destroy rapidly growing cells, such as cancer cells.
  • Biological therapies, like immunotherapy and targeted therapy, are newer treatments which being used in some contexts.
    • Immunotherapy strengthens the capacity of the immune system to fight the cancer
    • Targeted cancer therapies block the growth and spread of cancer, while limiting or avoiding damage to normal cells and tissues.
