Cancer is a disease of abnormal, unregulated cellular growth that can lead to the formation of solid tumours in bone or soft tissue, or abnormal cells in the bloodstream (haematological cancers like leukaemia). One in two Australians will be diagnosed with a form of cancer before their 85th birthday. Medical treatment for cancer can include surgery, radiation therapy, chemotherapy, hormonal therapy and immunotherapy. An increasing number of people live with the side effects of cancer and its treatment for many years. This has shifted how the health community thinks about cancer, and it is now considered a chronic disease.
