Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. These contrast with benign tumors, which do not spread. Possible signs and symptoms include a lump, abnormal bleeding, prolonged cough, unexplained weight loss, and a change in bowel movements. While these symptoms may indicate cancer, they can also have other causes. Over 100 types of cancers affect humans. Treatments may include surgery, chemotherapy and radiation therapy.
Breast cancer: Its treatment depends on the stage of cancer. It may consist of chemotherapy, radiation, hormone therapy and surgery.
Prostate cancer: Some types of prostate cancer grow slowly. In some of these cases, monitoring is recommended. Other types are aggressive and require radiation, surgery, hormone therapy, chemotherapy or other treatments.
Basal cell cancer: Treatments include prescription creams or surgery to remove the cancer. In some cases radiation therapy may be required.
Skin cancer (melanoma): Treatment may involve surgery, radiation, medication or in some cases, chemotherapy.
Colon cancer: Colorectal cancer treatment depends on the size, location and how far the cancer has spread. Common treatments include surgery to remove the cancer, chemotherapy and radiation therapy.
Lung cancer: Treatments vary but may include surgery, chemotherapy, radiation therapy, targeted drug therapy and immunotherapy.
Leukemia: Treatment is highly variable. For slow-growing leukaemias, treatment may include monitoring. For aggressive leukaemias, treatment includes chemotherapy that's sometimes followed by radiation and stem-cell transplant.
Lymphoma: Treatment may involve chemotherapy, medication, radiation therapy and rarely stem-cell transplant.
