Cancer: Define, Types, Treatment & Facts

Cancer cells usually group or clump together to form tumors. Our bodies are made up of millions of tiny cells. They all have different jobs to do and they are busy dividing splitting into two, making more new cells to do their job, eg. New skin cells take the place of old skin cells, which are rubbed off the skin’s surface when they die.  Leukemia is a cancer of the blood. Leukemia cells are sick immune blood cells that do not work properly and crowd out healthy blood cells. Leukemias are the most common childhood cancers. The cause of most childhood cancers is unknown, and at present childhood cancer cannot be prevented. The majority of children with cancer require rounds of chemotherapy to treat their disease. Many require surgery and/or radiation to remove a tumor. For some, a bone marrow transplant is their only hope of survival.

Cancer is a group of diseases that involve abnormal increases in the number of cells, with the potential to invade or spread to other parts of the body.

  1. Carcinoma – The skin or in tissues that line or cover internal organs when cancer begins in. These include different subtypes, including adenocarcinoma, basal cell carcinoma, squamous cell carcinoma and transitional cell carcinoma.
  2. Sarcoma – cancer that begins in the connective or supportive tissues such as bone, cartilage, fat, muscle or blood vessels.
  3. Leukemia – cancer that starts in blood-forming tissue such as the bone marrow and causes abnormal blood cells to be produced and go into the blood
  4. Lymphoma and myeloma – cancers that begin in the cells of the immune system Open a glossary item
  5. Brain and spinal cord cancers – these are known as central nervous system cancers.

Treatment for cancer

  1. Immunotherapy: Immunotherapy is a type of treatment that helps your immune system fight cancer. Get information about the types of immunotherapy and what you can expect during treatment.
  2. Surgery: When used to treat cancer, surgery is a procedure in which a surgeon removes cancer from your body. Learn the different ways that surgery is used against cancer and what you can expect before, during, and after surgery.
  3. Radiation therapy is a type of cancer treatment that uses high doses of radiation to kill cancer cells and shrink tumors. Learn about the types of radiation, why side effects happen, which ones you might have, and more.
  4. Hormone therapy is a treatment that slows or stops the growth of breast and prostate cancers that use hormones to grow. Learn about the types of hormone therapy and side effects that may happen.

Cancer facts

  • Cancer is the uncontrolled growth of abnormal cells anywhere in a body.
  • There are over 200 types of cancer.
