There are five types of cancer:
- Carcinomas. These are formed in the tissues that cover a surface or line internal organs of the body.
- Sarcomas develop in connective tissue and affect bones and soft tissue.
- Leukaemias are found in the blood and the blood-forming tissues.
- Lymphomas affect the lymphatic system that normally acts as a filter of impurities on the body.
- Myelomas are tumours that arise in plasma cells in the bone marrow.
