Metastasis refers to the spread of cancer cells from the site of origin to other areas of the body through the lymph or the bloodstream. The metastatic cells grow rapidly and damage the normal tissues surrounding the cancerous cells. They travel to distant areas through the blood and form a new tumour.
Types of treatment
The treatment of metastasis depends upon the location, and type of cancer. Chemotherapy, immunotherapy, surgery, radiation therapy are the treatments provided for metastasis. There are several treatments that are used to ease the side effects of cancer.
