Cancer is a group or clump of many related diseases that have to do with cells. The cells are the smallest units that make up all living things. Cancer cells grow and from tumors. Tumors that grow become cancer cells that destroy the normal cells around the tumor and damage the body's healthy tissues. Cancers cells can travel to other parts of the body. This is how new tumors form. The cells that are cancerous are cells that have grown out of control. Some cancer don't form tumors, but instead the cancer is in the blood. The cancer grows in the body's tissue. Cell mutation causes normal cells to form into cancer. These cancer cells will then multiply and form more cancer.
