Document Summary
Cancer is an age related disease; the longer one lives, the higher the risk of cancer. Cervical cancer is caused by hpv (a virus). Cancer is a genetic disease that involved multiple mutations, not single mutations. Certain inherited mutations could predispose one to cancer because it is multifactorial. Not all cancers involve somatic parts in an individual; they can be passed along like a disease. Tasmanian devils can pass their tumors on each other. Oncogenesis is the formation of cancer that begins with the loss of cell cycle control. Tumors begin with a loss of cell cycle control. Once a tumor completely loses the ability to undergo mitosis, it can become transformed or immortalized. Carcinoma refers to cancer of epithelial origin (skin cancer). Sarcomas are cancers that arise from connective tissues (bone and cartilage). Lymphoma is the cancer in the cells of the immune system (e. g b cells). Cancer is the loss of cell cycle control.
