Document Summary
Cancer is characterization by genetic and biochemical defects. Biochemistry and molecular biology provide avenues for cures. Cancer is: the leading cause of death in north america. Benign tumours: are contained within the originating tissue. Malignant tumours: are able to invade surrounding tissues and are thus much more difficult to treat. Benign tumor (left): it"s encapsulate and can be surgically removed. They do not move from their place of origin. Malignant tumor (right): these tumors are not contained, so they can move throughout the body. A very difficult form of cancer to treat. Some genes that result in cancer can be inherited. So we know cancer is a genetic disease because it can be inherited. Chemicals that damage dna can result in cancer= carcinogens. Mutagens=things that cause dna damage, can cause cancer because cancer is a genetic disease, and vice versa. ** causes cells to divided and there is a greater chance that they will become cancerous.
