Cancer is caused by gene mutations. one type of gene called the oncogene assists in normal cell growth and is mutated to assist in the uncontrolled growth of tumors. The risk of gene mutations can also be increased if exposed to carcinogens. Carcinogens are cancer-forming agents that can increase your risk of cancer. some common carcinogens are Asbestos And nickel these can cause lung cancer. some other Carcinogens are Alcohol and tobacco which increase the risk of oral cancer. -
Cancer is caused by genetic damages in a cell. This genetic damage makes cells referred to as malignant cells. -
malignant cells are formed after a cell experiences genetic damage. malignant cells are cells that split more often than normal cells. when malignant cells are attacked by medicine they target cells that are very rapidly splitting like the malignant cells but the medicine also attacks hair follicle cells that also rapidly divide -
Cancer cells behave very abnormally and dangerously compared to normal cells. some of these differences are that they
are immature and don’t develop into mature cells, avoid the immune system, ignore signals that tell them to stop splitting
don’t stick together very well and can spread to other parts of the body and grow into and damage tissues and organs -
When cells Divide rapidly they form a lump of tissue known as a tumor. Tumors can cause be very destructive in the body they can apply pressure on neighboring organs or tissues. Tumors can also invade tissues or organs and in the process damaging or Disabling them. Tumors can be either malignant meaning harmful and cancerous or benign. benign tumors don't spread and can be removed without them growing back
