What is cancer?

Answer 1

Go to wikipedia.com, it tells you everthing you need to know about almost anything. :]

Answer 2

cancer-Cancer is actually a group of many related diseases that all have to do with cells. Cells are the very small units that make up all living things, including the human body. There are billions of cells in each person's body.

Cancer happens when cells that are not normal grow and spread very fast. Normal body cells grow and divide and know to stop growing. Over time, they also die. Unlike these normal cells, cancer cells just continue to grow and divide out of control and don't die.

Cancer cells usually group or clump together to form tumors. A growing tumor becomes a lump of cancer cells that can destroy the normal cells around the tumor and damage the body's healthy tissues. This can make someone very sick.

Sometimes cancer cells break away from the original tumor and travel to other areas of the body, where they keep growing and can go on to form new tumors. This is how cancer spreads. The spread of a tumor to a new place in the body is called metastasis

Answer 4

Cancer is a class of diseases or disorders characterized by uncontrolled division of cells and the ability of these cells to spread, either by direct growth into adjacent tissue through invasion, or by implantation into distant sites by metastasis (where cancer cells are transported through the bloodstream or lymphatic system). Cancer may affect people at all ages, but risk tends to increase with age. It is one of the principal causes of death in developed countries.

There are many types of cancer. Severity of symptoms depends on the site and character of the malignancy and whether there is metastasis. A definitive diagnosis usually requires the histologic examination of tissue by a pathologist. This tissue is obtained by biopsy or surgery. Most cancers can be treated and some cured, depending on the specific type, location, and stage. Once diagnosed, cancer is usually treated with a combination of surgery, chemotherapy and radiotherapy. As research develops, treatments are becoming more specific for the type of cancer pathology. Drugs that target specific cancers already exist for several cancers. If untreated, cancers may eventually cause illness and death, though this is not always the case.

Answer 5

Cancer is characterized by the uncontrolled division of cells, the immune system is affected and the person suffers as the cancer spreads.More details and information at http://candp.org/

Answer 6

Cancer describes a range of diseases in which abnormal cells proliferate and spread (metastasise) to other parts of the body. If the spread is not controlled, it can result in death. Other terms for cancer are tumours and neoplasms, although these terms can also be used for non-cancerous growths.

Answer 7

Cancer is an abnormal divison of cells that can occur in any part of the body. Generally, most of the cells of the body stop dividing themselves after a certain period time, however, canceruos cells stop recognising that neurochemical signal to stop dividing themselves and continue to divide or may start dividing at any poiint of time.
