How do you get cancer?

Answer 1

All living things - ourselves included - are made up of cells. Cells are microscopic packages of living material and we have billions of them. They come in many different types: liver cells, brain cells, blood cells and so on. In the normal adult, cells only grow and divide slowly and under very tight control to make sure that the number of cells in each tissue stays the same. Cancer begins when one cells changes and startys growing and dividing rapidly and out of control. This one cells divides to give two cells, then four, eight and so on until they form growing mass of cancer cells - called a tumour.

That's one of the toughest questions of modern times. Cancer isn't just one disease, and it has many causes, most of which are not yet fully understood. There is an established link between some chemicals and a high incidence of cancer, but it isn't certain that if a particular person is exposed to those chemicals that person will definitely develop cancer. Smoking causes cancer in many people, but some people smoke for years and don't get cancer.

It depends on the type of cancer. Like skin cancer can be caused by extreme over exposure to the sun. Other types can come from tumors. Try looking on webmd.com, they explain a lot of medical stuff.

Answer 5

Certain things may cause mutations in your DNA, causing cells to rapidly duplicate. Refering to Wikipedia-

"The unregulated growth that characterizes cancer is caused by damage to DNA, resulting in mutations to genes that encode for proteins controlling cell division. Many mutation events may be required to transform a normal cell into a malignant cell. These mutations can be caused by chemicals or physical agents called carcinogens, by close exposure to radioactive materials, or by certain viruses that can insert their DNA into the human genome. Mutations occur spontaneously, or are passed down generations as a result of germ line mutations.

Many forms of cancer are associated with exposure to environmental factors such as tobacco smoke, radiation, alcohol and certain viruses. While some of these can be avoided, there is no known way to entirely avoid the disease."
