what causes cancer?

Answer 1

toxins that alter your cells

Answer 2

The exact cause of cancer is not known. Most cancers result from permanent damage to genes or from mutations, which occur either due to internal factors, such as hormones, immune conditions, metabolism, and the digestion of nutrients within cells, or by exposure to environmental or external factors. A chemical or other environmental agent that produces cancer is called a carcinogen.

Overall, environmental factors, defined broadly to include tobacco use, diet, infectious diseases, chemicals, and radiation, are believed to cause between 75 and 80 percent of all cancer cases in the United States. Tobacco use, including cigarettes, cigars, chewing tobacco, and snuff, can cause cancers of the lung, mouth, throat, larynx, bladder, kidney, esophagus, and pancreas. Smoking alone causes one-third of all cancer deaths in the United States. Heavy consumption of alcohol has also been shown to increase the risk of developing cancer of the mouth, pharynx, larynx, esophagus, liver, and breast.

Overweight and obesity are associated with increased risk of cancers of the breast, colon, endometrium, esophagus, kidney, and gallbladder. The following chemicals have been found to cause cancer: coal tars and their derivatives, such as benzene; some hydrocarbons; aniline, a substance used to make dyes; and asbestos. Radiation from a variety of sources, including the ultraviolet light from the sun, is known to lead to skin cancer.

There is some hope though - there's a study out by The Centers for Disease Control and Prevention in Atlanta that says "Vitamin C in it's whole food form prevents cancer of the stomach, esophagus, colon and lung.

Answer 5

we are born with a certain amount of cancer cell in our body. When exposed to cetain things it sometimes tiggers that cell to go into mitosis but instead of dying they countinue to grow and turn into cancer

Answer 6

genetics and environment. to have cancer you must have a gene that has a defect or a gene get defected later in life. if you are born with a defective gene (protooncogene), the environment must provide you with a carcinogen (smoke, asbestos, etc.) to wake the gene up (oncogene).

Answer 7

i believe cancer is all around usand it depends on our cancer cells if we react to them .

Answer 8

It can be cause by tons of things. Genes, smoking, unhealthy environments.

Answer 9

Virus
