Cancer – Causes

February 28, 2021


There's no one single cause for cancer. Why? Because cancer is not one single disease. Cancer is hundreds of different diseases, depending on where the cancer started. But there are some underlying threats. Tobacco exposure, cigarette smoking, and other forms of tobacco accounts for at least 40% of all cancers by causing DNA damage. Sun exposure is another huge cancer risk. Sun is ultraviolet radiation and is a major cause of skin cancer. Other forms of radiation can also cause cancer. Examples include X-rays, gamma rays or radon. How do these exposures cause cancer? Remember, DNA is the blueprint or the instruction manual that your cells use for normal body function. All of these exposures to either tobacco chemicals or X-rays or sun exposure can cause damage to DNA. This damage in turn can cause cells to grow out of control and a cancer forms.
