Cancer, the most frightening disease that we face today can be prevented. Although it appears “out of the blue” without warning, we have at hand numerous ways to prevent it. So, why not take a stand? Many factors that cause cancer are known and can be removed from daily life. In fact, 90% of cancers are caused by environmental or behavioral factors, according to Huffington Post. Smoking, for example, is the main cause of cancer. If all smokers would give up this vice, the number of deaths would be reduced considerably. In the U. S. at least 25 to 30% of cancers could be avoided if peoples quit smoking. Other major problems are the cases of colon cancer, most often fatal, but can be caught early by colonoscopy and treated. Timely colonoscopy has an essential role in these cases. The same is for cerv buy appesat ical cancer, which can be caught early through Pap tests. In addition, women who want to protect this type of cancer can make its cervical cancer vaccine. Breast cancer can be detected by mammography, and the skin cancer can be prevented by sun exposure with moderation. But tests are not the only thing we can do. A simple change in diet can make the difference between life and death. In 2008, a study from “MD Anderson Cancer Center” in Houston shows that 30 to 35% of cancer deaths are associated with diet. One problem would be, for example, alcohol consumption associated with many cancers. Surely smokers will not throw cigarette packs, fans will not give up alcohol addiction, and addicts will not give up bronze in the solarium or hours spent at the beach, just because they know they can get cancer.
