The Deadly Disease
Many people have suffered from an illness,virus, or disease. A well known disease that people are familiar with is cancer. Cancer is when a human body cell breaks down and cancer cells begins to form, grow, and divide. The cancer cells do not experience death. The main question about the disease is what causes cancer. Cancer is caused by the environment, poor diet, alcohol and smoking consumption.
80-90% of cancer is caused by the environment. The chemicals in the environment are toxic substances which produce cancer. The environment consists of many factors that lead to cancer such as the sun and the radiation. Being exposed to the sun too much could damage the skin and the cells leading to skin cancer. “Over the past three decades, more people have had skin cancer than all other cancers combined.” (Skin Cancer Foundation) “Ultraviolet rays often have enough energy to damage the DNA in cells which means they can cause cancer.” (American Cancer Society) The radiation from the sun leads to cancer by damaging the skin. “Diets that are low in vegetables, fruits, and whole grains, and high in processed or red meats are linked with a number of cancers.” (CA Cancer J Clin 56) Statistics show 30-40% of cancer is caused by a poor diet. Also “being overweight or obese is known to increase the risks of many types of cancer.” (Cancer.Org) Four in ten citizens are diagnosed of cancer because of their unhealthy diet. Alcohol and smoking consumption can cause cancer. “2 to 4 percent of all cancer cases thought to be caused either directly or indirectly by alcohol.” (American Cancer Society) Alcohol contains a chemical called acetaldehyde. Acetaldehyde can cause cancer by damaging the DNA and stopping the cells to grow. Eighty seven percent of smokers in the US suffers from cancer. “Smoking is the leading cause of cancer and death from cancer.”(Department of Health and Human Services) Smoking tobacco contains chemicals that damages DNA and leads to cancer by making the cancer cells to grow. Cancer is a serious disease that people are familiar with. It is important to recognize how it deadly this illness can be. It is also important to know the aspects that leads to cancer which are causes of the environment, poor diet, and alcohol and smoking consumption. |
