In 2006, Harvard Men’s Health Watch stated that “About 1.4 million Americans will be diagnosed with cancer this year, and some 560,000 will die from the disease” (Exercise and Malignancy 5). Many individuals and families have fought the battle of cancer for a number of years. There is not yet a perfect cure for this number one deadliest disease, and it is unknown how long it will take to find one. While many risk factors of developing cancer cannot be changed such as genetics, environmental carcinogens (substances that cause cancer), or a certain number of hormones, fortunately, there are several studies that show there are ways to somewhat reduce the risk of cancer. It is not possible to be immune, but by following a nutritional diet and developing a physically active lifestyle, it is possible to reduce the risk of cancer immensely.
Many substances or factors cause cancer, but any type of cancer develops the same way. Normally, the cells that make up the body grow and then divide. Eventually these cells die and new cells are produced. Cancer results from a mutation that has altered the DNA that make up a cell. These mutations affect certain cancer genes that are in the body, tumor suppressors and oncogenes. Tumor suppressors tell the cell to slow down cell division which prevents the cells from over-dividing. Cancer mutations destroy these genes, causing cells to divide uncontrollably. Mutations also affect an oncogene, which tells the cell when to grow. These mutations keep oncogenes in an “active state”, causing an overproduction of cells (Gibbs 60). The body does not need these extra cells and may become a mass, or a tumor. Fortunately, not all tumors become cancer. A tumor that is not cancerous is called a be...

Eating Ourselves to Death Essay - In the words of French author and social critic Francoise La Rochefoucauld, “To eat is a necessity, but to eat intelligently is an art” (“Food Quotes” 1). Perhaps this is why science seems to have failed us in defining what exactly intelligent eating is. If indeed it is an art, it would be far more fruitful to ask an artist (in this case a chef or a gourmand) what constitutes a healthy diet. But this is the 21st century, and we look to dieticians and nutritionists to tell us what to eat. The problem as I see it is they can’t seem to agree on anything or make up their minds for any length of time....   [tags: Nutrition]
