¶ … Dietary Fibers on the Risk of Developing Cancer
Cancer is a genetic and complex disease caused mainly due to environmental elements. Carcinogen is a cancer agent that and can be present in water, food, air and in sunlight and chemicals as well. Almost ninety percent of the cancer occurs in epithelia because the epithelia cells cover the human's skin, lines the alimentary and respiratory tracts, and also metabolize ingested carcinogens. Currently, the causes of diseases are changing and infection can cause problems like cancer and cardiovascular diseases. There were more than ten million cancer cases in 1996 globally while six million people died from cancer. Unhealthy lifestyle like smoking cigarettes and adopting modern diet that includes fiber content and high fat is causing increased incidences of cancer in humans (Alison).
Development of Cancer
Cancer cells are different from normal cells and they continue to grow other abnormal cells in the body, forming a tumor. There are different types of tumor like brain tumor, Wilms tumor, breast tumor that causes deteriorating health. Wilms cancer is commonly found in children and happens in the kidneys (ACS, Wilms Tumor ). There is benign brain tumor that can be removed and does not grow back and there is malignant brain tumor that is life threatening (USDHHS).
Cancer cells grow and invade other tissues. Growing and invading causes the cell to become a cancer cell because the DNA of the person gets damaged. Every cell contains DNA which can be repaired...
However, the cell does not die and continues making new cells not needed by the body. Every cell created from cancer cell has a damaged DNA which can be inherited by the future generations (ACS, Wilms Tumor ). Every gene has a DNA and abnormal changes in those DNAs are called mutations. Mutations affect the cells in different ways either by stopping protein development or by making more protein than required by the human body. Mutation also causes normal cells to become cancer cells (ACS).
Proto-Oncogenes and Tumor-Suppressors
Proto Oncogenes help the cells to grow normally, but when mutations occur, the oncogenes become abnormal causing uncontrollable growth, leading to cancer. Some cancers are caused by the mutations that are inherited and turn on the oncogene. Slowing down of cell division is done through tumor suppressor genes; they also repair DNA damages and send the message to the cell when it's time to die. Improper functioning of these genes causes cancer. Oncogenes occur from the activation of the genes while tumor suppressor occurs from deactivation of the genes (ACS).
The effects of dietary fat
Diet related elements cause about thirty percent of cancer and obesity increases cancer risks in kidney, endometrium, breast, colorectal and esophagus. Alcohol is the cause of liver, esophagus, larynx, pharynx and oral cavity cancer. A lot of hypotheses for the dietary effects of cancer have been found from investigation…

(Brussels sprouts, kohlrabi and cauliflower); (6) Consume alcoholic beverages only moderately; and (7) Only moderately consume salt-cured, smoked and nitrate cured foods. (American Cancer Society, 1984, pp. 122-123) What little was understood about nutrition as it relates to cancer rates is summed up in the following specific food categories by the American Cancer Society in its 1984 report: Food
LOW FAT DIETS ARE HEALTHIER THAN THE ATKIN'S DIET The philosophy behind so-called "low carb" diets such as the Atkins Diet is that obesity is primarily the result consuming too many carbohydrates, and that the traditional medical focus on lowering fat intake is partly to blame for obesity in the United States. The theory underlying the Atkins Diet philosophy is that carbohydrate consumption stimulates elevated insulin levels in accordance with their
Tobacco use or cigarette smoking is also linked to the development of colorectal cancers most especially after more than 35 years of smoking. but, there is no biological explanation for this link. Colorectal cancer is often incidentally found in screening procedures and may be completely asymptomatic. But approximately half of patients with colorectal carcinoma experience abdominal pain, this is the most common symptom. About 35% of patients have altered bowel
Mr. Coach is a 51-year-old white male who was referred by a primary physician because of his elevated blood pressure during a routine screening. Mr. Coach has had a history of heart issues, including an abnormal heartbeat in 2012 for which he underwent a medical procedure. Although Mr. Coach does not smoke and he exercises regularly, he has a family history of hypertension and other risk factors that make it
Breast Cancer in Malaysia Breast cancer has turned out to be one of the most common cancers in women in almost every part of the world. Nonetheless, there is a noticeable geographical difference in the incidence and also the stage of presentation. It has ben documented to be uppermost in North Europe and North America, in-between in Mediterranean nations and South America, and not high at all in Asia and Africa
Lifestyle Factors Inducing Cancers Course code Cancer is one of the leading international causes of morbidity and mortality. Lifestyle factors that contribute to causing cancer have been widely studied in recent years. Summarizing relevant studies, lifestyle factors identified include smoking, alcohol consumption, diet, weight management, physical activity, and environmental exposure. These studies use a variety of methodologies to determine the link between the lifestyle factor and risk of cancer. Issues with the
