Cancer Development: Cancer is one of the most endangering diseases that affects even young people. Cancers is a multistage process that may take a long time before clinical signs are obvious. Cancerous cells development is associated with the exposure of the DNA to harmful molecules which originate within the body or from outside of it. There are three main stages involved in the formation of cancer cells:

-- a mutation of DNA, without undergoing DNA repair by enzymes or it undergoes faulty DNA repair.

-- promotion is the second phase. It involves an uncontrolled growth and proliferation of changed cells. Such cells will loose their normal features and functions and will only reproduce.

-- metastasis is the third step and refers to the invasion of cancerous cells into tissues and organs. It also involves the migration of cancerous cells to various tissues through transport or circulatory systems.

The main causes of cancer are not known yet. Nonetheless, scientists have discovered that exposure to man-made environmental contaminants and toxins that occur in food and atmosphere may be a cause. For example, aflatoxin is a by-product of mold in peanut butter, isocyanate is found in brown mustard, nistrosamines from cooked bacon and benzo(a)pyrenes are found in barbecued foods.

Additionally, excessive consumption of alcohol, tobacco, salt or fat are susceptible to causing cancer, so people should have a healthy diet and lifestyle. Fortunately, research on diet shows that there are aliments that can help us prevent cancer and the main recommendation for individuals is to eat more fruits and vegetables, cereals, fish and drink natural juices.

Maintaining a normal body weight is also important, so people should avoid being underweight or overweight. They should choose mainly foods of plant origin, eat various fruits and vegetables, meat limit should be less than 80 grams (3 ounces) and they should also limit consumption of fatty foods, especially those of animal origin.

Moreover, perishable food should be stored properly to prevent fungal contamination, salt consumption should also be limited and meat cooking temperature has to be low. To prevent cancer, people shouldn’t smoke, drink too much alcohol and they also have to inform on additives found in food to avoid them. If many people would follow these recommendations, it won’t be necessary to take dietary supplements to reduce cancer risk. There are reliable scientific explanations behind all these dietary changes and their positive role in preventing cancer and it seems that dietary composition has more influence on cancer than food additives, pollution, chemicals, as well as other risk factors.
