Breast cancer genetic abnormality

Cancer is a term commonly used for diseases in which abnormal cells divide uncontrollably and invade other tissues. Cancer cells can spread to other parts of the body through the blood and lymph systems. Cancer is not just one disease but many diseases. There are more than 100 different t3 pes of cancer, hence, the complexity of cancer treatment. It is the second leading cause of death worldwide after heart disease, and its risk and incidence increase with patient age (www. cancer.gov). In addition to genetic factors, enviromnental and nutritional factors play a main role in cancer etiology. In westernized countries, breast, prostate, and colon-rectum cancers predominate because diets are usually rich in animal-source foods and refined carbohydrates and deficient in plant foods. Conversely, in developing countries, where diets are largely based on cereal/starchy foods, esophageal, stomach, and liver cancers are more incident [127].
