ated with drugs to kill any cancer cells and then are frozen until they are transplanted back into the patient. This procedure may be done alone or with an autologous bone marrow transplant. There is a greater chance for recovery if the doctor chooses a hospital that does more than five bone marrow transplantations per year. Lung Cancer is the most common cause of cancer death in the United States; it is responsible for about 160,000 deaths each year. For over 40 years, breast cancer was the major cause of death in women, but since 1987, lung cancer has surpasses breast cancer as a killer of women. Lung Cancer is the uncontrolled growth of abnormal cells in the lung. Normal lung tissue is made up of cells that are programmed by genes to create lung tissue in a certain shape and to perform functions. Lung cancer forms when the genetic material responsible for the production of lung cells is damaged. Repeated exposure to carcinogens such as tobacco smoke may cause damage in the lung cells. While tobacco, is the leading cause of lung cancer, some other carcinogens linked to lung cancer includes radon and asbestos.Researches have discovered that there are some genes that are not replicated in the lung cells of people who smoke. This is known as gene deletion. It is especially prevalent in youth who smoke. Research indicates that young smokers are more susceptible to genetic damage in their lungs from tobacco smoke. Some genes are known as tumor suppressers. Their job is to keep abnormal cells form growing and forming tumors. Researchers have determined that a tumor suppresser gene known as p53 is almost always defective in cases of small cell lung cancer, and in approximately half of nonsmall cell lung cancer cases. Because of the defect in the gene, it does not stop the reproduction of tumor cells as it should. Some people inherit genes from their parents that are more resistant to damage and cancer than others. Those whose genes do ...
