Cancer of the body is currently among the leading cause of death in the 21St century and it can arise from any cell of the body. More than half a million people die yearly from cancer with a greater burden load on the disability caused by advance cancer and the total cost of treatment. Leading cause of cancer death includes breast cancer, lung cancer, cervical cancer, cancer of the liver and the kidney, colorectal cancer, leukemias and lymphomas.
Cancers are abnormal mass of tissue arising from any organ or structure of the body, with a growth pattern that is uncoordinated and in excess when compared to that of the surrounding normal tissues leading to a mass of cells that is autonomous, purposeless with the ability to infiltrate normal tissues locally and the ability to metastasize to organs far from the organ/ site of origin the cancer. The ability of cancer cells to affect distant organs accounts for its aggressive nature. This cause death when vital organs like the brain heart, lungs, liver and the bones are affected. Cancer cells are carried via the blood stream or the lymphatic vessels which drains the site of the cancer.
Cancer cells prey on its host for the competing with the normal cells of the body for nutrient and space causing death of normal cells or crowding of the normal cells as seen in cancer of the bone marrow. These cells are highly autonomous with improved blood supply to them and the cancer may flourish in a patient who is wasting away.
Cancer as a disease to a greater extent can be prevented as most causes or risk factors associated with cancer development are manmade agents causing mutations in the cells leading to cancer formation. Below are useful tips that can help you reduce the risk of developing cancer.
