Cancer and Its Causes, Types, and Warning Signs

There are over 200 diseases that can be called cancer. They have different causes, happen in different tissues, develop in different ways and for different reasons, and demand a variety of treatments. They all have one fatal element in common. In every case normal cells have gone wild and lost their normal growth and development.The 3 classifications of cancer:Cancer is classified in 3 stages. The cancer in the epithelial tissue (covering or lining of tissue) are called carcinomas. The 2nd class of malignant tumors is the sarcomas. They originate in connective tissue such as bone and muscles. The 3rd class of cancer is leukemia and the lymphomas. They are diseases of the blood forming organs and the lymphatic system. They are not tumors and spread in a different way.Stages of cancer:Initial stages of cancer may start with just one or a few cells in the body that undergo a change and become malignant or cancerous. The cells divide and reproduce themselves. Most cancer arises on the surface of tissue such as skin, uterus lining, mouth, stomach, bowel, bladder, bronchial tube in the lungs, or inside a duct in the breast or prostate gland. The cancer eventually grows from a microscopic clump to a visible mass. It then invades underlying tissue. As long as cells remain in one mass, the cancer is localized.Later stages of cancer start in a process called metastasis where some of the cancer cells split off and go into the lymph channels or bloodstream to other parts of the body. If the disease is not arrested it will rapidly invade other parts of the body. Death is usually a more certain result then. Some people respond to radiation therapy and some do not. About one half of the known types of cancer are incurable at almost any stage. Of all or any cancer it is imperative to diagnose and treat it as soon as possible.Causes of cancer:Cancer can be caused by factors in our environment. These factors include a large number of chemical agents such as tobacco, tobacco smoke, asbestos fibers, and other occupational hazards. Other causes are X Ray radiation, nuclear bombs, sunlight, injury or repeated irritation, metal or plastic implants, flaws in the body’s immune system, genetic mistakes, and some scientists believe viruses also.Major types of cancer:- Lung Cancer – Kills more Americans than any other cancer.
