Cancer is a type of disease where abnormal cells called cancer cells divide in a process called Mitosis, however, without control and are able to invade other tissues in the body, spreading. The Stages of Cancer are as so:
Stage #0: This is highly likely to be able to cure. The cells are located in one place and have not spread around yet
Stage #1: This is a small type of cancer, and as the cancer cells have spread into some neighbouring tissues, it is an early stage, and the cells have not grown too deeply
Stage #3: This is where the cancer cells have grown and spread to nearby tissues, but not to the other parts of the body
Stage #4: This stage means the cancer cells have spread to other parts of the body
A tumor is a lump of cancer cells surrounded by normal cells. If it is not treated, it can spread to normal tissues nearby, cause pressure on other body structures, and spread to the other parts of the body. There are 2 types of tumor, which are: benign and malignant tumor. Benign tumor is a type of tumor which is not made up of cancer cells, grow gradually, don’t spread to other parts of the body, and usually have a wall of normal cells surrounding them. Malignant tumor is a type of tumor where the cells are cancer cells, which grow faster, spread and destroy nearby tissues and spread to the other parts of the body. For Cancer, there are more than 200 types, but in a more general tone, there are 5 major categories of cancer, Carcinoma, Sarcoma, Leukaemia, Lymphoma and Myeloma, and Central Nervous System Cancer. Carcinoma Cancer is a type of cancer that begins in the skin or tissues that cover or line organs. Sarcoma Cancer is a type of cancer that begins in the bone, cartilage, fat, muscle, blood vessels or other connecting or supporting tissue. Leukaemia is type of cancer which begins in tissues that produce blood and causes a number of abnormal cells to enter and produce without control. Lymphoma and Myeloma Cancers are cancer that begin in the cells of the immune system. Central Nervous System Cancer is a type of cancer that begins in the tissues of the brain and spinal cord. There are many treatments for Cancers, although no definite solutions yet. The main treatments are surgery and therapy. Surgery can be to diagnose cancer, to treat cancer, and to reduce the risk of the spreading of cancer cells. Therapies, although can’t remove the problem definitely, can have a chance to remove it, or at least reduce the cancer. 2 examples of therapy is Chemotherapy and Radiotherapy. Chemotherapy, which mean drug treatment, is a drug that kills cancer cells. Radiotherapy uses x-rays, by destroying the cancer cells in the area by damaging the DNA in the cells. There are a lot more, like Biological, Hormone Therapy and more. As I stated before, there is no absolute solution for cancer, but as technology and the knowledge of science and medicine increases, hopefully in the future, there will be.
