Biology project - Essay ExampleThe moment this happen, there is no death of cell when they should later, sore cells form regardless of whether the body needs them or not. The extra cells which formed can develop into a mass of tissue that is popularly cognize as Tumor. Tumor ( crabmeat Council, 1 6) may exist as lump it can be malignant (cancerous) or benign (not cancerous).Cancer cells that turn larger than pins read/write head typically has their own blood vessel. Occasionally, they go away from the primary location of the cancer either by the region of the blood or lymph vessels and later get down to well over other organs of the body. At the new site, they continue to grow to form another tumor (Cancer Council, 1 7).Specific type of cancer is Lymphoma. Lymphoma (Michigan Cancer Consortium, 11) that affects white blood cells known as lymphocytes. These are immune cells which are basically working to protect the body from getting. In lymphoma, malignant cells are formed and may accumulate to develop into tumors. Later it enlarge making lymph nodes seemed swollen while other cancer cells spread to other parts of the lymphatic system resembling bone marrow, spleen, climb, or mucosal linings of the stomach.Common symptoms caused by this illness are Drenching night sweats, Persistent fevers or chills, Persistent skin rashes and itching, Unexplained weight loss, Unexplained fatigue, Painless swelling of lymph node (Kuppers, 234). Lymphoma is the most commonly existing blood cancer, and in fact, it is the third common childishness cancer. Since the 1970s, the incidence rate of non-Hodgkins Lymphoma (NHL) with each year has increased 4% annually (Karl, 1par Your Name Here 22. Research the mechanism of that peculiar(a) cancer i.e. what enzymes, proteins are involved).Basically, lymphomas are cancers which begin by the malignant transformation of a WBC lymphocyte in the areas of the lymphatic system. Many lymphomas are known to be due to specific genetic m utations.Lymphocytes recognize pathogens (infections and abnormal cells) and destroy them. There are 2 major subtypes of lymphocytes B lymphocytes and T lymphocytes, also referred to as B cells and T cells. B lymphocytes are much affected in individuals with lymphoma Note that the former produce antibodies. When a cancer causing agent like a virus is detected, the T cells, are immediately activated, which in turn kill pathogens directly. Part of the mechanisms of T cells are the immune system control (controlling all over activity or under activity). B and T lymphocytes are the ones fighting off an invader. Cancer occurs the moment normal cells undergo a transition whereby they grow at the same time multiply uncontrollably. Consequently, as the cells continue to multiply, formation of mass or tumor may also be formed. Tumors usually invade tissue spaces and areas surrounding it if lymphomas are no controlled, it can progress on and/or invade the neighboring tissues or distant organ s (emedicinehealth.com 7). Tyrosine (protein) kinase and the phosphoinositide
