Even though Chemotherapy is used to kill all the cancer’s cells, it also kills the red and white cells in process, giving side effects like, bleeding (nose bleeds) , hair loss, and vomiting (Patlak 21). In cases of only having a small stage of NHL or when Chemotherapy is out of the picture due to the damage Chemo does to the heart, Radiation therapy is a second choice. In some cases, however, both Chemo and Radiation therapy is used simultaneously. Radiation therapy is a high energy x-ray that is used to damage cancer cells and stop them from growing. With NHL doctors often not only aim the radiation to the one site but to the other lymph nodes in the region to make sure the cancer is not hiding in another node.
How fast the cancer cells are dividing play a role in how much time you have to treat the disease. The thickness of the tumor and where it is in the body can weigh on the correct type of treatment to be used. If there is bleeding or an ulcer at the site this is also a factor. The amount of spots the cancer has spread in the body. Also, the patients general health at the time can effect the right treatment options.
Malfunctioning patch leads to defective embryonic development and many types of skin cancer. Apoptosis is controlled cell death; patched is responsible for that too. When this gene does not work tissue structure is not maintained, embryo's toes and fingers do not take shape, and skin cancer can grow unchecked. Hedgehog, the gene that turns on the patched gene, can also lead to skin cancer when it does not function. The gene product of hedgehog is a protein that rests on the cell membrane and sends signals to the nucleus of the cell.
Jacky Huang Medical Report 10/18/11 1)Cause of Deficiency Cancer is a class of diseases characterized by out-of-control cell growth, and lung cancer occurs when this uncontrolled cell growth begins in one or both lungs. Rather than developing into healthy, normal lung tissue, these abnormal cells continue dividing and form lumps or masses of tissue called tumors. Tumors interfere with the main function of the lung, which is to provide the bloodstream with oxygen to be carried to the entire body. Most lung cancers are the result of inhaling carcinogenic substances. Carcinogens are a class of substances that are directly responsible for damaging DNA, promoting or aiding cancer.
These mistakes result in mutation leading to loss or inappropriate expression of affected genes. Studies indicate that genetic alterations in the P53 tumor suppressor gene play an important role in the development of skin cancer. The p53 gene is also involved in apoptosis (programmed cell death), and it has been proposed that p53 serves as a “guardian of the genome” by aiding in DNA repair or by going through apoptosis to elimated cells with excessive DNA damage. Unrepaired damage in the p53 gene are transformed into mutations thereby initiating the process of carcinogenesis. Following repeated exposures to UV, keratinocytes (sunburn cells) carrying
The Immune system normally functions to protect against foreign invaders by sending out certain cells that attack and destroy the ailment affecting your body, like an infection or a cold. But with lupus the immune system becomes hyperactive that the immune system begins attacking the body itself. What happens is the immune system sends out what is called B cells to attack an infection, but in Lupus the B cells live longer then they should. These B cells produce an antibody,
Nancy Terry Unit 4 Case Study 2 There are many things that can contribute to he risk of having skin cancer. Our genes play a huge role in our skin, but the can also influence the risk of developing skin cancer. Genetic mutations account for forty percent of all occurrences of inherited skin cancers. Research shows that specific mutations in certain genes like POT1 were likely to develop melanoma, which is a type of skin cancer. This particularly mutation deactivates POT1, which protects the ends of chromosomes.
Unit Four Case Study Two: Skin Cancer Brittany Drake ITT Technical Institute Unit Four Case Study Two: Skin Cancer Genetic mutations as well as exposure to ultraviolet light are two components in developing skin cancer. Skin Cancer is the abnormal growth of cells as a result of mistakes made by stem cells when copying a cell’s DNA. Genetic factors such as ones eye color, hair color and color of their skin also play a role in ones susceptibility in getting skin cancer as well as the environment in which one resides. Skin Cancer Sixty five percent of cancers start when one or more genes inside of a cell are mutated. The greater number of stem cells present in specific types of tissues as well as how often they divide means the greater chance one has in developing skin
The cells also lose the ability to die, as normal cells would. The accumulating abnormal thyroid cells form a tumor. The abnormal cells can invade nearby tissue
The health risk assessment that I chose to see my risk level was for lung cancer. I believed I would have a high risk for lung cancer because my past smoking habits and family and loved ones who smoke. I was also exposed to asbestos when I served in the United States Army from the old buildings which I thought would raise my risk level. The risk assessment made it clear to me that I need to have screening tests completed. Cancer is a group of diseases that all have out of control growth of cells in common.
