Melanoma is the most dangerous of skin cancers. It is a skin cancer that begins with an uncontrolled growth of cells that damages tissues. It develops when unrepaired DNA damages the skin cells, triggers mutations and causes the skin cells to multiply and form malignant tumors. The tumors originate in the pigment that produces melanocytes in the base layer of the epidermis. Melanoma is not always cancer of the skin.
Neuro Fiber Mitosis A genetic disorder is a disease that is caused by a different form of a gene called a variation, or a mutation. Many diseases have a genetic aspect. Some, including many cancers, which are caused by a mutation in a gene or group of genes in a person's cells. These mutations can occur randomly or because of an environmental exposure such as cigarette smoke. Genetic Disorders like von Recklinghausen disease or more commonly known, as neuro fiber mitosis are a group of three genetically disorders that cause tumors to grow in the nervous system.
Unit 4 Case study 2 It is known that overexposure to large amounts of UV light/ radiation can be harmful to the body and can cause skin cancer to occur. However, another possible cause has been brought to light. What if the cause of this cancer were more than skin deep? What if it were already present from the time of birth? Cancer is a multifactorial disease resulting from complex interactions between environmental and genetic factors.
Cancer and Non-Hodgkin Lymphoma Cancer, when someone is diagnosed or knows someone who is diagnosed a wide range of thoughts and emotions race through their mind. There are many different types of cancers that can afflict almost anywhere in the body. Still many ask what exactly is cancer and what makes it so dangerous. Cancer is in its most basic form is an uncontrolled growth of a collection of cells. These cells due to the uncontrolled growth become dysfunctional and cause a myriad of problems inside the body.
Scientists used the multilayer defenses, immunotherapy, and research to help with the cure of Shirley’s melanoma. The problem with cancer is that it is your own body’s cells attacking each other. The other problem is preventing relapses and catching it before it
Leukemias I. Definition: Leukemia appears to be a clonal disease resulting from the abnormal uncontrolled proliferation of a single stem cell from which a new clone of cells develops. For some unknown reason, these abnormal cells have a selective growth advantage over normal cells. Present data indicate that these cells are functionally different and biochemically abnormal. II.
Cancer cells crowd out and destroy nearby healthy cells, forming growths called malignant tumors. Melanoma that spreads to vital organs like the brain or liver can be life-threatening. “Melanoma can appear on normal skin, or it may begin as a mole or other area that has changed in appearance. Some moles can present at birth may develop into melanomas.” (Medline Plus para. 4) There are four major types of melanoma skin cancer, Superficial spreading melanoma, Nodular melanoma, Lentigo maligna melanoma, and Acral lentiginous melanoma.
The first random damage theory of aging is called DNA Damage. DNA damage assists in explaining how physical aging and eventual death are visible signs of DNA damage. When more and more DNA mistakes begin to accumulate, then faultier proteins are produced thus meaning more cells will malfunction and die. When enough cells are lost from the body then death occurs. Another random damage theory of aging is called free radical damage.
When people have lactose intolerance, it means that the lactase enzyme has changed shape during mutation therefore it is unable to synthesise the substrate therefore it will not be digested correctly. There can also be competitive inhibitors in which they bind to the allosteric site of the enzyme meaning that the substrate cannot bind to the enzyme. If the competitive inhibitor was not the same shape then the inhibitor would not work. Competitive inhibitors are often used in medicine to prevent synapses being passed on. Another example would be in vaccines where they inject dormant cells into the body for your antibodies to produce an active site that would be able to destroy that antigen.
Cancer may be caused by a number of factors that include inheriting a gene that give an individual a particular type of cancer, contracting a virus that causes a specific form of cancer, being exposed to certain types of radiation and particular chemicals that cause cancer. Changes in the immune system and exposure to certain environmental factors can also cause cancer. The earlier cancer is treated, the greater the chance for a cure. The cancers for which excellent
