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
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.
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
One method of killing cancerous cells is by using radiation therapy. There are many different types of radiation and many different ways to administer the treatments. Radiation therapy is the use of ionizing radiation to kill cells and shrink tumors (Radiation Therapy for Cancer). This technique does kill the cancer cells but also harms the surrounding normal tissues that are in the way. There are many bad side effects, short and long term, associated with radiation treatments.
Jodie-leigh minett Outline and evaluate the relationship between stress and the immune system. The immune system is a collection of billions of cells that travel through the bloodstream. They move in and out of tissues and organs, defending the body against foreign bodies (antigens), such as bacteria, viruses and cancerous cells. There are two types of lymphocytes: B cells- produce antibodies which are released into the fluid surrounding the body’s cells to destroy the invading viruses and bacteria. T cells - if the invader gets inside a cell, these (T cells) lock on to the infected cell, multiply and destroy it.
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.
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.

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.
Breast Cancer Did you know what the second-leading cancer killer of women is in the United States? Every year millions of women are affected by breast cancer. Thanks to screening, breast cancer can now be detected early and has even helped cure women from the disease. The thought about this disease is not going to help you; it is time for you to get the facts straight. The most common questions that are related to breast cancer are: What exactly is breast cancer?
