GENETIC MUTATIONS THAT CAUSE SKIN CANCER 2 Cancer begins when one or more genes change from their normal form. This either creates an abnormal protein or no protein at all‚ both of which cause mutated cells to multiply uncontrollably. (Association‚ 2011) Melanoma can either be caused by inherited genes or defects that are caused from environmental factors‚ such as exposure to too much sun. However‚ according to the Centre for Genetics Education‚ all cancers can be considered genetic

Type of cancer. Melanoma is a skin cancer that originates in the melanocytes‚ a type of cell that makes up the skin. Skin is formed by three layers: epidermis‚ dermis and subcutaneous tissue. Melanocytes‚ together with keratinocytes‚ are part of the epidermis and are responsible for producing melanin‚ a pigment that protects against the damaging effects of sunlight. The formation of melanin - melanogenesis is a biochemical process carried out by melanocytes and is affected by several hormones: α-melanocyte-stimulating

of skin cancer is known as melanoma. It originates in the skin cells that make melanin‚ which gives skin its pigment and protects the deeper layers of skin from the sun’s damaging ultraviolet (UV) rays. These cells are called melanocytes. The melanocytes produce more melanin and cause the skin to tan when time is spent in the sunlight. The melanocytes may start to grow abnormally and can become cancerous if the skin obtains too much ultraviolet light. This condition is commonly known as skin cancer

Compared to majority of the organ systems‚ the integumentary system is one of the largest organ systems that play an important role in protection and maintenance of body temperature and fluids (Cancer Treatment Center of America‚ 2007). According to the video‚ the skin is composed of three layers with each layer having different types of cells. The first layer is the Epidermis which

Unit 4. Case Study 2: Skin Cancer Cancer and Genetics When it comes down to it‚ all cancer is genetic. It’s a result of mutations or changes in the DNA sequence of our genes. Genes can be looked at as a set of instructions that tell our cells what to do. Our DNA sequence “spells out” our genes into letters. Mutations are basically errors in the “spelling” of our DNA codes. Most mutations‚ if they’re minor‚ can be fixed by our own body’s cells. Problems arise when these mutated or damaged
