Melanoma is the most dangerous kind of skin cancer. the most common type is cutaneous melanoma the development of this disease is presented in the melanocytes. The cause of melanoma is not scientifically discovered but excessive exposure to ultraviolet radiation may increase the risk of getting skin cancer.
Melanoma is a dangerous invasive cancer which starts in melanin producing cells (melanocytes) usually located at the bottom of the skins epidermal layer. Although certain individuals have a genetic propensity for melanoma, it is usually triggered by excessive UV exposure from sunlight or tanning beds (Mayo Clinic, 2016a). At early stages it is relatively easy to treat, however, recurrences are common. At later stages melanoma treatments are less effective since it tends to metastasize and spread easily through the lymphatic system (Mayo Clinic, 2016a).. The root cause of malignant melanoma is due to mutations in the p53 gene protein which invariably leads to further mutations.
There are three primary layers of the skin: the outer layer, the epidermis and the layer beneath, the dermis and the hypodermis. The epidermis is thin, tough and waterproof while protecting the body from outside bacteria invading the body. It also contains keratinocytes which are from the basal layer which is the deepest layer of the skin. The keratinocytes reach up to the epidermis, shed and new ones form again. The dermis is the second layer of the skin and is the thickest. It is made from fibrous and elastic tissues which are made from fibrillin, elastin and collagen to create the strength and flexibility. It also contains sweat and oil glands, nerve endings, blood vessels and hair follicles. Sweat glands help the body cool off during heat
Melanoma is a malignant condition arising from melanocytes in the basal layer of the skin. Melanocytes are the cells that produce melanin, which gives skin its pigmentation and shields the deeper layers of skin from the damaging effects of ultraviolet radiation. When skin is exposed to ultraviolet radiation, melanocytes increase their production of melanin, which generates darker pigmentation of the skin. Ultraviolet radiation stimulates malignant changes within the melanocytes by mutating DNA, stimulating cutaneous growth factors, decreases immune defenses, and promotes species of melanin that cause DNA impairment and suppress apoptosis. The abnormalities caused by ultraviolet radiation in the melanocytes predispose it to
May is Melanoma/Skin Cancer Detection and Prevention Month. Did you know you can use CAPTUREPROOF to create a visual health record of moles and skin discoloration?
Melanoma can be anywhere on your body. Moles, warts, or even a sun burn can lead to melanoma. Melanoma is a form of cancer that begins in melanocytes, cells in the skin that produce the brown color known as melanin. These are the cells that darken when exposed to the sun, a protective response to protect the deeper layers of the skin from the harmful effects of the sun.
Malignant melanoma of the nail apparatus is extremely rare but there have been a few cases reported. It seems that almost half of the population that has been diagnosed with this disease has been misdiagnosed or did not receive the proper treatment to cure the disease. Since the cases are easily misdiagnosed, fatality is usually the outcome for most. Survival rate of this particular disease in recent studies has shown that humans live on average five years after being diagnosed with melanoma of the nail. The disease can affect either the upper or lower nail extremities. The scientist tested seven people, three males and four females, to see how this disease effects each of the patients.
There’s different type of cancers that affects the whole body, and in detail there’s different types of cancers on specific parts of the body. Malignant Melanoma is a form of skin cancer, the most aggressive form of skin cancer. Annually, Melanoma kills more than 10,000 people in the United States. More than 76,000 people are diagnosed every year with this disorder. Once Melanoma is spotted, it’s best to seek treatment, the earlier the better. This form of cancer can spread to other parts of the body if it’s not treated early, and it can become fatal. Moles, brown spots, and growth of either of these things is usually where Melanome can be found, for the most part it can be harmless. Although if you see a growth it’s best to contact your physician
Melanoma is the most dangerous type of skin cancer, it is less common but more serious. In 2012, there was an estimated 996,587 people living with melanoma. In 2015 there were 9,940 deaths with melanoma being the cause. Australia and New Zealand have the highest rates of melanoma in the world. This type of cancer is more common in men than woman. This cancer develops from pigment-containing melanocytes. The majority of melanoma is black or brown and can include skin toned, pink, red, purple, blue, or white. Skin cancer begins in the epidermis which is made up of squamous cells, basal cells, and melanocytes. Melanoma is the disease in which cancer cells form from the melanocytes. It can occur anywhere on the skin, and include a change in the way a mole or
Melanoma is a skin cancer that develops in pigment cells. These pigment cells are called melanocytes. These cells can grow rapidly and can spread throughout the lymphatic system. Early detection is a key factor when dealing with melanoma. The survival rate is determined by how early the cancer is diagnosed. If the cancer is caught at an early stage the survival rate is about 99%, but if it is not and it spreads throughout the lymphatic system, the survival rate drops to 14%. Melanoma is less common than most cancers but is one of the most dangerous cancers. Melanoma is caused by the exposure to ultraviolet from the sun and sunbeds. Sunburns that repeatedly occur can eventually cause the development of Melanoma. Melanoma can start off as just
Skin Cancer is the abnormal division of skin cells which cause tumors in the body. There are 3 types of Skin Cancer: Melanoma, Basal cell carcinoma, and squamous cell carcinoma (Web Md, year). Skin cancer is caused by the exposure of ultraviolet radiation and UV-like factors (Skin Cancer Foundation, 2015). This paper focuses on a specific type of skin cancer called Melanoma.
Melanoma was the major focus of our project. Our initial goal throughout this entire project was to inform the student body about melanoma as well as make an attempt to prevent sun exposure. We planned to find a way to see how much the students at St. Scholastica knew about the dangers involved in being in the sun. We planned to create two surveys and a pamphlet to help find the student body’s knowledge about this dangerous disease. Our group first started off giving out a survey that gave us a base model of how much the students already knew about melanoma as well as sunburn and sun exposure facts. We then proceeded to make a pamphlet that had useful information on it involving when to wear sunscreen, when to be out of the sun, and facts about melanoma. This was then slid under the doors of the residents of Somers hall. We purposely put out this pamphlet prior to going out on spring break in hopes that people would take in this information before they hit the beach. Being that the students got this information before they put their skin in danger of developing skin
What is cancer? This is an important question that will help people to understand the severity of this affliction. Cancer occurs from abnormal cell growth in the human body. When this happens tumors may form. Tumors are a mass of cells that continue to expand. These tumors may be benign. This means they will not spread through the body. Though, the tumors may be malignant which means they may spread to other areas of the body in an invasive manner. These malignant tumors have the potential to cause serious complications and even death. It is these tumors that are cancerous.
One thing that we never want to hear a doctor say to us is that we have a tumor. Tumors are classified into two different classes, malignant or benign. Malignant are cancerous and are life threatening, while benign are not life threatening. Malignant tumors may spread to other parts of the body, while benign tumors stay in the place where they started. When the cells in a tumor are normal, it is benign. When the cells are abnormal and grow uncontrollably, they are cancerous cells. Looking at tumor cells through a microscope, cancer cells appear to have abnormal
