Melanoma
Melanoma is the most dangerous of skin cancer. Melanoma is complicated from how it happens, the signs and symptoms, causes, risk factors and treatment. There are so many types of cancers, but Melanoma is a cancer that you do not hear of as often.
Melanoma starts in the melanocytes. Melanocytes are the cells that make the pigment melanin according to (www.skincancer.org). Cancerous growths can develop from UV lights and the sun. A source of UV lights would be tanning bed. These sources caused cells to trigger mutation. The trigger mutations cause genetic defects. Genetic defects leads to skin cell multiply and form malignant tumors.
The tumors can be multiply colors such as black, brown, pink, red, purple, blue and white according to (www.skincancer.org). “These tumors orginate in the pigment producing melanocytes in the basal layer of the epidermis”. Stated by (www.skincancer.org). If the tumors can be recognized early they are more likely to be treatable. Some people are not as lucky and it spreads throughout the body, and this makes it harder to treat the cancer. According to (www.skincancer.org) “120,000 new cases of melanoma in the United States are diagnosed in a year. In the year 2010 about 68,130 invasive melanomas, with about 38,870 in males and 29,260 in women.”
Melanoma develops in areas that are more exposed to the sun. Melanoma can also occur in areas such as feet, palms of your hands and fingernail beds. This is less likely, but most often occurs in people with darker skin. (www.mayoclinic.org). One of the first signs of melanoma is a change in an existing mole or sometime of unusual growth on your skin. (www.skincancer.org) explains the ABCDE signs of a mole. A is for Asymmetry. The way to determine thi...

...is, for the physician will perform surgery to remove the cancer. Stage 1 will also need surgery, may also need sentinel lymph biopsy and interferon.
Stage 2 will need surgery, sentinel lymph node biopsy and interferon after surgery. Patient may also be considered for a clinical trial. Stage 3 patient will receive surgery, interferon, possibly radiation and or chemotherapy. Immunotherapy may also be performed.
Stage 4 consists of surgery, radiation, immunotherapy, chemotherapy. Patient may also be considered for a clinical trial. Patient may decide to stop treatment.
Melanoma is a serious cancer that needs to be monitored. Melanoma is complicated from how it happens, the signs and symptoms, causes, risk factors and treatment. Knowing the signs and symptoms can help detect the melanoma early to help prevent the cancer spreading and treatment to be started.
Basil Cell Carcinoma begins in the deepest layer of the epidermis of the skin. The epidermis is known as the top layer of the skin. The skin is composed of 3 layers, the epidermis, dermis and subcutaneous tissue. The basal layer which is part of the epidermis, there are cells called melanocytes, which produce a black pigment called melanin. Melanin is what protects your skin from over exposure to the sun’s ultraviolet rays. Over exposure of sunlight can reduce the melanin’s ability to absorb the sunlight and damage the skin. (2)
Melanocytes, embryologically derived from the neural crest, are distributed in the epidermis and thus are found throughout the skin. They produce a brown pigment known as melanin and are responsible for racial variation in skin color and also the color of moles. Malignant degeneration of the melanocyte gives rise to the tumor, melanoma, of which there are four subtypes. These are: superficial spreading, nodular, lentigo maligna, and acral lentiginous melanomas, accounting for 70%, 15% to 30%, 4% to 10%, and 2% to 8% of cases, respectively. Malignant melanoma may develop anywhere on the body. In men, it is most common on the trunk. In women, it is most common on the back or legs. The subtype also may influence where the tumor develops, lentigo melanoma is more common on the face while acral lentiginous melanoma is more common on the palms of the hand, soles of the feet, or in the nail beds.
In melanoma some common signs and symptoms are the doctor may notice an abnormal area in the skin that may look unusual. A mole, sore, lump, or growth on the skin can be a sign of melanoma. A sore or growth that bleeds, or changes in skin coloring may also be a sign of skin cancer. Your doctor may run several test to detect if melanoma is...
What is skin cancer ? first, Skin is the largest organ of the body . it gives our body protection from harms, injuries and infections. It also organize the body temperature and dispose of waste substances through the glands . out layer of the skin is called the epidermis and the layer underneath is known as the dermis . Skin cancer is type of disease where malignant cancer cells are to be found the outer layer of a person's skin and is the uncontrolled development of the irregular skin cells .It occurs when unrepaired DNA damage to skin cells caused by ultraviolet radiation from sunlight or genetic defects, that lead the skin cells to duplicate rapidly and form malignant tumors. there are three main types of skin cancer which are basal
Because of advancements in technology and funding survival rates have increased in each patient and quality of life due to better chemotherapy and radio therapy drugs are helping millions of survivors round the world to lead a generally normal life without the risk of the cancer returning.
The color, size and shape of the pigment spots may change with time. This needs a serious treatment and may otherwise become cancerous moles.
The first sign of melanoma is often a change in the size, shape, or color of an existing mole or the appearance of a new mole. Men most commonly develop melanoma on the trunk, particularly the back, and women on the legs or arms. Melanoma develops in a manner similar to other cancer types. A cell's DNA genes, which control cell division and reproduction, become damaged. The damaged genes cause the cell to divide and grow without control or order, eventually becoming a malignant tumor.
The University of Texas MD Anderson Cancer Center states the disease is divided into two major types namely acute and chronic. The acute types of the disease are those that progress quickly and involve an overgrowth of very immature blood cells. This becomes life threatening because very few mature cells mean that the body loses its ability to prevent infection, anemia and bleeding disorders. A diagnosis of the acute type is given when the immature cells found account for 20% or more of the blood cells produced. The chronic type progress slowly and involves an overgrowth of mature blood cells. In contract to the acute type people affect by this type usually h...
Basal and squamous cell skin cancer are the most common forms of skin cancer. Multiple studies have shown that these cancers are almost always connected to large amounts of sun exposure. This can come from things like outdoor sports, performing something outdoors with little coverage from clothing, and getting multiple severe sunburns. You can see signs of skin cancer inside and outside of your body. Rough, thick, dry skin patches are common symptoms, but things
Skin cancer is the most common type of cancer in the United States. There are two different types of skin cancers: Melanomas and non-melanomas. To understand both of these terms a little better you need to be aware that your skin is divided up into 3 layers: the epidermis, dermis, and subcutis. The top layer, the epidermis, is very thin and serves to protect the deeper layers of the skin. The epidermis is also composed of basal cells, which in turn divide to form squamous cells and melanocytes. Melanoma skin cancer develops from the melanocytes and non-melanomas skin cancer develops from the basal and squamous cells.
Skin cancer is a disease that begins in cells, the building blocks that make up the biggest organ in the human body, which is the skin. Normally in the human body, skin cells grown and divide into many to form new cells taking place the cells that grow old and die. Therefore, skin cancer occurs when the orderly process goes wrong so there is an uncontrolled growth of abnormal meaning that it leads the skin cells to multiply rapidly and grow onto others tissues forming malignant tumors. Even though skin cancer forms in the skin, they are classified based on the types of cells where the cancer starts; Basal cell carcinoma, squamous cell carcinoma, and melanoma.
Skin cancer is the disease in which the epidermis, also known as the outer layer, is infected with malignant cancer cells. The first case of skin cancer was discovered in 1804 by a French physician named Rene Lannec. There are six types. Three major types, and three minor types of skin cancer. The Major forms are basal cell carcinoma, squamous cell carcinoma, and malignant melanoma. The three minor types are sarcoma, merkel cell carcinoma and sebaceous gland carcinoma. The signs and symptoms vary between the different types, but they all have one thing in common, changes in the skin. Changes in the skin could be a growth, a spot that appears to be a rash, or even a sore that doesn’t get any better over time, or turns into a mole. The most common causes of skin cancers is over exposer to UV radiation, tanning or genetics Skin cancer cannot be spread person to person, meaning it is not contagious. Sunburn is the leading cause of skin cancer today. When diagnosing any form of skin cancer, the doctor, or dermatologist may remove a part of the abnormal area of the skin and send it off to a laboratory for testing. Treatment depends on the type of cancer, location stage, cancers aggressiveness or level and the patient’s condition. While most of the time surgery is recommended, it is not always the best method of treatment for everyone. Different surgical procedures that are used to help cure the disease are known as excision, Mohs surgery, curatage and electrodissectaton.
Superficial spreading melanoma spreads slowly on the top layers of the skin before it may begin to penetrate deeper layers of skin. A flat or slightly raised, discolored (tan, brown, black, red, blue or white), and asymmetrical patch of skin. are likely indicators of its presence. In this regard, superficial spreading melanoma may begin with previously benign mole. This type of melanoma is more common in young people, and it accounts for 70 percent of all melanoma diagnosis.
In 2014, approximately 76,000 Americans will be diagnosed with melanoma skin cancer. Melanoma is the most common and most dangerous skin cancer there is. Anyone can get melanoma when not protecting their skin. Throughout this paper there will be discussed the causes, treatments, protection and prevention, and also the effects melanoma has on the human body. Melanoma skin cancer is a cancer that Americans should be more aware of and should take greater precautions when exposing their skin to the sun.
Most parents remembered hearing about the importance of protecting their children from the sun, yet children are still playing in the sun without sunscreen or protective clothing. Many people these days are not taking skin cancer seriously after knowing its significance. Skin cancer has been a growing problem in the United States and millions of people have suffered from it every year. The three most common skin cancers are Melanoma, Basal cell, and Squamous cell, which can cause bumps, sores, growths, etc. Skin cancer is a deadly disease with many causes, but the advantage is that it can be prevented.
