Melanoma is the most dangerous type of skin cancer. Melanoma develops in the melanocytes, which is the cells that produce melanin and give your skin color. The cause of
Melanoma is not exact. Exposure to ultraviolet radiation from the sun and tanning beds increases your risk for developing Melanoma. There are five stages to Melanoma skin cancer.
Stage 0 tumors are noninvasive and have not penetrated below the epidermis. Stage 1 tumors have invaded below the epidermis and into the dermis but are small and have no high risks of spreading. Stage 2 tumors, are larger and have a higher risk of spreading to the nearby lymph nodes or further. Stage 2 melanomas are considered high risk
Many people think that is it possible to achieve a “healthy tan,” but this thought has been proven wrong. Overexpose to UV-A and UV-B rays from the sun lead to premature aging of the skin, as well as the possible formation of skin cancer, know as melanoma. An appearance of a tan is actually a stage of burning and damage to the skin. Although a tan may be desirable to many, the fact remains that more people need to be educated on the dangers of the sun’s harmful rays, and the possible health complications of overexposure.
Melanoma is caused by over exposure to UV which can sometimes cause sunburn, it can be especially critical to those whom are inclined to the disease itself. The tumours derive in the pigment-producing melanocytes which are inside the basal layer of the
Melanoma is the most dangerous type of skin cancer. It develops when unrepaired DNA damage to your skin cells trigger genetic defects that lead you skin cells to multiply at a fast pace and form tumors. Melanoma can often resemble moles and some can come from previous moles. These melanoma moles can range in color from pink, red, brown, purple, white, blue and skin-colored, but more mostly seen as black or brown. It’s said that consumers who use indoor ultraviolent tanning devices are seven-four percent more likely to develop melanoma compared to someone who has never used a tanning bed before. Melanoma is usually caused from intense and over exposure to UV radiation. It has be estimated to kill around 10,000 individuals in the U.S. each year. The lifetime risk of melanoma is 1.5 times higher in males than in females. Melanoma is curable, if it is recognized early and
Tanning salons turn their attention toward cancer prevention and turn their backs on causing skin cancer. Lavine wrote, "The JNCI review noted that indoor tanning can increase a fair-skinned individual's risk of developing melanoma by 55%. And it can take a mere 10 indoor-tanning sessions to cause precancerous DNA damage, reports a recent review study by a Kings College London researcher (Lavine)." Melanoma is not the only form of skin cancer. Tanning beds play a role in the formation of other skin cancers as
Being ambushed by an abrasion on our skin whether it be a pimple, a scar, or something with greater depth such as malignant melanoma can cause quite the adrenaline rush. Diseases of the integumentary system are just as life threating but can be even more mind boggling than a disease occurring internally. For a person to actually see the change in their skin while taking steps to cure it on their own with home remedies and skin care treatments just to find out that the disease is beyond just a simple “break-out” or rash can cause other problems such as stress and insecurity. The integumentary system fights as a barrier to protect the skin and also excrete waste, diseases sometimes hinder this system from doing its main job; which is defending
Those who have light skin, hair, and/or eye colors are at an increased risk for developing melanoma over their opposite counterparts. Risks escalate for those who are sensitive to the sun and develop sunburn easily, have a history of intense sunburns, or never tan. A family history of melanoma is another risk factor associated with developing the disease. Persons with a personal history of melanoma are at a greater risk of recurrence. Significant numbers of freckling and moles in an individual is an additional risk factor in developing melanoma. Controllable risk factors include the use of ultraviolet radiation tanning beds, and the time one spends in the sun under natural ultraviolet radiation (Calianno, 2011). Sunburns in later life and cumulative lifetime exposure to ultraviolet radiation are important factors in the development of melanoma, but blistering sunburns in early childhood markedly increase a person’s risk
Harmful tumors require quick regulation and treatment, as threatening developments may grow quickly and metastasize (spread all through the body) at a disturbing rate. Metastases are auxiliary tumors which can show up at any area all through the body, which is an immediate impact of disease spreading by means of blood and lymph hubs.
the American Cancer Society there are benign tumors, which are rare and often develop in
This disease is present in individuals from all age groups and it is not particular to either gender. Furthermore, malignant melanoma develops after chemical substances have damaged melanocytes by prolonged exposure to sunlight or UV light causing the epidermis to change in color, size and shape. This disease affects several organs and its deteriorating effect disrupts homeostasis and allows other viruses and diseases to weaken the body and cause greater discomfort and pain, which eventually may lead to death. Although the incidence of malignant carcinoma is increasing yearly, it can be diagnosed in its early stages and treated by means of surgical excision. Its ugly and irregular form in addition to redness, inflammation and swelling produced around nevi distinguishes melanoma. If the cancer has progressed to its more advanced stages, radiotherapy or chemotherapy is used to combat the disease. Steps taken to prevent such fatal cancer are simple and for the most part do not require medication. Among these steps avoiding excessive exposure to light, whether natural or artificial, seems to decrease the chances of developing cancer. There are genetic factors, however, that predispose humans to the onset of
Squamous cell carcinoma is the second most common form of skin cancer. Arising from keratinocytes of the stratum spinosum lesions. These lesions often appear, scaly red patches, reddened, or elevated eventually forming a conclave ulcer with elevated edges. If detected early and surgical removal the chances of recovery are high.If neglected and undetected cancer can metastasize spread to the lymph nodes and become deadly (Saladin,
Skin disease is an anomalous development of skin cells, there are three sorts of skin growths: Basal cell is a tumor that develops on various parts of your body that get heaps of sun. It can spread to different parts of your body too. Squamous cell malignancy is the second most basic skin disease. It is normally found in zones of the body harmed by UV beams sun and tanning beds. Melanoma is the most genuine skin malignancy it can get into different organs like your eyes, interior organs like your digestion systems. The sun and tanning beds and any UV radiation exposure increase the risk of skin cancer. Half of all newly diagnosed cancers are skin cancer. (Scarlett W. 371). Solar radiation is an
Melanoma is divided in four different types. Superficial spreading melanoma, Lentingo maligna, Acral lentiginous melanoma and Nodular melanoma. three of them are superficial meaning they occupy only the epidermis and dermis which are the top layers of the skin. The fourth type of melanoma occurs in the deeper layer of the skin and sometimes may invade other areas of the body.
Malignant Melanoma is also called Melanoma or Cutaneous Melanoma. Melanoma is a type of cancer that usually starts with on type of skin cell. The main three skin cells are squamous cells, basal cells and melanocytes. Melanoma starts in the melanocytes. The tumors of melanoma is usually black or brown due to the cells still make melanin. Sometimes it does not make melanin so it will be white, pink, or tan. This cancer can develop on any part of the skin, it is commonly on the chest and back for males and legs for women. The neck and face are other common areas. Having very dark skin can help lessen the risk of getting melanoma in these common areas, but anyone can get it in their nails, bottoms of their feet ,and the palms of their hands. These
The second most common skin cancer is squamous cell carcinoma. Squamous cell carcinoma is an uncontrolled growth of cells in the squamous cell, this is mostly composed of the epidermis. This type of cancer can become deadly if it’s not treated on time. And over 1 million people are diagnosed with squamous cell carcinoma in the U.S per year. Squamous cell carcinoma looks like warts and it is also cause caused by overexposure to the sun's UV rays. Squamous cell carcinoma can also be treated with surgeries or exposure to radiation of X-ray Beams. Finally the most dangerous and deadly form of skin cancer is melanoma. Melanoma is also caused by UV rays and tanning happens when unrepaired DNA is damage in skin cells which leads to the cells to multiply and form deadly tumors and this produces melanocytes in the basal layer of the epidermis. This type of cancer can be treated if it is detected early, but if not it is fatal. An estimated of 10,136 people die by this type of cancer a year in the U.S alone. And melanoma can only be treated by means of surgeries. This is the story of a 23 year old girl named Natalie. Nately began tanning regularly during her freshman year at Boston university. Natalie stated that “I tanned because I felt like it
Among the various risk factors, the strongest include: family history, prior history of melanoma, immunosuppression and the presence of benign or atypical nevi. Furthermore, increased sun and ultraviolet exposure along with sun sensitivity play a strong role in the development of melanoma (source 5 from NEJM). While excess ultraviolet radiation exposure induces the tanning response, by which melanin is transferred to keratinocytes as a protective mechanism, genetic changes in the skin also occur. For example, cutaneous immune function becomes increasingly impaired, an exacerbation in local growth factor production ensues and, most importantly, excess reactive oxygen species generation occurs inducing DNA damage (source 6 or 7 from
