Skin cancer is caused due to the uncontrolled growth and poor functioning of a cell in the lining of the skin. Change the color and appearance of the skin or development of ulcers (that do not heal) is a clear indication of possible skin cancer.
Melanoma skin cancer: this is the most serious type of skin cancer. Part of the skin cells called melanocytes, which are responsible for the production of melanin (melanin is a substance that gives our skin its color and also protects the cells of the skin from ultraviolet rays). Once they come into direct contact with ultraviolet rays, the cells of the skin (melanocytes) are beginning to produce more melanin, this causes our skin tanning. If we stay in contact with ultraviolet rays for a long time, melanocytes may begin with a malfunction and grow abnormally. This growth can lead to cancer and is called melanoma.
Who is at risk of developing melanoma?
The people who come into contact with excess ultraviolet radiation, the people who have problems with the production of melanin, direct and those that are skinned and have light eyes (has been recorded as melatocytes in skin clara does not produce enough of colorpor melanin pigments and less protection against UV) (harmful rays), people with skin problems and those with hereditary skin problems are at high risk of developing melanoma. Also people who have large number of moles on the skin, people with weakened immune system and those who have Burns blisters in the skin, etc. are at high risk of developing melanoma.
What are the symptoms of melanoma?
Consult your doctor if you witness any of the following symptoms:
1) Spots on the skin of grow them in size and never heal, multicolored nature
(2) Moles keep in growth and start itching and in color or texture (such unusual moles are also known as dysplastic nevi)
(3) Bleeding ulcers grow them and last longer (about a month or more) and will appear again start after getting healed.
(4) In order to develop men, generally, moles, spots and ulcers in the outer skin and face, hands etc. While for women that grow under your Palm or nails & feet.
Types of melanoma:
There are four types of melanoma:
Melanoma superficial spreading (SSM): it is a more common type of melanoma cancer. It takes about a year or more when it is in its first phase called radial stage to spread through the upper skin. During the first phase, it spreads horizontally and less threatening. During the second phase starts grow vertically, making it more dangerous two-stage and difficult to treat.
Nodular Melanoma (NM): this type of melanoma appears very quickly and is considered to be the most lethal/dangerous of the four types. The address of this cancer is upward and inward through the skin and the body, which is more intense and deadly. It usually occurs in the legs, arms, head and neck in light skinned people.
Acral Lentigous Melanoma (ALM): this type of cancer is common in people with dark skin and begins to appear in the nails, palms, etc. This type of melanoma is also aggressive in nature, for the moment that we can diagnose, reaches its advanced stage. This type of cancer starts to grow through the skin and then penetrates the skin.
Lentigo Maligna Melanoma (LMM): people of 65 years of age and above are generally prone to develop LMM is also less common of all four melanomas. This cancer of the nose and cheeks and spread very slowly through the skin. This type of cancer is less deadly and not in the body or other tissues.
How is the melanoma diagnosed?
In most cases it can diagnose melanoma simply examining the infected area (includes self-examination and review carried out by the doctor). This is further accompanied by evidence such as lymph nodes biopsy Sentinel etc. and EPILUMINESCENCE microscopy.
Treatment of melanoma:
Similar to other types of cancers, melanoma: treatment also involves surgery (in which the infected surrounding tissues and tumor deleted), immunotherapy (in which the patient is given chemical stimulating immune (interferon) to help strengthen the immune system and cancer-fighting), chemotherapy, radiation therapy, etc.. Some vaccines are also currently under trial to help destroy cancer tumors and help patients defenses against cancer.
People should be careful of overexposure to ultraviolet light when going for tanning and they have to be alert for any sign of skin cancer.
