Melanoma is a serious type of skin cancer. Melanoma actually originates in the melanin (pigment) containing cells known as melanocytes and which are primarily responsible for rendering color to our eyes, hair, and skin. The majority of the moles also contain these cells. Melanoma is the tumor that is malignant and is usually black or brown in color. At times, the melanomas fail to produce the melanin pigment, and during those times their hues transform into purple, red, and pink or assume the color of the skin.
Melanomas have irregular outline. They can be multicolored too. Melanoma may even bleed or just stay put on the skin crust. Melanomas have also been found to develop in pre-existent moles. In the recent years, researchers have found that incidences of melanoma have been on the rise across the globe. On the average, 50,000 melanoma cases are annually reported to the American Cancer Society. But this number does not include those hundreds of cases which go unreported!
The malignant form of melanoma is typical in its appearances. They are generally small in size and appear in either brown-black color. However, malignant melanoma can at times be much larger and also appear in plaques, patches, or nodules.
If the clinical report describes a melanoma as ‘in situ’, then it means that the melanoma(s) has not yet invaded the inner portion of the skin and that it is still in one site or localized on the upper portion of the skin. But if the report refers to the melanoma as invasive, then the melanomas have already moved deep into the skin. What is more, such invasive melanomas are rather dangerous as they can proceed far away from their places of origin or may have broken off to form a separate identity away from the mother tumor elsewhere in the body.
The four types of melanomas are divided as per their location. The first three are in situ in the initial stages but the last one is invasive. The first three ‘in situ’ melanomas are the ‘Superficial spreading melanoma’, Lentigo maligna, and the acral lentiginous melanoma. Whereas the melanoma that is invasive right from the beginning is the nodular melanoma. Mentionably, the invasive form of Lentigo maligna is the Lentigo maligna melanoma.
The most common form of melanomas is the ‘Superficial spreading melanoma’. Prior to moving deep into the skin, this type of melanoma keeps on moving on the surface area of the skin for a pretty long time. Such melanomas may first raise their heads as a discolored portion with uneven boundaries as also in various shapes. They can be just flat or even be a bit raised. The color can be white, blue, red, black, brown or tan. Such melanomas can appear in any part of the body. Nonetheless, they are most commonly seen on the upper portion of the back or trunk (in males) or legs (in females).
Usually the elderly people suffer from Lentigo maligna aftyer being continuously exposed to the sun. This melanoma takes the shape of skin that is damaged especially on the upper trunk portion, arms, ears, and face. The acral lentiginous melanoma looks like discolored brown or black outgrowths especially on the nails (hands and feet) or on the soles.
The invasive nodular melanoma first appears as a black bump. However, it can be of the skin tone, or red, tan, brown, blue, white, and gray. The nodular melanoma is located generally on the scalp arms, legs and trunks of the old guard.
If detected at the initial stages, such cancerous melanomas located on the outer skin can be totally cured. Mentionably, the doctor should be informed if a person suspects the development of melanoma and take the initial precautions to obviate any possibility of the melanoma metastasizing or spreading to other portions of the body when it becomes rather problematic to be treated properly. If melanoma spreads, it may even turn dangerous.
