What is melanoma's nails?

Melanoma is a serious type of skin cancer and one of the unusual places that may occur is the skin under the nails. The most common in people with dark skin can affect any nail on the leg. Indications that nails on nails affect the nails, include a dark spot or strip on the nail or not saying growth under the nail.

Healthy skin contains melanocyte cells that produce a substance called melanin, which is responsible for changing the tone of the skin of different races of people. It is a pigment, which means that in this case it gives the color of tissue. Solar exposure to human people will start an increase in melanin production, which darkens the skin as a defense against ultraviolet damage by sunlight. When this defensive mechanism is damaged, perhaps through excessive sun exposure, melanocytes that are dark from melanin stores grow from control.

Three different types of cancer can cause leg melanoma. Most of the Commpouze is because of an acroal lentiginous melanoma but may beAlso responsible nodular melanoma or desmoplastic melanoma. Whatever the cancer that occurs in the nails is called subungual melanoma. In principle, it is about the overgrowth of melanocytes in tissues related to the nail.

people with a condition may notice an unusual nail color. Usually, a dark spot appears on the nail that can be brown, black or purple. Cancer may look the same with damage caused by the injury of the nail, so a person does not have to immediately see the meaning of nail color. Dark color often occurs as a stripe that can stretch vertically on the nail.

Honor melanoma does not always include colored nail spots and the condition often appears to be a piece under the nail. Growth of melanocytes can divide the nail or raise it below. In general, cancer does not create pain in the nail area, but cells can bleed or cry.

Since the leg that is most influenced by the nail melanoma is on the big finger, scientists think that physical trauma on the nail can increase the risk of melanoma development. Possible treatment options include surgical removal of cancer, amputation of peak or chemotherapy. Melanoma nails are relatively unusual in light skin people, but is responsible for up to half of the cases of melanoma in African or Asian origin.
