Pigmentless melanoma is an insidious disease of the skin
It is unlikely in modern medicine there is a more insidious and unpredictable disease than cancer. Long-term study of the disease did not give the answer to one of the main questions: why it occurs. The complexity of diagnosis and treatment is compounded by the fact that the symptoms of this disease are very often similar to symptoms of diseases that do not carry a serious danger, and as if his mask. Because the success of treatment depends on what stage it was detected and started on treatment no less dangerous is the asymptomatic development of the disease in the early stages. Among the dangerous and aggressive tumors with a hidden symptoms isolated pigmentless melanoma.
What is melanoma?
Called melanoma a tumor of malignant character, which developed from the epidermal cells that produce the pigment melanin gives the skin its color. The tumor is very aggressive and is characterized by rapid growth. Communication between the cells of this neoplasm is very weak, which leads to a rapid spread of metastases to the brain, lungs, liver, and bone through the liquid environment of the body in a very short time (less than one year since the formation of the tumor).
The danger of pigmented melanoma lies in the fact that it's eight times out of ten, disguised as ordinary moles, which hampers its diagnostics, and thus reduces the chance for early detection.
Types of disease
The highest probability of occurrence of this tumor exists in the open areas of skin that are exposed to sunlight, but may appear on other sites. Depending on the place of education, melanoma is divided into the following types:
- Aktalnye melanoma (subungual and localized on Lagonaki feet).
- Melanoma developing on the mucous membranes.
- Melanoma of the eye.
The symptoms of the disease
Among the major signs of the most common – cutaneous melanoma – are the following:
- The rapid growth of the moles more than 0.7 cm in diameter.
- Change of form existing or newly formed moles on the wrong.
- Fuzzy, often changing the border of a mole.
- Inhomogeneous color of moles – with patches of another color.
- Scaly or gelatinous surface of a mole
- Exudation of moles, including blood, pus, inflammation and itching.
Can occur not all of the symptoms, and only one or two. In addition, the itching, pain, and appearance of various selections on the site of the lesion, may indicate a late stage of the disease.
Along with the pigment, there is also a colorless melanoma. Because the symptoms associated with discoloration of the tumor, are absent in this type of tumors, in most cases, it can be diagnosed only at a late stage, which significantly complicates the treatment.
The reasons for the development of the disease
The most probable reasons of development of this disease are the following:
- Exposure on unprotected skin to direct sunlight.
- The effects of radiation.
- An inherited tendency to develop tumors.
- The bright color of skin and hair.
- A variety of injuries.
Treatment of the disease
The treatment of this disease is directly related to what stage of the disease, the patient went to a specialist. There are four stages of the disease. On the first two stages were emerging on the skin surface of the hearth of the abnormal cells and formation of tumors into the skin. As treatment using excisionof the tumor. On the two stages to separate from tumors and migrate to lymph nodes the tumor cells is rarely possible. Therefore, the treatment efficiency is very high.
In the third stage of the disease the tumor cells almost always have time to get into the lymph nodes, therefore, in addition to excision of lesions, it is necessary to remove the affected lymph nodes, and radiation therapy and chemotherapy.
The effectiveness of the treatment of the disease in the fourth stage is greatly reduced because of the formation of secondary tumor foci of the metastases. In the treatment of, inter alia, required the removal by surgery of a large secondary tumor foci.
Skin protection from direct influence of ultraviolet radiation by a closed clothing and sunscreen greatly reduces the risk of skin cancer.
