Melanoma on the back
Melanoma of the back is dangerous because it usually located in the places difficult to access for self-examination.
There are two forms: superficial (70% of cases) and nodular ones. The superficial type is effectively treated and has favorable predictions. A nodular type of melanoma can be a secondary focus of oncology, i.e., metastasis. In this case, the prognosis is poorer.
Melanoma of the vulva and vagina
Usually, melanoma is diagnosed during a routine examination. Pigmented mucosal formations require regular monitoring.
When a tumor grows into the deep layers of the skin, melanoma spreads through the blood and lymph. It affects the brain, liver, lungs, bones.
Melanoma of the liver
Melanoma of the liver is a type of melanoma that occurs as a result of metastasis of the primary tumor. They are the accumulation of melanocytes in the liver. Melanoma of the liver grows rapidly. The liver with melanoma has a tuberous structure and can be enlarged, and its functions are disordered.
Melanoma of the brain
Melanoma of the brain is a secondary malignant tumor consisted of melanocytes. Symptoms of the neoplasm depend on the area of the brain that melanoma affects. The prognosis for melanoma of the brain is poor.
Melanoma of the lungs
Melanoma of the bones
Melanoma affects ribs of pelvic and femoral bones, vertebrae and bones of the head (skull).
Forms of melanoma
There are pigmented and unpigmented melanomas.
Pigmented melanoma is a skin tumor that develops from pigment cells. It has a bright color: red, black, different shades of brown.
Non-pigmented (or achromatic) melanoma is much less common than the pigmentary form of melanoma.
Symptoms of non-pigmented melanoma are redness, itching, swelling. At the last stages of development, white melanoma ulcerates and bleeds.
The main danger of achromatic melanoma is the possibility of metastasizing at an early stage.
Melanoma is a quite rare tumor. It affects not only the skin of the face and body but also the mucous membranes, the structure of the eye. Each of these types has features in the symptomatology and treatment. They are united by the type of cells that form the tumor, and rapid spread throughout the body. Therefore, for any suspicious changes in the skin and mucous membranes, you should consult with a dermatologist. Only the on-time detection of melanoma will help to effectively fight it.
