Melanoma, Malignant Melanoma, Mm

Melanoma, also known as malignant melanoma (Mm), is a form of cancer that develops from melanocytes, the cells responsible for producing the pigment melanin. This tumor usually occurs in the skin, especially in those people who are overexposed to ultraviolet (UV) rays from the sun or sunlamps. However, it can also appear in the eyes or on mucous membranes.

Melanoma can be pigmented, which means it contains melanin, or non-pigmented, which means there is no pigment. Amelanotic melanomas are rare but more aggressive forms of tumors because they often go undetected or are misdiagnosed as other types of skin cancer.

One of the features of melanoma is its tendency to quickly spread throughout the body. It can quickly spread to neighboring tissues and organs through the lymphatic system and blood. Lymph nodes and the liver are often the first sites of melanoma metastasis. In rare cases, melanin or its precursors may be excreted from the body through the kidneys, resulting in the characteristic strong pigmentation of the skin or discoloration of the urine.

The prognosis of the disease greatly depends on the thickness of the tumor and its stage. The thicker the tumor and the more it spreads throughout the body, the worse the prognosis. If the thickness of the affected skin layer does not exceed 0.76 mm, then almost all patients undergoing surgical removal of the tumor at this stage have a chance of survival.

However, in more advanced stages of the disease, when the tumor has spread to the lymph nodes or other organs, the prognosis can be much worse. In such cases, more aggressive treatment such as chemotherapy, immunotherapy and radiation therapy is required.

It is important to note that prevention is the key aspect in preventing the development of melanoma. Regular use of sunscreen, limiting sun exposure during periods of highest solar activity, wearing protective clothing, and regular skin examinations to look for suspicious growths can reduce the risk of developing melanoma.

In conclusion, Melanoma, Malignant Melanoma (Mm), is an aggressive form of skin cancer that can spread and metastasize quickly. Early detection and treatment play a critical role in patient prognosis and survival. Therefore, it is important to consult a doctor if you notice suspicious changes on the skin and follow recommendations for prevention and protection from UV rays to reduce the risk of developing this dangerous disease.

Melanomas are malignant tumors that arise from melanocytes - skin cells that are responsible for the production of the pigment melanin. Melanomas are quite rare in normal cells, but there are frequent cases when they arise from an excess of ultraviolet rays. Typically they form on the skin

Melanoma is a malignant tumor that occurs as a result of the degeneration of melanocytes - cells that have the ability to produce the pigment melanin. Melanomas are most often found on the skin, but they can also occur on mucous membranes and in a person's eyes.
