Symptoms of melanoma?

summary

Melanoma is a malignant tumor originated from melanocytes in pigmented areas of skin, mucous membrane, eye and central nervous system. So what are the early symptoms of melanoma? Melanoma is a common skin tumor caused by excessive proliferation of abnormal melanocytes, which is highly malignant and accounts for a large part of the death cases of skin tumors. Symptoms of melanoma? Let's talk about it.

Symptoms of melanoma?

(1) Superficial spreading type is the most common type, accounting for about 70%. Most of the patients are about 50 years old. Most of the patients are in the limbs in women, and most of the patients are in the trunk in men. The degree of malignancy is between freckle type and nodular type. In the early stage, they are brown, brown, blue or black. Most of them are rose or peach red. The edge is serrated, and the skin texture disappears. The radiation growth period lasts for 1-12 years, The incidence of lymph node metastasis was less than 5%.

(2) Freckles accounted for 10% ~ 15%, which was the lowest malignant type among the four types. Freckles mainly occurred in the head, neck, back of hands and other exposed parts. Freckles were more common in 60 ~ 70 years old women. The clinical manifestations were larger, flat or slightly higher than the skin brown or Brown lesions. When the radiation growth accompanied by vertical growth, local areas showed focal uplift, the color was still brown yellow, and the lymph node metastasis rate was about 25%.

(3) Nodular type is the most malignant type among the four types, accounting for about 12%. The most common type is around 50 years old. The ratio of male to female is 2 ∶ 1. The most common type is on the back. Clinically, it is a gray and pink nodule. When the lesion continues to grow, its color turns blue black, showing purple black jam like dome or polyp like mass. Vertical growth is the only growth mode. The course of disease progresses rapidly, generally lasting for several months to one year, The prognosis of this type is poor.
