Experts explain the early symptoms of melanoma

Melanoma generally occurs in middle-aged and elderly people, and can occur in the lower limbs, feet, trunk, head and neck, and upper limbs of the human body. Knowing the early symptoms of melanoma can help detect melanoma early. So what are the early symptoms of melanoma ? The following is a detailed answer from relevant experts.

(1) Superficial spreading type is the most common, accounting for about 70%. It is common in people around 50 years old, mostly in the limbs of women and in the trunk of men. Its malignancy is between the freckle type and the nodular type. This is one of the early symptoms of melanoma. In the early stage, it appears brown, brown, blue or black, and most of them may appear rose red or pink. Its edges are jagged and the skin texture disappears. The radiation growth period lasts for 1 to 12 years, and less than 5% of people develop lymph node metastasis during this period.

(2) Freckle type accounts for 10% to 15% and is the least malignant of the four types. It is prone to occur in exposed areas such as the head, neck, and back of the hand. It is more common in people aged 60 to 70 years old and more common in women. Clinically, it manifests as a large, flat or slightly higher than the skin surface brown or brown lesion. When radial growth is accompanied by vertical growth, the local focal bulge is still brown, and the lymph node metastasis rate is about 25%.

(3) The nodular type is the most malignant of the four types, accounting for about 12%. It is more common in people around 50 years old, with a male-female ratio of 2:1. It is more common on the back. This is also an early symptom of melanoma. Clinically, it is a gray nodule with a pink tint. As the lesion continues to grow, its color turns blue-black, and it appears as a purple-black jam-like dome or polyp-like mass. Vertical growth is its only growth mode. The course of the disease progresses rapidly, generally lasting for several months to 1 year, and ulcers and lymph node metastasis occur earlier. This type has a poor prognosis.

(4) Acromelanotic melanoma mainly occurs on the palms, soles and subungual areas. During the radiation growth phase, the lesions are brown, brown or black and do not protrude above the skin surface. If irregular brown or brown stripes can be seen under the nail, they extend from the nail bed to the proximal end. The radiation growth phase lasts for about 1 year. If not treated in time, it will enter the vertical growth phase. The lesions will appear nodular and the lymph node metastasis rate will increase accordingly, and the prognosis will also be poor.

The above is an introduction to the early symptoms of melanoma. If you experience the above symptoms, you must go to the hospital for treatment in time. If you want to know more about melanoma, please consult an online expert.
