What are the early symptoms of melanoma

Melanoma is a common malignant tumor with a high mortality rate. Therefore, early treatment is very important for patients. So how to detect the onset of melanoma early? What are the early symptoms of melanoma?

The early symptoms of melanoma can be summarized as follows: if the tumor is in the peripheral part, it can be easily ignored because there is no visual abnormality. If it occurs in the posterior pole or is in the peripheral part but has spread to the posterior pole, there may be symptoms such as flashes in front of the eyes, deformed vision, smaller vision, central dark spots, and visual field defects. The degree of visual impairment varies depending on the degree of damage to the retina.

Melanoma occurs more often in middle-aged and elderly people, and is more common in men than in women. It is more common in the lower limbs and feet, followed by the trunk, head and neck, and upper limbs. The main symptoms are rapidly growing melanin nodules that may initially cause melanin deposition on normal skin, or increased pigmentation and darker blackness in pigmented moles, followed by the continuous expansion of lesions, increased hardness, and itchy and painful sensations.

Melanoma lesions may be in the form of bulges, plaques, or nodules, or mushroom or cauliflower. When they grow into the subcutaneous tissue, they appear as subcutaneous nodules or lumps, and when they spread to the surrounding areas, they appear as star-shaped black spots or small nodules. A common manifestation is regional lymph node metastasis of melanoma, and even regional lymph node enlargement may lead to medical treatment.

The above introduces the early symptoms of melanoma. I hope that after understanding them, everyone can be alert to the occurrence of the disease, detect it early and treat it early to avoid delaying the disease.
