Symptoms of nevus canceration

summary

From a medical point of view, we should pay enough attention to the pigmented nevus growing in the parts that are often subject to friction. Repeated and repeated friction stimulation will make a few normal pigmented nevus turn into malignant melanoma. If malignant melanoma can be found, diagnosed and treated early, the prognosis is usually better. According to the literature, patients with stage I can live more than five years on average. However, if it is found later, the prognosis is often poor. The symptom of nevus canceration? Let's talk about it

Symptoms of nevus canceration

Irregular border, irregular edge or notched, serrated, etc., unlike normal nevus with smooth round or oval contour Asymmetry: half of the nevus looks asymmetric to the other half;

Color variation: normal pigmented nevus is usually monochromatic, while malignant melanoma is mainly black, which can also be brown, brown, brownish black, blue, pink, black or even white;

When the diameter of pigment spot is larger than 5-6 mm or the pigment spot grows up, it should be noted. Usually larger than ordinary moles: pay attention to moles larger than 5mm in diameter. If the diameter of nevus is larger than 1cm, it is better to take a biopsy;

matters needing attention

We should not use physical or chemical stimulants to stimulate nevus for a long time, and we should not use knife cutting, salting and other local stimulation, because long-term and repeated adverse stimulation is one of the important factors for malignant transformation of normal nevus.
