What are the causes of canthal malignant melanoma?

The occurrence of tumors is related to many factors. Risk factors for melanoma include congenital or developmental abnormalities, melasma, excessive sun exposure, family history, age and race.

The exact cause of canthal melanoma is still unclear, but it has recently been suggested that second-degree sunburn with blister formation plays a greater role in the disease than general sun exposure. Other risk factors include:

①White hair, blue eyes, pale skin, white people are more susceptible.

②Black people or people with dark complexion rarely suffer from this disease. If it occurs, it mainly affects the fair skin on the palms.

③Most scholars believe that nearly half of malignant melanomas occur on the basis of existing moles.

④ Hypoplasia of nevus syndrome, which is an autosomal genetic disease, with large, flat, irregular, thin, and different colored moles all over the body, one or more of which derive malignant melanoma in most patients. Some people have this syndrome but have no genetic tendency and should also be closely observed and alert to the occurrence of malignant melanoma.
