Is melanoma hereditary?

With the accelerated pace of life today, more and more people are aware of the importance of dermatological health. The number of people suffering from melanoma is increasing, so it is very important to effectively prevent melanoma. And patients are always worried about hereditary issues. So is melanoma hereditary? Let's take a look at the following introduction.

Research has found that for every patient with skin melanoma, there are often multiple such cases, especially when encountering patients with a family history of skin melanoma. So is melanoma hereditary?

Nine percent of the patients, or 385 people, had multiple melanomas. The patients were more likely to have a family history of the disease or to have dysplastic moles. Dysplastic moles can develop into precancerous lesions. The researchers note that dysplastic moles occur in 5 to 10 percent of the general population.

Twenty-one percent of patients with multiple melanomas had a family history of melanoma, compared with only 12 percent of patients with a single melanoma. Thirty-nine percent of patients with multiple melanomas had a history of dysplastic skin moles, compared with only 18 percent of patients with a single melanoma.

About 11% of patients with single melanoma will develop a second melanoma within 5 years of onset. Especially for those patients with single melanoma and a family history of melanoma, the chance of developing a second melanoma is very high, about 20%.
