What is the probability of inheriting melanoma

Melanoma is a highly malignant tumor, also known as malignant melanoma. Most of them originate from the skin, but can also originate from the eyes, nasal cavity, etc. It can metastasize in the early stage, and the metastatic sites are mostly lungs and brain. Once diagnosed, extensive tumor resection should be performed as soon as possible, and comprehensive measures such as auxiliary immunotherapy should be taken.

Nine percent of the patients, or 385 people, had multiple melanomas. They were more likely to have a family history of the disease or to have dysplastic moles, which can develop into precancerous changes. 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 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 18 percent of patients with a single melanoma.

Family history of melanoma increases risk

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%.

Dermatologists can screen for skin cancer through examinations. In daily life, if we want to protect our skin, we must pay attention to sun protection, apply appropriate sunscreen and wear clothes that can block the sun. For those who are at high risk, genetic testing can help detect their abnormalities.
