If you are diagnosed with lentigo maligna melanoma (LMM), what are the chances of having another, completely separate LMM at another site?  Is LMM genetic?

Our Answer

We have identified the following information that we hope you find helpful. If you still have questions, please contact us.

Can a person develop multiple lentigo maligna melanoma in different parts of the body?

Yes.  Up to 8% of all individuals with some type of melanoma go on to develop a second melanoma.  Lentigo maligna melanoma has been found to be a risk factor for developing a second melanoma, typically in a part of the body that has a history of significant sun exposure.[1]

Is lentigo maligna melanoma genetic?

Lentigo maligna melanoma (LMM) is not believed to be inherited (arising from a genetic predisposition).  LMM is thought to be caused by a history of significant sun exposure.[2]
