Does anyone know if there is a link?

I have always had moles and many, many removed. But they have always been atypical, never melanoma. Since my dx of MS, now I have had a melanoma.

Today my obgyn found that I have a breast lump. Come on! What else is God going to throw at me!?! There is no history of breast cancer or cervical cancer in my family. It might not even be cancer. I am going for a mammo in a couple of weeks.

I guess I am just curious if anyone has read that there is a link. I know that there are some articles out there in regards to a link between MS and melanoma but I wasn't sure if there was one with cancer in general.

I guess I am just trying to sort through all this. I know a lot of you have read up more on MS than I have. Thanks for any input you might have.
