Hi .. I am a mom of four children so I fully understand your valid concerns. I would definitely ask your Dermatologist who removed them, your OB/GYN and you can always ask your Primary Care Doc, too and then get all 3 opinions to move forward with. I don't know if basal cell promotes melanoma more readily or not. I have had some pre cancerous lesions removed on my face via freezing, numerous atypical nevi removed, and one very early melanoma.
The only corelation of anything that was presented to me w/ my history is Pancreatic Cancer and Melanoma Gene Marker .. and my dad died from Pancreatic Cancer. I prefer not to take the marker test even though it is available. My OB/GYN shared that point of reference/interest to me at my last checkup which was so thorough of him, but not something I care to do at this point in my life. Instead, I'll be healthy and proactive.
