scar line nodules.

I have some small nodules appearing at end of scar line and going up the scar. What have any of you done for these? I believe they are all related to skin mets. I believe some of you have had them removed, some had chemo. I tried to bring some info up under search but didn't find anything. Doc tried to tell me might be scar tissue but I knew better. We know our bodies. I just know after the Holiday its back onto chemo. Need info from someone and their experience with these. Just let me get through the Holidays its the worst year I have had. I fear its my last one. Big hugs to you all in the same situation. Sandy
