@cinj, I'd like to add my welcome along with the helpful posts you received from @jacqquie and @bea1972. I agree with Bea that the incision will likely be less tight and flatten with time. It takes a while. Having said that, if you're concerned, don't hesitate to contact your surgeon or send a photo on a patient portal. You don't want to ignore something that might need attention.

@jacqquie, am I to understand that you had colon cancer and now you have a new cancer - squamous cell carcinoma - a skin cancer right at the site of an old incision for surgery or at the exit site of the colostomy?
