Surgery and tattoos

[Kumoku]

Question:

If you have a tattoo over a part of your body and you need surgery where the tattoo is, how will the tattoo look post incision scarring? I know the skin will be slightly raised/bumpy from the scar tissue that will form around where the incision was, but how will the rest of the tattoo look? 

I ask because I'm going to be getting a tattoo over where they put my port in for my cancer. I'm worried if I'll ever need it again and they put it in the same spot they put it in before, how it will affect the overall look of the tattoo.

That'll entirely depend on the skill and care taken by the doctor who is sewing you up!
