Can I laser remove my mastectomy scars?

It would be best if you provide us with photos so that we can give you a more accurate answer.  You need to understand that all lasers do is lighten up the color of scars, which in most cases if you wait and give it enough time it will lighten up anyways without any help.  Whoever, tells you that lasers help improve scars have them show you the photos of treated side and untreated side one year from laser treatment so you can see the difference if any. 

Unfortunately, any time you cut the skin, the scars left are permanent. Lasers may help with the color but will not remove them.
