It is an interesting question that you have asked. Of course the logical question would be to treat cancer first and make sure that you’re cancer free before you attempt to have any surgery whatsoever on yourself. At the same time an individual only lives once and even in the face of active cancer, Cosmetic surgery can be performed in order to make an individual feel better about themselves. I would still discuss this issue with your oncologist as well as perhaps your psychiatrist, if you have one, to make sure that the treatment will NOT exacerbate your current medical condition and make you suffer more. I hope this helps and good luck from New York City Plastic Surgery.
