A history of cancer is not necessarily a contra-indication to facial cosmetic surgery. In this situation timing is everything. If you are actively in treatment or shortly after treatment, it is best to wait until your condition has stabilized. A remote history of cancer is less of a concern. Discuss your specific situation with a board certified plastic surgeon. Best wishes
The answer to this question would depend on several factors including type of cancer, the treatment(s) that have been utilized to target the cancer, and whether the patient is currently ill or in remission. It is not unusual in my practice to perform a facelift on a patient who has had breast cancer, but who has been treated and who is in remisiion.
