Based on the nature of the cancer, and the treatment, and perhaps as an alternative to surgery, one can consider prosthesis. Prosthesis, essentially allow one to replace/enhance parts of body
    lost to injury, deformity or other reasons.
     
    If you lost a limb to cancer, there are prosthesis for legs/arms etc. There is a lot of international research and enhancements in this segment with a view of giving the best possible outcome and
    help aid in leading an independent life. The prothesis have evolved significantly over time and continue to evolve.
