Surviving a disease such as cancer can leave scars, both physical and emotional. Whether it’s due to a mastectomy or radiation therapy, scars are hard to avoid. Fat-derived stem cells can help patients return close to their original state, providing peace of mind. We also look at the benefits of using oil to balance the amount of fat in a body.
