Surgical scars, even extensive ones, can definitely be treated. The approach might need to be more comprehensive and take longer than treating smaller areas, but improvement is possible. Medical professionals who specialize in scar treatment have experience with post-surgical scarring of all types. They can assess the scar tissue and develop a plan that addresses the specific characteristics of surgical scars. Treatment might be done in sections or stages depending on the size. Many people find that even partial improvement makes a significant difference in how they feel.
