It’s always best to speak with the doctor or surgeon about the reasons why treatment should be done. There are usually many details involved in making a decision for treating scoliosis.
In general, treating scoliosis is done to protect the lungs and heart (giving them room to grow properly) and comfort, to relieve (or prevent) pain. People with scoliosis tend have more back pain and as they get older, the curves can worsen. Treating scoliosis in adulthood is more difficult than treating in adolescence.
