Implants ablation and capsulectomy (Photo)

F40yo wt 20yo breast implants. No records of the surgery, so not sure of implants size, I recall around 300cc, silicon, in front of the muscle. In 2017, a capsule appeared on the left side after taking a hit in a car accident. It got biger (almost one cup size up), harder and painful. I want to remove both capsule and implants, and do lifting. What side effects to expect? Is it possible that taking off the capsule will leave a smaller left than right side? Could it relapse whithout new implants?
