Hello Dear,
There is a possibility that the MRI is showing no improvement because it takes some time for the wound to heal completely. It is good that you are not having pain and are able to walk properly. Also it is a good sign that you are gaining weight. A repeat biopsy will give a definitive picture of the recovery but is usually not necessary. Your doctor will guide you better in this.
