Sorry to hear about your daughter anon, but that is an unusual spot to have a cancer to bind to internally. Ever consider that the attack is coming from the outside in? Maybe she is being chemically targeted as many are. A simple test would be to apply anti fungal foor powder to her back and see if that improves her condition in a few days. Then you will know she is being targeted and it is not an internal source. Many use Ivermectin for internal problems to great affect.
