Authorization taking too long

We have recently joined the scheme, and had to visit the doctor. During the examination it was found that my husband had a nodule to his thyroid, of which we WERE NOT aware of upon joining the scheme. He was then referred to a surgeon who has done tests and it was found that it is highly possibly cancer and it grows rapidly, thus the concern. I understand that there are procedures and policies but I have been going back and forth with this query. I have sent documents, I have even gotten a quote for the procedure, which according to me, is not my job, but I have done everything that is requested from me. The nodule to his thyroid needs to be removed. It is not an ingrown toenail, we need to know the way forward and fast. Everytime you request feedback, you have to wait and then its the same feedback, awaiting doctor's response, awaiting response from non-dec department. When will this investigation be done? When it is too late? We need a response and we need it asap, this has been dragging for too long.
