Hi Swati, your apprehensions about not getting good treatment is misplaced. I am not sure which hospital your mom is getting treatment, I hope it is a cancer speciality hospital. In India, onco surgeons do have expertise in reconstruction of total or near glossectomy with techniques like dynamic flaps etc.

Needle biospy is not as reliable as wedge biopsy and it is a good idea to have a second opinion. You would need to push other onco in his team to have that biospy done as quickly as possible as any incisional biospy result will take a week (approx). Take his onco's number and give him a call where ever he is.
