Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern.
As per your complain a white skin tag that is painless and present over the tongue can be a mucosal overgrowth, a growth of
soft tissue fibres known as a
Fibroma or an overgrown taste bud..
The exact nature of the growth will be examined by a
biopsy and as you are already appointed for it, better get it done so that treatment can be planned accordingly..
In case if it is found to be a benign [non-cancerous] growth and as it will be removed once no further treatment is required..
But in case if it is any malignancy further treatment that is
Chemotherapy or Radiotherapy will be decided according to the severity of the nature of lesion..
Hope this information helps..
Thanks and regards.
