My mother used to have a wound on her tongue which was caused by a tumor on her brain and she had a surgery 10 years ago and we had it removed, back then befire the surgery the tumor caused her tongue to have a big ulcer or a wound that caused her not be able to speak properly, but the ulcer was not always there, after a week it would be get cured but again after awhile it would be back, this issue got cured by a surgery on the brain but now the ulcer on the tongue is back but very smaller now, do you think it s possible that the tumor has grew again? She used to have a big wound on her tongue nearly for 30 years
