I also noticed a weird taste in my mouth. Iike sour or metallic.

Tongue Cancer
1/2 tongue removed, replaced by flap from forearm. April 15, 2014
neck disection, 1 lympnode involved, doctors removed all to make sure cancer is gone.
30 rad treatments and 2 cisplatin chemo, doctor said I did not need the third
one. Finished up July 30,2014
Chemo treatment was my choice. The board felt surgery and radiation was plenty to take care of my cancer.
