hey there, i tore all of the ligaments in my right foot a few months back, my ankle kept giving out. When I went to the ER they found a tumor on my bone. It is decently large, thick, and round and locatedd on my fibula . My doctor is taking it out on friday. I want to know the truth about these tumors, if there is a chance I could wake up and need to do chemo or something? i am 22 years old, recently quit smoking and I am 5 8. I am 150 lbs. I have experienced pain in the area of the tumor.
