I'm 36 diagnosed with bone lesion of forehead. it's been painless & slow growing for a year. i am really worried. i have some nerve pain around the sinuses and lump sometimes. i've read about sarcomas, could it be one? could it be anything else?

Bone lesion: I would think that your diagnosis of a bone lesion in your four head has been ruled as simple and that the possibility of sarcoma has been ruled out I would ask my physician exactly what kind of lesion I have and that would put your mind at rest

A year: A year is to long to keep saying, "Maybe it will go away." No matter the cause, and there are many possibilities, you must see a Physician do be diagnosed and treatment planned. Waiting will only allow problem to worsen.
