Ok so iam asking on my girlfreinds behalf, about 4-5 weeks ago i have noticed a lump on her throat, on the lower half of her neck. didnt really pay much attention to it cause it was only about the size of a pea or so, thinking it may go away, but about 3 weeks ago till now the thing juss "inflated" out of no where i mean with in 3-2 weeks this thing GREW! by now it is about the size of golf ball but its not sticking out like you would think. she says she has some what trouble breathing and she is constantly clearing her throat, she has been to the doctors and they have taken blood tests and said that it was not on her thyroid, so they said thatt she needs to get a ultra sound done to know exactly whats up and thats next friday. iam freaking out stressin this issue like crazy. Iam not sure what it could be but naturally i look at from both point of views, it could be cancer or it could be something small...mabey a cyst of some sort, WHAT COULD THIS BE??
