Hi

So my sister had all her treatment and it's been almost 5 months and the lump on her neck is still there. They haven't given her a pet scan because they said it was too soon so they said if it's still there in May they will operate to take it out. She was offered a needle biopsy to see if there was still cancer there but then she read on the internet that it's not a good idea because if there is cancer a needle biopsy would make it spread. for those of you that had a lump on your neck, how long after treatment did it go away?
