My son recently, found a lump in his supraclavicula fossa. It’s described by the doctors as hard, irregular edges and fixed. He has been seen by ENT and had a biopsy (a core biopsy I believe it’s called) I’m going out of my mind with worry. How long for those who have had experience of yourself or family members being diagnosed with cancer did the biopsy come back? Was it quick? A long time? Do biopsy results with a cancer diagnosis come back quick or do they take time? I’ve never experienced anything like this and I’m so worried. I know from the area the lump is in there’s a high risk of malignancy.
