What does it mean if the nodules or tumors have a hard dark center? My god son is 9 and had a lump on the back right side of his neck He went for a biopsy and they removed four small tumors. Two of them had a hard black core. What could this mean? What are the chances that it could be cancer . If not cancer, what else could it be?
