There 's still a voice in the back of my head that 's unsure if I 'll still need to get surgery , but I ' m trying to silence it . My mom is going to call my doctor and ask if since we 're getting a biopsy , that that means I wo n't have to get surgery . The only reason she 's going to call is because my doctor said she 'd call personally , not that her nurse would call , and also we just want to know for closure .

Question: What is the person worried that they might have ?
