Hi, I have read some comments that have scared me and I have questions that I am hopeing can put my mind at ease at least until I see my onc. I am being treated pre op, the tumour is shrinking does this mean that I am unlikely to get secondary cancer? That the treatment is working for me and won't spread? I have read some women have developed secondaries while being treated, how does this happen. As I havn't had my surgery yet I am terrified the cancer will spread even though I am having chemo.
