Stats and breast cancer can be uneasy bedfellows. Most of all, no statistics tell you where you personally sit - in the 47% or 0.5% of a chance of some specific thing happening. Recurrence can be affected by age, the particulars of your specific cancer (grade, stage, hormone positive etc), lymph node involvement and all of those factors are to some extent variable. Your oncologist can best advise on your case. There’s also blind luck - some people rated at high risk are fine, others who
might reasonably expect to have no more issues, face a recurrence eight or nine years after their first diagnosis. Treatment is getting better but it’s worth remembering that what happens to one person may not happen to another, no matter what the apparent similarities.
