It's hard to say but it's certainly inspirational! A baby aspirin a day reduces inflammation and blocks COX-2, which supports TNBC growth. I take one daily because several observational studies have demonstrated a reduction in recurrence. Better studies are in progress. Please check out my blog on aspirin for more information.
Please check out my blog on beta-blockers . They could. However, more prospective studies need to be performed. Like aspirin, there are many potential side-effects with beta-blockers. However, I see a great potential for both protecting the heart (following chemotherapy, menopause, other) and, possibly, reducing the chances of cancer recurrence.
