Someone in my circle asked me last week about metformin - the cheap diabetes pill the internet keeps saying might fight prostate cancer. He is on active surveillance and wanted to know if he should push his doctor for it.
I get the pull. When you are being watched and waiting on a result, doing nothing feels like doing nothing. A pill feels like action.
So here is what the proper trial - MAST (the Metformin Active Surveillance Trial) in Canada found. 407 men, three years, metformin against a dummy pill. No benefit. The heavier men who took it did a bit worse.
I am not a doctor. But I have watched a lot of hopeful headlines shrink the moment someone finally tests them properly.
Here is the part that helped my friend breathe out: for low-risk cancer, the watching is not "doing nothing". The checks are the treatment. Showing up is the action. He still gets checked every 6 months, just to be sure.
Have you ever chased a supplement or a pill you read about online? What made you try it, or what made you stop? I would like to hear it.
