That's the big thing to remember. It's natural to make up scenarios in your head that probably won't happen.
You'll read all sorts about side effects, recovery times, complications etc.

The thing to remember is this: When you read "You might have this" or "You might have that" or "I had this".... it's *possible* outcomes.
Take note of "could" or "might". It doesn't say "will".
When you read may, could or will, it actually means "IF this happens, don't worry... it's normal".

I had that experience with the biopsy. I read all sorts about bruising, swelling, not being able to walk for days.... Nothing. Bleeding stopped with hours & nothing else happened. It's the same with the surgery recovery experience.
Things might happen or might not. Totally different for everyone. We're not robots.
Even the robotic surgery wasn't done by a real robot. What a rip-off. Surely the robot from Lost in Space has nothing to do....

But take any & all experiences from others as "If this happens, it's ok... it happened to me too."
