I work in a breast clinic and assist with biopsies and cyst draining. (delightful hey!? )
Its really not as bad as you're expecting, I promise!
The way it works at our clinic (not sure about other places):
If you do have to have a biopsy, it involves putting a local anaesthetic in, so just like at the dentist, stings a bit, then you shouldn't feel a thing.
After that, the worst part should be the noise the biopsy needle makes! Its quite a loud click but you really shouldn't feel anything.
If you do, tell the dr. Don't keep quiet.
They'll take a couple of samples and then a nurse will press on the tiny little wound (like a papercut!) for a bit to supress the bleeding then put a dressing on it and you're done!
You might be asked to wait for a while just to check you're ok then you can go home.
Take it easy for 24hours, no heavy lifting.
Milk the sympathy!
Not sure how different areas do it but we make you an appointment for the following week to come back in and get your results.
Of it is just a cyst they'll either leave it if you're happy with it or they can stick a needle in and suck out the fluid!
Quick as getting a vaccination just pulling out instead of putting in!
We see a fair few ladies each day, they have a mammogram and then an ultrasound and then the dr will decide if it needs a biopsy or, if its a cyst, they'll talk to you about draining it.
You might not even need a biopsy, but if you do, it really isnt that bad.
Hope that helps?
You might even get me with you, talking rubbish to take your mind off it!
That should make you more worried than the biopsy! lol
