This answer was rated:

I had a core needle biopsy of a breast cyst taken and this made the cyst drain and collapse, is this because the fluid was too thick to be drained by fine needle aspiration ( which failed to drain the cyst)?

Thanks for this question

No, this is because they punctured the cyst with the biopsy and it drained itself

This is a better type of biopsy on a breast cyst

Thank you but I would like to know why fine needle aspiration failed to drain the cyst

Yes, I'm sorry

I didn't fully understand your question

Your assumption is correct. The fluid was too viscous

What are the reasons for the fluid being too viscous?

This is just the nature of some cysts.

they can have very viscous fluid.

Not necessarily cancer
