ELI5: Explain Like I'm 5

CISTI

Okay, so imagine your body is a big house and your organs are all the rooms. Sometimes, things can happen in those rooms that aren't supposed to be there, like a toy getting stuck under the bed. In the same way, sometimes something called a "cyst" can form in your organs.

A cyst is basically a little bubble filled with some kind of liquid or something that shouldn't really be there. It's like a little bump in the room that shouldn't be there.

Sometimes, cysts don't really cause any problems and your body can just ignore them. Other times, they can cause pain or other issues and need to be taken out. Think of it like removing a toy from under the bed that's making it hard to sleep.

Doctors usually use ultrasound or other machines to find cysts and figure out if they need to be removed. So in simple terms, a cyst is just a little bubble that needs to be taken out if it's causing problems.
