(Concern) I have a cyst in my uterus.

During a gynecological checkup, I found three lumps in my uterus. Two of them are not very large, but one is a bit bigger, so we decided to do follow-up examinations. Six months later, the size hadn't increased, so I was advised to continue monitoring. This was three years ago. Since then, I visited the hospital once more, but after that, I haven't gone back due to various excuses and busyness. I really dislike ultrasound exams in gynecology. I'm suddenly worried—can small lumps that haven't changed in size suddenly grow larger? I've heard that as women age, everyone has some lumps in their uterus... I'm curious if people who have found small lumps regularly undergo follow-up exams for years.
