complex cyst & follow-up ultrasound

[weety911]

Hi, I'm hoping that some of you out here might know more about this.  When a complex cyst is being watched, what are they looking for when they do a follow-up ultrasound at 6 weeks?  Is it just to monitor for growth?  Do only cancerous tumors grow while benign ones shrink or stay the same?  I thought complex cysts do not usually resolve on their own.  I even thought I remember reading that they can grow.  So what is the point of having a follow-up ultrasound on complex cysts?  What are they hoping to see?  Maybe I just don't know enough to understand what it's all about--I'm still just learning.

Thanks MarieMichele,
You helped me a lot in understanding a bit more.  My complex cyst is small (just about 3 cm in all directions) but I think the worrisome part is that it has a nodule in it.  Is that what you are referring to when you say the solid ones don't resolve, or do you mean the completely solid ones?  
Would you know if you had endometriosis by the symptoms?  I'm not sure of all of the symptoms, but I know I've never had any fertility problems--we get pregnant at the drop of a hat!  Our first 2 kids were conceived the first month we started trying and our last baby was conceived using condoms!  I thought the fertiltiy thing was a big indication of endometriosis.

They check growth rate or shrinkage and how it is growing, if symmetrical or irregular, mostly solid or mostly fluid.  It is solid ones that cannot resolve.  Once solid, always solid.    And irregular is not good.  Did they give size and descriptions to you?  Some are not complex at all.  They are mis-identified endometriosis instead.
