Dermoid potentially cancerous?

Hi there I'm a 27-year-old female and I'm getting laparoscopic surgery next week to remove a 7 cm simple cyst and a 3.6 cm dermoid cyst. I know dermoids are non-cancerous 98% of the time but I wanted to know peoples experience with this surgery and potential cancer concerns. I am aware the simple cyst is of no concern except for potential discomfort. A little background, I had an IUD placed a few years ago. I had follow-up ultrasounds that didn't reveal any dermoid at the time. I then started having pelvic pain and had an ultrasound in 07/2019 which revealed a 1.9 cm dermoid cyst on my left ovary. They decided to monitor this and I will give you the dates on my ultrasounds with the dermoid size

Ultrasound dates/size

-07/2019: 1.9cm. 
-01/2020: 2.5 x 1.4 x 2.4 cm

-04/2020: 2.8 x 2.4 x 2.6 cm

-07/2020: 3.2 x 2.5 x 2.6 cm

-01/2021: 3.6 x 3.5 x 3.6 cm

To my knowledge dermoids are typically very slow growing. Averaging around 1.8mm per year (0.18cm's) and my dermoid has clearly grown much faster than that. Besides the faster growth rate I have constant symptoms like abdominal bloating and fullness and frequent urination. I've never had any blood work to check for ovarian cancer. I'm sure once they remove the dermoid they'll send it off for testing but I'm worried they're ruling out cancer too soon. 

  • Hiya! 
    I've just had my second dermoid cyst removed a month ago. I had an emergency surgery to have one removed back in august just after my 20th birthday. I was so scared but it's a very fast recovery afterwards so try not to worry too much! 
    They send out the cyst for biopsy afterwards and you get a letter saying it's benign if nothings wrong. 
    My first one was 6cm when they cut it out and I was told I only have a small simple cyst on my other ovary so they left it but I've been having problems ever since and ended up in the hospital again at the end of December and was told that actually I have a simple cyst and a dermoid cyst that grew to about 5 cm which ahve both been removed now. 
    Im struggling this time because I've been sent to ahve blood tests and a ct scan done all of a sudden. 
    They'll do a biopsy definitely which will tell you if it's cancerous, I got my letter after a few weeks last time, not this time but my tests were scheduled very fast and I've been sent to do them only 3 weeks after my surgery.

    it seems if they think it could be something more, they're acting quite quick to be honest but if you're really worried ask your gp for blood tests definitely!
