My doctor said there is a chance it is cancer because of rapid growth

Hi Dr. Parker,

First of all, I want to tell you how informative your website is.  I am 35 my dr found a fibroid in May 2010 and it was 8cmx8cm at that time.  Another ultrasound was done in Sept 2010 and the size didn’t change.  3 weeks ago, I started having leg pain and severe lower back pain so another ultrasound was done.  The size has grew to 8.9cm x 9.9 cm.  My dr said there is a chance it is cancer because of rapid growth.  Is my case considered rapid growth?  Thanks for your time.


Ultrasound is not very accurate to measure the size of fibroids.  The difference in the measurement is 1.9 cm, or 2/3 of an inch, not very much.  The risk of you having cancer is extremely, extremely low.  I wrote an article about this more than 10 years ago and we found that only one of the 371 women with rapid growth had cancer.  You might consider getting a serum LDH, total and iso-enzymes and a dynamic MRI with gadolinium dye as precisely described on this webpage:

I hope this is helpful,
