I have fibroids and am worried, are they serious?

than can be but in most cases they just need to be removed to keep from becoming serious ususally they are just uncomfortable and can cause pain during sex for example but only you're doctor can tell you if its the serious kind or not dont worry too much though you're not the only one going through it

No, don't worry.

Over 30% of women have fibroids. The only thing you should do is to go to your doctor and he or she will send you to measure them every 6 months or so. If the size of them didn't change they will leave them there but if they get bigger they take them out to prevent them being cancerous some day.

Good luck!
I am not sure what you mean with fibroid...but as far as is in women health I assume it must be myomes....like a benign tumor on your womb. If it is that...they are not dangerous...I mean they don't become cancer but they can make you bleed during your periods or out of them...if this happens then you would need an hysterectomy ( the only treatment is surgery)
I am a gyn ( not english speaking though so sorry about spell)
Fibroids themselves are not serious. The chance of one becoming cancerous is probably less than 1/500 or even rarer. However, fibroids can lead to irregular or heavy bleeding, and therefore, anemia. They can make the uterus quite large, leading to abdominal pain, or pain with intercourse. Surgery to remove them, or your uterus, can be more difficult if they are allowed to grow. Certainly, an ultrasound every 6 months is a good idea for an objective measurement of your fibroids.
