Can endometriosis grow into serious stage in years coming?  

I am so sorry that you have this horrid illness.

Surgery is usually performed if you want to have children.
The aim of surgery is to remove as much of the endometriosis as possible while still enabling you to have children. You may also need surgery if you have severe pain that isn't responding to painkillers or hormonal medicines, if the endometriosis is larger than 4 to 5cm (1.5 to 2 inches)or if the endometriosis is interfering with the normal workings of organs such as your bowel
This is usually done by keyhole surgery.

It could get worse with age, in some women, endometriosis gets better on its own, but for most, it gets worse without treatment.So I would be sure to accept any treatment offered.

Good luck

hello ! I was diagnosed with endometriosis two years ago. My doctor gave me contrapceptive pills. I am still single and wants to have a baby in the future. I did not undergo any surgery. Last January, I had an ultrasound and my doctor told me that my endometriosis is gone. But, I am still taking oral contraceptives to cure hormonal imbalance. I had my 2 shots of anti-cervical cancer vaccine to prevent cancer. Don't get scared.Positive thinking can also help alleviate your sickness. Go to a trusted ob-gyne. I am sure she'll help you with your sickness. God bless you.

I don't know that it will progress, but I do know that most of the people that I've known that have endometriosis only have surgery because they want to be able to have children. A couple of these people have been able to go on and have successful pregnancies. That said, with the pain and such that you are dealing with and knowing that you don't want to have children, is there a chance that you will be able to find a doctor that will perform a hysterectomy on you so that you won't have to deal with it anymore?
