Endometrial cancer is very rare in someone before menopause. A biopsy would have to be done to see if there are any atypical cells, but given your age it is unlikely.
I am an ultrasound tech and have seen too many woman in your age group with endometrial hyperplasia. The most common causes are:
1. hormones - requires hormone treatment (ie think progestrone but I could be wrong on that)
2. polyp - very common even in young patients. Diagnosis can be made with special ultrasound called a hysterosonogram. It can be painful, but you are awake and unmedicated for it. It might be a good place to start for you.
I don't think that a D&C is the first choice in treatment. Infact, if the cause is hormonal having the D&C would not have any benefit/cure since a D&C simply scrapes the innermost layer clean and hyperplasia is a thickening of all layers of the endo (the D&C would help if there was a polyp, but they usually need to know the polyps location to be sure they do a thorough job and get it out). Also, there are risks with having a D&C which include developing adhesions in the endometrial canal which can make getting pregnant difficult or impossible in the future (if that is something you would want).
I think you need more information. I think maybe hormone tests would be beneficial too to see if something is simply off there. If the hormone tests are normal I would have the hysterosonogram. If that is normal than maybe a D&C could be considered though I really don't think it will change anything.
