Is Surgical Removal Of Cysts In Ovaries Needed?

Hello, I have had pain in my lower right abdomen on and off for about a year but when the pain lasted 4 days I went to ER and had an ultrasound which showed approx 7 cm cysts on both ovaries. They have referred me to a gynaecologist but didn't tell me what type of cysts they are. I am 28 and have been on the pill for 4 years so am worried that the cysts might be more serious. I don't know how long I will have to wait to see the gyno so would really appreciate it if you could give me any information. Could you tell me what kind of cyst it is likely to be at this size and is it likely that these cysts will need to be surgically removed? If so, how likely is it that my ovaries will be removed aswell?
