You have not described the exact size of the cyst in your question, nor have you given information about your age, all this information is necessary. In general, in such problems, you may have to face some problems related to menstruation or discontinuity, but as you told that you are not facing any kind of problem but it has been revealed in your normal check sub, then you should take care of it. Don't be careless.
If you want, you can consult another doctor at once, sometimes the information can be wrong, otherwise, you start treatment. Don't waste too much time on this because this time can go ahead and take a formidable form. Sometimes a cyst is formed in some cases and also dissolves on its own but it depends on case to case.
If you do not want to resort to any kind of surgery, then you can also take the shame of homeopathy or Ayurveda. There are treatment methods in both Ayurveda and Homeopathy which help in dissolving the cysts, this treatment may be relatively long but as you mentioned you are not facing any problems then you can also opt for this option.
As far as laparoscopy is concerned, it is a minor surgery in which a small incision is made and operated on, followed by two or three stitches. It takes about 15 to 20 days to recover completely, during which you may have to abstain from eating and drinking.
Thus, this whole treatment process is dependent on the size of the cyst in your case and your age and other condition, so decide on that basis.
