Thanks for your query.Based on the facts that you have posted it appears that you have two cysts in Right ovary detected on ultrasound
One of the cysts is gradually increasing in size over a period of six months,
In majority of cases these cysts are benign in nature however the pathological nature will be confirmed only on histo pathological examination.
Please consult qualified Gynaecologist for clinical evaluation .You may need to undergo puncture and aspiration of cysts by Laproscopic surgery..
The aspirated fluid will help to determine the nature of the cysts and to decide regarding further treatment.
Thanks and Regards.
