HI I HAVE BEEN DIAGNOSED WITH A LARGE CYST ON

HI I HAVE BEEN DIAGNOSED WITH A LARGE CYST ON MY RIGHT OVARY, I AM 57, AND I HAVE HAD ULTRASOUND/MRI/ AND CT SCANS, ALL SHOW A GRADUAL REDUCTION IN CYST SIZE, AFTER EACH SCAN OVER THE LAST 3 MONTHS, IS IT POSSIBLY SHRINKING, OR DO THEY ALL SHOW DIFFERENT SIZES NORMALLY? THANKS Marjorie.
