My 13 year was rushed to the hospital in pain and they thought it could be the apendix but when the results returned of the CAT Scan they discovered a mass on her right overy that is 4.5cm and later they did an ultrasound I guess to confirm the findings in the CAT Scan, they also found s cyst 1.2 cm on her right Kidney. The doctor explained to me that it is considered a mass because it is dark and a cyst is clear with liquid. My daughter is so young and I have appointments with 3 different Gyno because the one that saw her at the ER said that the ovary would have to be removed I am afraid for my daughter and want to know if removing the ovary is the only option? Please any feed backs on this will be great.
