Welcome to Healthcaremagic Forum!
I am anticipating that Your mother has had an ultrasound
or ct scan
done.The treatment depends on the size of the cyst and the symptoms that it is causing.It is most important to rule out that the cyst is a non malignant one.You have not mentioned whether Your mother has attained menopause
or whether there is family history of such cysts.
Treatment usualy depends on the size of the cyst and the symptoms.
for small asymptomatic cysts wait and watch attitude along with regular follow up is required.Painkillers and hormonal
therapy may be considered.
Cysts that occur in postmenapausal women require more thorough investigations like laproscopy,surgical biopsy
or estimation of tumour markers like CA-125
If cysts are large and persisting surgery is indicated and it is upto the operating doctor to decide this.Ovaries may be removed or conserved based on the doctors decision again.
Hope I have answered your query
Bye for now!
