Hi,your mother is near menopause
age. As it approaches fibroids will shrink in size with passing years.
thick endometrium &bulky uterus if asymptomic needs regular USG follow up.
Even if symptomatic ,symptoms will decrease with time as menopause(cessation of menstruation
) progress.So wait to take decision for hysterectomy
,she must have endometrium biopsy
to be done before the final decision for surgery .
