Hi /k..have a good day..

Last month my waifu has been diagnosed via ultrasound to had a fibroid..i think that one is uterine fibroid (i guess). The diagnose is done at the private clinic.
From the ultrasound result doc were not sure what is exactly fibroid type wether it was intramural, subserosal, submucosal or cervical...but it was sized at 4cm.
The doctor has referred my waifu to the General Hospital but we still not going yet due to several other reason.

Just to gather infos,
1. Is it any k/ experienced this? you may share with me?
2. is it 4cm in size is need for surgery? any non-surgery method can shrink the fibroid?
3. any other bad effects? my waifu still in trying to pregnant stage..
4. any other good advice
