Hi  

sorry I can't give you any information on what happens next etc but if it gives you any ease to chat to me I'm only a message away,

im in the same situation as you, my mam is also currently waiting to be seen at hospital by the gynaecologist oncologist, thankfully this is at hospital so I'd maybe question the zoom option for your mam? 
 

She is 57 and since I'd say April time she has been suffering on and off with lower tummy ache, no other symptoms at all but due to Covid she was unable to get in for a scan until last week when they found a 9cm cyst or some formation coming from what they could tell her ovary, it has blood flow and is solid or has solid components but they couldn't be sure. She also had a CA125 test done in may which had levels of 16 (normal range) but they are being repeated at her appointment next week. Also like your mam mine to had endometriosis after having me at a young age and has also gone through the menopause around 4 years ago now. 

it is a massively worrying time and I know your mind goes into overdrive and you turn to google for answers so I'm completely understanding of what you and your mam are going through. Please keep me updated and I wish your mam all the best. X
