Hi everyone, I've come here for some advice. In June 2020 I found a lump in my lower left abdominal area (close ish to the pelvic bone) I had a gynecology appointment and an internal ultra sound and all was normal, I then had an ultrasound all was normal I then had a deep tissue ultra sound again couldn't see anything, every single doctor I've seen can all feel the lump, it started the size of a 50p it's now much larger, closer to a tennis ball size. They marked it out every appointment to show its growth as its grown a lot in just a few months. They've checked for a lypoma and it's not that and since the ultra sounds have shown nothing they think the lump is internal rather than skin/muscle/fatty tissue depth. I'm 23 Yr old female and have a history of cancer in my family, skin, breast, throat and colon cancer. I received an urgent appointment with oncology which is Tuesday 17th November and I'm petrified. The lump causes random pain but the pain can floor me, it's progressively gotten worse as time has gone on since it was first found in June. A couple weeks ago it progressed to making me pass out in pain, I got hot, sweaty, shaking, vomiting unable to move crunched up in pain. This happens with no correlation I've marked every pain episode, everything I've eaten during the day done during the day to see if I can find something causing a trigger and nothing, it can hit me when I'm sat down, stood up, walking, stationary, leaned over bend down laid down ect there's no link. I'm so scared. And I feel like it hasn't been taken seriously as it should have because I'm only 23. It's been 5 months since it was first found for me to get an appointment with oncology but there is supposed to be a 2 week thing for found lumps so I've just been in suspense for 5 months scared every day hoping it doesn't hit me at work, whilst I'm driving, eating, out shopping ect I just feel alone. My family are trying to keep me positive but I just want to feel not so alone in this fear.

Sorry for the long post, any advise would be so welcome.
