Vaginal lump

Hey everyone, I have a large lump inside my Vagina, Dr mentioned it could be a Urethral Diverticulum. I am  worried sick it could be cancerous and it could be up to a year wait for an appointment as my doctor hasn't red flagged or prioritised it. I've been in so much pain, and last week I had a heavy period like bleed. I'm going back to the Dr on Fri as I'm mean't to be Menopausal, my last period was over a year ago! So I'm hoping this will speed things along. My main concern is that the lump is rock hard and covered with a cyst. It runs the whole length of my Vagina Wall and is continuing to grow. I now have pain in my groin area and out towards my rectum. I already had a cancer scare last year (partial thyroidectomy, 3cm benign nodule removed) I also have neuromas in my feet and the Dr is concerned about a lump that has appeared on my tonsil. I know they're unlikely to be connected but I'm feeling very unwell and worried atm! It's always a battle with the doctor to be taken seriously!
