High ca125

Hi , been reading thought some post on here and have given some hope . I've been having long and heavy periods since Christmas , I've alway suffered with heavy monthly's but the started to drag on for 10 days or more stop for a day or 2 and than start for another 10 /14 days . End of feb I decided after bleeding  for 3 weeks I should go and see gp, half thinking I was wasting their time and it is all normal for my age (I'm 51 in June ) . But she did an internal and some swabs and said she wanted me to have a internal scan which I did a week later .This showed fibroids and a cyst on my left ovary A week after that I received an appointment for a hystarostmy ( not sure of spelling ,camera into womb ) and a ca125 blood test . They removed a large polyp and said I had a number of fibroids and  a slight thinking of the womb . I have had a phone called today that has put the fear of god in me . My ca 125 levels at 345 which I know is very high , the dr did try and calm me by saying other things could cause rise this number not just cancer but that's all I can think of . I have a CT booked for this Saturday and consultant appoint the week after to tell me what's what , I don't know how I'm going to get though these next few weeks , my poor husband and son are trying to hold it together for me but are very worried . 
 

 Sorry for such long post
