CA125 over 100

I'd just like some reassurance that cancer normally presents with a higher CA125 than 135. I had a fallopian tube and ovary removed last April due to a dermoid cyst which they were worried was an immature teratoma until the histology came back. My CA125 was only 54 when they were concerned last time. My partner has stage 4 melanoma. I'm worried as we're all our kids have.

I know it could be anything causing inflammation but I'm paranoid.

  • Hello and thank you for your post.

    I can appreciate your concern especially because your partner has stage 4 melanoma, I am sorry to hear this.  This must be a worrying time for you all. However, a high CA125 result does not mean you necessarily have cancer. Remember it is not a perfect test and on its own cannot determine if anyone has cancer. It measures inflammation so there could be other things going on causing it.

    You do not mention it, so I am wondering if you are going to have an ultrasound scan. This is often done alongside a CA125 blood test. It may be able to see what the matter is and hopefully rule out anything serious such as cancer.

    I hope you know more about your situation soon as I know that waiting for tests and investigations to be done and then the results can be particularly worrying.

  • Hi, thank you for your reply. I had an ultrasound today and there's nothing untoward appearing on it so I can relax now? I wonder why the CA125 was high.

  • Hello and thanks for your further post

    I'm glad that your ultrasound was clear. When the CA125 level is raised, this indicates that there is some sort of inflammation in the pelvic area. But it cannot tell the doctor exactly what is causing the inflammation. Other conditions can cause this level to rise such as ovarian cysts, and fibroids.

    I hope this helps.

  • Hi Lyns21,

    did you get answers? My ca125 is raised and I'm so worried xxxx

  • Hi hanx1988,

    I'm waiting on MRI results but the gynaecologist I seen was very reassuring. He said it could be caused by IBS and the scan is precautionary. That they will check my levels again in March and watch for a trend if there's nothing on the scan to be concerned about. CA125 is an unreliable marker as it gives false positives and false negatives particularly in women before menopause so not to be too caught up in it. Easy to say, I know. I've been waiting for 2 weeks for scan results and it's been on my mind a bit.

    Xx

  • Thank you so much. I've frantically been trying to find somebody with high ca125 with more positive answers than the GP receptionist. I sat here and cried for over an hour until I saw your post ️ Hope you're sorted and feeling better very soon xxxx

  • Hi Hanx1988 and thanks for posting.

    I can see than Lyns 21 has replied to you, and she is right when she says that the CA125 blood test can show raised levels caused by other things besides cancer.

    A raised CA125 level indicates that there is some sort of inflammation in the pelvic area. But it doesn't indicate exactly what is causing the inflammation. Other conditions can cause this level to rise such as ovarian cysts, endometriosis and fibroids.

    Hopefully you will know more soon.

  • Hope you find that it's something relatively innocuous x
