Finished chemo for stage iiia ovarian cancer in oct 2013. Ca125 was 8 6wks ago and 20 now have large right groin node. Is the ca125 jump a lot? Can incisional hernia cause lymph node to swell?

Seek medical exam. Your oncologist needs to know about this groin node if you have not yet told him.Since your ca 125 is still in the normal range, i would not draw any conclusions but your doctor needs to examine you and guide you. It is best not to follow your disease with ca125 right now as it will likely have such fluctuatiosns, causing you to be nervous and anxious, yet it does not help in making treatment decis.
