My mother had stage 1a ovarian cancer just over a year ago and had a full hysterectomy. She gets tested every 3 months. Leading up the this past test her ca-125 have been below 10 which is the benchmark her MD set for her. Her last ca-125 elevated to 14. The woman on the phone told her she wants to see her in 4 weeks for another test. The woman also went onto tell my mother that the lab could have made an error, because this was the 2nd call today she had to make today with similar results ands he said it was pretty rare for that to happen(she may have just said this to make my mom feel better?). She had no chemo done since there was no evidence of cancer cells in surrounding lymph nodes. I know 0-35 is an average number for people. Are they still average for a person who previously had cancer though? Her usual levels are 5-8 and nearly doubled to 14 in 3 months. Honest opinion is sought after! Thanks in advance
