Hi, mom was diagnosed with stage 3c/4 ovarian cancer. Had 3 lots of chemo's then surgery and now 3 cycles of chemo again. At the time of diagnoses CA 125 was 1400. After surgery, just before starting chemo again the levels were 85 and after completing 4th cycle they are 97.5. Is this normal? How long did it take for your levels to return within the normal range?
