Hiah, I had serous pappillary on my ovary and had carbo and taxol - I recently found out I also had clear cell in my uterus but no one else has actually spoken about this to me. When I asked why? - I was told that Serous and clear cell are very similar but I understand that clear cell doesn`t respond well to chemo, unyet my oncologist told me that serous responds really well to the treatment. I question how can they be similar if that is the case? Sorry I can`t be of any help, I am actually really confussed about it now too.
