like help on how to cope with my partner, she lost a breast to cancer o while ago, which never affected our relationship. she now has to have a full histerectomy.( sorry if wrong on spelling) she keeps saying she not a full woman anymore, and i should find someone else. until few months ago we had a good, sexual, long and trusting realationship. she now telling me we should stop seeing each other. i know shes only trying to protect me from the worst of what might happen. how can i tell her that no matter what they cut out off her, she'll still be the one for me. because she thinks its wrong for me to(be with a half woman) her words.

Get her to counseling together with you so you can work it out.

Several issues at play here.

One is her own self-esteem issues sounds like what men feel like when they lose a job... if their identity is their work they feel like they can't contribute, and that's just not so... and just because she's missing some lady parts doesn't men she's not a woman anymore.
After all, she still has a brain and that's what's important and what makes her who she is..

the other probably IS that she's trying to spare you but thing is if you allow her to continue along those lines she'll end up without having anyone at the end and that's really sad for her.
