borderline serous ovarian cancer

[fibro1]

I was staged 11a borderline serous ovarian cancer in 2009. Had hysterectomy in  november 2008. should I be worried about it going to full blown cancer.

The terms "high grade lesions" and "poorly differentiated" seems completely inconsistent with a borderline tumor.  Aren't borderline tumors very low grade and highly differentiated?

high grade lesions was what the pathology reported. Along with hpv and poorly differentionated.

There is no easy answer. Did you get told if you had any invasive (or microinvasive) implants? This seems to be a factor in predicting a more 'aggressive' type of borderline cancer or one that is perhaps more likely to convert to full blown invasive cancer.
Also perhaps consider second opinion of the pathology. It seems alot of different types of low grade cancers are thrown in the borderline bucket and they have very different behaviour and some are quite hard to identify and may be more likely to reoccur than others and also more likely to become more agressive- you need a good pathologist.
My initial biopsy was borderline however when I had detailed pathology done it was determined to be full blown (grade 2) OvCa. I got this confirmed by 2nd opinion to be sure and comfortable to make treatment decisions.
If you get confirmation that it is borderline or low malignant potential (LMP), be happy and confidnet to get on with life rather than worry about the slim chance of it recurring and becoming full blown cancer. With 2a staging and borderline pathology, you should do great with surgery.
