DCIS or intraductal papilloma CA-125

Hi -

This is my first post. Thank you in advance if you are able to respond!!!

I have had a lumpectomy (benign) in my left breast 5 cm x 7 cm. Now I have developed what appears to be an intraductal papilloma in my right breast. Bleeding from one duct, pain, big lump - surgery scheduled for next week.

I have also had a high (50) CA-125 for two yrs. No doc. has been able to determine cause. I am kinda worried about chance of DCIS vs. papilloma - is there any way to tell the difference? Just a bit anxious…

Thank you!!!
