Hi,
I am sorry to hear of your dx with BC. :-(
The breast surgeon will likely be able to give you information about whether these are two separate issues, or related, in your particular case.
DCIS is a common, very early stage of cancer (by some it even considered "precancer"), while as you mentioned, papillary carcinoma is quite rare. Here is a link to a previous thread regarding papillary carcinoma, which confirms the information you were given about it:

Mastectomy is usually required only if atypical cells, or malignant cells, are widely dispersed in the breast, or if the woman has smaller breasts and the amount of tissue that would have to be removed in a lumpectomy would result in unacceptable cosmetic results. Otherwise, the choice between mastectomy and lumpectomy is usually a matter of pt. preference. Lumpectomy with radiation has been found in many research studies to be as effective (or even more effective, in some cases) than mastectomy in terms of long-term prognosis. Surgery and radiation are local txs, that deal with any atypical or malignant cells in the affected breast.
Chemo is usually required only if the cancer cells are very aggressive (Grade 3), the cancer is large, and, esp., if there is lymph node involvement. Chemo is a systemic tx, that is intended to kill any malignant cells, including "microinvasions" (tiny groups of cells too small to be detected) that may have gotten loose in the body through the blood or lymph systems.
Unless there are certain burning questions that are making you very anxious, rather than call back, I think you'd probably do better to make a list of any questions you have, and take them with you to the consultation with the breast surgeon next week. It is often helpful to take someone and/or a recording device with you, because is difficult to hear and absorb everything in such a stressful situation...
Please keep us posted on how things are going--we care!
Warm regards,
bb
Someone close to me had a core biopsy done by the radiologist, and when the results came back as BC, she was referred to a breast surgeon for removal of her tumor. The surgeon wanted her to have an MRI (along with many other tests, as part of staging) but she was unable to have an MRI d/t her physical disabilities preventing her from getting into the position required for the MRI. She went on to have a lumpectomy, chemo, and radiation, and to date, 3 years out, is doing well. Yay! :-)
I hope that, if you ARE dx with BC, things go as well for you!
