2 BREAST -- 2 CANCERS ~?~?~? HOW DOES THIS HAPPEN

Pink,

DCIS is precancerous cells, IDC is invasive ductal carcinoma (cancer). They are recommending taking off both your breasts.
Estrogen and progesterone are hormone receptors, and it is good if you are + (positive) for both, so then you can take tamoxifen or an A.I. ( like Arimidex or Femara) to stop the estrogen from producing, as this is fueling your cancer.
Most lymph node reports come after surgery, as they will do either a sentinel lymph node ( SLN) dissection (one - 4 nodes), or an axillary lymph node dissection ( many more, could be up to 30 or so) The lymph node report usually comes a few days - a week or so after surgery, the pathologist has to cut through the nodes to check for cancer cells. It is a better prognosis to be node negative, but do not despair if you have small microscopic cells in the nodes, or more - there are great chemos out there, and other drugs.
Even if you are HER2+ like me - there is Herceptin, a targeted drug therapy that stops the HER2neu+ gene from overexpressing. Wonderful results with this drug.

Hope this helps.
all the best caya.

P.S.
You should look on the main breastcancer.org pages under diagnosis and treatment - you will get alot of great basic information there.
