Sorry to see you here on the forum, @"k@th3r1n3" - but you'll find a wealth of information here on every aspect of Breast Cancer, how the system works & anything relating to treatment & side effects.
Usually the 'waiting' is the hardest part to take ...... I believe they have to wait for you to heal sufficiently from your surgeries before they can do either chemo or radiation - I am sure that others who have been thru the same as you will jump on & advise you better than I can (I only had breast conserving surgery, node removal, radiation & now hormone tablets.) I was lucky to avoid the chemo as my tumours were found early & were small & removed with good clearance & no involvement in the nodes.
All the best with your treatment xx
