I didn't think it could spread to lymph nodes either. My dr assured me not to worry about it. but the report came back risk of micro invasion. Still not sure what it means and couldn't get a real explanation. But when it happens, it appears to be very confusing for everyone! I'm 10 years out. Still vigilant, but fine. And it is sneaky. And yes, my doctor is wonderful. Extremely dedicated, but extremely rare today. I was blessed to have her. Years before BC I had a tumor she was watching. I had been to several drs because of 20 lb weight loss, shaking, anxiety. No one could diagnose me and everyone said I was fine. When I went to her, and she is strictly breast, she examined my whole body. She found a hurtle cell tumor on my thyroid. Rare type. She called for a biopsy right then and there. Wish everyone could have a dr like her! I wish you well on this journey....
