This patient support community is for discussions relating to breast cancer, biopsy, genetics, chemotherapy, hormone therapy, lumps, lumpectomy, lymph node dissection, lymphedema, mammograms, mastectomy, radiation therapy, reconstruction, and self exams.
The grading of the breast cancer tumor is related to the proliferative rate, or how fast the cancer cells are dividing. Grade 1 is low proliferation, Grade 3 means high proliferation, while Grade 2 is somewhere in between.
If your mother already have lung metastases, then chemotherapy or hormonal therapy is the best option. If the lung problem is separate from the cancer, then resection of the primary tumor through mastectomy or lumpectomy could still be curative.
Regards.
