Dr. Larissa Korde provides an overview of breast cancer biology, stages, and types. Breast cancer is the growth of abnormal cells in breast. The stages of development are hyperplasia, atypical hyperplasia, non-invasive cancer or carcinoma in situ, and finally invasive cancer.
Dr. Korde explains the stages of breast cancer, ranging from Stage 0, a non-invasive cancer, to Stage 4, a cancer that has spread to other organs.
Other factors that an oncologist will look at are the receptors that the cancer expresses. Two hormone receptors are estrogen and progesterone, which is treated with hormone therapy. Another receptor is HER2, which treated with HER2 targeted therapy. Triple Negative is a subtype of breast cancer that does not express any of the latter three receptors and is generally treated with chemotherapy. Inflammatory breast cancer is a rare, but aggressive cancer invading the skin tissue
