Dr. Harness introduces himself and describes invasive lobular breast cancer.

Dr. Harness, M.D.:
I am Dr. Jay Harness and I am a member of the EmpowHer Medical Advisory Board. I am a general surgeon and breast surgeon by background. I have a major interest in surgical oncology. I am currently a clinical professor of surgery at the University of California, in Irvine, California, and I am past-President of the American Society of Breast Surgeons.

We have to remember that the breast is made up of lobules. Think of a geranium flower and we’ve got the flower part which is the lobules where milk is made during breastfeeding, and then the milk is conducted by the ducts or the stems coming off the flowers, out by the ducts to the nipple. And there are roughly 12 or so major ductile systems in the breast, at the end of which are these lobules.

Interestingly, only about 15, 10 to 15 percent of breast cancer actually arises out in the lobules. We don’t know why. And about 85 percent of breast cancer arises in the ducts. So, invasive lobular breast cancer is actually not a common, not a common diagnosis.
