The three that I know of are inflammatory, paget's disease, and metaplastic. These are all RARE and aggressive.
Other types of breast cancer can be thought of as a more aggressive version because of their grade. The grading is either 1, 2, or 3. One, being slower growing where 3, grows and spreads faster. The other key to breast cancer is early detection. If breast cancer is detected at a later stage, it is more difficult to --corral the bugger.-- NOT impossible, but more difficult. The patient just has to spend more --quality time-- with her oncologist, surgeon, etc.
The more I learn about breast cancer, the more there is to understand. Science keeps peeling away the layers of the unknown regarding breast cancer. We, as patients benefit from their discoveries.
