Rare Forms of Breast Cancer
Only a very small percentage of people who are diagnosed with breast cancer have a rare type. Having a rare type does not mean that survival is worse. In fact, many have a better general prognosis than more common types. The outcome of breast cancer depends on many factors including tumor size, whether the cancer has spread to the lymph nodes under the arm, how poorly differentiated (or “wild looking”) the cells are compared with normal cells under the microscope, and how many and how fast the cancer cells are dividing. A breast cancer diagnosis is unique to each person. While there are general categories, it's important to speak with your health care team to determine your special circumstances.
