Breast Cancer - Metaplastic: Statistics

Approved by the Cancer.Net Editorial Board, 08/2014

ON THIS PAGE: You will find information about how many people learn they have this type of cancer each year and some general survival information. Remember, survival rates depend on several factors. To see other pages, use the menu on the side of your screen.

Metaplastic carcinoma of the breast is rare, accounting for less than 1% of all breast cancers. Overall, more than 70% of patients with metaplastic breast cancer are diagnosed with stage II or higher (see Stages). The five-year survival rate is the percentage of people who survive at least five years after the cancer is detected, excluding those who die from other diseases. The five-year survival rate of people with metaplastic breast cancer ranges from 49% to 68%.

Cancer survival statistics should be interpreted with caution. These estimates are based on data from thousands of people with this type of cancer in the United States, but the actual risk for a particular individual may differ. It is not possible to tell a person how long he or she will live with metaplastic breast cancer. Because survival statistics for breast cancer are measured in multi-year intervals, they may not represent recent advances made in the treatment or diagnosis of this cancer.
