Prognosis for an Infiltrating Ductal Carcinoma

Infiltrating, or invasive, ductal carcinoma is the most common form of breast cancer, according to the American Cancer Society. It accounts for 8 out of 10 invasive breast cancers and prognosis of survival depends on several factors including location, whether it is hormone receptor-positive and stage. Survival rates are calculated at five years after initial therapy and presented as a percentage.


Cancers, like infiltrating ductal carcinoma, which have spread beyond the primary site, have a five-year survival rate of approximately 84 percent, per the New York Times. If the cancer spreads (metastasizes) to other sites, the five-year survival rate drops to 27 percent.

Hormone Receptor

Some breast cancer cells have receptors for estrogen and progesterone–these cells are considered hormone receptor-positive. There is no exact percentage, but women with hormone receptor-positive cells have a better prognosis because those cells grow more slowly and there are more treatment options.

Breast Cancer Stages

There are typically five stages of breast cancer, from 0 to IV. The higher the stage, the lower the chances of survival.

Early Stages

Stages 0 and I both have a five-year survival rate in the 90s. Stage II A has survival rates in the 80s but then, Stage II B drops to the 60s.

Later Stages

Stages IIIA and IIIB both have survival rates in the 40s. Stage IV, the final stage, only has survival rates at 14 percent.
