Definition

A type of cancer that usually begins in the glandular (secretory) tissue that lines the prostate and spreads to the ducts within the prostate. IDC-P tends to be large when it is found and tends to grow and spread quickly to other parts of the body. It usually has a poor prognosis (chance of recovery) and is likely to come back after treatment. Also called intraductal carcinoma of the prostate and intraductal prostate carcinoma.
