What is papillary carcinoma?
Many different types of breast cancer start in the cells of your milk ducts. Sometimes, as your ductal cells naturally grow and divide, they make copies of themselves with errors. These bad copies can grow out of control, forming tumors.
Papillary carcinoma is a very rare form of invasive ductal carcinoma. It is called papillary carcinoma because under a microscope, the tumor is strangely shaped and has small bumps or protrusions (called papillae) all around it. Men with breast cancer may be more likely to have papillary carcinoma than women with breast cancer.
Though it is rare, papillary carcinoma responds well to common breast cancer treatments. In fact, women with papillary carcinoma often have a better treatment outlook than women with other types of invasive ductal carcinoma. While some breast cancers get into lymph nodes and spread to other parts of the body, papillary carcinoma is more likely to just remain in your breast and not spread. This makes it easier to treat.
Symptoms of papillary carcinoma
As with other breast cancers, you may notice a lump or change in your breast tissue if you have papillary carcinoma. You may also experience strange discharge from your nipples. If you experience these symptoms, you should talk to your doctor.
