Mucinous carcinoma is an invasive type of cancer that begins in an internal organ that produces mucin, the primary ingredient of mucus. The abnormal cells inside this type of tumor are floating in the mucin, and the mucin becomes a part of the tumor. This rare type of cancer can occur in any part of the body that produces mucin. Approximately 5 percent of all invasive forms of breast cancer have mucinous carcinoma present. Mucinous carcinoma is either pure or mixed.
IDC Type: Mucinous Carcinoma of the Breast
Pathology Outlines - Mucinous / colloid carcinoma
Mucinous carcinoma also known as colloid carcinoma is a particular type of breast cancer characterized by the presence of extracellular mucin and is linked with a more favorable prognosis than invasive breast carcinoma of no special type. Mucinous carcinoma of the breast is an uncommon form of breast tumor, often presenting as a lobulated, moderately well circumscribed mass on mammography, sonography, and MRI imaging. Metastatic disease happens at a lower rate than in other types of invasive carcinoma. We present our 5 year experience with this particular pathology in a retrospective review study. We identified 25 patients with mixed and pure mucinous breast cancer, the tumor size varied greatly from 2 to 19 cm in diameter. A subset of mixed mucinous carcinomas 8 cases showed neuroendocrine differentiation or other associated premalignant lessions. Mucinous carcinoma of the breast is a rare entity with a favorable prognosis due to low incidence of lymph node metastases.

Does anyone else have a diagnosis of mucinous or colloid breast carcinoma? If so, what can you tell me about it? Can't help as you know but am just bumping your thread back up to the top Jolamine is really struggling to get decent information about this cancer - can some of our regular members keep bumping this post please so that it's easily found - just incase someone does join Cancer chat who has knowledge that can help her.
Mucinous carcinoma of the breast — sometimes called colloid carcinoma — is a rare form of invasive ductal carcinoma cancer that begins in the milk duct and spreads beyond it into nearby healthy tissue. Normally, mucus lines most of the inner surface of our bodies, such as our digestive tract, lungs, liver, and other vital organs. Many types of cancer cells — including most breast cancer cells — produce some mucus. In mucinous carcinoma, however, mucin becomes part of the tumor and surrounds the breast cancer cells.
