Disease Profile

Secretory breast carcinoma

Prevalence estimates on Rare Medical Network websites are calculated based on data available from numerous sources, including US and European government statistics, the NIH, Orphanet, and published epidemiologic studies. Rare disease population data is recognized to be highly variable, and based on a wide variety of source data and methodologies, so the prevalence data on this site should be assumed to be estimated and cannot be considered to be absolutely correct.

Age of onset





Autosomal dominant A pathogenic variant in only one gene copy in each cell is sufficient to cause an autosomal dominant disease.


Autosomal recessive Pathogenic variants in both copies of each gene of the chromosome are needed to cause an autosomal recessive disease and observe the mutant phenotype.


dominant X-linked dominant inheritance, sometimes referred to as X-linked dominance, is a mode of genetic inheritance by which a dominant gene is carried on the X chromosome.


recessive Pathogenic variants in both copies of a gene on the X chromosome cause an X-linked recessive disorder.


Mitochondrial or multigenic Mitochondrial genetic disorders can be caused by changes (mutations) in either the mitochondrial DNA or nuclear DNA that lead to dysfunction of the mitochondria and inadequate production of energy.


Multigenic or multifactor Inheritance involving many factors, of which at least one is genetic but none is of overwhelming importance, as in the causation of a disease by multiple genetic and environmental factors.

Secretory breast carcinoma (SBC) is a very rare, slow-growing type of breast cancer. It was originally referred to as "juvenile breast carcinoma" because it was first recognized in children and adolescents.[1][2] However, many cases reported in the last several decades have occurred in adults of all ages.[1][3] SBC may occur in males or females but like other types of breast cancer, it is much more common in females. Signs and symptoms of SBC most commonly include a painless, firm mass in the breast, which may move when palpated. Some people with SBC also have nipple discharge. There is currently no consensus regarding treatment for SBC, and treatment options may depend on the person's age and the size of the tumor. Options may include surgery to remove the tumor or breast (mastectomy), surgery to also remove nearby lymph nodes, radiotherapy, and chemotherapy. SBC may recur in some cases, but when this happens, it is often in the same area of the breast and after a long period of time (called a late local recurrence). SBC is usually associated with an excellent prognosis (prolonged survival), even when it spreads (metastasizes) to the lymph nodes.[1] The risk for SBC to spread to other parts of the body is thought to be extremely low.[2]


Support and advocacy groups can help you connect with other patients and families, and they can provide valuable services. Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. They can direct you to research, resources, and services. Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. Visit the group’s website or contact them to learn about the services they offer.
