Understanding Metaplastic breast carcinoma

Metaplastic breast carcinoma is a rare type of breast cancer whose tumor cells differ from the cells of typical ductal or lobular breast cancers.

The cells look like skin cells or cells that make bone. Some women have no early signs, while others notice general breast cancer signs such as a new breast lump. It is described in adults.

Signs & symptoms

GARD doesn't list a separate symptom list, but its summary describes these:

  • New breast lump
  • No early symptoms in some women

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.
