Other, rare breast cancer types

A small number of breast cancers are uncommon. Each has its own behaviour — and its own treatment path.

Beyond the common types, clinicians meet rare forms such as Paget disease of the nipple, and mucinous, tubular, medullary, papillary and metaplastic cancers. Each is named after the look or behaviour of its cells under the microscope.

What matters with rare types

  • Many grow slowly and have excellent outlooks
  • Treatment always follows the tumour’s receptor profile
  • Rare types can be managed in specialist centres
  • A second opinion brings confidence for unusual cases

Rare does not mean hopeless. With molecular testing and personalised treatment, even uncommon cancers have clear, evidence-based management plans.
