[Gastric metastases of breast cancer]

Breast cancer is the most frequently encountered cancer in women and the first cause of death in the female population. Metastasis may occur ubiquitously depending on the histological type and the presence or absence of oestroprogesterone receptors. We report three cases with gastric metastasis. Signs of gastric involvement are often non-specific and should not be mistaken for simple side reactions to treatment. Hormone chemotherapy is indicated in most situations but surgery may be needed. It should be noted that gastrointestinal metastasis predominates in lobular breast cancers positive for progesterone receptors.
