Is it common or rare for cancer to metastasize to the breast?

Metastasis to the breast is rare. Although cancer can spread to many parts of the body, the breast is an uncommon destination for metastatic cells compared with sites like bone, liver, lungs, or brain. The breast tissue environment is not particularly favorable for distant cancer cells to implant and grow, so only a small fraction of patients with cancers elsewhere develop breast metastases. When they do occur, it typically reflects widespread disease rather than a localized breast tumor. This rarity is why the correct answer is that metastasis to the breast is rare.
