Could post-surgery healing process trigger cancer spread in breast cancer?
ABC News

If a new study in mice ends up holding true for humans, there may be a new explanation for why breast cancer can spread after surgery. The wound-healing process may make the immune system too busy to catch cancer cells that travel around the body. The same study proposed, however, that taking nonsteroidal anti-inflammatory drugs (NSAIDs), however, could help mitigate the possible cancer spread after surgery. Doctors have known for years that after lumpectomy or mastectomy, breast cancer can appear elsewhere in the body after a year or two.
