Breast cancer recurrence in the core needle biopsy site: is it a real or a theoretical risk?

Breast needle biopsy is commonly used to confirm breast cancer diagnosis with minimal invasiveness. The risk of cancer recurrence in the site of the core needle biopsy represents up till now a concern. This risk exists theoretically, though it is hard to make clinical evidence. In this article we have studied a 46-year-old woman presented with a skin nodule at the site of biopsy after breast conserving surgery for invasive ductal carcinoma. Histological examination proved local recurrence of primary breast cancer. The possibility of such consequence has to be taken in consideration when performing needle biopsies.
