Intrinsic subtype characterization of local recurrences and new contralateral primary tumors in patients with low risk breast cancer. Influence of age and primary surgery.

The article discusses a study focusing on local recurrence and contralateral primary tumors in low risk breast cancer patients and its intrinsic subtype characterization. Topics discussed include the impact of age and primary surgery in the recurrence, the exclusion of recurrences to the axilla from the study, and the extraction of RNA from the tumor.
