Stage 2 Luminal A Breast cancer at Oct 2016. Lump left side 15 mm removed. ER 90% positive + 50/90% PR positive. Her2 negative. Low KI67 10%. 17 nodes removed (2 positive + 15 negative). Had classical CMF chimio + 6 weeks radioterapy . Currently with tamoxifene for 3 years and after will be 7 years of aromataze. Just wondering if treatment was enough and what is normally prognostic for this type of tumor. Thanks.
