Bilateral breast cancer frequently emerges as a second primary cancer. Lymphoma and mucinous carcinoma of breast are very rare. Here we present a case, of bilateral breast cancer with metachronous lymphoma and mucinous carcinoma. Case History: 57-year old female had received chemotherapy and radiotherapy for stage IA Diffuse Large B Cell Lymphoma (DLBCL) located in right breast. At 14th month of her breast DLBCL diagnosis, a diagnosis of mucinous carcinoma was determined in her left breast. After surgery, adjuvant anastrozole was initiated. The patient is still in follow-up with remission at her sixth year of DLBCL diagnosis and fifth year of mucinous carcinoma diagnosis. Conclusions: The evaluation of unilateral breast cancer patients in terms of bilateral breast cancer occurrence risk has become important.eninfo:eu-repo/semantics/openAccessBreast CancerChemotherapyLymphomaArticle183846848WOS:0008917714000483590057310.4103/jcrt.JCRT_1008_20Q4
