Dual Primary Malignancies Breast Cancer and Esophageal Cancer: A Case Report

The incidence of concurrent esophageal cancer and breast cancer is relatively uncommon, and there have been a few cases indicating a slight increase in the occurrence of Multiple Primary Carcinomas (MPCS) alongside esophageal cancer. A 36-year-old female patient sought medical attention at the outpatient department due to difficulty in swallowing. A histopathological examination confirmed the presence of squamous cell carcinoma in the esophagus. Surprisingly, within a month of her initial diagnosis, she was incidentally found to have a simultaneous breast tumor. Both tumors responded positively to chemotherapy, and a mid-treatment pet scan indicated complete remission. Studying cases of multiple synchronous primary tumors like this one can provide valuable insights for the development of more effective screening and surveillance protocols, ultimately improving patient care.
