Second Primary Lung Cancer after Breast Cancer: Challenges and Approaches

Abstract

Breast cancer is one of the most common malignancies, with a 10-year survival rate for early non-metastatic stages of over 80%. However, recurrence or relapse may occur decades after completing therapy, and cancer survivors have also a risk of secondary neoplasia especially due to radiation therapy. This case highlights the challenges of an accurate diagnosis and appropriate treatment in patients with second primary cancer and uncommon metastasis.
