Incidentally diagnosed invasive ductal carcinoma during routine breast screening: A case report

A 48-year-old female underwent routine mammographic screening, which revealed an irregular, high-density spiculated lesion in the right breast. Further imaging and core biopsy confirmed invasive ductal carcinoma (IDC), Grade 3, ER/PR-positive, HER2-negative, with axillary lymph node metastasis. The patient underwent surgical intervention, and subsequent PET/CT confirmed localized disease without distant metastasis. This case underscores the importance of routine screening in asymptomatic individuals.
