Breast imaging of Case 2 A: Contrast-enhanced breast MRI (November 23, 2023) demonstrating a large heterogeneous mass in the upper outer quadrant of the right breast (axial view). B: Contrast-enhanced breast MRI (November 23, 2023) showing the same lesion in sagittal view with characteristic malignant features including irregular margins and heterogeneous enhancement. B: Case 2 (Breast Cancer Patient). The timeline illustrates the relationships between HIV diagnosis, initial antiretroviral therapy, breast cancer diagnosis, ABT introduction, surgical intervention (mastectomy), and chemotherapy initiation. The gradual decline in viral load and steady improvement in CD4 + T cell count occurred despite concurrent cancer therapy. Vertical dashed lines indicate key clinical interventions. TLE: tenofovir disoproxil fumarate, lamivudine, and efavirenz; ABT: albuvirtide
