Marking of the breast cancer lesion using the subcutaneous mammary veins as the benchmark. a The positional relationship between the breast cancer lesion (green) in the contrast-enhance computed tomography maximum intensity projection image and the construction of the superficial mammary veins (yellow dotted line) is shown. b Using AccuVein^®, the subcutaneous mammary veins were marked on the skin, and the positional relationship between the vascular construction and the breast cancer lesion in the contrast-enhanced computed tomography maximum intensity projection image was collated. This allowed us to visualize the breast cancer lesion in the contrast-enhanced computed tomography maximum intensity projection image on the skin. c In the removed specimen, the breast cancer lesion (red line) expanded as much as the lesion shown in a, b; DCIS ductal carcinoma in situ
