Measurement of spiculated malignant lesions on mammogram-do we include the length of the spicules?

Introduction: The size of a malignant breast lump pre-operatively is important to decide between mastectomy and breast conserving surgery. There are no recent studies to determine what is the optimal way to measure spiculated malignant lesions on mammogram which are histologically invasive ductal carcinoma (IDC). This study aimed to determine if the core size or size with spicules has better co-relation with the final histologic size.
