Nomogram for predicting 5- and 10-year probabilities of (A) OS and (B) BCSS of breast cancer in young women. Draw a vertical straight line from the variable value to the axis labeled “Points” to identify points for each variable. Add up all points, and the total points projected on the bottom scales correspond to the 5- and 10-year survival. Abbreviations: BCS, breast-conserving surgery; ER, estrogen receptor; IDC, infiltrating ductal carcinoma; ILC, infiltrating lobular carcinoma; LN, lymph node.
