how to calculate the size of a lesion
The lesion measures at 1.5 cm at its widest point and there was an allowance of 1.0 cm margin on all sides. The pathology report later confirmed that the lesion was benign. To calculate, consider the narrowest margin (1.0 cm) x 2 = 2 cm. Add this figure to the widest measurement of the lesion (1.5 cm) for a 3.5 cm total.
