Breast Cancer - Arm Volume Calculator




Instruction

HOW TO USE:

Using a tape measure, measure the circumferences (in centimeters) at each point (A, B, C, D, E, and F) on both arms (see figure). Then, include these measures in the calculator.

COMMENTS:

The volume of each arm is estimated using the formula for the volume of the frustum of a cone: V = h * (C2 + Cc + c2)/(12 * π), where V is the volume of a segment of the upper extremity, C and c are the circumferences (in cm) at determined segments of the arm, and h is the distance between circumferences (C, c) in each segment (h = 7 cm was used). The arm circumference is measured at multiple segments. Each adjacent pair of measurements is used to estimate the volume of that segment. The volume estimates of all segments of each arm is summed to compute the estimated arm volume (See Figure).
