Using Stress and Strain to Detect Cancer!

Description

This module was written for a first year accelerated or AP physics class. It is intended to provide hands-on activities to teach the concepts of stress, strain and Hooke's law. During the unit, students will apply the concepts learned through the lessons to solve the following engineering challenge: Breast cancer is the second-leading cause of cancer related death among women (Papas, 253) and the American Cancer Society has indicated that mammography is the best early-detection tool available. Despite the fact that mammograms are the most effective early-detector of breast cancer, many women choose not to have them. Of all American women at or over the age of 40, only 54.9% have had a mammogram within the past year (ACS, 15). One reason women attribute to skipping their annual mammogram is pain with 90% reporting experiencing discomfort (Papas, 254). Is there a way to detect the presence of tumors that isn't as painful as mammography but more reliable and quantifiable than a breast-self exam or clinical breast-exams?
