Evaluation of EM absorption loss over breast mass for breast cancer diagnosis

摘要

This paper presents electromagnetic (EM) absorption loss over breast mass as a new approach in the detection of breast cancer tumors. A linear curve of absorption loss over breast mass is used to establish acceptable normal absorption loss values. Since tumor-infected breast tissues should have higher absorption loss than normal breast tissues, the measured absorption loss of a tumor-infected breast will be higher than the established normal absorption loss value, and the breast will be diagnosed as infected. EM simulations of normal and infected breast tissues are run at 915, 2450, and 4000 MHz. Results show that 915 MHz presents the best linear curve fit and resolution. Also, the absorption loss for an infected breast, at 915 MHz, is higher than the absorption loss for a normal breast and is least affected by tumor location.
