Timed-bioresorbable particulates, particularly microspheres or fibers, may be used as a vehicle for delivery of radioisotopes, such as Y-90 and Pd-103 for localized radiotherapy, or as an embolic device. These particulates may also be embedded in polymers, or dispersed in injectable gels or other injectable media for the treatment of various cancers. The benefit of bioresorption, the ability to control the ratio of radioisotopes in the particulate, especially the gamma and beta ratios such as In-111/Y-90 ratio in a particulate, and the benefit of non-conductive implants are disclosed.

In accordance with the apparatus and method of the present invention, a biopotential lesion sensor is placed directly over a lesion in a symptomatic breast and a reference sensor is located away from the symptomatic breast. A plurality of electropotential test measurements are taken during a test period with the lesion sensor and averaged to obtain a primary test potential. This primary test potential can be weighted to compensate for one or more biologic variables such as patient age, time in the patient menstrual cycle, and the time of day during which the measurement is taken. To provide noise enhancement of the primary test potential average measurement, the symptomatic breast is divided into four equal quadrants with one quadrant containing the lesion. One, two or all three of the remaining three non-lesion quadrants is provided with at least one non-lesion test sensor, and during the test period a number of electropotential measurements equal to those taken by the sensor over the lesion are taken and averaged. The processor may then obtain the median value of the averages for the non-lesion quadrants or alternatively the mean value, and it will then subtract this median or mean value from the primary test potential to provide the differential value.
