A device is provided for aid in early detection of breast cancer. The device comprises a flexible, heat-conductive web, preferably in the form of a disc-shaped patch having an adhesive layer on one side thereof and a peelable layer removably secured thereto by said adhesive layer. On the other side thereof, the device comprises an array of spaced-apart indicators, each of said indicators comprising a dye or a pigment and a temperature sensitive substance (crystalline organic chemical) which melts at a relatively precise temperature which is approximately 0.5.degree. F. different from the adjacent indicator. As many indicators are used as are necesary to cover the desired temperature range. The device is incorporated into the breast-receiving cups of a brassiere and mirror image quadrants of the two breasts are scanned and the device is visually examined to determine the number of indicators which have displayed a change in color, thus apprising the person of the existence of abnormality in the mammary tissue.
A device for use in early detection of breast cancer, which device comprises:
A breast cancer detector having a heat-conductive web divided into a plurality of pie-shaped sectors so disposed and of total area to contact simultaneously opposite side areas of the breast, each sector having an array of temperature indicators of which each indicator senses a specific temperature different from that sensed by adjacent indicators in the array through a predetermined graded temperature range, the ranges of different temperature sensed by the several sectors being substantially identical so that the same specific temperature may be sensed simultaneously at different locations on a single breast for ease in comparing temperatures at mirror image locations on both breasts when a duplicate of the said detector has been applied to the other breast.
