British researchers are developing the prototype for a bra that could help detect early stages of breast cancer. The "smart bra" uses microwave antennae to pick up on temperature changes that "could denote an increase of blood flow to a developing tumor," scientists say. Though microwave technology is not meant to be a substitute for traditional approaches like mammography, MRIs and self-exams, the "smart bra" in tandem with these methods could help detect tumors in their earliest stages. Sure beats a regular old Maidenform. [ABC News]
