Breast cancer is the deadliest cancer among women, claiming 660,000 lives annually and affecting one in eight women in their lifetime. Early detection is crucial, with a five-year survival rate of nearly 100% for stage 1 patients compared to only 31% for those diagnosed at stage 4. In the U.S., a woman is diagnosed with breast cancer every two minutes, yet underdiagnosis persists, as fewer than one in three women receive clinical breast exams yearly. Innovative solutions like the K-Pad, which uses menstrual blood as a diagnostic platform, provide a non-invasive, affordable, and accessible way to integrate continuous health monitoring into women's natural rhythms.
