Novel device for microwave cancer detection

Breast cancer is one of the leading causes of cancer deaths among women and early detection leads to earlier treatment and improve survival rates. As the dominating screening technique X-ray mammography has its limitations, microwave imaging becomes the alternative way for breast cancer detection...
