An e-bra and a method of using the said e-bra for early detection of breast cancer are disclosed. The method requires women wear the e-bra once a week for ten minutes. The e-bra uses a high frequency electromagnetic wave or a low power laser to scan the breasts and the bounced echo strength is measured for identifying any size tumor in the breast tissue. When a tumor is detected, the e-bra sounds a warning signal to the woman and she needs to go to a doctor for further examination and evaluation.
