Thousands of woman in the U.S. are diagnosed with breast cancer each year. Many of those diagnosed will opt for a surgery called a lumpectomy, during which the cancerous tumor is removed. The problem is that the cancer is not always removed with the tumor. A new tool though, could help women avoid multiple surgeries to remove the cancer. The "Margin Probe" system is able to detect cancerous cells on the edges of removed tumor tissue, helping doctors be sure they get all the cancer on the first trip. The Margin Probe is used together with traditional methods such as ultrasound and visual inspection. The device is expected to become more widely available later this year.
