Jennifer Matthews: Jennifer Graham is cutting, pasting and keeping track of her journey through cancer, a journey she thought she would never take. Jennifer Graham: This can't be happening to me. I'm too young for this. Jennifer Matthews: Like most women in their 30s, she never even had a mammogram. Jennifer Graham: I did a self breast exam, and I felt a lump. Jennifer Matthews: Researchers at Duke University Medical Center are working on ways to detect cancer in younger women and find smaller tumors than ever before. Martin Tornai: The idea is that being able to catch the cancer earlier, you'll be able to do something to potentially cure these women earlier. Jennifer Matthews: Radiologist Martin Tornai has created a new type of CT scanner that provides a 3D image of the breast. Traditional mammograms provide only a 2D image and can be painful, compressing the breast and distorting the image. Martin Tornai: Our first priority is to make sure that patients are going to be comfortable because mammography often turns off a group of women from actually going to get regular screenings. Jennifer Matthews: The woman lies on her stomach. A camera swings up and down, encircling the breast and capturing hundreds of pictures. The images are combined to form a complete 3D image. Martin Tornai:Those are very close to her chest wall otherwise deep inside of her breast. Jennifer Matthews: Because of where many tumor is, it may be missed by a mammogram. The new scanner can also detect tumors as small as a tip of a pen. Mammograms detect lesions the size of a marble, making this scanner a more powerful tool to help women like Jennifer live to finish not just one scrapbook, but many, many more.
