, or women who suspect they have breast cancer, the time between detecting a lump and diagnosis can be filled with anguish. Dr. Lawrence Davis, chief of nu- clear medicine at Harper Hos- pital, sympathizes. "I'm not a woman," he says "but I can only imagine what it must be like. Waiting. Wondering. Is it cancer? Am I going to die?" Dr. Davis is directing part of a North American study to evaluate a new breast-cancer detection test. The test is aimed at distinguishing be- tween cancerous and benign abnormalities in the breast. If proven successful, it could cut from days to minutes the time needed to determine if a lump is malignant or be- nign. Harper Hospital is one of about 50 sites in the United States and Canada embark- ing on the project, sponsored by DuPont Radiopharmaceutical, a division of the DuPont-Merck Pharmaceutical Company. I■ I■ The company says a preliminary study, con- ducted independently by a doctor in Cali- fornia, indicated a high success rate. "At present, there is no way of knowing for certain if the breast abnormality is ma- lignant or benign until a biopsy is per- formed," Dr. Davis says. When a woman detects a lump in her breast — either through a self-examination or mammogram — the next step is to get RUTH LITTMANN STAFF WRITER a biopsy, which determines whether or not the lump is cancerous.
