The Utah Regional Cancer Center and University of Utah Hospital have added a new service through which health-care professionals and Utah residents will be able to get cancer information.

All they have to do is call 1-800-4-CANCER.Beginning July 25, calling the toll-free number will connect Utahns to the Cancer Information Service of Utah, a public service of the Utah Regional Cancer Center and U. Hospital in conjunction with the National Cancer Institute.

The service will operate from 8:30 a.m. to 4:30 p.m. Monday through Friday.

The telephone inquiry service provides free information on cancer prevention, detection, types of treatment and resources available to provide support for cancer patients and their families. In addition, names of physicians who specialize in cancer treatment will be provided.

Under the auspices of the National Cancer Institute, the Utah service is one of 23 regional offices associated with cancer research centers throughout the United States. Dr. Harmon J. Eyre, professor of internal medicine at the U. and president of the American Cancer Society, is the principal investigator for the Cancer Information Center.

All of the regional centers and NCI headquarters in Bethesda, Md., are linked by electronic mail to facilitate uniform dissemination of the most up-to-date information on cancer. In addition, the center also has access via computer to the institute's data base for physicians, Physician Data Query, which provides prognostic and treatment information on all cancers and a directory of physicians and organizations nationwide specializing in cancer treatment.

The Cancer Information Service of Utah will be partially staffed by volunteers who will receive 20-30 hours of training leading to certification by NCI. Interested people should call the hospital's volunteer services office, 581-2278.
