RT Journal Article SR Electronic T1 Cancer of the remaining breast: radiologic contribution to diagnosis JF Canadian Medical Association Journal JO CMAJ FD Canadian Medical Association SP 27 OP 30 VO 114 IS 1 A1 Gutter, Z. YR 1976 UL http://www.cmaj.ca/content/114/1/27.abstract AB Between 1953 and 1973 the mean incidence of a first breast cancer in northern Alberta was 0.47 per 1000 women. However, in women who had had a first breast cancer the crude incidence of a second primary cancer in the opposite breast was 1.3%. The rate of discovery of a second primary cancer increased after a multidisciplinary approach was instituted at the follow-up clinics. Mammography has proved to be valuable in diagnosis. By this technique 19 (36.5%) of the 52 cancers occurring in the remaining breast were identified when they were clinically unsuspected.
