Breast cancer in Israel: incidence and mortality, 1960-75

Between 1960 and 1975, the incidence of breast cancer in Israel rose 20%. A steady rise in incidence was seen for women aged 60 or more years, whereas for women younger than 60 years, the incidence pattern was less regular, showing a definite rise only in the period 1970-75. Mortality from breast cancer also rose among women aged 60 or more years, but much more slowly than incidence. Among women younger than 60 years, breast cancer mortality was essentially unchanged. When mortality rates from a disease rise more slowly than incidence rates, it can be inferred that a greater proportion of new cases are being cured or are experiencing longer survival. It would appear that this is the case with breast cancer in Israel, and this trend, probably the result of earlier diagnosis, is encouraging.
