Abstract

There are marked racial and regional differences in the incidence of breast cancer between the three major ethnic groups. For example, Japanese-American women have a very low death rate from breast cancer, only one-fourth that of the American white women. However, the mortality rate of the former group is still higher than that of Japanese women living in Japan. The incidence of breast cancer in American women under the age of 55 has increased approximately 45% in the last forty years. Statistics from the american Cancer Society showed an estimated 66,000 new cases of breast cancer in 1969. It is the number one cancer killer among women, resulting in more than 29,000 deaths in 1969. It is also the foremost cause of death in females between the ages of 40∼44. Despite the gradual but profound increase in this disease, the number of deaths per unit of population has not increased over the years. This is because treatment, largely aided by earlier detection, has been yielding better results. The 5 year survival rate from breast cancer is 82% when localized, but 47% when regional involvement is present. Early diagnosis is therefore essential for futher improvement. Mammography, xerography and thermography are, for the time being, the three possible means, in addition to physical examination, for detecting localized breast cancer.
