Summary
Laterality was examined in 10,702 cases of breast cancer in Israeli Jewish women. The overall left-right ratio was 1.04 and was higher in women over 60. The only population group with a left-right ratio less than 1 was the group of women born in Asian and Middle Eastern countries outside of Israel. There were no differences between the survival curves of women with right- or left-sided breast cancers at any stage. It is concluded that laterality of tumor is not an indicator of survival in breast cancer.
