Breast cancer in Israel. Histopathologic types in the different population groups.

The histological sections of 1,605 cases of breast cancer in Israeli women were examined to determine the frequency of the various histological subtypes inthe different population groups. Infiltrating ductal carcinoma was the most common type in all groups. Circumscribed and medullary carcinoma were relatively less frequent among women born in North Africa than among immigrants from Europe or Asia. Invasive lobular carcinoma was very rare among women born in Asia. The findings are compared with those in other countries and discussed in relation to survival patterns in the different population groups in Israel.
