title: Carcinoma of breast associated with pregnancy and lactation.
abstract: Out of 840 cases of breast carcinoma seen over a period of ten years, 18 were found to be associated with pregnancy and lactation. According to the mode of onset and presentation of the disease, these patients were divided into four groups. The average age of these patients was 31.9 years old. Thirteen out of 18 patients presented in a very advanced stage of the disease. In a short period, involvement of liver was noticed in 8, brain in 3, and bones and lung in 2 each. The disease was bilaterally simultaneous in two patients. The acceleration of growth was noticed during second and third trimesters of pregnancy as well as during lactation. The termination of pregnancy in three patients did not alter the clinical course of the disease.
