Breast cancer: demographic characteristics and clinico-pathological presentation of patients in Iraq

Breast cancer is the commonest type of malignancy in Iraq. The study was carried out on 721 out of a total of 5044 patients (14.3%) presenting with palpable breast lumps that were diagnosed as cancer. Approximately one third of the breast cancer patients were diagnosed at age 40-49 years; 71.9% came from urban areas; and 75% were married. History of lactation was reported in 63.1% and hormonal therapy in 29%. Positive family history was recorded in 16.2%. Although the lump was detected by the patient herself in 90.6% of cases, only 32% sought medical advice within the first month. Accordingly, 47% of these patients presented in advanced stages (III and IV). The main histological type was invasive ductal carcinoma, in which pathological changes of grade II and III were observed in 56.6% and 39.9% respectively. DNA analysis showed that 80.3% of the carcinomas were aneuploid. The findings of this study justify increasing efforts for establishing comprehensive breast cancer control programmes in Iraq.
