Breast cancer forms the most common cancer in women worldwide [1,2] and in Arab countries . Breast cancer accounts for about 1/3 of the registered female cancer in Iraq  and with incidence rate of 31.1/ 100 000 in Iraqi women , while it was 18.4 for Iran, 22.4 for Saudi Arabia, 23.0 for Syria, 28.3 for Turkey, 47.0 for Jordan, and 47.7 for Kuwait [5,6]. Recent study in Iraq reported a trend for breast cancer to affect younger age group . This study shows that the highest frequency of breast cancer (32.4%) was in women with age of 21-30 years. Unfortunately, 79.7% of breast cancer cases were in women with age of ≤ 40 years. In addition, 14.9% of breast cancer cases were in women with age of 16-18 years and 52.7% were in those with age of ≤ 30 years. This age shift pattern of breast cancer in Iraqi women was not consistent with previous studies in Iraq [6-12], Arab countries and globally [13,14]. The peak frequency of our study was 21-30 years, while previous studies in Iraq [15-21] indicated that breast cancer frequency peak was in fifth decade of life, in Asian countries in 40-50 years and it was 60-70 years in Western countries . The mean age of women with breast cancer in our recent study was 30.6 ±11.5 years and was not agreed to previous studies in Iraq [6,15-25], Arab countries [13,26] and globally . Thus breast cancer diagnosis age was a decade earlier than previous Iraqi and Arab countries studies and two decade earlier than Western countries .
