Abstract
Breast cancer is a common cancer worldwide. With the establishment of Thailand's population- based cancer registry and availability of complete data from 2002-2011, it is of interest to investigate the epidemiologic and clinic-pathological profiles of breast cancer based on the population-based registry data. The data of all breast cancer patients in the registry for the period of 2002-2011 were included. All medical records of the patients diagnosed from documents of National Cancer Registry of Thailand were retrieved and the following information abstracted: age, clinical characteristics, and histological variables. Thailand census data for the period of 2002-2011 were used to provide the general population's statistics on age, gender, and other related demographic factors. Over the 10 year-period, 7,711 breast cancer cases were included. The disease incidence under age 40 years was relatively low (4.13/105) while the incidence in the age groups 40 and older was very high (39.2/105). The vast majority of breast cancer cases (88.8%) were diagnosed by histology as primary lesions in the breast. The most common of patients with breast cancer (36.4%) had regional lymph node involvement and the most common of histopathology diagnosed in patients (84.2%) was an infiltrating duct carcinoma. This study showed a high incidence of breast cancer in older subjects, and high rate of breast cancer in Thailand. Future studies should explore clinical and molecular disease patterns.

Summary
There is a wide variability in the incidence rates of breast cancer, with most incidence and mortality cases is still occurring in women in both developing and in developed countries (Ferlay et al, 2010). Westernization is often associated with higher incidence rates of breast cancer. While some developing countries historically have a low rate of breast cancer, the transition to a more Western diet has been associated with increasing rates of this disease (Stoll, 1998). With the establishment of Thailand’s populationbased cancer registry and availability of complete data from 2002-2011, it is of interest to investigate the epidemiologic and clinic-pathological profiles of breast cancer based on the population-based registry data.
