abstract: background: evidence suggests that the incidence of many cancers including bowel cancer vary according to socioeconomic status and education. in case of colorectal cancer, the direction of this association might be even different for anatomical subsites. the aim of this study was to describe the variation in the incidence of colorectal cancer by subsites across north of england and co...

Background: Breast cancer is one of the most common diseases in women and causes more deaths rather than other cancers. The increasing trend of breast cancer in Iran makes clear the need of extensive breast cancer research in this area. Some studies showed that in the variety countries and even in the different areas in one country has different risk of breast cancer incidence and this is a rea...

background : the incidence of thyroid cancer has varied from 2 per 100,000 in europe to 21 per 100,000 in the hawaiian chinese population and is 2-3 fold more common in females. middle east cancer consortium figures from 1996-2001 have recorded different age standardized incidence rates that ranged from 2 per 100,000 in egypt to 7.5 per 100,000 among israeli jews. in jordan the age standardized...

background: lung cancer is one of the most fatal and preventable cancers. in this study, we sought to investigate about trend in incidence of lung cancer in kermanshah province -iran. methods: all pathology reports on lung cancer were collected from pathology centers in kermanshah province in recent 11 years (1997-2007). after merging the data with cases reported in, province health centre data...

Background: Colorectal cancer is the fourth most common cancer, in terms of incidence throughout the world. There are some differences for risk factors involved in the incidence of tumor in different anatomical subsites of large bowel. However, most investigations have not studied the association between dietary factors and colorectal cancer subsites. Thus the current ecological study inves...

Introduction: Environmental and occupational human exposure from neutron source can lead to the serious biologic effects. The aim of this study is to evaluate the cancer incidence risk for various human organs at different neutron dose levels due to exposure from an Americium-241/Beryllium (Am-241/Be), a standard neutron source for calibration purposes. Material and Methods: We measured ambient...
