Trends in colorectal cancer by subsite, age, and gender over a 15-year period in Adana, Turkey: 1993-2008

Abstract

Although the frequency of colorectal cancer cases was found to be lower in our country when compared to Western countries, a similar right-sided colon cancer shift was observed. The apparent shift of colorectal cancer in young female patients may be related to the advances in diagnostic techniques and may indicate possible diagnostic bias for the female gender. These results also emphasize the importance of collecting regular cancer statistics and of closer follow-up to generate basic epidemiological data and to draw attention to this issue in further detailed analytical research studies.
