Colon cancer screening and prevalence

Colon cancer is among the most killer diseases in the world today and has been established as the major cancerous disease causing the highest mortality in the UK (Wilson, 2010, p. 94). Study indicates that colon cancer screening among adults helps in reducing the likelihood of cancer occurrence among high risk adults (Bandi et al, 2012, p. 5093). Persons of beginning 50 years are considered to be within average risk of contracting colon cancer. Screening for colon cancer is therefore recommended for people who fall within this age to reduce the chances of developing cancer. Older adults from 65 years have increased compliance to this recommendation since they have an increased prevalence to contracting cancer. Research indicates that early diagnosis of colon cancer increases survival rate of cancer victims by approximately 90%. It also increases the identification cancer related cases among patients which consequently reduces the occurrence of cancer related ailments (Lee, 2013, p. 346). Screening of cancer among older adults enables identification of cancerous cells at an early stage when there are still curable.

The significance for cancer screening underlies a basic assumption that colon cancer develops over a range of years. Data collected from observational research indicate that cancer fully develops after 10 to 15 years from ordinary colonic mucosa. In a study, (Pox et al, p. 1462) identified that there need to evaluate whether the current method used in screening for colon cancer is effective and whether it contributes to reduction of colorectal related cancer. According to (McCleary et al, p. 2604), effective colon cancer screening is reliant on allowable rate of complication which is connected to colonoscopy and is needed to get rid of early lesions and adenomas. The author further indicated that there is need for more research to identify how effective screening for CRC is. Randomized trials for colorectal cancer screening among the elderly have not reported any significant falls in the process (Quintero et al, 698, p. 698).

It is evident that there exists a gap in research on the effectiveness of screening for colon cancer among the elderly. My research will hence help me to answer the research question; how effective screening for colon cancer is for older adults. The results will inform on the pre-existing knowledge and skills in prevention and reduction of colon cancer cases…
