Several studies report varying incidence rates of cancer in subsites of the colorectum, as an increasing proportion appears to develop in the proximal colon. Varying incidence trends together with biological differences between the colorectal segments raise questions of whether lifestyle factors impact on the risk of cancer differently at colorectal subsites. We provide an updated overview of the risk of cancer at different colorectal subsites (proximal colon, distal colon, and rectum… 

Physical activity and mortality in patients with colorectal cancer: a meta-analysis of prospective cohort studies.

A systematic review and meta-analysis provides comprehensive evidence that PA performed before or after cancer diagnosis is related to reduced mortality risk among CRC survivors.

Physical Activity and Colorectal Cancer Risk by Sex, Race/Ethnicity, and Subsite: The Multiethnic Cohort Study

The findings confirm the inverse association between physical activity and colorectal cancer, which appears to be stronger in men, and suggest possible differences in the strength of the association by race/ethnicity and anatomic subsite of tumors.

Association of physical activity and sitting time with incident colorectal cancer in postmenopausal women

An inverse association between leisure time PA and the risk of CRC, particularly for rectal cancer is observed, and there was no association between ST and CRC in multivariable models.

In most observational studies, greater physical activity is associated with a lower incidence of colon cancer, while in the interventional studies, results were more diverse.

Height and body fatness and colorectal cancer risk: an update of the WCRF–AICR systematic review of published prospective studies

The positive association between height and risk of CRC suggests that life factors during childhood and early adulthood might play a role in CRC aetiology.

Physical activity, obesity and sedentary behaviour and the risks of colon and rectal cancers in the 45 and up study

Evidence suggests that a healthy weight and vigorous activity are essential to reduce CC risk since these factors may be independent of each other.

Association of sedentary work with colon and rectal cancer: systematic review and meta-analysis

Evidence is found of association between sedentary work and the risk of colon or rectal cancer, independent of sex, control of body mass index and assessment of sedentary behaviour, which could be an important means of preventing colon andrectal cancer.

Physical Activity and Gastric Cancer Risk: A Systematic Review and Meta-Analysis

This meta-analysis suggests a protective effect of physical activity regarding gastric cancer risk, especially in Asian populations.

Cancer and Physical Activity

Physical activity is also associated with a decreased risk of colon adenomas (polyps), a type of colon polyp that may develop into colon cancer, however, it is less clear whether physical activity is associated with lower risks that polyps that have been removed will come back.

It is found that physical activity reduced colon cancer risk, specifically for right-sided tumors and for lean participants, but not rectal cancer.

It is suggested that physical activity may prevent colorectal cancer among Japanese men, and this inverse association was essentially limited to colon cancer.

Recreational Physical Activity and Cancer Risk in Subsites of the Colon (the Nord-Trøndelag Health Study)

The inverse association of recreational physical activity with cancer risk and mortality in the transverse and sigmoid segments of the colon may point at increased colon motility and reduced fecal transit time as possible underlying mechanisms.

Body size and composition and risk of rectal cancer (Australia)

Waist circumference and fat mass may be weakly related to risk of rectal cancer and there was no evidence that risk differed by sex for any of the anthropometric measures.

Comparison of risk factors for colon and rectal cancer

The findings support previous suggestions that family history and physical activity are not strong contributors to the etiology of rectal cancer and should take into consideration risk factor differences by subsite.

It is suggested that higher BMI was associated with an elevated risk of colorectal cancer, and the positive relationship was not altered by estrogen exposure among postmenopausal women.

Body size and risk of colon and rectal cancer in the European Prospective Investigation Into Cancer and Nutrition (EPIC).

Waist circumference and WHR, indicators of abdominal obesity, were strongly associated with colon cancer risk in men and women in this population and may vary depending on HRT use in postmenopausal women; however, these findings require confirmation in future studies.

Relation of body mass index to cancer risk in 362,552 Swedish men

Obesity and weight gain increase the risk for several forms of cancer in men, and underscore the need for further study into carcinogenic mechanisms and preventive interventions.

Obesity and colorectal cancer risk in women

It is suggested that obesity is associated with a twofold increased risk of colorectal cancer in premenopausal women but is not associated with altered risk in post menopausal women.
