When you get a colonoscopy, one thing the test looks for is adenomas, a type of polyp that is a benign growth. Not everyone who has adenomas develops cancer but in some cases, adenomas can become cancerous.OLYMPUS DIGITAL CAMERAResearch already shows that eating lots of red and processed meats increases the risk for colon cancer, now a review of the research suggests that they may also increase the risk of adenomas.The study was published this week in Cancer Causes Control. It was funded by the World Cancer Research Fund as part of AICR/WCRF’s Continuous Update Project (CUP), an ongoing review of cancer prevention research.

For the analysis, the authors looked at 26 population studies. Nineteen of the studies were case-control, where participants with and without colorectal adenomas recalled their past diet; the rest of the studies were prospective, where researchers first asked about the participants’ diet then the people were followed over time to see who developed colorectal adenomas.

Evidence is clear that physical activity lowers the risk of getting colorectal Sneakers_dreamstime_14295723cancer. But for those who are diagnosed with this cancer, a new study suggests that survivors who spend more time walking and less time sitting – both before and after diagnosis – may have a longer life.

The study was published in the Journal of Clinical Oncology this week.

Study researchers used data from participants who were part of a large cancer prevention study that started in 1992. Fifteen years later, almost 2,300 of the participants were diagnosed with colorectal cancer. When they entered the study and after the cancer diagnosis, participants filled out questionnaires about how active they were and how much time they spent sitting per week. Continue reading →

Trends in Cancer Research

The links between diet and cancer strengthen yearly, but it can be difficult to conceptualize what are hot research subtopics. One method is to compare raw publication counts per year as they are listed in the PubMed database. To do this, I used Google Spreadsheets to query each of the terms in the table below. The terms were adapted from AICR/World Cancer Research Fund’s document “Summary: Food, Nutrition, Physical Activity, and the Prevention of Cancer: a Global Perspective” (p. 8-9). The resulting counts reflect matches containing the term and “cancer” in titles or abstracts of listings in PubMed.

The cells utilize the same color coding system as AICR/WCRF: the coloring reflects the strongest confidence for an association between the term and a decreased or increased risk for at least one cancer type. Terms with a yellow background were not in the document list and added by me.
