Anyone diagnosed with Type 2 diabetes is considered to be at risk for developing colorectal cancer. According to scientists at the Massachusetts General Hospital and several other research institutions in the United States and Norway, a family history of Type 2 diabetes also puts individuals at risk for this type of cancer.
In July of 2018, the journal Cancer Prevention Research (Philadelphia) reported on a study of…
- 101,323 women, and
- 48,542 men
without cancer or inflammatory bowel disease (a risk factor for cancer) when first enrolled in the study.
Laboratory tests revealed…
- 1,950 cases of colorectal cancer in the women, and
- 1,173 cases in the men.
Men with a family history of Type 2 diabetes had a 19 percent higher risk of colorectal cancer than men without such a history. Women with a family history of Type 2 diabetes had a 6 percent higher risk of this cancer than women without relatives with diabetes.
Among individuals under 60 years of age…
- men with a family history of Type 2 diabetes had a 65 percent higher risk of colorectal cancer, and
- women with the same history had a 23 percent higher chance of developing this type of cancer.
The investigators suggest further research needs to be carried out to learn whether other researchers can confirm their results.
In March of 2017, the journal Oncotarget published an update on diabetes and colorectal cancer. The news is not good. Deaths from this type of cancer increased by 57 percent worldwide over the past two decades. Although estimates are suspect due to possible reporting errors and different causes of this cancer, people with Type 2 diabetes are at about a 27 percent higher risk than healthy individuals.
The American Cancer Society recommends screening for colorectal cancer begins at age 45. After that time screening should be repeated every ten years for people with an average risk…
- high-risk individuals need to be screened every five years.
- people with Type 2 diabetes and their family members should discuss with their doctor the possibility of testing every five years
In July of 2018, the online journal PLOS ONE reported since having a colonoscopy became widely accepted in screening for colorectal cancer, the incidence of the disease has gone down by 29 percent…
- a colonoscope consists of a lighted tube placed into the rectum to make the colon visible to the doctor.
- polyps or suspicious growths are removed and sent to the pathology laboratory for analysis.
The person undergoing a colonoscopy is sedated and comfortable throughout the procedure.
