40% of all cancer types are associated with obesity

A new report warns of the role of obesity in cancer. About 40% of all cancers are related to obesity, according to new research, suggesting that these cancers could be avoided if the weight of the individual is kept under control.

Cancer – The report, titled Vital Signs, was conducted by the American Center for Disease Control and Prevention (CDC) in collaboration with the American National Cancer Institute (NCI). C. Brooke Steele, of the CDC’s Prevention and Control Department, was the head of the report.

The findings are particularly important given the alarming statistics on obesity in the United States (and not only). Between 2013 and 2014, the CDC says that 2 out of 3 adults were considered overweight or obese.

How can cancer be linked to obesity

Steele and colleagues looked at cancer rates using data from US cancer statistics in 2014, as well as looking at trends between 2005 and 2014. In particular, the researchers looked at the 13 types of cancer that are traditionally associated with overweight and obesity. These include:

– A type of esophageal cancer (esophageal adenocarcinoma)

– Postmenopausal breast cancer

– Cancer of the colon

– Endometrial cancer

– Gall Bladder Cancer

– Gastric cancer (gastric cancer)

Additionally, the researchers looked at the following cancers:

– Kidney cancer

– Liver cancer

– Thyroid cancer

– Ovarian cancer and

– Pancreatic cancer

The report also looked at the meningioma, which is a slowly growing type of tumor in the brain and multiple myeloma.

Scientists grouped and analyzed data by gender, age, ethnicity, geographical area and type of cancer for each participant. They analyzed the trends both with and without the appearance of colorectal cancer. As they explain, this is due to the fact that the examination for colorectal can reduce the incidence, because the procedure often detects polyps in the r****m before they become malignant.
