Some diseases are more likely to lead to cancer than others. For example, alcoholism can cause cancers in the gastrointestinal (GI) system, and papillomavirus infections can cause genital cancers. Bulimia nervosa (BN) can cause certain types of cancer, too.

Can Bulimia Cause Cancer?

The Link Between Bulimia and Cancer 

So, can bulimia cause cancer? Findings from research on different types of cancers and eating disorders have been mixed. While certain cancers seem to have no correlation with eating disorders, some had an increased risk when an eating disorder was present. (1)

Studies found no connection between eating disorders and breast cancer, female genital cancer, and skin cancer. In fact, several studies found a decreased risk for breast cancer in participants who had eating disorders. (1) But risk was increased for cervical cancer, liver cancer, brain cancer, lung cancer, and throat cancer. 

Although more research is needed to explore the correlation further, there seems to be a connection between cancer and tissues directly affected by eating disorder behaviors. 

What are the Risks for Cancer Caused by Bulimia?

Cancer occurs in tissues that are repeatedly subject to inflammation. In bulimia, stomach acids from repeated vomiting damage esophagus (throat) tissue and cause inflammation. Nutritional deficiencies have also been found to be associated with esophagus cancer. (2)

In addition, people with anorexia are six times more likely to have throat cancer. (4) Scientists believe this connection was due to alcohol consumption and smoking, compounded by nutritional deficiency, not the act of binging. 

In addition, researchers found an increased risk of lung cancer among those with bulimia.

What’s a Rich Text element?

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
