Bacterial infections can cause cancer, research says

Bacterial infections can cause cancer, according to UNC Charlotte scientists, MedicalXpress reported. 

One of the factors in the development of malignant tumors, according to scientists, is the interaction between bacteria and glycoprotein MUC1, which is secreted by mucous membrane cells. This can lead to the development of a number of oncological diseases, including cancer of the colon, lungs, stomach, liver and pancreas.

About 20% of all malignant neoplasms are linked to any viral or bacterial infection, with the main cause being chronic inflammation.

The protein compounds of mucin, which includes MUC1, protect the inner surface of the digestive tract. Bacteria attach to the specific domain of MUC1, which separates from the molecule and enters the mucous layer, where microbes are removed. The compound can trigger pathogenic signals into the cell, which in turn activate oncogenes.
