What infections cause cancer?
Some cancers can be caused by infections with pathogens. Notable among these include liver cancers due to Hepatitic B and C infections; cervical cancer due to infections with Human Papilloma virus (HPV); Epstein Barr virus causing Burkitt ’s lymphoma and gastric or stomach cancer due to Helicobacter pylori infection .
What bacteria causes stomach cancer?
