Liver Cancer in Vietnam?

I'm Shiloh, an 8th grader who's doing a research project about a country from Southeast Asia, and I chose Vietnam. We needed to study a public health issue there, and mine is liver cancer. I made questions to ask for people related in this field and has seen the impact in Vietnam or globally. To anyone is interested in answering, I would be glad!
