Question: Is there a specific cancer that is most dangerous to humans? If so what is it?

The cancers that are most dangerous to humans are ones that don’t have any symptoms until it’s too late. This includes things like pancreatic cancer and ovarian cancer. Because people have no symptoms the tumour can keep on growing hidden in the body. It’s only when the cancer starts to spread to other organs that people get symptoms and get sick and often then it’s too late to try and kill the cancer. We are trying to find ways to detect cancers early. If we could do a blood test every few years that could look for signs that someone has cancer, or might get cancer soon, then we could stop these cancers from growing in the first place.
