Why cancer is so deadly?

Cancer kills by invading key organs (like the intestines, lungs, brain, liver, and kidneys) and interfering with body functions that are necessary to live. Untreated cancer commonly causes death. In contrast, cancer treatment often saves lives – especially when cancer is found and treated early.
