Cancer is not one disease is an animated short documentary that draws on the experience of a patient living with pancreatic cancer, raw scientific data and visual effects to show some of the complexities of cancer. Over a long period of time, molecular ‘mistakes’ can accumulate in a cell, which increases the risk of cancer. There are thousands of molecular mistakes that can occur in cancer and every cancer is unique. Now, these specific mistakes can be detected in individual cancer patients, which is providing new hope for the future of personalized cancer treatment.
