Pancreatic cancer scares the bejeebus out of me. One day I hope there's some solution because it's almost a death warrant if you get that diagnosis.
A bionic pancreas won't help you at all if your native pancreas developed a malignancy.
Cancer doesn't change that - lots of people with cancer get killed by car accidents or heart attacks. In fact a friend of mine recovered 100% from their cancer and then killed themselves on a motorbike.
