My best friend died of pancreatic cancer at 41. By the time he received the diagnosis, it was too late. The cancer had metastasized so extensively that the surgeons could do nothing when they attempted to operate. What began as mild lower back pain led to a slow and agonizing death in just a few months.
That's exactly what happened to my friend's father. He had been complaining about lower back pain for many months and going to physio for it. During a family re-union during Christmas, he had to be hospitalized and got diagnosed with stage 4 pancreatic cancer. One week later, he died.
