Using Strength Tests to Better Understand How Pancreatic Cancer Affects Muscle Mass and Quality of Life

The goal of this clinical trial is to measure hand grip strength in adults with pancreatic ductal adenocarcinoma (PDAC). The main questions it aims to answer are: * Is it feasible to measure hand grip strength as part of a clinic visit? * Are changes in hand grip strength related to changes in body composition? * Is hand grip strength related to a person's well-being? * Is hand grip strength related to how a tumour responds to treatment? Participants will squeeze a device with their hand to measure their hand grip strength and complete questionnaires about their well-being when they are seen in clinic for their regular medical care for PDAC.
