What is wrong with Alex Trebeks left hand?

Alex Trebek, the beloved host of "Jeopardy!," experienced health issues related to pancreatic cancer, which he was diagnosed with in March 2019. During his treatment, he occasionally showed signs of physical discomfort and weakness, including in his left hand. This was likely a result of both the cancer itself and the side effects of the treatment he underwent. Trebek passed away in November 2020, but he remained a resilient figure throughout his battle with the disease.
