Stage 1B pancreatic tail cancer - surgical removal, now chemo

On Dec 9, 2025 I had an unrelated CT chest test for cardiac reason. It identified a mass in my pancreatic tail. A 4 cm mass. I had a CT chest exam four years ago and mass was not there. On Dec 11 I had an endoscopy. It was diagnosed to be cancer (the bad type - one that begins with an A). On Dec 16 I had a CT abdomen exam, which showed no spread to other organs, no spread to lymph nodes, no spread to vascular. My CA 19-9 test was 232. My CEA was 2.1

On Dec 24 I had robotic surgery. My pancreatic tail and spleen were removed. The tumor tested during surgery had negative margins. I went home on Dec 27. Surgery recovery has been good. A month later I am walking 8,000-10,000 steps a day. Appetite is normal. Very little discomfort.

I had Oncology appointment this week. My blood work - CA 19-9 was now 7.7. Glucose was 113. All other blood work normal. Post surgery pathology showed no cancer in 21 lymph nodes and being stage 1B. Tumor showed no abnormality for genetics

The oncology recommendation was 6 months of preventative chemo. The aggressive chemo FloroFox. 2X a month. It starts Feb 3. It somewhat scares me given the bad stories you read about it. But given my good fortune so far with such a bad cancer I want to do whatever I can to have a reasonable good future.

I am 65 years old. Walk/exercise every day. Never have smoked. Never drank. Doctors said my health should help
