Pancreatic Cancer, from the CureRays guide library.

Pancreatic cancer forms in the digestive gland behind the stomach; it is challenging because it often hides until it grows, but treatments and precise radiation keep improving.

What it is.

The pancreas is a gland deep in the abdomen that makes digestive juices and the hormone insulin. Pancreatic cancer usually begins in the ducts that carry those digestive juices. It is difficult to detect early because the pancreas sits deep inside the body and early cancer rarely causes clear symptoms, so it is often found after it has grown or spread. That said, treatment is steadily advancing — combining surgery, modern chemotherapy, and increasingly precise radiation — and outcomes are better than they once were, especially when the cancer is found while it can still be removed.

How radiation treats it.

Radiation uses focused high-energy x-rays to damage cancer-cell DNA so the cells can no longer divide. The pancreas sits among sensitive organs that move with breathing and digestion, so modern radiation relies on image guidance, breath-motion control, and sometimes real-time MRI to keep the dose on the tumor and off the stomach and bowel. Treatments are painless and brief; side effects can include temporary nausea, fatigue, and appetite changes that the care team helps manage.

The ways we can treat it.

Stereotactic body radiation therapy (SBRT). Delivers focused, high-dose radiation in about five sessions, with motion management to account for breathing and the moving stomach and bowel — useful for borderline or locally advanced tumors.

Chemoradiation. Combines several weeks of radiation with radiation-sensitizing chemotherapy to control locally advanced cancer and sometimes make it removable.

MRI-guided adaptive radiation. Newer MRI-guided machines see the tumor and nearby bowel in real time and reshape each treatment daily, allowing higher, safer doses to the pancreas.

Questions we hear often.

Why is pancreatic cancer often found late? The pancreas sits deep in the abdomen, and early cancer usually causes no clear symptoms. Signs like jaundice, back or belly pain, or weight loss tend to appear once the tumor has grown.

Can pancreatic cancer be cured? It can be, most often when the tumor is found early and can be surgically removed, ideally combined with chemotherapy. Even when cure is not possible, treatment can extend life and ease symptoms.

What is the Whipple procedure? It is the main surgery for tumors in the head of the pancreas, removing the tumor along with parts of the nearby digestive tract and reconnecting them. It is a major operation done at experienced centers.
