When is radiotherapy recommended for pancreatic cancer?

A specialist team considers whether the tumour can be removed, where it sits in relation to nearby blood vessels and organs, and whether it has spread. Radiotherapy can be given before surgery to help make an operation possible, alongside medicines as part of a planned course, or after surgery when the team believes treatment could reduce the chance of cancer returning in the treated area. When surgery is not possible, focused treatment may help control growth or ease pain, bleeding, or blockage-related symptoms.

Treatment is planned around the pancreas and nearby bowel, stomach, liver, and kidneys. The team may use scans to shape the beams and protect healthy tissue as far as possible. Side effects can include tiredness, skin changes, nausea, or bowel symptoms, depending on the area treated.

Bring a list of medicines, supplements, previous operations, and current symptoms to the oncology appointment. Ask how radiotherapy fits with chemotherapy, surgery, nutrition support, and pain control. Before treatment, planning scans and instructions about meals or medicines may be needed. Tell the team about diabetes, weight loss, jaundice, vomiting, or difficulty eating because these can affect preparation and support.

Contact the treatment team promptly for repeated vomiting, inability to keep fluids down, new confusion, fever, worsening abdominal pain, or yellowing that is rapidly increasing. Seek emergency help for severe pain, fainting, breathing difficulty, heavy bleeding, or signs of dehydration.

Ask whether the aim is to shrink the tumour, improve surgical options, control growth, or relieve a symptom. Clarify the treatment area, schedule, expected side effects, how pancreatic enzyme or nutritional support will be managed, and which symptoms should trigger a same-day call.
