Cancer Treatment: Eating, Side Effects and Support
Prepare for food and symptom changes during chemotherapy and cancer treatment, with practical records and clear advice about contacting your care team.
During treatment, a favourite food may suddenly seem unfamiliar, or a small meal may feel like a considerable achievement. Those details are part of care, not a test of determination.
Start your food and symptom diary
Understanding Chemotherapy / Cancer Treatment
Chemotherapy uses medicines to treat cancer. Other cancer treatments have different purposes and side-effect profiles. Chemotherapy can cause nausea, mouth soreness, bowel changes and tiredness, but the effects depend on the treatment and person. [1]
Care and everyday food decisions
Ask your oncology team which symptoms to expect, how to use prescribed supportive medicines and when to call urgently. Eating and drinking difficulties deserve help early. Discuss supplements with the team rather than assuming that a 'natural' product is suitable during treatment. [1]
Keeping a useful personal record
Keep treatment dates alongside what you could eat or drink, bowel changes and prescribed symptom medicines. Record the problem plainly, such as 'mouth sore; cold yoghurt easier than toast'. One Food Forward can help you explain a pattern at review, but it does not check blood counts or monitor treatment safety.

Should I wait until my next appointment to report side effects?
No. Follow the team's contact instructions when a symptom concerns you. A diary can support the conversation after you have sought help; it should never delay it. [1]
Keep the details somewhere you can find them
There is no need to tell the whole story at once. Start with today’s meal, a symptom or a few words about how you felt. Those small entries give you something to return to when it is time to talk about your care.

Your healthcare team should guide diagnosis, treatment and changes to your diet or medicines.
