Everyone’s nutritional needs will be different when diagnosed with cancer. Some people will feel well and be able to eat normally. For others, weight loss or a poor appetite may have been symptoms that led to their diagnosis. If you had eating problems before you were diagnosed, you may need some support from your doctor or dietitian. They will try to improve your food intake before you start treatment.
Some eating problems may be related to the cancer itself. Depending on where the tumour is in your body, it can make you feel sick (nausea), be sick (vomit), or it can cause pain or poor digestion. The tumour may also change the way your body uses the food you do eat, so that you don’t get all the nutrients you should.
