Whilst this is a very important topic, it is important to emphasis is that there can be a difference between eating to prevent cancer, and eating when you are in treatment for cancer.
Research has shown that a healthy weight, being active and plant-based dietary approaches may help prevent around 30% of cancers, but, once you actually have the disease, it is still not clear to what extent diet can influence its progress or risks of recurrence. This is a growing area of research and more scientific studies are needed before we can fully understand the role of diet and lifestyle in the prevention of cancer after recovery from treatments for the disease.
Hence at this time, the recommendations for Eating Well and Being Active are that, after treatment, people who have been treated for cancer should follow the primary cancer prevention guidelines.
