A '''cancer diet''' is a way of alimentation or diet intended to heal or cure a cancer disease in a causal way or to prolong survival time. A wider understanding of the term "cancer diet" also includes a diet intended to improve the quality of life of cancer patients without affecting prognosis.

So far, specific cancer diets are not accepted in scientific medicine, and are common in an environment of alternative medicine. However, most cancer patients choose also concomitant alternative therapies to an effective therapy in a complementary way.

Specific cancer diets are nutritional recommendations going beyond generic recommendations and usually include unusual components, for instance the consumption of herbal substances, or prohibit a particular way of alimentation or particular substances. The recommendations found (in books or the internet) as a rule are backed only by theoretical considerations and usually lack any scientific proof or literature.

The various cancer diets are very different from each other and contradict each other. Alleged preventive effects are often mixed with a possible curative approach.

No specific cancer diet has been accepted by evidence based medicine so far. To the contrary: a one-sided and limited diet (as macrobiotics in its extreme form) may be harmful and cause nutritional deficits and may increase weight loss.
