No. Coconut oil is not proven to fight cancer or kill cancer cells in the body.
Some people do find coconut oil easier to tolerate during treatment. It contains a special type of fat called medium-chain triglycerides or MCTs. These fats can be more easily digestible.
However, coconut oil does not have any research-proven, cancer-fighting effects.
Because coconut oil contains MCTs, some people rely on this fat for extra calories during cancer treatment.
If a person has malabsorption due to cancer treatment, they should not use coconut oil. Instead, they will need an MCT-based medical nutrition product.
