Medical News today reported the results of a study showing DHA’s role in reducing tumor size:

Docosahexanoic acid (DHA), an omega-3 fatty acid found in fish oils, has been shown to reduce the size of tumours and enhance the positive effects of the chemotherapy drug cisplatin, while limiting its harmful side effects.

Ever since a case report was published in the journal Nutrition and Cancer in 2005 in which an elderly man with a large and inoperable lung sarcoma went into complete remission with high dose fish oils, predominantly DHA, I’ve been emphasizing DHA (and vitamin D) in my nutritional recommendations for people facing cancer challenges.

In the case report, the intake of EPA+DHA was in the range of 15-18 grams per day, about the amount that the Innuit on their traditional diet of seal, fish, and whale blubber used to consume. That’s a lot of omega 3, and should be supervised by a nutritionally knowledgeable physician, but even 4-6 grams per day, especially with a high DHA product can be a big help.
