There are two natural cures that are rumored to be quite effective that would be simple to try.

One is eating 25-50 apricot seeds per day. You can order them on Amazon. Read G. Edward Griffin's book, "A World Without Cancer" about this cure.

You could also have her try eating a raw garlic clove smashed on a buttered slice of Ezekiel bread with grated fresh habanero pepper on top two times a day. This is also reported to work well. Read Kelley Eidem's book "The Doctor Who Cured Cancer" about this method. (Dr. Revici)

I would also have her doing some light fasting and replacement of any bad meals that are not nutritious with juices made in a juicer from a combination of fresh apples, carrot, kale, celery, etc.
