Hi Ammit, I'm very sorry your family could be faced with the possibility of something like this but remember, there's always hope. I did some research and I would recommend (in any order)
Look on youtube the videos from Dr. Tulio Simoncini "Cancer is a Fungus" and definitely the person should try Sodium Bicarbonate
Look the videos Run for the Cure - Hemp Oil
Dr. Johana Budwig protocol - Cottage cheese and flax seed
Any diet conducive to alkalinize the body, cancer can't survive in an alkaline environment, very easy to do with juicing: sparagus and other superfoods, juicing is a delicious way to get healthy very fast and very effective
I highly recommend this web site to everybody, it's all about testimonies from people who have used different cheap home remedies for all kind of ailments and they tell you how they did it:
www.earthclinic.com
I don't recommend Dr. Hulda Clark because her method is way too extreme, usually the person loose all his/her teeth trying to kill ANY virus, parasite, etc., in the body which is almost impossible, there are easier aproaches.
Please let us know any results, it's something we'd be very interested in.
