My son has liver cancer also. He did not eat properly for 3 years. He was very tired; slept alot. Started him on colladial silver. He said, thank you, thank you for sending it to me; he now has energy. It works on the imune system. He is also drinking eassiac tea plus taking mineral supplements. It is helping. You can order silver from:

Check on the internet re: tea made from herbs; recipe originally from canadaian indians and then a nurse from canada who helped people. My father-in-law drank it for 6 months and now does not have any lung cancer. My son says the minerals also help to give him energy. Got them from utopiasilver also. I believe my son's immune system is very low from his not eating properly. These listed above are helping; prayer chains are in constant prayer for his recovery. Hope this helps.God be with you and your brother during this difficult time.
