Yes, especially when (and after) he is actively having treatment.
Good fields for your friend:
*Increased Nutrient Absorption- listen to after each meal
While the patient is undergoing chemo and/or radiation, best to avoid any antioxidant fields (including Vit C) since it can interfere with killing off the cancer cells.
Look into fields for your friend that will increase his energy and life force. Fields like Jing, etc. Another thing he can do is use a water charger that does this also.
Just carefully read descriptions of fields and if they are strongly or moderately antioxident based, best to hold off for now.
Since H&N (Head & Neck) cancers usually dont spread to the kidneys u can include a field to support the kidneys since they are one of detoxification organs. H&N cancers do spread to the liver.
And the bad news which I debated to myself to include, but when I read untrue info about serious medical concerns I find it hard to hold back and ignore.
When a patient is correctly staged with a cancer, then that is their stage that they are at. Even if surgery/chemo/radiation or any other treatment shrinks or eradicates the primary tumor(s), or its metastasis (spread) they would perhaps be considered in remission, but not restaged .
(Sorry, I keep adding more info to this post as it pops up in my mind.)
I would focus on the SM Anti-cancer field primarily.
Plus the other fields and types of fields I mentioned.
Make sure he doesnt get drained from them.
Encourage him to eat/drink small frequent mini-meals and snacks.
Also one of my favorites
*Senescent Cell Removal
