Hi Welcome to HCM
Ihave gone thru your query regarding your father's sufferings due to cancer
of throat & tongue. It is a matter of great concern .
Yes you can apply Accupressure Pls consult a specialist .In my opinion , you should take guidance from an oncologist for actual treatment as the condition of the patient has gone beyond the hands of
Alternative therapies .
Alternative therapies can help you in the begining of the problem & help you strengthening your immune system by following regular life style - proper food habits - intake of fiber , fresh fruit , green leafy veges, vitamins ,minerals all antioxidents as garlic , ginger , onion , in raw form , lot of water Turmeric powder with a cup of hot milk in b/f and at bed time twice and lemon juice with water before meals are anti biotic ,kills bacteria in mass bases and gives resistance to our body from diseases .
Aloe vera juice freash 20- 25 ml twice and coconut water also can stimulate the immune system to produce cancer killing chemicals.
>Regular exercise ,yoga pranayam -deep breathing andpropr, rest ,meditation ect; and avoidance of fried, fast foods , te coffee , alcohol smoking , mental worry anxiety .and constipation , all strengthen our immune system ,helps to lead healthy happy life .
ask him to do gargles with salty luke warm water twice daily to detoxify the system
I suggest ,You can try Magnato therapy treatment is good potant tool of treatment without any side effect goes with any therapy and kills becteria on mass bases If you have any therapist around ,or if you can arranage a set of 2 magnets of SUM 500 power ,inform me.
