So sorry about your father's cancer.
I'm not selling or promoting anything for profit.
Eight grams of curcumin in 4 divided doses (every 6 hours) has actually proven to cure cancer. The FDA even agreed with this.
You should use something with guaranteed curcumin content like "Yarrow Curcumin 95". Take it with Bio-perene. This black pepper extract intensifies the effects of curcumin. This is not always without side effects but you have to battle through them. I get horrendous head aches.
In addition your father needs to get his body PH to 7.0 and keep it there. Since he can't eat well I would suggest using Alka-Seltzer GOLD 3-4 times a day. That's Gold NOT Cold. The Gold contains bicarb and potassium salts. You should use PH test strips to check the PH of his urine 2-3 times a day to know how to adjust dosage. Never put the test strip in your mouth. There are chemicals in the strip that are dangerous. The mouth will not give a true reading anyway.
If you can get Mebendazole (Ebay-India or China)he should take the recommended dosage daily. This drug was on the market in the US for treating pin worms but when they discovered it STOPPED cancer they stopped making it. I imagine it will reappear some day as a miracle cure. But they still make it in India. If you can't get it or there is a long delay in receiving buy Panacur horse paste at a farm store. Depends on his weight, but spread the dosage out over 3-4 doses a day. It works about the same as Mebendazole.
If you have the money buy a Rife Zapper. There are numerous frequency runs for treating cancer. I can tell you from experience that zappers actually work but you need to be careful about what you buy. Walk away from the "Hard Sell" they are just hype. I use a Rife zapper I purchased on the web.
There are numerous other things that help but you need to stop the spread NOW.
-folate 4 times a day....NOT folic acid
-Solgar liver Cleanse.....dirty livers contribute to cancer
-Iodine....Iodoral is expensive but easy to use. Start low and work up to 100MG as fast as he can take it.
-Solgar Ester Vit C. Buy capsules because he can't break down pills. Have him take as much as he can tolerate in 4 divided doses up to a total of 8 Grams daily. (I take more but 8 is the commonly recommended cancer dose) Take the Vit C with Thiamin- high dose again (I take 3 grams). This C plus Thiamin formula was used for decades to cure sepsis (blood poisoning)
has proven to kill cancer. If you get a script it will cost 3-5 US dollars a pill. If you buy from a pet supply or ebay you can get it for about $1 per 100MG. I have not found what dosage is recommended for cancer but I would suggest at least 100mg 4 times a day.
This is just a start. Most importantly..."Attitude is Everything". If he would practice visualizing the cancer disappearing this will encourage his body to heal. This is not snowflake BS. It works.
Hoping for the best for you and your father. My mother refused to listen and died quickly. Everyone thinks Doctors are the answer. The body was designed to heal itself given the appropriate support.
