As Spirit put it, don't put your eggs in one basket. You need to open up all the healing channels and get them all firing in the same direction.
Along with cleansing and flushing, I would add colonics,
juicing organic vegetables, eating as much raw food as possible, eliminate all white flours and sugars and meats and dairy, consider some electro therapies such as zapping and the Beck protocol (pulsing and blood electrification), and very importantly, oxygen treatments such as hydrogen peroxide an/or ozone therapy.
With any cancer it is very important to return the body to a state where it can do its own healing. You do this by supplying nutrients, cleaning out toxins, oxygenating the system, and returning the body to an alkaline state (cancer thrives in a low oxygen, acidic environment). If you change the biological terrain to one which supports health instead of disease, then the body will do the rest.
The mind/body connection is also very important. Guided imagery techniques are helpful and also stimulation of positive emotions. A good way to do this is to rent a wack of comedys and immerse yourself in a humorous, happy mentality. This stimulates the body to release healing hormones.
Pay special attention to lymph drainage. If this highway is stagnent, then debri piles up and cannot be disposed of. Rebounding is the best way. Someone can lightly bounce a very sick person on a rebounder. This is done with the sick person sitting on the rebounder with the helper standin up and lightly bouncing. Also skin brushing is another useful way to move lymph. Then there is also lymph massage, best administered by a trained person.
Water is also very important. In a situation where an acidic condition is predominant, I would utilize alkaline water. At the very least I would use a water such as Penta water which will easily permeate the cells pulling nutrients in and toxins out.
Last but not least is hot/cold hydrotherapy which stimulates microcirculation. 3 minutes hot then 1 minute cold for as many repetitions as possible. I would do this 3 times per day.
All these things work together. Bottom line is the toxic buildup is not getting out quick enough so a breeding ground for disease/cancer has taken hold. The above techniques help to correct this situation.
If it was me, I would forgo any allopathic (hack and burn) treatments) and go with a natural approach. This causes terrible damage and is in no way helping the situation. I beleive it only makes it alot worse.
Good luck, what ever you decide.
