Homeopathy has been very effective in prevention of cancer. I have seen patients who were supposed to have the cancer back in 3-5 years live for much longer without any relapse.
Mostly importantly because homeopathy treats the person and his/her causes. The patients recovers very soon from the side effects of treatments and the effects of cancer on them.
The quality of their life and the quantity is hugely improved by a holistic method of treatment. With homeopathy all the causes at genetic , physical and mental level are addressed. No cause at any level is left unaddressed this ensures no relapse and better health, well being of the patient.
