If you have DCIS, experts such as Dr Samuel Epstein, a world authority on cancer, favour the watch-and-wait approach, then frequent monitoring; only consider treatment if it turns into true cancer. If it does, many alternative treatments are highly successful. The following are recommended by the US charity People Against Cancer (www.peopleagainstcancer.com):
A strict wholefood, unprocessed diet
* Exclude sugary and fatty foods, dairy products and wheat
* Include an intensive nutritional-supplement programme: high-dose vitamin C, beta-carotene, vitamin B-complex, selenium, zinc, coenzyme Q10, fish oils and vitamin B17 (apricot kernels).
An intensive detoxification programme
* Eliminate mercury from amalgam fillings and from anywhere else in the body. Most cancer patients have high levels of this heavy metal
* Coffee enemas, which will stimulate the liver to excrete toxins.
Gentler anticancer therapies
* Short-term high-dose hormone blockers. Dr Axel Weber, in Bavaria, gives the hormone-blocker busarelin at 20-40 times the usual dosage for no longer than 12 weeks. This is one of the more promising regimes, says People Against Cancer
* Intravenous hydrogen peroxide
* High-dose vitamin C treatment offers at least a 16-fold increase in life expectancy (J Ortho Med, 1990; 5: 143-4)
* Heat therapy (hyperthermia) applies heat to the breast-cancer tumour using highly focused radiowaves, raising the tumour temperature to about 44 degrees C. This kills cancerous cells, but not healthy ones
* Infusions of laetrile (the anticancer compound derived from apricot kernels) and/or melatonin (an antioestrogen)
* Ozone therapy enriches the patient's blood with ozone to 'activate' the red and white cells, stimulating the immune system to cure itself
* THX/Thymex-L, a thymus extract believed to boost the immune system
* Low-dose interleukin-2, an immune booster, with or without antihormone therapy
* Immune augmentation therapy, in which anticancer 'immune complexes', harvested from the blood of healthy donors, are infused into the cancer patient
