Cancer is a process that has always effected animals, it is just as common in domestic and farm animals, birds and fishes as it is in humans. Western scientific medicine has been effective in minimising infectious diseases. Many of us are living longer and cancer has almost been accepted as a normal feature of the ageing process. But statistics do not bear this out. The incidence of cancer is increasing in all age groups.

Because cancer cells take some time to grow to a stage where they are a large enough mass to be identifiable, it might be 18 months to 3 years, even 30 years before the disease is diagnosed by a doctor. By then we can be more than half-way down the path to a terminal illness. Due to our psychological make-up we are often immobilised by the news.

We tend to minimise it or deny that it has happened to us. We get depressed.
