→Hardin Jones, Jones H.B. and cancer therapy
Citations of Hardin are linked to a presentation in 1956<ref>Jones H. B. Demographic consideration of the cancer problem. Transactions, New York Academy of Science, 1956, series 2, v. 18, Seiten 298 - 333, PMID: 13312067</ref>, that's more than 50 years ago, when chemotherapy was in a beginning and early state. The article of 1956 contains statistical data related to treated and untreated female patients with breast cancer. Author Jones says in this article: '''It is most likely that, in terms of life expectancy, the chance of survival is no better with than without treatment, and there is the possibility that treatment may make the survival time of cancer less'' (page 331). Jones citates himself articles of the year 1926 and twice of 1927. But even these very old articles (with 651, 100, 64 and 100 cases) contradict his opinion.

These studies were not modern studies with a control group. According to Jones the death-rate in case of cancer would remain constant over time (''the death rate for all kinds of cancer remains nearly fixed from the moment when cancer is identified'' (page 314). This theory was also known as "The Hardin Jones Principle" and was cited by Linus Pauling in 1989. However, it is known today, that this simple theory is no more valid. Different cancers have their own and different curve od survival.
The description given by Jones is false, if it would be related to our times. At the end of the fifties, 25% of all breast cancer patients were still alive after 5 years. In industrialized contries of today this cipher amounts to around 80% (USA, year 2003)<ref> Jemal A, Thomas A, Murray T, Thun M. Cancer statistics, 2002.
