The Oasis of Hope Hospital is a clinic in Tijuana, Mexico providing alternative cancer treatments to its customers.[1]

Many of the treatments offered there have been found to be ineffective, and criticized as quack remedies; the clinic itself has been characterized by Quackwatch as "dubious".


In 2005 Ralph Moss, an advocate of alternative cancer treatments, published an article giving something of the clinic's history. He wrote that it was formerly known as the Del Mar Medical Center and Hospital and was run by Ernesto Contreras who oversaw its expansion to accommodate customers from the United States; new English-speaking staff had been hired especially to cater for this client base. According to Moss, despite the fact that the American Cancer Society had put Ernesto Contreras on a list of practitioners of "unproven methods" in 1971, the clinic claimed to have had 40,000 American customers in the 40 year prior to 2005.[1]

After Ernesto's death in 2003, running of the clinic passed to his son Francisco Contreras and Daniel Kennedy,[1] who is Francisco's nephew.[2]


Between 1996 and 1997 sociologist David Hess[3] conducted an interview with Francisco Contreras which covered many aspects of the Clinic's operations. Contreras said that Metabolic therapy was the main offering of the clinic, and was made up of four steps:

Another therapy was called the "Warburg" therapy named (according to Hess's account) after Otto Heinrich Warburg. This consisted of:

Hess also wrote that Contreras cited a number of non-physical aspects to the clinic's therapy, including religious assistance, psychology and singing and laughter sessions – Contreras claimed that people with strong spiritual beliefs recovered better, and that laughter stimulates the immune system.[4]

In 2005 Ralph Moss reported that the clinic was using amygdalin and the Issels treatment.[1] In 2011 Moss wrote a further report on the Tijuana clinics, and noted that their ability to attract custom had been diminished by the publication of research showing that amygdalin was not effective, by tougher regulation arising from the 1994 North American Free Trade Agreement, and from Tijuana itself become a less desirable destination as a result of a decline brought on by the war on drugs. Moss also noted that some American hospitals now had alternative medicine offerings, diminishing the distinctive appeal of the clinics in Tijuana.[5]

In 2005, The Guardian reported the case of a man with cancer who paid US$40,000 for a one-month treatment in which he had high-fevers induced in the belief that the heat would kill his cancer cells.[6] In 2010, the weekly cost of attending Mexican border clinics, such as the Oasis of Hope, was reported to be between US$3,000 and US$5,000.[7]


Amygdalin (sometimes called "Laetrile") is a toxic glycoside. A systematic review of 2015 found "the risk–benefit balance of laetrile or amygdalin as a treatment for cancer is [...] unambiguously negative".[8]

Issels treatment is a regime normally recommended to be used alongside conventional treatment. It requires removal of metal fillings from the patient's mouth, and adherence to a restrictive diet, supposedly to aid in cancer treatment. Cancer Research UK have said of it: "There is no scientific or medical evidence to back up the claims made by the Issels website".[9]


According to Quackwatch, the Oasis of Hope Hospital is a "dubious cancer clinic".[10] Richard Sullivan of Cancer Research UK has said, "the Tijuana clinics are essentially set up to deceive and it's a disgrace."[6]

Barrie R. Cassileth commented on a small longterm follow-up study that had been carried out on patients of Mexican clinics, including those taking the Contreras treatments. She said that most patients did not know what stage their cancer was at, but that the mean survival time – of 7 months – was enough to conclude that "Contreras therapy is ineffective in treating late-stage cancer patients".[11]

The Memorial Sloan-Kettering Cancer Center lists "Contreras Therapy" alongside other alternative nutrition-based cancer treatments like the Gerson Therapy which "show no evidence of efficacy".[7]
