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".
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 followup 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]
