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

The Guardian reported in 2005 that the reason for the concentration is that most methods used by the hospitals are "discouraged by conventional medical science" and because health regulations aren't as strict as the United States, it is a logical place for them to operate.

More than 60 hospitals, clinics and semi-clandestine offices offer to cure or help control the disease in ways ranging from the unconventional to the controversial.

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.

At the time they were not allowed to publicly advertise alternative cancer treatments in the United Kingdom, so the talk was aimed at raising understanding.

[9] 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.

[1] In 2011 Moss wrote a further report on the Tijuana clinics, and noted that their ability to attract customers 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 have alternative medicine offerings, diminishing the distinctive appeal of the clinics in Tijuana.

"[5] 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.
