At one time, the popularity of these Tijuana clinics was immense.
On my 2011 site visit, I found that the Tijuana clinics are surviving, although most are not exactly thriving.
Since then, the Tijuana clinics have been negatively affected by various geopolitical developments: the terrorist attacks of Sept.
These two articles characterizes the Tijuana clinics as mercenary and dangerous.
But I would like to see ACS data showing that there are "many instances" of this problem or that it is particularly associated with Tijuana clinics. I would say that US patients in general are unlikely to seek out and pay for treatments in Mexico if they do not have the disease to begin with.
In the 2008 article, the ACS authors present 20 or so treatments that they believe are "some of the most common" given at the Tijuana clinics. Their list includes bee venom, cancer salves, shark cartilage, antineoplastons, hydrotherapy, cesium chloride, urea, and live cells from animals.
By and large, this is an unfair characterization of the Tijuana clinics. Almost all now strive for therapeutic as well as economic success.
I was encouraged by the improvement, since my last visit, in quality of the physical plants of the Tijuana clinics. Angeles Hospital and Oasis of Hope come up to standards of American hospitals, and Angeles has applied for Joint Council Accreditation.
