Mexico is becoming a top medical tourism destination for patients from around the world.

Over one million people are expected to travel to Mexico this year for affordable or alternative medical procedures, most hailing from the United States, where healthcare costs keep rising.

Part of the attraction is its unconventional cancer treatments, which are either too expensive to access in patients' home countries or not approved.

Mexico's medical tourism industry generates over 3 billion dollars a year, and new clinics and health facilities are currently under construction.

Some medical professionals warn however that patients have to be cautious in choosing their medical facility, as not all of them are up to international standards.
