(NaturalNews) One of the world's most lucrative industries, spending on cancer drugs reached an all-time high last year, as it was valued at more than $100 billion. Spending on cancer drugs increased 6.5 percent annually over the past five years and is expected to continue growing at a rate of 8 percent each year through 2018, according to figures provided by the IMS Institute for Healthcare Informatics.That spending is highly concentrated, as the US and five of Europe's largest countries account for nearlyof the entire market.This means thatare secured by Americans being diagnosed with cancer.That's one profitable industry; however, it could all be completely dismantled by one thing: a cure.As Mike Adams recently reported , "A universal cancer cure would destroy the profitability of the highly lucrative cancer industry and collapse the American Cancer Society, hospitals, oncology clinics and pharmaceutical companies that depend on chemotherapy revenues to stay profitable."This means that anyone moving closer to developing a cure for cancer would be considered anthreat to the medical establishment and likely stopped atcost.With that in mind, the mysterious deaths and disappearances of several natural health doctors throughout Florida is as suspicious as it is concerning.If anyone was close to finding a universal cure for cancer and would ensure the public had access to it, it would likely be natural health doctors, or naturopaths, as they're less likely to prescribe drugs and more likely to try and heal the body naturally using holistic medicine and nontoxic approaches.Breakthroughs using this type of medicine are extremely "controversial," as they threaten everything that the medical-industrial complex stands for, i.e. costly chemotherapy treatments and cancer drugs.Doctors leading this type of research are routinely raided and shut down by the U.S. Food and Drug Administration (FDA), after which they're treated like criminals and their reputations smeared.This is typically orchestrated against doctors who are considered a threat by the medical establishment.This seems to be the case with Dr. James Jeffrey Bradstreet, who was recently found dead after his body was discovered floating in a North Carolina river with a single gunshot wound to the chest. Bradstreet, a renowned physician known for his skepticism of immunizations (particularly the MMR vaccine), and his progressive autism research, was raided by the FDA one week before his mysterious death. The details of the raid remain largely unknown.Personally affected by autism, as both his son and stepson were diagnosed with the condition, a significant portion of Dr. Bradstreet's work was dedicated to this cause. He even testified twice before the U.S House of Representatives about the link between vaccines and autism.As' reported, leading up to his death, Dr. Bradstreet was working with a little-known molecule that occurs naturally in the human body. GcMAF (Globulin component Macrophage Activating Factor), which is the GC protein after it combines with vitamin D in the body, has the potential to be aIt's also believed to be capable of treating and reversing autism, HIV, liver/kidney disease and diabetes.In an interview on the, Dr. Ted Broer, an internationally recognized health and nutrition expert also based in Florida, describes how cutting edge Dr. Bradstreet's work was, as well as aand could have been the motive for his suspected murder.The alternative doctors who went missing and/or were killed, were reportedly "interlocked" through Dr. Bradstreet and Dr. Gonzalez's extensive research on autism, and what's causing autism, according to Dr. Broer.Dr. Gonzalez, a renown holistic cancer treatment pioneer who helped thousands overcome the disease through alternative medicine, died of an apparent heart attack just one month after Dr. Bradstreet's body was discovered floating in a river.Dr. Broer stated in the interview:After defining GcMAF and how it's formulated, Dr. Broer reiterates that it's "probably the single most effective thing in the immune system to kill cancer cells."However, what Dr. Bradstreet and his colleagues discovered is that the immune system is being compromised by a compound called "nagalase."Nagalase is an enzyme/protein that's made by cancer cells and viruses causing immunodeficiency syndromes and has also been linked to autism as well as a "host of other problems," Dr. Broer explains."What ends up happening is when the GC protein cannot be converted to McGAF, the entire immune system is compromised."Some of the doctors who wound up dead or missing"This is such incredibly damning information to the entire medical profession and the immunological profession and those folks that [] are producing immunizations, that apparently they didn't want these guys around," Dr. Broer said."I'm not saying what happened to these guys, I'm just saying they're not on this planet anymore."Nagalese blocks the GC protein from attaching itself to vitamin D, thus preventing the immune system from doing its job and therefore causing cancer and other serious diseases. Without an active immune system, cancer and viral infections can spread rapidly.Remarkably, there's a significant amount of research available on nagalase and the GcMAF protein. Citing a chapter fromby Dr. Tim Smith, MD, Dr. Broer said:Dr. Bradstreet and his colleagues also learned that the nagalase protein was not present in children at birth but was somehow introduced into autistic children, they felt, during the immunization process.Before his death, Dr. Bradstreet treated 1,100 patients with GcMAF with an– something that was deemed impossible by the medical community.After reintroducing GcMAF (which had been blocked by nagalase),, as all of their symptoms wereeradicated.Since 1990, 59 research papers have been published on the healing effects of GcMAF, 20 of which pertain to the treatment of cancer. Research suggests that GcMAF can also cure or effectively treat Parkinson's and Alzheimer's disease and rheumatoid arthritis, as well as reduce cancerous breast, prostrate and kidney tumors.Stay tuned ascontinues to uncover more on this investigation.
