Unproven or fake cancer treatments are offered to desperate patients around the world. Eminent cancer expert discusses how to be vigilant in seeking cancer therapy. Many cancer patients around the world are offered unproven cancer treatments. Bad cancer therapy is advertised as "safe and might work". Dr. Anton Titov, MD. Such treatments are sometimes approved locally. Approval is done by a less rigorous process than the US FDA has. Dr. Anton Titov, MD. What can help patients to make better judgments about cancer treatment options? How to find effective cancer medications? Dr. Bruce Chabner, MD. The kind of things that you are doing can help. Going to the internet and seeking public sources of information are very important. You are correct. Worldwide there are different criteria to approve cancer medicines. Different cancer medications are available to patients living in different countries. Some of the cancer medicines we have here are not available overseas. Others anti-cancer medications are not used here. It is true particularly in the field of immunotherapy, for example. Sometimes you go to Cuba. You get a very heavy emphasis on cancer immunotherapy. Dr. Bruce Chabner, MD. We think some cancer immunotherapy is unlikely to work. It may detract a patient from getting the correct cancer treatment. Immunotherapy may move you away from the appropriate treatment. So yes, cancer treatment cancer medications quality isn't uniform. But here are sources online that tell you what the appropriate cancer treatment should be. I edit a journal “Oncologist". This cancer journal gets a million hits a year. Many of them are from the lay cancer patients. They are looking for review articles. Review articles tell you what the best cancer treatment might be. So that is a very good example. It is how cancer patients around the world are seeking the information. They are trying to get it from several medical experts. Experts work perhaps in different countries. Dr. Anton Titov, MD. Different sources of information about cancer therapy can hedge your risks of getting the wrong treatment. They help to not be distracted by cancer treatments that might not be effective. Ineffective. Dr. Bruce Chabner, MD. Correct, exactly!
