There is a theory stating that perhaps the cure for cancer has already been found. Yet, a lot of people in the medical world know that most of their revenue is from the cancer treatments and medications that they provide to their customers.
If the right drug would be offered to human beings and people can be cancer-free, then they may not make the same amount of money anymore. Of course, this is just a theory. There are still a lot of doctors and medical professionals whose main goal in life is to save as many people as they can from various diseases. There are still a lot of people who wish that Cancer can be cured for good.
