According to a recent study highlighted in MIT Technology Review, a team of scientists from John Hopkins University could at this point of achieving a breakthrough in treating breast cancer . The results of their investigations show that the bacteria could help destroy cancer cells in patients with liver cancer, lung or pancreas.
Many doctors and researchers are trying to treat without using therapies such as radio and chemotherapy that weakened the patient. But even new treatments such as the so-called "magic bullet" aimed directly at specific cancer cells have serious side effects.
In its clinical trials, scientists at the John Hopkins injected animals with a cancerous tumor with bacteria that reproduce rapidly within centres solid tumors that lack of oxygen and die in healthy tissues and oxygenated. The researchers were able to destroy bacteria tumors from the inside out, leaving an outer ring of breast cancer cells readily treatable with conventional treatments.
But in addition to accomplish this, the researchers found that in many cases, the bacterial infection "trained" to the animal's immune system to recognize and attack cancer. In 23 of the 70 animals used, the very responsiveness of her immune system destroyed the remnants of the tumor, without need to resort to another type of therapy. Even when the animals were injected with new cancer cells of the same type of cancer, his immune system was able to identify, attack and destruction, this time without receiving injections of new bacteria.
The scientists then experimented with mice and rats, noting the same kind of result could therefore be treated in future apply to humans.
