New cancer "curing" medications are announced to the public all the time. Unfortunately, what you are not told is when they will be available. It isn't much use if you have to wait ten years - if you have cancer you could be dead before then.
It is not so much chemicals that attack dangerous "bugs" that are coming to the fore: modified molecules are increasingly being tested. In prostate cancer testosterone attaches to androgen receptors. Activation in this manner allows cancer growth to take place. A helix-mimicking molecule attaches to the particular docking point thus preventing the ideal cancer condition occurring.
In animal and human tests protein supporting cancer growth was not produced when the molecules attached. Moreover, it was not found to be toxic to the body. This research opens up a completely new area of treatment. The future looks bright in the fight against cancer - it we can afford to pay for it.
