This interesting article discusses the idea that while mutated genes may be the main cause of a cancer, the surrounding cellular environment may contribute to the growth of the cancer. In an effort to understand the biology of cancer and its growth, various researchers have looked at novel causes that in the past were rejected by other scientists. Why did cancer cells injected into an embryo fail to continue growing as cancer but, when injected into adult animal tissue, continued to grow as cancer into surrounding tissue. Is the mechanism for this in the cancer cells or in the normal, healthy cells surrounding the cancer?
Although this article is from 2009, it sheds a different light on the thoughts that some researchers believe needs to be shone on this disease in a frustrating effort to pursue other avenues for answers.
