In September 2015, Monica was diagnosed with breast cancer, which was already in the middle stage. Monica was an identical twin, and her 38-year-old sister Erika had also had regular mammograms and ultrasounds without ever detecting cancer. In Monica’s left breast, a tumor had grown to be the size of a tennis ball, and the cancer cells had spread to her lymph nodes.These twins share the same genes, so why did one develop cancer and not the other?We have always thought that it is the genes , our DNA, that determine everything about us. In fact, there is another decisive...

Researchers at Case Western Reserve University School of Medicine have discovered a mutant form of the gene, Chk1, that when expressed in cancer cells, permanently stopped their proliferation and caused cell death without the addition of any chemotherapeutic drugs. This study illustrates an unprecedented finding, that artificially activating Chk1 alone is sufficient to kill cancer cells. "We have identified a new direction for cancer therapy and the new direction is leading us to a reduction in toxicity in cancer therapy, compared with chemotherapy or radiation therapy," said Dr. Zhang, assistant professor, Department of Pharmacology at the School of Medicine, and...

<p>An international team of scientists believes it has found cancer's master switch with the discovery of a gene they dubbed ``Pokemon.''</p> <p>Like the electronic game figures -- tiny monsters with bad tempers -- the cancer-triggering gene apparently instigates the misbehavior of other cancer-causing genes, leading to tumor formation.</p>
