Now, to promising medical news in the battle against cancer. Doctors successfully treating cervical cancer by boosting the body's immune system to fight the disease. Two women are alive, today, thanks to the new treatment. Let's bring in Dr. Jennifer Ashton. We really wanted to talk about this. What is this treatment about? How does it work? Big news for gynecology, robin. It's important to remember that most cases of cervical cancer are caused by HPV. Normally, our body's immune system fights off that virus. In this case, the key players were t-cells that took part of the cervical tumor out. They found t-cells from the women who were specified just for that tumor. They multiplied them, boosted them and got them ready to fight and attack. Reintroduced them to the patients. And in two women, they saw the tumor attacked. Extremely promises. How can this be used to fight other cancers? This is the future in cancer therapy. And we're starting to see it even today. It's personalized, targeted therapy, that just attacks the tumor and doesn't do damage to the rest of the healthy tissue. This is an incredibly small trial. This study being done by the national cancer institute. We need larger Numbers. And will this work on other kinds of cancers? You bring up HPV. We see that the fda approved it to be the first line test against cervical cancer? That's right. HPV changes the cells on the cervix. Is HPV there before the cells have changed? Most women, age 25 to 65, should ask for the test. How excited about this are you? Very. It is a great day. Dr. Jen Ashton, thanks very much.
