It has been known since the 19th century that radiation will kill cancer cells. The challenge has been to use radiation effectively while doing minimum damage to healthy tissue. Advances in radiation therapy technology have rendered radiation a much more effective weapon in the battle against many cancers.

In 1971, the U.S. Congress passed the National Cancer Act and devoted millions of dollars to cancer research. Forty years later, that research is bearing fruit as many cancers have yielded to better detection, better treatment, better survivability and better cure rates. U.T. Health Science Center oncologist Dr. William Hyman discusses progress in the War on Cancer in this latest post to HealthConnection.TV.

For what types of cancers has it been the most difficult to improve outcomes? (skip to 1:38)
What do we need to do in order to wage a more effective war against cancer? (skip to 2:00)

As the population ages, cancer rates increase. Why is this so? (skip to 3:11)
Because of improved mortality rates for other diseases, have we statistically increased the chances for getting cancer? (skip to 4:12)

Some have predicted that there will one day be a vaccine for cancer. How likely is it that this prediction will come true? (skip to 6:39)
Will there ever be a cure for cancer? (skip to 7:22)
With advances made in recent years in understanding genetics, it is now possible to administer tests to help determine an individual’s susceptibility to cancer and to possibly ascertain the best courses of treatment for those that have certain cancers. But with this technology comes a list of questions regarding the timing, accuracy and even the ethics of testing individuals for susceptibility to disease. The U.T. Health Science Center’s Dr. William Hyman discusses these issues in this edition of Health Connection.
