 We find that many of our patients are impacted by a new type of cancer, something that is the human papillomavirus associated cancer. The HPV virus is a sexually transmitted virus that almost every adult is exposed to at some point when they have a sexual relationship with a partner. And for reasons we don't have great answers for, when some individuals are infected at the earlier part of their lives, that virus can ultimately be harbored in their throats or other parts of the body for decades almost. Decades later sometimes these viruses can convert to a cancer. And these cancers very frequently present in the head and neck, specifically the tonsil or in the back of the tongue. And that HPV associated cancer has now become the most common type of cancer we see. Throat cancers fortunately have a very good prognosis when they're virus associated. And it's now our responsibility to not only achieve an excellent cure rate for our patients, but to offer them a treatment with the least amount of side effects. Quite often robotic surgery is a great fit for many of my patients, but understandably a lot of my patients would also benefit from other treatment alternatives. And it's my responsibility to make sure that I don't operate on my each patient I see, but to really find the treatment option that has the least amount of side effects for them. We hopefully prevent these cancers from never happening. And that's the reason why we're offering vaccines to many boys and girls before they have a sexual relationship. And my goal and my hope is that this cancer does not exist for us in decades down the road. But for right now it is one of the fastest rising cancers in the United States.
