Laryngeal cancer is more common in men and less in women am730

HPVBreast cancer in men starts with an oral infection.

A 2017 research report from Baylor College of Medicine in Houston, Texas, USA, said that the prevalence of oral HPV infection among American men is much higher than previously thought, with an estimated number of 11 million men.

What about the women? Another study of oral HPV infection in the United States found that, from 2009 to 2010, approximately 10% of American men were infected with oral HPV, while the rate of oral HPV infection in women was only 3.6%

The famous Professor Basu is a professor who specializes in laryngeal cancer in the Department of Otolaryngology at the University of Pennsylvania. Since 2010, he has classified HPV-caused throat cancer from other types of throat cancer and researched diagnosis and treatment. But so far, there are still two main problems that have not been solved:

1. With so many people infected with oral HPV, why do only a small number of people get throat cancer?
2. Why is throat cancer more common in men? The incidence ratio among men and women is 5:1.

In Hong Kong, 81% of new oropharyngeal cancer cases in 2021 are men.

Even if you have high-risk HPV infections, not everyone gets cancer.

For most people with HPV, the HPV will go away on its own even without any treatment. This is because the human body will mount an immune response about 3 to 6 months after infection to prevent the growth of the HPV virus in the body Clinically, about two years after being infected with HPV, HPV will go away on its own in almost 90% of cases.

In other words, most people’s HPV infection is temporary, lasting only about 12 to 24 months. In the case of oral diseases, only a small number of men’s immune systems fail to clear HPV in the oral cavity, allowing the virus to continue to cause disease and damage in the oral cavity, leading to cancer finally.

Unfortunately, there is currently no way to screen and predict who will develop cancer after HPV infection. This is the main question. Talk next week.
