A rise in HPV which can cause throat cancer if contracted during oral sex may be responsible for rising rates of the cancer. The dramatic rise in the virus over the course of the last two decades led the American Association for Cancer Research to call a meeting to discuss new research into HPV and its link to throat cancer. While tumors tested twenty years ago had HPV levels of about 20% current samples have a much higher rate 60% which is the reason for concern. It’s believed that because of the changing beliefs on sexual practice and interaction HPV may have become a more serious problem, potentially causing higher risk for developing head and neck cancer, including esophageal cancer. While it was once a problem primarily found in older people who drank and smoked now these cancers are being found in younger people. Part of the rise of oral sex is believed to be linked to a belief that it is safe sex, the reality is that oral sex should require protection as much as penetration as it leaves those who practice it open to just as many diseases including AIDS as intercourse.

Waiting a few minutes before drinking your hot tea may be more than simply avoiding a burnt tongue; it may even be a way to prevent throat cancer. A new study carried out in Northern Iran, where large amounts of hot tea are consumed on a daily basis, established a link between drinking very hot tea and an increased risk for cancer of the esophagus.
Hot is defined as having a temperature of 158°F (70°C), usually the temperature of freshly boiled tea. The study was published on the website of the British Medical Journal. The findings are not really meant to cause alarm, though; the general advice is to wait a little bit and allow foods and beverages to cool down before swallowing.
The esophagus is the muscular tube that carries anything that is taken in through the mouth – such as food and beverages – into the stomach. Cancers of the esophagus claims the lives of more than half a million people annually. The most common type of throat cancer is esophageal squamous cell carcinoma (OSCC). The main cause of throat cancer in Europe and America is the use of tobacco and alcohol, but consuming hot beverages has also been thought to be a risk factor. Throat cancer is more common in men than in women.
The study was conducted in the Golestan province in Northern Iran, where there is a high incidence of OSCC but low rates of smoking and alcohol – the two most common risk factors. Women also possess the same risk factor as men. This led to the hypothesis that the consumption of hot beverages may be a third risk factor.
The results of the study showed that those who drank warm of lukewarm tea (149°F or less) and hot tea (between 149°F to just under 158°F) can be associated with a two-fold risk of esophageal cancer, while those who drink very hot tea can be associated with an eight-fold risk.
Don’t let this dampen your hot beverage drinking regimen, though. It is simply suggested that we wait about four minutes to allow food and beverage to cool down before swallowing.
