Can oral sex cause throat cancer?

Timing and intensity of mouth and tongue lick sex may affect the risk of developing oropharyngeal cancer, scientist says:

Skin-to-skin contact (STS) can infect the mouth and throat and cause oropharyngeal cancer, according to a new scientific study published in CANCER.

As reported in the related publication, the researchers found that oral sex with more than 10 oral sex partners was associated with a 4.3 times greater chance of developing  HPV (Human papillomavirus) -related to oropharyngeal cancer. The study also showed that oral sex at a young age and more partners over a shorter period of time (intensity of oral sex) were associated with higher odds of HPV-related mouth and throat (oropharyngeal) cancer.

HPV-related oropharyngeal cancer

Previous studies have claimed that oral sex is a strong risk factor for HPV-related oropharyngeal cancer. So, to examine how behavior related to oral sex might affect risk, Dr. Virginia Drake and her colleagues at Johns Hopkins University invited 163 people with HPV-related oropharyngeal cancer, oral cancer stages, and another 345 without the disease to complete a behavioral survey.

In addition to factors such as timing and intensity of oral sex, it appeared that people who had older sexual partners when they were young and those who had extramarital partners were more likely to develop HPV-related oropharyngeal cancer.

As the incidence of oropharyngeal cancer due to HPV continues to increase, this study offers an interim assessment of risk factors for the disease. In short, we have uncovered additional aspects of how and why some people may develop this type of cancer, which may help us identify those who are at greater risk,” the scientists conclude.

How dangerous could oral sex be for a woman’s health? For a 31-year-old woman, it was almost fatal :

The patient from the city of Alicante, Spain, was rushed to the hospital a few days ago with symptoms of anaphylactic shock.

Looking for the cause of the allergic episode, the girl revealed that she was allergic to penicillin but denied that she received any medication or any unusual food.

The only helpful sign that the 31-year-old had given was that she made oral love to her partner, whose sperm she swallowed, and shortly after that she began to suffer not being able to breathe and also developing rashes.

Doctors ruled out a rare sperm allergy when the woman admitted that none of her previous sexual contacts and sexual relationships had caused any similar symptoms.

The medical team then discovered that the girl’s 32-year-old partner was taking amoxicillin and clavulanic acid – a form of penicillin to treat an ear infection.

As a result, doctors at the hospital suspected that the anaphylaxis was caused by the transfer of amoxicillin through the semen.

Oral cancer does not spread quickly, it has some stages. Doctors use the system to describe the stages called TNM (Tumor, Node, and Metastasis) system. The final result of the TNM system determines the oral sex stages. Oral cancer stages are 4 given below:

Stage 0:

Is the very beginning stage in which skin, liver, lungs, and breasts are affected, this stage also describes oral sex. Oral lichen planus cancer also develops mouth cancer.

Stage 1:

Are the early stage of cancer in which symptoms show and tumors develop in the body but the size of the tumor is not more than 2 centimeters. Single isolated oral cancer black spots on gums indicate the beginning of mouth cancer.

Stage 2:

In stage 2 the size of the tumor is more than 2 centimeters but has not reached the lymph nodes.

Stage 3:

Stage 3 is the most advanced oral cancer stage of mouth cancer the oral cancer stages. In this stage, the size of the tumor is more than 3 centimeters and also reached the lymph nodes.

Oral cancer vs canker sore:

The main difference between them is canker cancer causes pain and oral cancer is not painful. Cankers are sore anywhere inside the mouth and are always flat and have a white center while oral cancer causes tumors in the throat and also oral lichen planus cancer.

The case, believed to be the first on record, was published in the British Medical Journal Case Reports.

A new study shows HPV vaccination has led to a 51% reduction in diagnoses of cervical precancerous lesions among 15- to 19-year-old girls:

HPV vaccine

The HPV vaccine seems to work. Vaccinating girls mainly against the human papillomavirus (HPV), which causes cervical cancer, has already been a major success, significantly reducing infections worldwide, according to a new study that assessed global progress so far.

Vaccines have prevented many infections that could lead to cancer, which is expected to show in the statistics in the coming years. Experts consider it realistic that in a decade the incidence of cervical cancer will have decreased significantly internationally and, in a few decades, in some developed countries it may even have zeroed out.

HIV Transmission

The researchers from Canada and Britain, led by Melanie Drolet of Laval University in Quebec, who published the relevant publication in The Lancet, evaluated data on about 60 million people, based on 65 studies in 14 countries over an eight-year period. HPV vaccines were launched in 2007 and have since been adopted in approximately 115 countries.

HPV is transmitted through sexual activity and can also cause precancerous lesions and genital warts. The new study found that vaccines have reduced the incidence of warts in girls aged 15 to 19 by 67% and by 54% in women aged 20 to 24, but also by 48% in unvaccinated boys aged 15 to 19 and by 32% in unvaccinated men 20 to 24 years of age. This suggests that HPV vaccines also benefit broader unvaccinated groups of the population, as the immunity of vaccinated girls and women also protects unvaccinated boys and men to some extent.

Also, the study shows that vaccinations have led to a 51% reduction in cervical precancerous lesions diagnoses among 15- to 19-year-old girls.


According to the World Health Organization, approximately 570,000 new cases of cervical cancer were diagnosed in 2018 and there were 313,365 deaths from the disease, making it the fourth most common cancer among women worldwide. The vast majority of deaths (80%) are in poor countries, where vaccination is low to non-existent. About eight in ten developed countries have HPV vaccination programs, but only two in ten low- and middle-income countries. Vaccinating boys, in addition to girls, is expected to further help combat the virus. But in some European and other countries, the anti-vaccination movement has instilled fears and doubts, which have led to a slowdown in vaccinations.
