Cambridge University Research: The number of sexual partners is related to the risk of cancer.
What is the experience of changing sexual partners like changing clothes? If you overdraft your health due to temporary indulgence, the disease will hide in the near future and give you a fatal blow.
Cambridge University study: The number of sexual partners is linked to cancer risk
In the past, few people paid attention to the potential impact of the number of sexual partners on health, but as more and more cases were exposed, people began to pay attention to the relationship between sex and health.
Seven institutions from the University of Cambridge and the University of Vienna collaborated across a country to conduct a study on the number of sexual partners and the risk of chronic diseases such as cancer.
The study focused on middle-aged and elderly people over 50 years old from England and counted the number and health of their sexual partners. In the end, it was found that the number of sexual partners was positively correlated with the risk of cancer. The more sexual partners, the higher the risk of cancer.
According to research data, compared with women with 0 to 1 sexual partners, the probability that 10 or more women will be diagnosed with cancer is as high as 91%; among men, 2 to 4 sexual partners are diagnosed with cancer. The probability of cancer is 57%, while having 10 or more sexual partners is as high as 64%.
These types of cancers are closely related to sexual life
People with more active sex lives and more sexual partners are more likely to be infected with HPV (84.6% for women, 91.3% for men) as medical expert mentioned. Once infected with HPV, what related diseases might it cause?
What kind of cancer can the HPV virus cause?
1. Cervical cancer
Cervical cancer is currently the only malignant tumor with a clear cause—carcinogenesis caused by persistent high-risk human papillomavirus (HPV) infection in the reproductive tract. 99% of cervical cancers are related to HPV infection.
The transmission channel of HPV is as “simple and clear” as its cause: sex is the most important way for it to spread. When the cervical tissues are infected with HPV virus, the virus will be latent in the cervix. Once the self-immunity declines, the virus will induce cancer of cervical cells.
2. Anal cancer
HPV virus can also be transmitted between the oral cavity (oral sex) and the reproductive organs. With the change of people’s concept of sex, the anus and genital area have become the key areas of infection. HPV16 and 18 cause nearly 90% of anal cancers.
The anus and the sex organs are less than one finger away, and they are in a special location, and they are kept in a humid and airtight environment for a long time. If the secretions are not cleaned in time, once the skin and mucous membranes are damaged, it is easy to cause infections such as fungi and bacteria, which is very conducive to the reproduction of HPV viruses.
3. Oropharyngeal cancer
In recent years, HPV is considered to be the fourth confirmed carcinogen of oropharyngeal cancer. In an article in the New England Journal of Medicine, it was pointed out that among the risk factors for oropharyngeal cancer, there is the possibility of HPV infection.
The article mentions a set of important data: HPV16-induced or HPV-related oropharyngeal cancer cases are increasing year by year. The proportion of HPV-positive oropharyngeal cancer in the United States has increased from 16.3% in the 1980s to 72.7% in the 2000s.
This data strongly confirms that oral contact can directly induce oropharyngeal cancer, and the HPV virus can be infected through oral contact, and the incubation period can be as long as 10-30 years.
After the picture is infected with HPV, will it definitely cause cervical cancer?
As of 2003, more than 200 types of HPV have been found, and as many as 30 types can infect the human body. According to the relationship between HPV and cervical cancer, it can be divided into low-risk type and high-risk type.
High-risk infections are very likely to cause high-grade precancerous lesions of cervical cancer, while low-risk infections will not cause cervical cancer.
The carcinogenic process of HPV does not happen overnight, and it does not necessarily lead to cervical cancer. Instead, it goes through several stages of HPV infection-persistent infection-precancerous lesions-cancer. The virus does not have obvious signs and symptoms in the early stage of infection.
In the case of uncertain type, the most important step is to perform a tissue biopsy. If it is a low-risk type, the virus can be eliminated by oral medication. High-risk type requires pathological diagnosis and considers surgery or radiotherapy and chemotherapy.
For the HPV virus, the most effective way at present is to vaccinate HPV-related vaccines. If conditions permit, it is recommended that both men and women vaccinate the vaccine to prevent the occurrence of the disease from the root cause.
