Anal cancers and HPV: 90% of anal cancers are related to HPV
Anal cancers and HPV: 90% of anal cancers are related to HPV. HPV vaccine is the the solution of prevention for both males and females
In 2018, Marcia Cross, the actor of Bree in the American TV series “Desperate Housewives”, blew herself up with anal cancer on the show. In many people’s minds, anal cancer is often regarded as because of the special part of the disease. A very shameful cancer.
And the reason why Cross boldly announced the news of his cancer is to tell those patients who suffer from anal cancer like her not to be too ashamed of the cancer, because the patient has suffered too much for the cancer, and he has done nothing wrong. what.
In fact, before Cross was diagnosed with anal cancer, her husband had found throat cancer, and their cancer came from the same murderer-HPV.
HPV-the culprit behind anal cancer
HPV, the culprit of anal cancer, is also called human papillomavirus. There are more than 100 subtypes. Among them, it can be divided into high-risk type and low-risk type according to the degree of risk. There are more than a dozen subtypes that can cause cancer, of which two are “widely known”. Species-HPV16 and HPV18 are the most common types. The transmission route of HPV is mainly through sexual contact, and if it comes into contact with the skin of a patient carrying the HPV virus, there may also be a risk of infection. About 99% of cervical cancer, 95% of anal cancer, and 70% of mouth cancers are It is related to the HPV virus.
However, it should be noted that it is not that you will get cancer if you are infected with the HPV virus. Generally speaking, the risk of cancer is only if the infection is more than two years and the infection continues. Under normal circumstances, after being infected with the HPV virus, 80 to 90% of people can be infected within a few months to a year and a half. It is automatically cleared in the time.
Therefore, don’t be too afraid of the HPV virus. Even if you are infected, just keep paying attention. However, for anal cancer, it is still necessary to “snack”.
“Anal sex” easily provokes anal cancer
The anus and sex organs are close, so the anus is very easy to be infected with HPV virus. In addition, because the anus is moist and secreted, the skin and mucous membranes are thin and easy to be damaged, which can easily cause fungal and bacterial infections, which is very conducive to the reproduction of HPV virus.
The American Cancer Center’s survey results show that anal sex can increase the risk of anal cancer. In the United States, 40% of men aged 25 to 44 have had anal sex, and about 30% of women have had anal sex. People who have anal sex have a higher risk of anal cancer than others.
Dr. Greco of Chase Cancer Center said that about 90% of anal cancers are caused by HPV infection. People with anal sex, smoking, genital diseases, and many sexual partners may become “victims” of anal cancer. .
Due to the secret location of the anus, it is easy to be ignored when cancer comes. So, what symptoms will the body show when anal cancer appears?
Anal cancer occurs, the body will have 4 symptoms
When two or more of the following symptoms appear, you should go to the hospital to check the health of the anus:
1. Bleeding, foreign body sensation, increased secretion
Hematochezia is one of the most common symptoms of anal cancer in the early stage, especially for people with hemorrhoids, it is easy to be misdiagnosed. After the hemorrhoids are ruled out, anal bleeding, foreign body sensation, and excessive discharge should be careful of anal cancer.
2. Pain, itching
Due to the impact of tumors, patients with anal cancer will experience symptoms of anal itching and pain.
3. Abnormal stool
When anal cancer has progressed to a certain level, the patient will have thinner stools.
4. Swollen lymph nodes
Patients with anal cancer will also find swollen lymph nodes in the pelvis or groin at a later stage.
The above are the common symptoms of anal cancer, and the key to preventing anal cancer is to prevent HPV infection!
To prevent anal cancer, both men and women must be vaccinated against HPV
Many people think that only women can be vaccinated against HPV. In fact, it is not true. Both men and women, even men who are gay or bisexual, can be vaccinated against HPV to reduce the risk of anal cancer.
Researchers from Monash University in Australia published a study in the newspaper “The Lancet Infectious Diseases” showing that the HPV infection rate has dropped significantly after being vaccinated with HPV vaccine.
The research team conducted a survey between 200 gay and bisexual men who were vaccinated with HPV vaccine and 200 men who were not vaccinated with HPV, and found that after vaccination, the proportion of HPV infection in the anus was only 7%. The infection rate of vaccinators is 28%. It can be seen that HPV vaccination can reduce the risk of men contracting the HPV virus, so it should be vaccinated as much as possible.
In fact, the HPV virus is currently one of the few viruses that can be prevented by vaccines. Therefore, if conditions permit, HPV vaccines should be vaccinated as soon as possible.
