Researchers have examined trends in anal cancer cases for about 15 years, during which time they have identified approximately 69,000 cases of anal cancer and more than 12,000 deaths.
Our findings regarding the increase in the incidence of black women and white women, the increase in distant disease rates and the increase in anal cancer mortality rates are very important. UTHealth Public Health School said in a statement. "Given the historical perception that anal cancer is rare, it is often neglected."
Distant stage disease is when cancer spreads to other parts of the body.
From 2001 to 2015, the most common anal cancer cases increased by 2.7% per year, while anal cancer mortality rates increased by 3.1% per year from 2001 to 2016.
"There is a trend that seems to have taken place in the last decade," the study published in the National Cancer Institute Journal. Said. “In this sense, he gives us what we expect.” Shaffer was not involved.
Anal cancer occurs where the digestive system ends. It is different from colon or rectal cancer and most similar to cervical cancer.
The most common subtype of anal cancer is squamous cell carcinoma caused by human papilloma virus known as HPV.
Who was affected by anal cancer?
The study found that anal cancer cases increased significantly in people 50 years and older.
Anal cancer rates are also increasing among young black males.
The study also found that the number of advanced stage cases was increasing. This may be partly due to the improved HIV treatment, Shaffer said, meaning that patients live safely with the immune system for longer periods of time and make further progress when they are diagnosed with cancer.
There's still stigma around the anal cancer.
"I know there are people who are ashamed," Cross said in June, "CBS This Morning." “You have cancer. Then you want to feel it? "You're ashamed that you did something bad because it resided in your anus."
Anal cancer has become “quite taboo, Sh Shaffer said, orum I think historically it is due to some known risk factors.
Insanlar If people are experiencing symptoms, they should see a doctor because I think a lot of people & # 39; Oh, it's just hemorrhoids. he thinks and doesn't take control of something, which means you won't recognize him very, very much. "
To strengthen forward-looking prevention efforts, Shaffer said that all people who qualify for vaccination should do so, and that existing vaccine guidelines should be worked to determine if they can be extended to other patients.
