In the United States, the cases of anal cancer and death are increasing dramatically, especially among older people and young black men, according to a new study. Researchers have explored trends in anal cancer cases over about 15 years, and have identified about 69,000 cases of anal cancer and 12,000 death cases caused by anal cancer. From 2001 to 2015, the cases of the most familiar type of anal cancer have grown by 2.7% every year, while death cases caused by anal cancer have increased by 3.1% per year from 2001 to 2016. In the National Cancer Institute’s journal, this study was published. Doctor Virginia Shaffer, who is the colorectal surgeon and associate professor at Emory University’s Winship Cancer Institute, has said that this study provides numbers to a trend that seems to be happening over the last decade. The lead author of this study, Ashish A. Deshmukh, has said that the finding of the startling rise in occurrence among the black millennials and white women is rising.
Following the US centers for disease control and prevention, more than 90% of the cases of anal cancers are connected with HPV. Anal cancer arrives at the end of the digestive tract. It is different from rectal or colon cancer, and it is most similar to the characteristics of cervical cancer. The most prevalent subtype of anal cancer is squamous cell carcinoma that is caused by the human papillomavirus, also known as HPV. Screening of anal cancer accomplished for some high-risk groups, but the study authors disputed their findings and suggested broader screening efforts should be considered.
The study has found that cases of anal cancer have increased in people aged 50 and over. It is because HPV vaccine guidelines are very narrow and limiting protection for older people. In 2006, when the HPV vaccine was first introduced, it was allowed for people within the age group of 9 to 26, so there was a large number of people who missed the vaccine. The study also has discovered the amount of advanced-stage cases is increasing, and this is because the treatment for HIV has improved.
