Find the mystery about uterine cancer

A recent scientific discovery has found where and how uterine cancer arises in the human body, which has been considered a medical mystery for decades.

Doctors have found that the abnormal density of uterine cells in the womb of women infected with HPV (sexually transmitted virus) is the cause of most cases of cancer. uterine letter.

In the 1920s, doctors in Massachusetts (USA) discovered a related phenomenon. It is the women involved in the treatment of cervical burn, also known as the process of burning cells, after childbirth, almost never get uterine cancer, but they cannot explain it at star.

Now, doctors believe that the process of cervical burning has helped to destroy host cells that are not able to regenerate. Host cells are the type of living cells that viruses use as a place to multiply.

Doctors have found out where and how the uterine cancer arises on the human body

This discovery prompted health professionals to consider restoring the use of the process to help prevent the spread of this dangerous disease in poor countries. Every year, nearly 530,000 women are diagnosed with uterine cancer worldwide and 275,000 people die from the disease, according to the World Health Organization (WHO).

The rate of women suffering from this disease in the US and some Western countries is extremely low.Cervical smear (Pap smear) and routine testing in these countries, which were popular in the 1950s, helped reduce the incidence of death from uterine cancer by 65% ​​in four decades. Next year, according to the WHO report.

Dr. Christopher Crum, who is currently working on the above-mentioned research topic with colleagues at Harvard University Medical School (USA) and the Science and Technology Research Organization in Singapore, has found the place of cancer. uterus arises.

He discovered that the cells that the cancer arises are often located near the cervical head, at the intersection of the vagina and the uterus - which is called the squamo-columnar junction.

Scientists hope that further research will find similar cells that are linked to other cancers as well as caused by HPV viruses, such as anal and throat cancer.

Dr Crum said the findings could be beneficial for countries in South Asia and Africa, where women are less likely to receive routine screening or vaccination against uterine cancer.
