Vaccination and screening of generalizations can quickly eliminate cervical cancer into high-income countries almost forty years, and in most countries by the end of the century, according to a study published in the magazine The Lancet Oncology .

If implemented by 2020, these measures could increase the prevalence of cervical cancer under four cases per 100,000 women in most countries, according to this work.

"This is the potential threshold below that cervical cancer could be considered to be erased as a public health problem," said the study's authors, according to which 13.5 million cases could be avoided over the next 50 years.

In the early February, the World Health Organization (WHO) said the diagnosis of 570,000 new cases of cervical cancer was globally in 2018. Around 310,000 women die every year, mainly in the world. low to medium, making it the fourth most common cancer in women.

"Despite the size of the problem, our work seems to show that the abolition of the disease globally is possible with the available equipment, provided that vaccination and screening provision increase ", said senior author of study, Australian researcher Karen Canfell.

At the forefront of recommended preventive measures there is a vaccine against HPV, a group of viruses that are transmitted through sexual intercourse. Two of them, HPV 16 and 18, cause up to 70% of cervical cancer and cancers before cancer, according to WHO, which recommends vaccination of women aged 9 to 14.

The published study is based on the assumption that more than 80% of girls aged 12 to 15 are vaccinated by 2020 and 70% of women are screened twice in their lives. In this case, and according to statistical projections, the cervical cancer rate would be below four cases per 100,000 women by 2059 for countries with very high levels of development (such as the United States). United or France).

2069 would cross this bar for high-developed countries (such as Brazil or China), by 2079 for medium-developed countries (India or Vietnam) and by 2100 for countries with low development levels (Ethiopia or Haiti). On the other hand, the interesting bar could not be crossed before the end of the century in a handful of countries, including Kenya or Uganda.
