Cervical Cancer In India Should be Terminated By 2070

Human papillomavirus (HPV) screening and vaccination must be expanded in countries like India to prevent 15 million cervical cancer deaths among women by 2050, finds a Lancet research.

Countries like India must take up the screening and vaccination of Human papillomavirus (HPV) much seriously and on a higher scale to prevent 15 million cervical cancer deaths among women by 2070, reveals a Lancet research. Cervical cancer is the cancer of the cervix which doesn't show any typical symptoms at an early stage. Vaginal bleeding, pelvic pain, and pain during sexual intercourse are symptoms that occur during later stages.//

Causing the second-highest number of deaths among Indian women among cancer variants, cervical cancer, in a majority of cases, is caused by HPV, a group of more than 150 viruses.

Cervical Cancer - Types, Causes, Symptoms, Diagnosis, Treatment, Complications & Prevention
Cancer cervix refers to cancerous growth in the cervix and usually occurs in the transition called squamo-columnar junction.

‘Up to 84-90 percent of cervical cancers could be potentially prevented through screening and broad-spectrum HPV vaccinations.’

The efforts might even result in cervical cancer being eliminated as a public health hazard in India by 2070-79, according to the study, published in The Lancet Oncology journal.

Combining high uptake of the HPV vaccine and cervical screening could eliminate cervical cancer as a public health hazard in 149 out of 181 countries by 2100 and up to 13 million cases of cervical cancer by 2050.

If the high coverage of HPV vaccination and cervical screening cannot be achieved globally, over 44 million women could be diagnosed with cervical cancer in the next 50 years with two-thirds of these cases and an additional estimated 15 million deaths, would occur in countries with low and medium levels of development.

Pap smear and Cervical Cancer Screening
Pap smear is the most common test used in screening cervical cancer caused by an infection with human papilloma virus. Pap smear should be repeated every 1 to 3 years till the age of 65 years.

"More than two thirds of cases prevented would be in countries with low and medium levels of human development like India, Nigeria, and Malawi, where there has so far been limited access to HPV vaccination or cervical screening," said lead author Professor Karen Canfell from the Cancer Council New South Wales in Australia.

However, large disparities exist in cervical screening and HPV vaccination coverage among countries.

Human Papillomavirus Infection - Risk Factors, Symptoms, Screening, Treatment & Prevention
Human papillomavirus (HPV) infection, depending on the human papillomavirus that causes it, can result in common warts or can cause cervical cancer.

However, Canfell says that despite the enormity of the problem, their findings suggest that "global elimination is within reach with tools that are already available, provided that both high coverage of HPV vaccination and cervical screening can be achieved.

Cervical cancer is the fourth-most common cancer among women, with an estimated 570,000 new cases diagnosed worldwide in 2018, of which around 85 per cent occur in less developed nations.

Screening and broad-spectrum HPV vaccines could potentially prevent up to 84-90 per cent of cervical cancers, the study said.

"Diagnostic tests such as the pap smear are effective in identifying cancerous tendencies.

"However, these tests are available with a limited number of providers and largely within the cities. This makes screening sporadic and leaves out women who live in rural areas," Aneja added.
