Cervical cancer and papillomavirus


Each year in the world, 500,000 new cases (80% in developing countries), and 250,000 to 300,000 deaths

Each year in France, 3,000 new cases of cancer with about 1,000 deaths

To date, scientists have identified around twenty human papillomaviruses (HPVs) that cause cervical cancer – the first type of cancer to be recognized by WHO as being exclusively attributable to a viral infection. But the most common types are HPV 16 (responsible for 55% of cases) and HPV 18 (responsible for 12% of cases). These cancer-causing HPVs can also affect other mucous membranes and lead to anal or oropharyngeal cancer.


Human papillomaviruses or HPVs infect the epithelial cells in the skin or mucous membranes and are transmitted when these cells spread through a process known as desquamation. While some HPVs are low risk, causing benign lesions, other high-risk HPVs may lead to cancer. The HPVs that affect genital mucosa are sexually transmitted and occur frequently, from the very beginning of sexual activity – they are found in a third of women between adolescence and their early twenties. Although infections caused by HPVs can occur throughout adulthood in sexually active women, they often give rise to no symptoms and clear up on their own. But in 3 to 10% of infected women the infection is persistent, and some of these will go on to develop precancerous lesions known as cervical intraepithelial neoplasia, a precursor to cervical cancer. Several years may go by between initial infection with a cancer-causing HPV and the emergence of cancer.

A few figures

At global level, cervical cancer is responsible for approximately 250,000 to 300,000 deaths and 500,000 new cases each year (80% in developing countries), according to the International Agency for Research on Cancer. In Europe, nearly 65,000 women are affected, and approximately 25,000 new cases are reported annually, with a death rate of 4.7%. In France, there are 3,000 cases and more than 1,000 deaths each year, and around 30,000 women receive a diagnosis of high-grade cervical neoplasia or cancer each year.

Cervical cancer is the second most common form of cancer in women, and the number of new cases was estimated at 445,000 in 2012.

In 2012, some 270,000 women died from cervical cancer, with more than 85% of deaths occurring in low and middle-income countries.


Precancerous lesions are generally treated by surgery (cone biopsy or conization). Cervical cancer is treated by a combination of surgery and radiotherapy with adjuvant chemotherapy, which is effective in early stages. Therapeutic vaccines for the treatment of precancerous lesions and cervical cancer caused by HPV 16 and/or HPV 18 are currently in clinical trials.


Cervical cancer prevention currently involves methods to prevent sexually transmitted infections (condoms, screening for sexual partners) and especially routine cervical screening in women.

A prophylactic vaccine that protects against infection with HPV 16 and 18 – thereby preventing two thirds of cervical cancers – is currently available. This vaccine has no therapeutic benefits and does not protect women who have already been infected. The opinion delivered on September 28, 2012 by the French High Council for Public Health (HCSP) states that vaccination is recommended for girls aged between 11 and 14 and that every opportunity should be taken to encourage administration of the vaccine. The HCSP also recommends that catch-up vaccination should be limited to women aged 20 or under, since the vaccine is most effective if administered before exposure to the risk of HPV infection.
