Older women have the highest risk of dying from cervical cancer

Denmark has one of highest incidences of cervical cancer in the Western world. But once a person has turned 65, they are no longer automatically screened—even though older women are, in fact, the cohort with the highest mortality. This is shown by new research from Aarhus University and Aarhus University Hospital.

“Cervical cancer has become known as a young women’s disease. But it’s a myth that it only affects young people. In fact, the mortality rate among women above the age of 65 is 25 to 30 percent higher than previously thought,” says medical doctor and postdoc Anne Hammer from the Department of Clinical Medicine, Aarhus University and Aarhus University Hospital.

She is behind the new study which has just been published in the scientific journal Acta Obstetricia et Gynecologica Scandinavia. The researchers looked at cervical cancer mortality rates in Denmark between 2002 and 2015 and found that the over-65s stood out. For example, the mortality rate was five times higher among woman aged 75 to 79 compared to those aged 40 to 45.

Advanced cancer

The research results support a study from November 2018 in which Anne Hammer and her research colleagues found that older women were very often diagnosed so late that the cancer was already too big to be surgically removed. In such cases, patients are instead treated with radiotherapy and chemotherapy, which are associated with side effects such as pain, and urination and defecation discomfort.

More than half of the older women with cervical cancer who had stopped screening due to age are diagnosed with cancer that is so advanced that surgery is no longer possible. “When people are screened, the cancer can be discovered in its initial stages or at such an early stage that surgical treatment is still possible. This significantly reduces the risk of dying,” says Anne Hammer.

Older women should also be screened

With the current rules, the screening programme stops if a person is tested negative between the ages of 60 to 64. According to Anne Hammer, there are plenty of grounds, especially with the new studies, to introduce initiatives to reduce the incidences and mortality from cervical cancer. This could for example be done by extending the screening programme.

“The negative test does not guarantee that someone won’t get the disease after the screening ends, because the HPV virus that is the cause of the cancer can lie dormant in the body,” says Anne Hammer. She also points out that there will very likely be fewer young women with cervical cancer in five to 10 years time due to the HPV vaccine.
