Cervical cancer - are today’s young women at greater risk?
The trend towards ever-earlier first sexual experience is putting young women at a higher risk of cervicalRelating either to the cervix (the neck of the womb) or to the cervical vertebrae in the neck (cervical spine). cancerAbnormal, uncontrolled cell division resulting in a malignant tumour that may invade surrounding tissues or spread to distant parts of the body., says immunologist and cervical cancer expert, Professor Margaret Stanley of the University of Cambridge.
In an article in the April 2009 issue of the Journal of Family Planning and Reproductive Health Care, Professor Stanley explains that in teenagers the tissues of the cervixAny neck-like structure; most commonly refers to the neck of the uterus. are still developing and are especially vulnerable to attack by the human papillomavirus (HPVAn abbreviation for human papilloma virus, a sexually transmitted virus that can cause genital warts and may also have a role in the development of various cancers.), which is known to be the main cause of cervical cancer. The virus, which is caught through sex, is very common, but can only cause harm if the body’s natural defences do not get rid of it (rather like a cold).
“It seems that the immaturity of the cervix in teenage girls makes it easier for HPV get into the cells and stay there,” says Professor Stanley. “Although it can take around 10 to 20 years for cervical cancer to develop, the stage is already set. If girls start having sex around 14 or 15, which is now quite common in the UK, in the next few years will we see more young women with cervical cancer?”
Professor Stanley points out that the UK cervical screeningA way to identify people who may have a certain condition, among a group of people who may or may not seem to programme has been very successful in preventing cervical cancer. However, she is worried that the raising of the age at which women are called for their first smear in England, from 20 to 25 years, did not take into account more recent changes in sexual behaviour. “Were the studies able to allow for the lowering age at sexual debut which has been seen in the last 10 to 15 years? The effects of this greater risk may not become apparent for another few years yet. Until we are sure, I believe we should still be screening women under 25.”
