A friend of mine once came back from a gynecology check-up and spent several days worrying after being told that "the cervical cytology test showed some abnormalities." Fortunately, after additional tests, it turned out to be nothing serious, but during those few days of fretting alongside her, one thought stayed with me. Cervical cancer is actually a cancer for which we have quite a long window to act. It is not a disease that appears suddenly and leaves no room to respond; on the contrary, it usually takes anywhere from a few years to more than a decade for a normal cell to turn into cancer. If you set up two nets during that long stretch of time — the vaccine and screening — you can filter out most of what could go wrong.
The cause of cervical cancer is fairly well defined. In most cases, a common virus called HPV, the human papillomavirus, lingers for a long time and gradually alters the cells. The virus itself is so common that almost anyone who has become sexually active will encounter it at least once, and most people's bodies clear it on their own. The problem arises when certain high-risk types do not leave and instead settle in. That is why the vaccine matters. It is most effective when given before exposure to the virus — that is, in adolescence, before becoming sexually active. In Korea, free vaccination is provided to girls around the age of 12. But many people think, "I'm already older, isn't it too late?" In fact, adult women also gain benefit from vaccination. It may not block every high-risk type, but it is far better than not being vaccinated at all. These days, vaccinating boys is increasingly recommended as well, since it not only helps prevent related cancers in them but also reduces the chance of passing the virus to a partner.
Being vaccinated does not mean you can skip screening. Surprisingly many people misunderstand this point. The vaccine blocks a few dangerous types; it does not shut out 100 percent of all cases. So you need to keep up with both — the vaccine as the vaccine, and screening as screening. Honestly, the cervical cytology test itself takes only a few minutes. Once you actually go through it, it is over so quickly that you wonder, "Did I really put this off for this?" The country also supports free screening once every two years for women aged 20 and older, so setting a reminder around your birthday is one good approach.
So what should you be careful about in everyday life? Nothing grand. Keep to the screening schedule, get the vaccine at the recommended time, and quit smoking. It is fairly well known that smoking raises the risk of cervical cancer, but this fact seems to be talked about less. It is also important not to brush off signals that are out of the ordinary — such as abnormal bleeding, unusual discharge, or bleeding after intercourse — with a casual "it's probably nothing." Of course, these symptoms do not always mean cancer at all, but when your body sends a signal, it is more reassuring to have it checked.
To sum up: cervical cancer is an uncommon kind of cancer in that its cause is relatively clear, there is a vaccine to block that cause, and there is screening to catch changes early — all three pillars of prevention are in place. Rather than turning away because it is frightening, it is far more helpful to pause and recall whether you have had your screening this year. If you haven't, try booking an appointment at a nearby gynecology clinic this week.
