Cervical cancer develops quietly. In most cases, it takes between 10 and 20 years from the first abnormal changes in cervical cells for the disease to become invasive cancer.

Those early changes are almost always caused by certain high-risk strains of human papillomavirus (HPV), a very common virus passed through skin-to-skin contact during intimate moments.

What makes cervical cancer particularly dangerous is not how fast it spreads, but how silently it begins. In its early stages, it rarely causes pain, bleeding or any obvious warning signs.

Many women feel completely healthy while abnormal cells slowly develop. That silence is precisely why regular screening is so important. A simple test can detect problems years before they turn life-threatening.

How screening works and why it matters

Two main screening approaches are used today. The older method, the Pap smear, examines cells collected from the cervix under a microscope to identify abnormal changes. The newer and more accurate method tests directly for high-risk HPV types that are known to cause cervical cancer.

Many health systems now prefer HPV testing because it detects risk earlier and produces fewer unclear results. By identifying the virus before it causes visible cell damage, doctors can monitor or treat women long before cancer develops.

When screening finds abnormal cells or high-risk HPV, the next steps are usually straightforward. Treatment options include thermal ablation, which uses heat to destroy abnormal tissue, cryotherapy, which freezes it, or a procedure known as LEEP that removes affected tissue using a small wire loop.

These procedures often take only minutes, are done under local anaesthetic and have very high success rates in stopping cancer before it starts.

The life-saving impact of early detection

The impact of consistent screening is already clear in countries where organised programmes reach most women. Death rates from cervical cancer have fallen by between 50 and 80 per cent over the past few decades in places that introduced regular screening as early as the 1960s and 1970s.

When women are screened every few years, the likelihood of developing advanced cervical cancer drops dramatically, in some cases by more than 90 per cent. Early detection changes everything.

Five-year survival rates for cervical cancer diagnosed at an early, localised stage are typically above 90 per cent. Once the disease spreads to distant parts of the body, survival rates fall sharply.

According to the World Health Organisation (WHO), cervical cancer is one of the most preventable and treatable forms of cancer when detected early, with timely screening, HPV vaccination and appropriate treatment capable of stopping the disease before it becomes life-threatening.

“January is cervical cancer awareness month! Get informed, Get screened, Get vaccinated #CervicalCancer can be prevented & treated, if caught early,” WHO X post.

Screening keeps the disease in its earliest stages or prevents it altogether. It turns cervical cancer from a deadly diagnosis into a highly manageable condition.

Removing barriers to screening

Recent improvements have made screening easier and more accessible. Many health systems now offer HPV self-collection kits, allowing women to collect their own samples in private and submit them for testing. Studies show that these samples are just as reliable as those collected in clinics.

This option has already increased participation in several countries, particularly among women who previously avoided screening due to fear, stigma or lack of time. It demonstrates how small system changes can have a major public health impact.

In most high-resource settings, current guidelines recommend starting screening between the ages of 25 and 30, then repeating every five years using a primary HPV test, or every three years where Pap smears are still used. The longer interval reflects better understanding of how slowly cervical cancer develops and the higher sensitivity of HPV testing.

HPV vaccination provides another strong layer of protection, especially when given before exposure to the virus. However, screening remains essential even for vaccinated women, as vaccines do not cover every high-risk HPV type and many women were vaccinated later in life or not at all.

The message for Cervical Cancer Awareness Month is simple and supported by decades of evidence. Regular screening remains one of the most effective ways to prevent death from a cancer that is almost entirely avoidable. A short test every few years can interrupt a process that might otherwise continue unnoticed for years.

Taking that small step, whether by booking an appointment or using a self-collection kit when available, remains one of the clearest actions a woman can take to protect her own life.
