Cervical cancer symptoms, screening and prevention: a clear, kind guide

The short answer

The main cervical cancer symptoms are unusual vaginal bleeding, unusual discharge, and pain during sex or in the lower tummy. Early cervical cancer often causes no symptoms at all, which is why screening matters. Most people with these symptoms do not have cancer, but a lasting change is worth checking with your GP.

In short

• Main symptoms: unusual bleeding (between periods, after sex, or after menopause), unusual discharge, and pelvic pain.
• Early cervical cancer often causes no symptoms, so cervical screening is the single most important check.
• Nearly all cervical cancers are caused by a common virus called HPV, which the HPV vaccine protects against.
• Cervical cancer is one of the most preventable cancers, through vaccination and screening together.
• General information, not medical advice. Show your GP any unusual or lasting bleeding.

Cervical cancer is one of the few cancer types we can very nearly prevent. A vaccine and a simple test together stop the large majority of cases, which is a genuinely hopeful thing. This guide explains the symptoms, the screening, and the vaccine, in plain language.

What are the symptoms of cervical cancer?

Signs worth noticing include:

• Bleeding between periods, after sex, or after the menopause
• Heavier periods than usual, or bleeding that is new for you
• A change in vaginal discharge, especially if it is unpleasant
• Pain or discomfort during sex
• Pain in your lower tummy, pelvis or back

These symptoms are usually caused by something other than cancer, such as an infection. That does not mean you should wait them out. If bleeding is unusual for you, or a symptom will not settle, please see your GP, even if it feels awkward to raise.

What is cervical cancer, and what causes it?

Most HPV infections clear on their own and never cause harm. In a small number of people the virus lingers and slowly changes cervical cells, which can, over years, develop into cancer if not found. Because that process is slow, screening usually catches the changes long before they become cancer, sometimes years earlier.

What is cervical screening, and how does the smear test work?

Everyone registered with a GP as female is invited from age 25 to 64:

• Aged 25 to 49, if no HPV is found you are invited every five years (in England this changed from every three years in July 2025, after evidence showed five-yearly screening is just as safe)
• Aged 50 to 64, if no HPV is found you are invited every five years
• If HPV is found, you are invited more often, or for a closer look called a colposcopy

The test itself takes a few minutes, and while it is not most people's favourite appointment, it is quick and the nurse will help you feel at ease. Attending when you are invited is one of the simplest and most powerful things you can do for your health.

What is the HPV vaccine, and does it prevent cervical cancer?

The vaccine is one half of a powerful pair. On its own it prevents most cervical cancers, and combined with screening it prevents the great majority.

It also protects against some other cancers linked to HPV. If you or your child were offered the vaccine and missed it, it is worth asking your GP whether a catch-up is possible.

When should I see my GP about cervical symptoms?

Most people with these symptoms do not have cancer, and getting checked simply settles the question. If something does need treatment, whether it is an infection or a cell change, finding it early almost always makes it simpler. And if you are overdue a screening test, this is a good moment to book one.

How is cervical cancer diagnosed?

• Cervical screening, checking for HPV and cell changes
• Colposcopy, a closer look at the cervix using a magnifier
• A biopsy, taking a small sample to examine
• Scans such as MRI or CT, to check the size of a cancer and whether it has spread

Many changes found this way are pre-cancerous rather than cancer, and treating them at that stage prevents cancer from ever developing. That is the quiet power of screening.

What are the treatments for cervical cancer?

• Removing abnormal cells (a procedure called LLETZ) treats pre-cancerous changes and prevents cancer forming.
• Surgery removes the cancer, and for some early cancers can preserve fertility.
• Radiotherapy with chemotherapy is a common treatment for cancer that has grown beyond the earliest stage.
• Chemotherapy, targeted therapy and immunotherapy are used for advanced cervical cancer.

Some treatments can affect fertility, so if having children matters to you, tell your team early, as there are often options to protect it. Support is available throughout, from your team and charities such as The Eve Appeal and Macmillan, and our prevention guides share more.

What do the stages of cervical cancer mean?

Whatever the stage, your team can explain what it means for you specifically, which matters far more than the number itself. Many cervical cancers are found early, when treatment is most effective.

Can cervical cancer be prevented?

Steps that make the biggest difference:

• Take up the HPV vaccine if you or your child are offered it.
• Attend cervical screening every time you are invited.
• See your GP promptly about unusual bleeding, discharge or pelvic pain.
• Stop smoking, which raises the risk of cervical cancer, with free NHS support if you would like it.

No step removes all risk, and no one who develops cervical cancer is to blame. But vaccination and screening move the odds dramatically, which is the whole idea behind our mission. If you want help finding trusted support, you can contact us any time.
