Vulval cancer risk

Preventable cases

Vulval cancer cases are preventable, UK, 2015

 

Caused by infections

Vulval cancer cases caused by infections, UK, 2015

The estimated lifetime risk of being diagnosed with vulval cancer is 1 in 230 (less than 1%) for females born in 1961 in the UK.[1]

These figures take account of the possibility that someone can have more than one diagnosis of vulval cancer in their lifetime ('Adjusted for Multiple Primaries' (AMP) method).[2]

    About this data

    Data is for UK, past and projected cancer incidence and mortality and all-cause mortality rates for those born in 1961, ICD-10 C00-C14, C30-C32.

    Calculated by the Cancer Intelligence Team at Cancer Research UK, 2023 (as yet unpublished). Lifetime risk of being diagnosed with cancer for people in the UK born in 1961. Based on method from Ahmad et al. 2015, using projected cancer incidence (using data up to 2018) calculated by the Cancer Intelligence Team at Cancer Research UK and projected all-cause mortality (using data up to 2020, with adjustment for COVID impact) calculated by Office for National Statistics. Differences from previous analyses are attributable mainly to slowing pace of improvement in life expectancy, and also to slowing/stabilising increases in cancer incidence.

    Last reviewed:

    69% of vulval cancer cases in the UK are preventable.[1]

    Vulval cancer risk is associated with a number of risk factors.[2,3]

    Vulval Cancer Risk Factors

      Increases risk Decreases risk
    'Sufficient' or 'convincing' evidence
    • Human papillomavirus (HPV) type 16
     
    'Limited' or 'probable' evidence
    • Human immunodeficiency virus (HIV) type 1
    • HPV types 18, 33
     

    International Agency for Research on Cancer (IARC) classification. World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) classification does not include vulval cancer because it is not generally recognised to have a relationship to food, nutrition, and physical activity.

    69% of vulval cancer cases in the UK are caused by HPV infection.[2]

    5% of vulval cancer cases in Europe are HPV-positive, a meta-analysis showed.[3] 81% of vulval intraepithelial neoplasia (VIN) cases in Europe are HPV-positive.[2] HPV type 16 is the most common type in vulval cancer cases worldwide (32%), followed by HPV types 33 (5%) and 18 (4%).[3] Vulval cancer cases are more likely to be HPV-positive in younger women.[3]

    Vulval cancer risk is higher in women with genital warts, versus women without, a cohort study showed.[4] This is probably due to co-infection with high-risk HPV types (genital warts are caused by low-risk HPV types).[4]

    Vulval/vaginal cancer risk is 6.5 times higher in people with HIV/AIDS compared with the general population, a meta-analysis showed.[2] This is probably due to co-infection with, and reduced capacity to clear, Human papillomavirus (HPV).[2,3]

    Vulval/vaginal cancer risk among people with HIV does not vary by level of immunosuppression, a cohort study showed.[4] Vulval/vaginal cancer risk among people with HIV has increased over time (probably related to changing HPV prevalence), a cohort study showed.[5]
