The hidden barrier to diagnosis: why vulvar cancer often waits months to be seen

Health · Published 20 October 2026 Swipe more like this →

In short: Vulvar cancer is a rare malignancy that often hides behind persistent itching or minor skin changes. Because of the sensitive nature of the area, many people delay seeking help. This delay can be significant, often spanning nearly a year before a formal diagnosis is ever made.

Vulvar cancer typically develops when DNA changes in the skin cells of the vulva—the area surrounding the urethra and vagina—cause them to multiply uncontrollably. While it can occur at any age, the average age of diagnosis is 65. In the UK, for instance, more than 40% of new cases occur in women aged 75 and older. The most common form is vulvar squamous cell carcinoma, which is frequently linked to the human papillomavirus (HPV), a common virus passed through sexual contact.

The progression of this cancer is often gradual. It may begin as vulvar intraepithelial neoplasia (VIN), a precancerous condition where abnormal cells develop on the surface of the skin. While many instances of VIN never progress to invasive cancer, a small number do. Other significant risk factors include tobacco use, a weakened immune system (such as from HIV or organ transplant medications), and chronic inflammatory conditions like lichen sclerosus, which causes the vulvar skin to become thin and itchy.

A major hurdle in treatment is the 'recognition uncertainty' experienced by patients. Because it is difficult to interpret whether bodily changes are normal or abnormal, patients often face a diagnostic delay of 6 to 11 months. This delay is frequently exacerbated by the stigma and taboo surrounding the anatomy. Early detection is critical; the sooner the cancer is identified, the less likely extensive surgery—which can sometimes require removing the entire vulva—will be necessary. Treatment typically involves a combination of surgery, radiation, and chemotherapy.
