Vulvar cancer can be painful, but pain is not always the first symptom. The most common early sign is actually persistent itching, reported by 50 to 60 percent of patients as their initial symptom. Pain, burning, and tenderness often develop as the disease progresses, and the type of discomfort changes significantly between early and advanced stages.
Itching Often Comes Before Pain
Chronic itching (pruritus) is the symptom most likely to appear first. In a study of 76 women with vulvar cancer, nearly half reported chronic itching as the symptom that brought them in for evaluation, and the average time between that first symptom and a cancer diagnosis was about 13 months. This long gap matters because itching is easy to dismiss or attribute to a yeast infection, irritation, or skin condition.
Pain typically enters the picture later, sometimes alongside the itching and sometimes replacing it. Squamous cell carcinoma, the most common type of vulvar cancer, often presents as a persistent bump, raised patch, or ulcer with associated bleeding, itching, and pain that doesn’t respond to over-the-counter creams or anti-inflammatory treatments. When a sore or lesion on the vulva doesn’t heal after a few weeks, that’s a meaningful signal regardless of whether it hurts.
What the Pain Feels Like
The pain associated with vulvar cancer varies depending on the stage and location of the tumor. Common descriptions include burning, soreness, and a general tenderness across the vulva. Some women experience sharp or stinging sensations, while others describe a constant, dull ache. The cancer can also cause pelvic pain, particularly during urination or sexual intercourse. These functional symptoms, pain triggered by specific activities, can be among the most disruptive to daily life.
Some cases of vulvar cancer are entirely asymptomatic, especially in the earliest stages. A woman may notice a visible change, like a lump, thickened skin, or a color change on the vulva, without any accompanying discomfort. This is one reason why visual self-awareness matters: not all vulvar cancers announce themselves with pain.
How Pain Changes as the Cancer Advances
In early-stage vulvar cancer, discomfort tends to stay localized to the surface of the skin. As the cancer grows deeper into tissue, the nature of the pain shifts. Tissue damage from the tumor causes inflammation that sensitizes nearby nerves. If this continues over time, the nervous system itself begins to change, transitioning from ordinary pain signaling to a more complex form called neuropathic pain. This type of pain is harder to control and can persist even after the original source of irritation is treated.
Neuropathic pain involves structural and chemical changes in both the peripheral nerves (near the vulva) and the central nervous system. Once these changes take hold, they are very difficult to reverse. This is one of the reasons early detection matters so much: catching vulvar cancer before it infiltrates deeper tissue can prevent the kind of nerve involvement that leads to chronic, treatment-resistant pain.
Pain During and After Treatment
Treatment for vulvar cancer, whether surgery, radiation, or both, introduces its own pain challenges. Surgery is the most common approach, and most women experience moderate pain afterward. Studies using standardized quality-of-life scales found that pain scores after surgery ranged from 29 to 45 on a 0-to-100 scale, with higher numbers indicating more pain. One study found a statistically significant increase in pain from before surgery to three months after.
The extent of surgery directly affects recovery. Women who undergo removal of lymph nodes in the groin (a procedure done when cancer may have spread) tend to have longer-lasting pain. Many in this group reported ongoing lower-limb symptoms including pain, weakness, and stiffness of moderate to severe intensity throughout a two-year observation period. Research found that pain had a major impact on all women who had surgery, with many relying on painkillers for up to six months.
Radiation therapy can also cause vulvar pain, both during treatment and afterward. In some cases, radiation damages the pudendal nerve, which supplies sensation to the vulvar area, leading to chronic neuropathic pain that requires specialized management such as nerve blocks.
What a Biopsy Feels Like
If your doctor suspects vulvar cancer, the next step is a biopsy, a small tissue sample taken from the affected area. This is done in an office setting with local anesthesia. The injection of the numbing agent is typically the most uncomfortable part of the procedure. A topical numbing cream may be applied first to reduce the sting of the needle, and research suggests that a lidocaine-prilocaine cream applied before the biopsy can result in lower pain scores compared with a standard injection alone. The tissue removal itself, done with a small punch tool or scalpel, is brief, and a clotting agent is applied to stop any bleeding.
Symptoms Worth Paying Attention To
Because vulvar cancer can range from painless to severely uncomfortable depending on the stage, focusing on pain alone as a warning sign can be misleading. The combination of symptoms to watch for includes:
- Persistent itching or burning that doesn’t resolve with standard treatments
- A lump, sore, or ulcer on the vulva that doesn’t heal
- Skin changes such as thickening, color changes (lighter or darker patches), or a wart-like growth
- Bleeding not related to your menstrual cycle
- Pain during urination or sex that is new or worsening
Any of these symptoms lasting more than a few weeks warrants evaluation, whether or not pain is present. The 13-month average delay between first symptoms and diagnosis suggests that many women wait too long, often because the early signs mimic common, benign conditions. Pain that does develop tends to mean the cancer has progressed beyond its earliest, most treatable stage.
