Vaginal cancer is a rare type of cancer that begins in the vaginal tissues. While it accounts for only about 1-2% of gynecological cancers, early detection is crucial for successful treatment outcomes. Understanding the warning signs and symptoms can help you seek timely medical care and improve your prognosis.
Many women with early-stage vaginal cancer may not experience any symptoms at all, which is why regular gynecological examinations are essential. However, as the cancer progresses, various symptoms may appear. Being aware of these signs can make a significant difference in catching the disease early.
In this comprehensive guide, we’ll explore the most common symptoms of vaginal cancer, their causes, prevention strategies, and answer frequently asked questions to help you better understand this condition.
1. Abnormal Vaginal Bleeding
Abnormal vaginal bleeding is the most common symptom of vaginal cancer, occurring in approximately 80% of diagnosed cases. This symptom can manifest in several ways and should never be ignored, especially if you’ve already gone through menopause.
What to watch for:
- Bleeding between menstrual periods
- Bleeding after menopause
- Bleeding after sexual intercourse
- Heavier or longer menstrual periods than usual
- Spotting or light bleeding at unexpected times
The bleeding occurs because cancerous tumors can erode blood vessels in the vaginal wall, causing them to break and bleed. In postmenopausal women, any vaginal bleeding is considered abnormal and warrants immediate medical evaluation. Even light spotting should be discussed with your healthcare provider, as early-stage vaginal cancer can sometimes present with minimal bleeding.
2. Unusual Vaginal Discharge
Abnormal vaginal discharge is another significant warning sign of vaginal cancer. Unlike normal discharge, which is typically clear or whitish and odorless, discharge associated with vaginal cancer has distinctive characteristics that set it apart.
Characteristics of concerning discharge:
- Watery discharge that may be excessive
- Foul-smelling or malodorous discharge
- Blood-tinged or pinkish discharge
- Discharge with an unusual color (brown, gray, or greenish)
- Persistent discharge that doesn’t respond to typical treatments
The discharge may be caused by the tumor breaking down tissue or by infection secondary to the cancer. The amount can vary from light spotting on underwear to requiring the use of sanitary pads. If you notice any persistent changes in your vaginal discharge, particularly if accompanied by other symptoms, consult your doctor for proper evaluation.
3. Pelvic or Vaginal Pain
Pain in the pelvic region or vagina is a common symptom that often appears as vaginal cancer advances. This pain can range from mild discomfort to severe, debilitating pain depending on the cancer’s size, location, and stage.
Types of pain you might experience:
- Dull, aching pain in the pelvis
- Sharp or stabbing pains in the vaginal area
- Pain during sexual intercourse (dyspareunia)
- Persistent pain that doesn’t go away with over-the-counter pain relievers
- Pain that worsens over time
- Pain that radiates to the lower back or legs
The pain occurs when the tumor grows and puts pressure on surrounding tissues, nerves, and organs. As the cancer invades deeper tissues, the pain typically becomes more intense and constant. Pain during intercourse is particularly common and may be one of the first symptoms women notice.
4. A Lump or Mass in the Vagina
Some women may feel a lump or mass in the vagina, either during self-examination or by chance. This is often one of the more obvious physical signs of vaginal cancer, though it typically appears in more advanced stages of the disease.
The lump may have the following characteristics:
- Feel firm or hard to the touch
- Be painless initially but may become tender as it grows
- Vary in size from small (pea-sized) to larger masses
- Be located anywhere along the vaginal wall
- Cause a sensation of fullness or pressure in the vagina
Not all vaginal lumps are cancerous—many are benign cysts or other non-threatening growths. However, any new lump or mass discovered in the vagina should be examined by a healthcare professional promptly. Your doctor may perform a biopsy to determine whether the growth is benign or malignant.
5. Painful or Difficult Urination
Urinary symptoms can develop when vaginal cancer grows large enough to press against the bladder or urethra, or when it spreads to these nearby structures. These symptoms can significantly impact your quality of life and should prompt medical evaluation.
Urinary symptoms to watch for:
- Pain or burning sensation during urination (dysuria)
- Increased frequency of urination
- Urgent need to urinate
- Difficulty starting or maintaining urine flow
- Feeling that the bladder isn’t completely empty after urination
- Blood in the urine (hematuria)
These symptoms occur because the tumor can obstruct the urinary tract or invade the bladder wall. While urinary symptoms are common with many conditions, including urinary tract infections, their persistence despite treatment or occurrence alongside other vaginal cancer symptoms requires thorough investigation.
6. Constipation or Bowel Changes
When vaginal cancer spreads or grows toward the back wall of the vagina, it can affect the rectum and bowel function. These symptoms typically indicate more advanced disease but are important to recognize.
Bowel-related symptoms include:
- Persistent constipation that doesn’t improve with dietary changes or laxatives
- Pain during bowel movements
- Feeling of incomplete evacuation
- Blood in the stool
- Changes in stool shape or caliber
- Rectal pain or pressure
These symptoms develop when the tumor grows large enough to press against the rectum or when cancer cells invade the rectal wall. The proximity of the vagina to the rectum means that advanced vaginal cancers can affect bowel function. While these symptoms can be caused by many gastrointestinal conditions, their combination with other vaginal cancer symptoms warrants immediate medical attention.
7. Pelvic Swelling or Leg Swelling
Swelling in the pelvic area or legs is typically a sign of advanced vaginal cancer and occurs when the disease has spread to lymph nodes or blocked lymphatic drainage.
What you might notice:
- Swelling in one or both legs (lymphedema)
- Swelling in the pelvic or groin area
- Heaviness or aching in the legs
- Skin that appears stretched or shiny
- Difficulty fitting into shoes or clothing
- Reduced flexibility in affected joints
This swelling occurs when cancer blocks the lymphatic vessels that normally drain fluid from the legs and pelvic region. The blockage causes fluid to accumulate in the tissues, leading to edema. Lymph node involvement also indicates that cancer may have spread beyond the vagina, which affects treatment planning and prognosis. Any unexplained swelling, especially when accompanied by other symptoms, should be evaluated promptly.
Main Causes and Risk Factors
While the exact cause of vaginal cancer isn’t always clear, several risk factors have been identified that increase a woman’s likelihood of developing this disease:
Human Papillomavirus (HPV) Infection: HPV, particularly high-risk strains like HPV-16 and HPV-18, is strongly linked to vaginal cancer. The virus can cause cellular changes that may lead to cancer over time.
Age: Vaginal cancer is most commonly diagnosed in women over 60, with the average age of diagnosis being around 60-65 years old. However, certain types can affect younger women.
Vaginal Intraepithelial Neoplasia (VAIN): This precancerous condition involves abnormal cells in the vaginal lining that can potentially develop into cancer if left untreated.
DES Exposure: Women whose mothers took diethylstilbestrol (DES) during pregnancy have a higher risk of developing clear cell adenocarcinoma of the vagina, though this is now rare as DES was discontinued in the 1970s.
Previous History of Cervical Cancer: Women who have had cervical cancer or precancerous cervical conditions have an elevated risk of vaginal cancer.
Smoking: Tobacco use increases the risk of many cancers, including vaginal cancer, as harmful chemicals can damage cellular DNA.
Weakened Immune System: Conditions that compromise the immune system, such as HIV/AIDS or immunosuppressive medications, increase vulnerability to HPV-related cancers.
Chronic Vaginal Irritation: Long-term irritation or inflammation of the vagina may increase cancer risk, though this link is less clearly established.
Prevention Strategies
While not all cases of vaginal cancer can be prevented, several strategies can significantly reduce your risk:
HPV Vaccination: Getting vaccinated against HPV can protect against the strains most commonly associated with vaginal cancer. The vaccine is most effective when given before becoming sexually active, but can still provide benefits to older individuals.
Regular Screening: Attend regular gynecological examinations and Pap smears as recommended by your healthcare provider. These screenings can detect precancerous changes before they develop into cancer.
Safe Sexual Practices: Using condoms and limiting the number of sexual partners can reduce HPV exposure, though condoms don’t provide complete protection against HPV.
Quit Smoking: If you smoke, quitting can reduce your risk of vaginal cancer and many other health problems. Seek support from healthcare professionals to help you quit successfully.
Treat Precancerous Conditions: If diagnosed with VAIN or other precancerous conditions, follow your doctor’s treatment recommendations closely to prevent progression to cancer.
Maintain a Healthy Immune System: Eat a balanced diet, exercise regularly, get adequate sleep, and manage stress to keep your immune system functioning optimally.
Be Aware of Your Body: Pay attention to any unusual symptoms or changes in your vaginal health and report them to your doctor promptly.
Frequently Asked Questions
How common is vaginal cancer?
Vaginal cancer is quite rare, accounting for only 1-2% of all gynecological cancers. Approximately 6,000-7,000 women are diagnosed with vaginal cancer annually in the United States. It’s much less common than cervical, uterine, or ovarian cancer.
Can vaginal cancer be detected early?
Yes, vaginal cancer can be detected early through regular pelvic examinations and Pap smears, which may identify precancerous changes or early-stage cancer. However, many women don’t experience symptoms in the early stages, making routine screening particularly important.
Is vaginal discharge always a sign of cancer?
No, vaginal discharge is normal and healthy in most cases. However, discharge that is foul-smelling, blood-tinged, excessive, or accompanied by other symptoms like bleeding or pain should be evaluated by a healthcare provider to rule out cancer and other conditions.
At what age should I be concerned about vaginal cancer symptoms?
While vaginal cancer is most common in women over 60, it can occur at any age. Women who were exposed to DES in utero may develop a rare form of vaginal cancer in their teens or twenties. Any unusual symptoms should be evaluated regardless of age.
Does having HPV mean I will get vaginal cancer?
No, most women with HPV do not develop vaginal cancer. HPV is very common, and most infections clear on their own. However, persistent infection with high-risk HPV strains can increase cancer risk, which is why vaccination and regular screening are important.
Can vaginal cancer be mistaken for other conditions?
Yes, vaginal cancer symptoms can be similar to those of many other conditions, including vaginal infections, benign cysts, urinary tract infections, or menopause-related changes. This is why proper medical evaluation is essential for accurate diagnosis.
Should I be worried if I have bleeding after intercourse?
Bleeding after intercourse (postcoital bleeding) can have many causes, most of which are benign, such as cervical ectropion or vaginal dryness. However, it can also be a symptom of vaginal or cervical cancer, so it should always be evaluated by a healthcare provider, especially if it occurs repeatedly.
How is vaginal cancer diagnosed?
Vaginal cancer is diagnosed through a combination of pelvic examination, Pap smear, colposcopy (examination with a special magnifying instrument), and biopsy of any suspicious areas. Imaging tests like CT scans or MRIs may be used to determine the extent of the cancer.
Can men transmit anything that causes vaginal cancer?
Yes, men can transmit HPV through sexual contact, which is a major risk factor for vaginal cancer. This is why HPV vaccination is recommended for both males and females, and safe sexual practices are important for cancer prevention.
If I’ve had a hysterectomy, can I still get vaginal cancer?
Yes, women who have had a hysterectomy can still develop vaginal cancer, particularly if the hysterectomy was performed due to cancer or precancerous conditions. It’s important to continue regular gynecological examinations even after hysterectomy.
