Key takeaways

  • There are five main gynaecological cancers: cervical, endometrial (uterine), ovarian, vaginal and vulvar. Cervical is the most common in India; ovarian is the most lethal.
  • Cervical, vaginal and most vulvar cancers are linked to HPV, so the HPV vaccine plus regular cervical screening can prevent the large majority of them.
  • Any postmenopausal bleeding is a red flag for endometrial cancer and needs prompt evaluation, even a single spot of blood.
  • Ovarian cancer has vague symptoms (bloating, feeling full quickly, pelvic pain) and no good screening test, so persistent new symptoms deserve a real workup.
  • Stage at diagnosis drives survival: early-stage gynaecological cancers often have 5-year survival above 90%, while late-stage survival is far lower.
  • Knowing your family history matters. A strong history of ovarian, breast, colon or uterine cancer may justify genetic counselling and testing.

Cervical Cancer: The Most Common and Most Preventable

Risk factors

Beyond persistent HPV infection, factors that raise cervical cancer risk include smoking, a weakened immune system (including HIV), having more sexual partners or partners who do, a history of many full-term pregnancies, and very long-term combined oral contraceptive use (the small added risk falls back to normal after stopping). HPV is the central cause; these factors mainly affect whether an infection persists and progresses.

Prevention: vaccine + screening

Prevention has two pillars. First, the HPV vaccine, which is most effective when given at ages 9 to 14, before any HPV exposure, but is recommended through age 26 and reasonable up to 45 after a discussion with your doctor. India now has Cervavac, an indigenous, affordable vaccine, alongside Gardasil 9. Second, cervical screening. Indian guidance broadly follows: a Pap smear every 3 years from age 21 to 29, then from age 30 a Pap every 3 years, HPV testing every 5 years, or co-testing every 5 years, up to age 65. In community settings, visual inspection with acetic acid (VIA) is sometimes used. Screening is free at many government health centres and under Ayushman Bharat. Even vaccinated women still need screening, because no vaccine covers every cancer-causing HPV type.

Endometrial (Uterine) Cancer: The Rising One

Risk factors

The strongest modifiable risk factor is obesity, because fat tissue produces extra oestrogen. Type 2 diabetes, polycystic ovary syndrome (PCOS) with long-term skipped periods, never having been pregnant, early periods and late menopause, oestrogen-only hormone therapy in a woman who still has her uterus, and the breast cancer drug tamoxifen all raise risk. So does Lynch syndrome, an inherited condition that also raises colon cancer risk. Combined oral contraceptives, pregnancy, breastfeeding and the hormonal IUD all lower endometrial cancer risk.

The warning sign that matters most

Postmenopausal bleeding, any vaginal bleeding 12 months or more after your last period, is the cardinal warning sign. While most cases turn out to be benign, roughly 1 in 10 women with postmenopausal bleeding have endometrial cancer, so it always needs evaluation. Do not dismiss it as "just spotting". Before menopause, heavy, prolonged or between-period bleeding also deserves attention, especially with risk factors. Workup usually starts with a transvaginal ultrasound to measure the lining thickness, followed by an endometrial biopsy, a quick office procedure, when needed.

Ovarian Cancer: The Quietest and Most Dangerous

Symptoms to take seriously

The symptoms are easy to brush off: persistent bloating, feeling full quickly, pelvic or abdominal pain, needing to urinate more often, and fatigue. The pattern that should prompt a doctor's visit is symptoms that are new for you, persistent (more than about 12 days a month), and progressive. Do not let these be waved away as "just gas" or IBS without a proper look, which usually includes a pelvic exam, pelvic ultrasound and a CA-125 blood test.

Family history and BRCA

Inherited gene faults, especially BRCA1 and BRCA2, account for a meaningful share of ovarian cancers and are highly actionable. A woman who knows she carries one can dramatically lower her risk through risk-reducing surgery after completing her family. Consider genetic counselling and testing if your family has ovarian cancer at any age, breast cancer under 50, multiple cancers, or a known gene mutation. In India, BRCA testing has become far more affordable than it once was.

Why there is no routine screening

For average-risk women, screening with CA-125 and ultrasound is not recommended, because large trials showed it does not reduce deaths and leads to unnecessary surgeries. For high-risk women, specialist surveillance may be used as a bridge to risk-reducing surgery, which remains the most effective protection.

Vaginal Cancer: Rare but Worth Knowing

Vaginal cancer, meaning cancer that begins in the vagina itself rather than spreading there from elsewhere, is rare, making up only about 1 to 2% of gynaecological cancers. Because it is uncommon, diagnosis can be delayed, which is one more reason to act on unusual symptoms rather than wait.

Most vaginal cancers are squamous cell carcinomas, and like cervical cancer, the majority are caused by persistent HPV infection. That means the same prevention works: the HPV vaccine and cervical screening protect against vaginal cancer too. Risk rises with age (most cases occur after 60), smoking, a weakened immune system, prior pelvic radiation, and a history of cervical precancer or cancer.

Symptoms overlap with cervical cancer: abnormal vaginal bleeding (after sex, between periods, or after menopause), unusual or foul-smelling discharge, pelvic pain, pain during sex, or a lump in the vagina. A precancerous stage, called VAIN, can be found and treated before cancer develops, which is why women with a history of cervical precancer need ongoing follow-up.

Vulvar Cancer: The Often-Overlooked One

Symptoms and self-examination

See a doctor for vulvar symptoms that persist beyond a few weeks: itching that won't settle, pain or burning, a lump, an ulcer or sore that doesn't heal, a mole that changes in size, shape or colour (important for melanoma), unexplained bleeding, or skin colour and texture changes. Periodic vulvar self-examination with a mirror, looking and gently feeling for changes, is appropriate, sensible self-care. Persistent vulvar pain during sex also deserves evaluation; our guide to painful sex (dyspareunia) explains the common causes.

Treating lichen sclerosus lowers risk

Lichen sclerosus appears as white, thin, fragile vulvar skin with itching and sometimes architectural changes. The standard treatment is a potent topical steroid (clobetasol), which controls symptoms and may reduce cancer risk by calming the chronic inflammation that drives it. Long-term follow-up with prompt biopsy of any suspicious area is important.

Prevention: What Indian Women Can Actually Do

  • Get the HPV vaccine, ideally for daughters at ages 9 to 14, and for yourself up to age 26 (and possibly later after discussion). This is the single most powerful step against cervical, vaginal and many vulvar cancers.
  • Screen regularly. A Pap smear or HPV test on schedule from age 21 to 65 catches cervical precancer before it becomes cancer.
  • Keep a healthy weight and manage diabetes and PCOS. This directly lowers endometrial cancer risk; our guide to weight management in PCOS can help.
  • Know your family history and seek genetic counselling if it includes ovarian, breast, colon or uterine cancer.
  • Don't smoke, and limit alcohol, both raise the risk of several cancers.
  • Use the protective effects of pregnancy, breastfeeding and, for some women, combined contraceptives wisely, as part of broader life and contraception choices.
  • See a gynaecologist regularly and act on warning symptoms early.

When to See a Doctor: Warning Symptoms That Need Prompt Evaluation

  • Any postmenopausal bleeding, even a single spot, the top warning sign for endometrial cancer.
  • Bleeding between periods, after sex, or periods that are suddenly much heavier or longer, especially over 40.
  • Persistent abnormal discharge that doesn't clear with treatment, particularly if foul-smelling, watery or blood-tinged. Our guide to normal vs abnormal discharge can help you tell the difference.
  • Persistent bloating, feeling full quickly, or new pelvic or abdominal pain that won't settle.
  • A vulvar lump, sore or ulcer that doesn't heal, persistent itching, or a changing mole.
  • Pain during sex that is new or getting worse, or ongoing chronic pelvic pain.
  • Unexplained weight loss, persistent fatigue, leg swelling, or a new change in bowel or bladder habits.

Frequently asked questions

Which gynaecological cancer is most common in India?

Cervical cancer is the most common gynaecological cancer in Indian women and one of the leading cancers in women overall. It is also one of the most preventable, through HPV vaccination and regular cervical screening.

Can the HPV vaccine prevent gynaecological cancer?

Yes. Because HPV causes nearly all cervical cancers and most vaginal and many vulvar cancers, the HPV vaccine can prevent the large majority of these cancers. It works best given at ages 9 to 14, before HPV exposure, but is still recommended through age 26 and may be reasonable up to 45 after discussion with your doctor.

What is the most important early warning sign of uterine (endometrial) cancer?

Postmenopausal bleeding, any vaginal bleeding 12 months or more after your last period. Even a single spot needs prompt evaluation. About 1 in 10 such cases turn out to be endometrial cancer, and most are highly treatable when caught early.

Is there a screening test for ovarian cancer?

Not for average-risk women. Trials show that CA-125 and ultrasound screening does not reduce deaths and causes unnecessary surgeries. The best protection for high-risk women (such as BRCA carriers) is genetic counselling and risk-reducing surgery after completing their family. For everyone else, taking persistent vague symptoms seriously is what matters.

Do I still need Pap smears if I had the HPV vaccine?

Yes. The vaccine does not cover every cancer-causing HPV type, so vaccinated women should continue cervical screening on the usual schedule from age 21 to 65.

When should I consider genetic testing for gynaecological cancer?

Consider genetic counselling if your family has ovarian cancer at any age, breast cancer under 50, multiple cancers in one person or family, or a known cancer-predisposition gene such as BRCA or Lynch syndrome. Testing is now far more affordable in India than it used to be.
