Understanding the Different Types of Gynaecological Cancer
September is Gynaecological Cancer Awareness Month, a time dedicated to raising awareness about the five gynaecological cancers, cervical, ovarian, vaginal, endometrial and vulvar. The aim is to increase understanding, spark important conversations, and encourage early detection, which can make a lifesaving difference. By learning more about the symptoms, risk factors and prevention, we can help break down the stigma around gynae health and ensure more people feel confident seeking medical advice when something doesn’t feel right.
Importance of early detection
Gynaecological cancer is relatively common but will often go undetected until it reaches an advance stage. This makes early detection vital in fighting the disease. Early detection directly correlates to survival rates; it is the most powerful tool in combating cancer of any kind.
Genetics and Cancer: What to Know
When it comes to gynaecological cancers, understanding your risk factors is key to early detection and prevention. Many people mistakenly believe that cancer itself is inherited, that if a parents had cancer, their child is destined to develop the same disease. This is not the case. Cancers are not directly passed down through families. Instead, what can be inherited are certain risk factors, including genetic mutations. These may increase your likelihood of developing specific types of cancer.
One of the most well-known genetic mutations is the BRCA mutation. This genetic alteration significantly increases the risk of breast and ovarian cancer. While carrying a genetic mutation does not guarantee cancer, knowing your family history and understanding the genetic risk factors can help both you and your healthcare practitioner make informed decisions about screening, prevention and early detection.
While genetics can play a key role in your risk, it is also important to understand that gynaecological cancers are not all the same. The five main types of gynaecological cancers may share some similarities. Each type comes with its own specific risk factors, symptoms and most importantly, treatment options. Understanding the differences is key to recognising warning signs early and seeking effective treatment.
- Cervical Cancer
What is Cervical cancer?
Cervical cancer is a type of gynaecological cancer that develops in the cervix. The cervix sits in the lower part of the uterus and connects to the vagina. It is most often caused by the persistent infection of the human papillomavirus (HPV). This virus is often transmitted through sexual contact. While the body’s immune system usually clears the HPV virus on its own, in some cases it can persist and trigger changes in cervical cells. Over time, these changes then lead to abnormal cell growth, and if these cells are left untreated, the development of cervical cancer can occur.
Early signs to watch for can include unusual discharge, bleeding (especially after sex), odour, or pelvic pain. Very early on, symptoms may not be presented, making it harder to diagnose.
Risk Factors of Cervical Cancer
While cervical cancer is most diagnosed in women over thirty, it can affect women of all ages. Several risk factors are associated with this gynaecological cancer, including lifestyle, genetic, and viral influences.
- Smoking tobacco
Women who smoke tobacco have an increased risk of developing cervical cancer. Smoking can weaken the body’s immune system, making it harder to clear HPV from the system. When HPV persists in smokers, it has a greater chance of causing abnormal changes in cervical cells, which can eventually develop into cervical cancer. - Increased number of sexual partners
HPV, the main cause of cervical cancer, is a sexually transmitter virus. Women with multiple sexual partners have a higher risk of being exposed to HPV. Since the virus is so common, a person may be carrying the virus without knowing it. It is also possible for women to develop HPV-related changes in the cervix even if they have only ever had one sexual partner, making regular cervical screening and HPV awareness essential for all sexually active women. - Early sexual activity
Researchers have found that individuals who are sexually active from a younger age are at risk of developing cervical cancer. This is attributed to the changes that occur to the cervix during puberty, which leave it vulnerable to damage. - Weakened immune system
Cervical cancer usually develops slowly, it typically takes 15-20 years for abnormal cells to present when the HPV is left untreated. However, women with a weakened immune system are at a higher risk for abnormal cells to form more quickly. For example, women with HIV may experience changes in cervical cells much earlier, sometimes within 5-10 years, due to their compromised immune system.
Prevention and early detection
The good news is that most cases of cervical cancer can be prevented. One of the most effective ways to lower your risk is by protecting against human papillomavirus (HPV), the main cause of cervical cancer. HPV vaccination offers strong protection and is most effective when given at a younger age, ideally before becoming sexually active.
Raising awareness is key. Encouraging people to attend cervical screening appointments and to receive the HPV vaccine can make a lifesaving difference. Cervical cancer is a highly treatable gynaecological cancer when it is found early. This is why regular Pap smears, performed at the intervals recommended by your healthcare practitioner, are essential for prevention and early detection.
2. Ovarian Cancer
What is Ovarian Cancer?
Ovarian cancer is a type of gynaecological cancer that can affect anyone born with a female reproductive system. The ovaries are two small organs that hold and release eggs for human reproduction. It develops when abnormal cells grow and multiply in the ovaries, fallopian tubes, or the peritoneum, which is the thin membrane lining the abdominal cavity. It mostly affects women over the age of 50, but it can affect anyone with ovaries, both older and younger. Common warning signs to look out for include bloating, frequent or urgent urination, pain in the abdomen or pelvis, and difficulty eating or feeling full fast. In most cases, ovarian cancer is diagnosed late, making it harder to treat. Early diagnosis is essential in having a successful treatment.
Risk Factors of Ovarian Cancer
- Inherited genetic mutations
While ovarian cancer itself is not directly inherited, certain genetic risk factors can increase the likelihood of developing the disease. One of the most significant is the BRCA gene mutation. Women who inherit a BRCA1 or BRCA2 mutation have a much higher risk of developing ovarian cancer compared to those without the mutation. These inherited mutations also raise the risk of breast cancer, which is why genetic testing and family history are important considerations in understanding ovarian cancer risk. - Age
Like many other cancers, the risk of developing ovarian cancer increases with age. Most cases are diagnosed in women over 50. While ovarian cancer can occur at any age, it is most common after menopause, making regular awareness of symptoms especially important for women in midlife and beyond. - Overweight or obesity
Women who are overweight or obese have a higher risk of developing ovarian cancer. Excess body weight can affect hormone levels and increase inflammation in the body, both of which may contribute to cancer development. However, being overweight does not mean you will definitely develop ovarian cancer. Maintaining a healthy lifestyle with balanced nutrition and regular physical activity can help reduce overall cancer risk and support better reproductive health.
Prevention and early detection
One way to help lower the risk of ovarian cancer is by using the combined oral contraceptive pill. Research shows that taking the pill can significantly reduce the likelihood of developing ovarian cancer, especially with long-term use.
Because ovarian cancer is often diagnosed at a later stage, early detection is vital. When found early, ovarian cancer is much easier to treat, and survival rates improve greatly. Paying attention to symptoms such as bloating, pelvic pain, or changes in appetite, and discussing any concerns with your healthcare practitioner can make a lifesaving difference.
3. Endometrial Cancer
What is Endometrial Cancer?
Endometrial cancer, also known as uterine cancer, is the most common gynaecological cancer. The cancer begins in the first layer of the uterus lining, the endometrium. This type of gynaecological cancer presents with symptoms and is often found in the early stages. Early symptoms may include vaginal bleeding, spotting, or unusual discharge. Because early detection greatly improves the chances of successful treatment, it is crucial to be aware of both the risk factors and the warning signs of endometrial cancer.
Risk Factors of Endometrial Cancer
- Estrogen-only hormone replacement therapy
Estrogen replacement therapy is used to relieve menopause symptoms. When it is administered without progesterone, it is called unopposed estrogen therapy. This risk will increase with the duration of using estrogen replacement therapy. - Age
The likelihood of developing endometrial cancer rises as a person gets older. While it can occur at any age, it is seen most often in women who have gone through menopause, with the majority of cases diagnosed in those in their 50s and 60s. Hormonal changes, the natural aging process, and certain health factors all contribute to this increased risk after menopause. - Obesity
Fat tissue plays an active role in hormone production. In people with higher amounts of body fat, certain hormones are converted into estrogen within the fat tissue. This added estrogen can stimulate the lining of the uterus (endometrium), which increases the risk of developing endometrial cancer. The more fat tissue a person has, the greater the amount of estrogen that is produced, and the higher the potential risk. This is why obesity is considered one of the strongest risk factors for endometrial cancer.
Prevention and early detection
While there is no standard screening test for endometrial (uterine) cancer, early detection depends on recognising symptoms and seeking timely medical care. The Pap test (Pap smear) does not detect uterine cancer; it only screens for cervical cancer, so women should be alert to warning signs such as abnormal vaginal bleeding after menopause, unusual discharge, or persistent pelvic pain, and report them to their healthcare provider. If endometrial cancer is suspected, your healthcare practitioner may review your medical history and risk factors, perform a pelvic exam, and order imaging or an endometrial biopsy.
Although endometrial cancer cannot always be prevented, you can reduce your risk by maintaining a healthy weight, managing diabetes, discussing progesterone-based or combined hormonal contraceptives with your doctor, and carefully weighing the benefits and risks of estrogen replacement therapy (ERT) if you are considering it for menopause symptoms. Paying attention to risk factors and possible signs of disease is the most effective strategy for prevention and early detection, and seeking medical advice without delay greatly improves treatment outcomes.
4. Vaginal Cancer
What is Vaginal Cancer?
Vaginal cancer is a rare type of gynaecologic cancer that typically starts in the cells lining the vagina, the muscular canal connecting the cervix (the lower part of the uterus) to the vulva (external genitals). Although it accounts for only 1–2% of all gynecological cancers, early detection is critical for effective treatment. There are several types of vaginal cancer, classified based on the cells where the cancer begins, including squamous cell carcinoma, adenocarcinoma, melanoma, and sarcoma. Symptoms can sometimes include abnormal vaginal bleeding, especially after sex, unusual vaginal discharge, pelvic pain, or painful urination, but in many cases, vaginal cancer may not cause noticeable symptoms at all. This makes regular check-ups and screenings with your healthcare provider essential for early detection, even in the absence of symptoms, helping to improve outcomes and increase treatment options for women with vaginal cancer.
Risk Factors of Vaginal Cancer
- Human papillomavirus
Human papillomavirus (HPV) is a very common viral infection that spreads through close skin-to-skin contact, most often during sexual activity. For most individuals, the virus causes no symptoms, clears up on its own without treatment, and often goes unnoticed. When left untreated, HPV infections can lead to abnormal changes in the vaginal lining. These changes are known as vaginal intraepithelial neoplasia (VAIN) and are precancerous cells. If these changes are not monitored or treated, they may slightly increase the risk of developing vaginal cancer. HPV can lead to the development of both cervical and vaginal cancer. - History of cervical cancer or CIN
People who have had cervical cancer or cervical intraepithelial neoplasia (CIN) have a higher risk of developing vaginal cancer. This increased risk is most likely related to HPV, the underlying cause of most cervical cancers and CIN. Vaginal cancer can develop in some individuals after treatment for cervical cancer. Having these abnormal cells in the cervix, known as cervical dysplasia, may also increase the risk of developing vaginal cancer. Smoking may further raise the risk, but it is important to note that most people with a history of cervical cancer or CIN will never develop vaginal cancer. - Exposure to miscarriage prevention medicine
Exposure to diethylstilbestrol (DES) before birth can increase the risk of developing vaginal cancer later in life. ES is a synthetic estrogen that was prescribed to some pregnant women between the 1940s and 1970s to prevent miscarriage, premature labour, and related pregnancy complications. Daughters of women who took DES during pregnancy have a higher risk of developing a rare type of vaginal cancer called clear cell adenocarcinoma. While DES-related vaginal cancer is uncommon, women with this prenatal exposure should inform their healthcare provider and may need more careful monitoring for early detection of abnormalities. It is important to note that women do not need to have been exposed to DES for clear cell adenocarcinoma to develop. In fact, cases of this type of vaginal cancer were reported even before DES was ever used.
Prevention and early detection
Early detection and prevention of vaginal and cervical abnormalities usually starts with a pelvic exam and a Pap smear (Pap test). During a Pap smear, your healthcare provider gently collects cells from the cervix using a small brush or spatula, which are then sent to a lab to check for signs of cancer or HPV infection. If abnormal cells are detected, additional tests such as a colposcopy and a vaginal biopsy may be recommended, with a biopsy being the only procedure that can definitively confirm a cancer diagnosis. Maintaining regular screenings as advised by your healthcare provider and promptly following up on any abnormal results is crucial for detecting potential problems early, even before symptoms appear, significantly increasing the chances of successful treatment.
In addition to regular Pap smears and pelvic exams, one of the most effective ways to help prevent vaginal cancer is through the HPV vaccine. Healthcare practitioners also recommend avoiding smoking, as tobacco use increases the risk of many types of cancer. While vaginal cancer is rare, smoking can elevate your overall risk and contribute to factors that make cancer more likely to develop.
5. Vulvar Cancer
What is Vulvar Cancer?
Vulvar cancer affects the outer female genitals and can develop in any part of the vulva, most commonly the labia majora, labia minora, or perineum. This type of cancer often develops slowly over several years. There are several types of vulvar cancer, with the most common being vulvar squamous cell carcinoma and vulvar melanoma. About 90% of vulvar cancers are squamous cell carcinomas, which develop in the surface cells of the vulvar skin. In contrast, around 5% are melanomas, which grow more rapidly and carry a higher risk of spreading to other parts of the body. It is important to note that the symptoms of vulvar cancer can vary depending on where the cancer develops. However, the most common type, squamous cell carcinoma, often causes noticeable signs. These can include changes in skin color, such as areas that appear darker or lighter than usual, or patches of white skin; thickened or roughened skin; and growths like lumps, wart-like bumps, or ulcers that do not heal. Other symptoms may include persistent itching or burning, unexplained bleeding not related to menstruation, and tenderness or pain, which can occur during sex or while urinating.
Risk factors of vulvar cancer
- Human papillomavirus
Not all strains of human papillomavirus (HPV) cause cancer, but certain high-risk types can lead to cellular changes that may eventually develop into vulvar cancer. Researchers have found that approximately half of all vulvar squamous cell carcinoma cases are linked to HPV. There are various different strains of HPV, researchers have found that HPV type 16, type 33 and type 18 are the most linked to the development of vulvar cancer. - Vulvar intraepithelial neoplasia (VIN)
HPV infection can also cause precancerous changes in the vulvar skin, known as vulvar intraepithelial neoplasia (VIN). VIN refers to precancerous changes in the top layer of skin covering the vulva, which can sometimes develop into vulvar cancer over time. If you are diagnosed with VIN, your healthcare practitioner may recommend treatment to reduce the risk of progression. Options can include regular monitoring, laser therapy, or surgical removal of the affected area. - Weakened Immune System
Women with a weakened immune system, or HIV, are at a higher risk if developing vulvar cancer. HIV is the virus that causes AIDS (acquired immune deficiency syndrome). It weakens the immune system, making it harder for the body to fight off infections, including HPV. - Lichen sclerosus
Lichen sclerosus is a chronic (long-term) skin condition that causes inflammation, itching, and changes to the skin of the vulva. It often effects women over the age of 60. Women with lichen sclerosus may develop a precancerous condition called differentiated vulvar intraepithelial neoplasia (dVIN). This condition affects the vulvar skin and, if left untreated, can progress to vulvar cancer over time. Early diagnosis and appropriate treatment of dVIN are important to reduce the risk of cancer development.
Prevention and early detection
One of the most effective ways to lower the risk of vulvar cancer is through the HPV vaccination. The vaccination helps protect against high-risk HPV types 16 and 18 that are linked to vulvar cancer. Although there is currently no routine screening test for vulvar cancer, staying vigilant about your health is crucial. Performing regular self-checks and paying attention to any new or persistent symptoms, such as changes in skin colour, lumps, growths, or unexplained itching, can help detect potential problems early, improving the chances of successful treatment.
Period Products and Gynaecological Cancer
When it comes to gynaecological health and cancer prevention, the role of menstrual products is often overlooked. Yet what we use every month matters. The vagina and vulva are highly absorbent, making them especially vulnerable to chemicals and toxins present in conventional pads and tampons. Recent reports revealed alarming findings: toxic pesticide levels in tampons, in some cases 40 times higher than the legal limit for drinking water. Alongside pesticides, other harmful substances such as PFAS, known as “forever chemicals” because they persist in the body and environment, have also been detected in menstrual hygiene products. To put this into perspective, the average person who menstruates will use around 11,000 disposable period products in their lifetime. With products designed for such frequent, intimate use now shown to contain dangerous chemicals, the potential health risks are deeply concerning. PFAS, commonly used in food packaging, can break down and accumulate in the body over time, and have been linked to hormonal disruption, weakened immune function, and an increased risk of certain cancers. Although there are still limited studies directly connecting menstrual products to gynaecological cancers, researchers have found very high levels of glyphosate, a pesticide already linked to cancer, in products widely available on store shelves. While tampons are most commonly implicated, traces of harmful chemicals have also been detected in pads and other menstrual products. And while scented tampons, pads, and so-called “feminine wipes” may not be directly tied to cancer, they can still irritate sensitive tissue, disrupt the vaginal microbiome, and contribute to other gynaecological health problems.

In conclusion
In conclusion, understanding the different types of gynaecological cancers, cervical, ovarian, endometrial, vaginal, and vulvar, is essential for awareness, prevention, and early detection. While each type of cancer has its own set of risk factors, symptoms, and treatment options, early detection remains the most powerful tool in improving outcomes and survival rates. Strategies such as regular screenings, HPV vaccination, maintaining a healthy lifestyle, and monitoring for unusual changes in the reproductive system can all help reduce risk and catch disease early. It is important to note, however, that having one or more risk factors does not mean you will develop cancer, and conversely, it is possible for someone with no known risk factors to be diagnosed. By staying informed, attentive to your body, and proactive in seeking medical advice when something feels abnormal, you can take meaningful steps to protect your health and encourage open conversations about gynaecological wellness.
