Uterine Cancer

Uterine cancer is a serious condition that affects the female reproductive system. It is crucial for women to be aware of the signs and symptoms of uterine cancer, as early detection and treatment can significantly improve the chances of a successful outcome. In this article, we will explore the different aspects of uterine cancer, including its types, symptoms, and prognosis.

What is Uterine Cancer?

Uterine cancer is a general term that encompasses cancers that originate in the uterus, the hollow, pear-shaped pelvic organ where foetal development occurs. The two main types of uterine cancer are endometrial cancer, which develops in the inner lining of the uterus called the endometrium, and uterine sarcoma, which starts in the muscles or other tissues of the uterus. Understanding the differences between these types is crucial for accurate diagnosis and treatment.

There are two main types of uterine cancer:

• Endometrial cancer: This is the most common type of uterine cancer, accounting for about 95% of all cases. Endometrial cancer starts in the cells that make up the endometrium, the lining of the uterus. It can be further divided into different subtypes based on the histologic type, such as adenocarcinoma, squamous cell carcinoma, and serous carcinoma.

• Uterine sarcoma: This is a rare type of uterine cancer, accounting for about 5-10% of all cases. Uterine sarcoma starts in the muscles or other tissues in the uterus. It can be more aggressive than endometrial cancer and may require different treatment approaches.

Some of the early warning signs of uterine cancer include:

• Abnormal vaginal bleeding, such as bleeding after menopause, between periods, or noticeable changes in menstrual flow

• Pelvic pain or discomfort

• Unusual, non-bloody vaginal discharge

• Difficulty urinating

• Abdominal pain

• Unexplained weight loss

• Changes in bowel habits

The symptoms of uterine cancer may include:

• Abnormal vaginal bleeding: This is the most common symptom of uterine cancer. It may present as heavy periods, bleeding between periods, or bleeding after menopause.

• Pelvic pain: Many women experience persistent pain or discomfort in the pelvic area. This pain can sometimes be mistaken for menstrual cramps.

• Unexplained weight loss: Sudden and unexplained weight loss can be a concerning sign. It is particularly worrisome when accompanied by other symptoms.

• Changes in menstrual cycle: Women may notice irregular periods or changes in flow. This includes periods that are significantly heavier or last longer than usual.

• Enlarged uterus or ovaries: A feeling of fullness or pressure in the abdomen can develop. This may be accompanied by visible swelling.

• Urinary symptoms: Some women experience frequent urination, urgency, or difficulty urinating. These symptoms can arise if the cancer affects nearby structures.

• Gastrointestinal issues: Symptoms such as bloating, nausea, or changes in bowel habits may also arise. These can be subtle but should not be ignored.

Uterine cancer is staged based on how far the cancer cells have spread from the inner lining of the uterus (the endometrium). Here are the general stages:

• Stage 1: Cancer cells are present only inside the uterus, specifically in the endometrium, which is the inner lining of the uterus.

• Stage 2: Cancer cells have spread to the connective tissue of the cervix but not outside the uterus. No cancer cells are found in nearby lymph nodes at this stage.

• Stage 3: Cancer cells have spread to tissues outside the uterus but not to the rectum or bladder. Cancer cells may have spread to nearby lymph nodes, the surface of the uterus, ovaries, vagina, or tissues in the pelvis.

• Stage 4: Cancer cells have spread to the inner lining of the rectum, bladder, or other distant parts of the body, such as the lungs or liver. Cancer cells may also have spread to distant lymph nodes. This is the most advanced stage of uterine cancer.

Uterine cancer, primarily affecting the lining of the uterus (endometrial cancer), has several known risk factors and potential causes:

• Hormonal imbalance: Prolonged exposure to oestrogen without progesterone can lead to abnormal cell growth in the uterus. Conditions like polycystic ovary syndrome (PCOS) and hormone replacement therapy can contribute to this imbalance.

• Age: Uterine cancer is more common in women over 50, particularly after menopause. The risk increases significantly after age 60.

• Obesity: Obesity is a major risk factor, as fat tissue produces oestrogen. This additional oestrogen can increase the likelihood of developing uterine cancer.

• Family history and genetics: A family history of uterine, breast, or colon cancers may elevate risk. Genetic syndromes, such as Lynch syndrome (hereditary non-polyposis colorectal cancer), also increase susceptibility.

• Reproductive history: Irregular menstrual cycles, early onset of menstruation, late menopause, or not having children can increase risk. Women who have not been pregnant may have a higher chance of developing uterine cancer.

• Medical conditions: Conditions such as diabetes and hypertension can contribute to the risk. Additionally, having conditions that cause high oestrogen levels, like endometrial hyperplasia, can be a precursor to cancer.

• Lifestyle factors: Poor diet, lack of physical activity, and smoking can contribute to obesity and hormonal imbalances, indirectly increasing the risk of uterine cancer.

• Radiation therapy: Women who have undergone radiation treatment to the pelvis for other cancers may have an increased risk of developing uterine cancer later on.

Certain factors are associated with a higher likelihood of getting uterine cancer:

• Older age, with most cases diagnosed after menopause

• Being overweight or obese, which increases oestrogen levels

• Starting menstruation early or going through menopause late, leading to more lifetime oestrogen exposure

• Having an inherited genetic predisposition, such as Lynch syndrome or a strong family history of uterine or colon cancer

• Never having been pregnant

• Undergoing oestrogen-only hormone replacement therapy

• Having had radiation therapy to the pelvis previously

Uterine cancer, particularly endometrial cancer, can lead to several complications, both from the disease itself and the treatments. Common complications include:

• Metastasis: Uterine cancer may spread to other parts of the body, such as the ovaries, bladder, intestines, or lungs. This spread complicates treatment and can worsen the prognosis.

• Anaemia: Patients may experience anaemia as a result of heavy bleeding associated with the cancer. Symptoms of anaemia include fatigue, weakness, and pale skin, all of which can negatively impact daily activities.

• Lymphoedema: If lymph nodes are removed or damaged during treatment, patients may develop lymphoedema. This condition leads to swelling in the legs or pelvis and can cause discomfort and mobility issues.

• Surgical complications: Surgery, such as a hysterectomy, carries inherent risks, including infection, blood loss, and damage to surrounding organs. Recovery from surgery may involve pain and a prolonged healing process.

• Radiation side effects: Patients undergoing radiation therapy may experience side effects such as skin irritation, fatigue, and gastrointestinal issues. These effects can significantly impact quality of life during treatment.

• Emotional and psychological impact: A diagnosis of uterine cancer can lead to anxiety, depression, and changes in body image. Many patients find it helpful to seek support from mental health professionals to cope with these challenges.

• Fertility issues: Younger women may face challenges related to fertility as a result of treatment. It is essential to discuss options for preserving eggs or embryos before beginning treatment.

• Recurrence: Even after successful treatment, there is a risk of cancer recurrence. Regular follow-ups and monitoring are crucial to detecting any signs of recurrence early.

Although uterine cancer cannot be completely prevented, there are steps that can reduce the risk of developing this disease. Here are some strategies for prevention:

• Maintain a healthy weight: Obesity is a major risk factor for uterine cancer. Adopting a balanced diet and engaging in regular physical activity can help maintain a healthy weight.

• Eat a balanced diet: A diet rich in fruits, vegetables, whole grains, and lean proteins may lower the risk. Limiting processed foods, red meats, and high-fat dairy products is also beneficial.

• Regular exercise: Engaging in regular physical activity helps manage weight and balance hormone levels. Aim for at least 150 minutes of moderate exercise per week.

• Control blood sugar levels: Managing conditions like diabetes can reduce the risk of uterine cancer. This may involve diet, exercise, and medication as prescribed by a doctor.

• Hormonal balance: For women with conditions that cause high oestrogen levels, such as polycystic ovary syndrome (PCOS), discussing management options with a doctor can be important. Hormonal therapies should be carefully considered.

• Use of birth control: Oral contraceptives may lower the risk of endometrial cancer. Discussing the benefits and risks with a doctor can help determine if this option is suitable.

• Regular check-ups and screenings: Routine gynaecological exams and screenings can help identify any abnormal changes early. Women should discuss their individual risk factors with their doctor.

• Smoking cessation: Quitting smoking can improve overall health and may reduce the risk of several cancers, including uterine cancer.

Diagnosing uterine cancer involves a combination of medical history evaluation, physical examinations, and various diagnostic tests. Here are the key steps in the diagnostic process:

• Medical history: Doctors will start by taking a detailed medical history. This includes asking about symptoms, menstrual history, family history of cancer, and any other relevant health issues.

• Physical examination: A pelvic exam allows the provider to check for abnormalities in the uterus and surrounding organs. This examination may reveal signs of enlargement or other issues.

• Ultrasound: This test uses sound waves to create images of the uterus and can help identify abnormalities such as thickening of the endometrium.

• Magnetic resonance imaging: MRI provides detailed images of the uterus and surrounding tissues, helping to assess the extent of cancer.

• Computed tomography scan: A CT scan may be used to check for metastasis to other organs.

• Endometrial biopsy: This procedure involves taking a small sample of the endometrial tissue to check for cancer cells. It can often be done in a doctor's office and provides critical information for diagnosis.

• Dilation and curettage: If an endometrial biopsy is inconclusive, a D&C may be performed. This surgical procedure involves scraping the lining of the uterus to obtain more tissue for examination.

• Hysteroscopy: In this procedure, a thin, lighted tube (hysteroscope) is inserted through the vagina into the uterus. It allows the doctor to visualise the uterine lining and take biopsies if necessary.

• Genetic testing: For women with a family history of uterine or related cancers, genetic testing for mutations (such as those in the BRCA genes or Lynch syndrome) may be recommended.

Treatment for uterine cancer is personalised, considering factors such as stage, type, grade, and the patient’s age and health. The main treatment options include:

• Surgery: Surgery is the primary treatment, often involving a hysterectomy, which removes the uterus and may include the cervix, fallopian tubes, ovaries, and nearby lymph nodes. Types of hysterectomies include total hysterectomy and radical hysterectomy.

• Radiation therapy: Radiation therapy can be administered before or after surgery. It targets cancer cells using external radiation or internal brachytherapy, where a radiation device is placed inside the vagina.

• Chemotherapy: Chemotherapy uses medicines to kill or damage cancer cells. It can be given intravenously or orally and is typically used post-surgery to reduce recurrence risk or pre-surgery to shrink tumours. It is also used for advanced cancer.

• Hormone therapy: This therapy lowers hormone levels or blocks their effects, targeting cancers that rely on hormones for growth. It is particularly useful for advanced endometrial cancer.

• Targeted therapy and immunotherapy: Targeted therapy attacks specific cancer cell chemicals, while immunotherapy enhances the immune response against cancer. These are often used with chemotherapy for advanced uterine cancers, including endometrial cancer and uterine sarcomas.

Living with uterine cancer can be a challenging experience that impacts various aspects of life. Here are some key considerations and strategies for managing daily life after a diagnosis:

• Regular check-ups with your doctor are essential to monitor for any signs of cancer recurrence and address any symptoms or concerns you may have.

• Seek support from family, friends, or support groups to help cope with the emotional impact of living with uterine cancer.

• Maintain a healthy diet, exercise regularly, and avoid smoking and excessive alcohol consumption to improve your overall health and well-being.

• Perform pelvic floor exercises to strengthen the muscles that support the bladder, bowel, and uterus, which may be weakened after treatment.

• Manage treatment side effects proactively. Work with your doctor to find strategies to alleviate side effects like fatigue, nausea, or pain.

If you experience any symptoms of uterine cancer, such as abnormal vaginal bleeding, pelvic pain, or unexplained weight loss, it is important to see your doctor promptly. Early detection and treatment can significantly improve the prognosis for uterine cancer. Additionally, if you have any concerns or questions about your treatment or experience any new or worsening symptoms, do not hesitate to contact your doctor.
