Endometrial Cancer

Endometrial cancer, also known as uterine cancer, is a serious health concern affecting women worldwide. This type of cancer develops in the lining of the uterus, called the endometrium. While it may not receive as much attention as other forms of cancer, its impact on women's health should not be underestimated. Early detection and understanding the risk factors associated with endometrial cancer are crucial in improving outcomes for patients. 

Symptoms of Endometrial cancer

If you suspect you or someone else is experiencing Endometrial cancer, it is crucial to seek immediate medical attention by calling emergency services or consult with a Cancer Specialist.

Causes of Endometrial Cancer

Hormonal Imbalance: High levels of estrogen without enough progesterone can increase the risk of endometrial cancer.

Age: Most endometrial cancer cases occur in women over the age of 50.

Obesity: Excess body fat can lead to higher estrogen levels, raising the risk.

Genetic Factors: Inherited conditions, such as Lynch syndrome, increase the likelihood of endometrial cancer.

Early Menstruation or Late Menopause: Longer exposure to estrogen over a lifetime increases risk.

Polycystic Ovary Syndrome (PCOS): Can lead to prolonged estrogen exposure without progesterone.

Diabetes: Diabetes is linked to a higher risk of endometrial cancer, partly due to associated obesity and insulin resistance.

History of Breast or Ovarian Cancer: Women with these cancers may have a higher risk of developing endometrial cancer.

Use of Tamoxifen: This breast cancer medication can increase endometrial cancer risk.

Radiation Therapy: Previous pelvic radiation therapy may increase the risk of endometrial cancer.

Risk Factors of Endometrial Cancer

  • Age (most common in women over 50)
  • Hormone imbalance (increased estrogen without progesterone)
  • Obesity
  • Diabetes
  • Early menstruation (before age 12) or late menopause (after age 55)
  • Never having been pregnant
  • Polycystic ovary syndrome (PCOS)
  • Family history, especially Lynch syndrome
  • Previous radiation therapy to the pelvis

Symptoms of Endometrial Cancer

  • Abnormal Vaginal Bleeding: This includes bleeding between periods, after menopause, or unusually heavy periods.
  • Pelvic Pain: Persistent pain or discomfort in the pelvic area can be a sign.
  • Pain During Intercourse: Some women may experience pain during sexual activity.
  • Unusual Vaginal Discharge: Watery or blood-tinged discharge that isn’t related to menstruation.
  • Unintentional Weight Loss: Losing weight without trying can sometimes be a symptom in advanced cases.
  • Fatigue: Feeling unusually tired or weak.

Diagnosis for Endometrial Cancer

  • Pelvic Exam: A physical examination to check for abnormalities in the uterus and surrounding areas.
  • Transvaginal Ultrasound: An imaging test that uses sound waves to create pictures of the uterus, helping to detect any abnormalities in the endometrium.
  • Endometrial Biopsy: A procedure where a small sample of the endometrial tissue is collected and examined for cancer cells.
  • Hysteroscopy: A thin, lighted tube is inserted through the vagina into the uterus, allowing the doctor to examine the endometrial lining visually.
  • Dilation and Curettage (D&C): A surgical procedure to collect a larger tissue sample from the uterus, often used if biopsy results are inconclusive.
  • Imaging Tests: CT scans, MRI, or PET scans may be used to assess the spread of cancer beyond the uterus.
  • Genetic Testing: Recommended if there is a family history of certain cancers to check for genetic syndromes like Lynch syndrome, which increases risk.

Treatments for Endometrial Cancer

  • Surgery: The most common treatment, usually involving a hysterectomy (removal of the uterus) and may include removing the ovaries, fallopian tubes, and nearby lymph nodes.
  • Radiation Therapy: High-energy radiation is used to target and kill cancer cells, often used after surgery or when surgery isn’t an option.
  • Hormone Therapy: Medications that block or lower estrogen levels can slow the growth of cancer, especially for advanced or recurrent cases.
  • Chemotherapy: Uses drugs to destroy cancer cells, generally recommended for advanced stages or if cancer has spread.
  • Targeted Therapy: Focuses on specific molecules involved in cancer growth, like HER2, providing a more personalized treatment approach for certain cases.
  • Immunotherapy: Boosts the body’s immune system to help it recognize and attack cancer cells, often used in advanced or recurrent cancers.
  • Palliative Care: Supportive care to manage symptoms and improve quality of life, often integrated alongside other treatments.

Preventive Measures for Endometrial Cancer

  • Maintain a Healthy Weight: Reducing excess body weight can help lower estrogen levels, which may decrease risk.
  • Follow a Balanced Diet: A diet rich in fruits, vegetables, and whole grains may reduce cancer risk.
  • Stay Physically Active: Regular exercise helps maintain hormonal balance and supports a healthy weight.
  • Use Birth Control Pills (if appropriate): Long-term use of birth control pills can reduce endometrial cancer risk but should be discussed with a doctor.
  • Manage Conditions like PCOS and Diabetes: Proper management of these conditions can reduce associated risks.
  • Limit Estrogen Therapy: For women using hormone replacement therapy (HRT), combining estrogen with progesterone can lower the risk of endometrial cancer.
  • Consider Risk-Reducing Surgery: For those with a high genetic risk, such as Lynch syndrome, preventive surgery may be an option.
  • Regular Gynecological Check-ups: Routine exams can help detect abnormal changes early on.

Frequently Asked Questions
Endometrial cancer, also known as uterine cancer, is a serious health concern affecting women worldwide. This type of cancer develops in the lining of the uterus, called the endometrium. While it may not receive as much attention as other forms of cancer, its impact on women's health should not be underestimated.
One of the primary causes of endometrial cancer is hormonal imbalance. Excessive levels of estrogen, a hormone responsible for regulating the menstrual cycle, can stimulate abnormal cell growth in the lining of the uterus. This hormonal imbalance can occur due to various reasons such as obesity, polycystic ovary syndrome (PCOS), or hormone replacement therapy (HRT) without progesterone.
Several key risk factors have been identified for endometrial cancer. One of the most significant is age, with the majority of cases occurring in women over the age of 50. Hormonal imbalances, such as an excess of estrogen relative to progesterone, also increase the likelihood of developing this type of cancer.
One of the primary symptoms of endometrial cancer is abnormal vaginal bleeding. This may include bleeding between periods, unusually heavy or prolonged menstrual periods, or post-menopausal bleeding. It's important to note that not all instances of abnormal bleeding indicate endometrial cancer, but it should be evaluated by a healthcare professional.
One common diagnostic procedure is a pelvic examination, where the healthcare provider examines the uterus, ovaries, and surrounding areas for any abnormalities or signs of cancer.
Surgery is often the primary treatment for endometrial cancer. It involves removing the uterus (hysterectomy) along with surrounding structures such as the fallopian tubes and ovaries. In some cases, nearby lymph nodes may also be removed for further evaluation.
One of the most effective ways to prevent endometrial cancer is through maintaining a healthy lifestyle. Regular exercise and maintaining a healthy weight can help lower the risk, as obesity is linked to an increased likelihood of developing this type of cancer. Additionally, eating a balanced diet that includes plenty of fruits and vegetables can provide the body with essential nutrients and antioxidants that may offer protection against cancer.
