Endometrial cancer: Symptoms, stage, treatment, and causes

What is Endometrial cancer

Endometrial cancer, also known as uterine cancer, is a type of cancer that originates in the endometrium, the inner lining of the uterus. The endometrium is the tissue that thickens and sheds during a woman’s menstrual cycle. Endometrial cancer occurs when abnormal cells within the endometrial tissue begin to grow and multiply uncontrollably. This can lead to the formation of a tumor in the uterus.

Endometrial cancer is the most common gynecologic cancer in women in the United States. It typically affects postmenopausal women, although it can also occur in younger women. The exact cause of endometrial cancer is not always clear, but several risk factors, including hormonal imbalances, obesity, and a history of certain conditions like endometrial hyperplasia, may increase the likelihood of developing this cancer.

Common symptoms of endometrial cancer include abnormal vaginal bleeding, such as bleeding between periods or after menopause, pelvic pain, and a feeling of fullness in the pelvis. Early detection and treatment are crucial for a positive prognosis, and treatment options often include surgery, radiation therapy, chemotherapy, and hormone therapy, depending on the stage and type of cancer.

If you suspect you may have endometrial cancer or have any concerning symptoms, it’s essential to seek medical attention promptly for a thorough evaluation and diagnosis by a healthcare professional.

What are the symptoms of endometrial cancer?

Endometrial cancer, also known as uterine cancer, often presents with the following symptoms. It’s important to note that these symptoms can also be caused by various other non-cancerous conditions, but if you experience any of these symptoms, it’s essential to consult a healthcare professional for a proper evaluation and diagnosis:

Abnormal Vaginal Bleeding

  • Postmenopausal bleeding: Vaginal bleeding or spotting that occurs after menopause.
  • Irregular menstrual bleeding: Unusually heavy or prolonged periods or irregular bleeding between periods.

Pelvic Pain

  • Pelvic pain that is not associated with menstruation or other gynecological conditions.

Painful Intercourse

  • Pain or discomfort during sexual intercourse.

Pelvic Pain or Pressure

  • A feeling of fullness or pressure in the lower abdomen or pelvis.

Unintended Weight Loss

  • Unexplained weight loss without changes in diet or exercise.

It’s important to recognize that these symptoms can vary in severity and may not always be present. Additionally, other conditions, such as fibroids or hormonal imbalances, can cause similar symptoms. If you or someone you know experiences any of these symptoms, it’s crucial to seek medical attention for a proper diagnosis. Early detection and treatment can improve the prognosis for endometrial cancer. Your healthcare provider may perform a physical examination, imaging tests, and may recommend a biopsy to confirm the diagnosis.

What causes endometrial cancer?

Here are some of the factors associated with an increased risk of developing endometrial cancer:

Hormonal Imbalance: The most significant risk factor for endometrial cancer is an excess of the hormone estrogen relative to progesterone in the body. This hormonal imbalance can stimulate the endometrial cells to grow and divide, potentially leading to cancer.

Age: Endometrial cancer is more common in postmenopausal women, with the majority of cases occurring in women over the age of 50.

Obesity: Excess body fat can lead to increased production of estrogen in the body, which can raise the risk of endometrial cancer.

Endometrial Hyperplasia: This is a precancerous condition where the lining of the uterus becomes thicker, and it can progress to endometrial cancer in some cases.

Polycystic Ovary Syndrome (PCOS): Women with PCOS often have higher levels of estrogen and lower levels of progesterone, which can increase their risk of endometrial cancer.

Estrogen Replacement Therapy: Long-term use of estrogen-only hormone replacement therapy (HRT) without a progestin in postmenopausal women can increase the risk of endometrial cancer.

Tamoxifen: This medication, commonly used for breast cancer treatment and prevention, has been associated with a slightly increased risk of endometrial cancer.

Hereditary Factors: Some inherited genetic syndromes, such as Lynch syndrome (hereditary nonpolyposis colorectal cancer or HNPCC), can increase the risk of endometrial cancer.

Diabetes: Women with diabetes, particularly type 2 diabetes, may have a higher risk of endometrial cancer due to insulin resistance and elevated insulin levels, which can stimulate the growth of endometrial cells.

Nulliparity: Women who have never been pregnant (nulliparous) have a slightly increased risk of endometrial cancer.

Personal History of Breast or Ovarian Cancer: A history of certain other cancers can be associated with an increased risk of endometrial cancer.

Diet and Lifestyle: A diet high in saturated fats, low in fruits and vegetables, and lack of physical activity can contribute to obesity and, consequently, a higher risk of endometrial cancer.

Endometrial cancer, also known as uterine cancer, is a type of cancer that begins in the lining of the uterus (the endometrium). Several risk factors are associated with an increased likelihood of developing endometrial cancer. It’s important to note that having one or more of these risk factors does not mean you will definitely develop the disease, but they may increase your risk. The primary risk factors for endometrial cancer include:

What are the risk factors for endometrial cancer?

Age: The risk of endometrial cancer increases with age, with most cases occurring in women over 50. It is relatively rare in women under 40.

Obesity: Being overweight or obese is one of the most significant risk factors for endometrial cancer. Excess body fat can lead to an imbalance of hormones, particularly estrogen, which can promote the growth of endometrial cells.

Hormone Replacement Therapy (HRT): Long-term use of estrogen-only hormone replacement therapy (HRT) without progesterone in postmenopausal women is associated with an increased risk of endometrial cancer. Combining estrogen with progesterone reduces this risk.

Menstrual history: Women who started menstruating at an early age or experienced late menopause have a longer lifetime exposure to estrogen, which can increase the risk of endometrial cancer.

Polycystic Ovary Syndrome (PCOS): PCOS is a condition that can lead to hormonal imbalances, including high levels of estrogen, which may increase the risk of endometrial cancer.

Endometrial hyperplasia: This is a condition in which there is an overgrowth of cells in the lining of the uterus. It can be a precursor to endometrial cancer if left untreated.

Diabetes: Women with type 2 diabetes have a higher risk of developing endometrial cancer, possibly due to the link between insulin resistance and higher estrogen levels.

Family history: A family history of endometrial cancer or certain hereditary conditions, such as Lynch syndrome, can increase the risk.

Personal history of breast or ovarian cancer: Women who have had breast or ovarian cancer may have a higher risk of endometrial cancer, especially if they were treated with estrogen-only HRT.

Tamoxifen use: Tamoxifen is a medication used to treat breast cancer. It may increase the risk of endometrial cancer, particularly in women who have taken it for an extended period.

Never having been pregnant (nulliparity): Women who have never been pregnant may have a slightly higher risk of endometrial cancer.

Certain genetic mutations: Inherited genetic mutations, such as those associated with Lynch syndrome, can increase the risk of endometrial cancer.

What are the stages of endometrial cancer?

Endometrial cancer, also known as uterine cancer, typically develops in the lining of the uterus (the endometrium). The stages of endometrial cancer are determined based on the extent of the cancer’s spread. The most commonly used system for staging endometrial cancer is the FIGO (International Federation of Gynecology and Obstetrics) staging system, which includes the following stages:

Stage 0 (Tis): This is carcinoma in situ or endometrial intraepithelial neoplasia. Cancer cells are found only in the innermost lining of the uterus (endometrium) and have not invaded the myometrium (the muscular layer of the uterus) or other nearby tissues.

Stage I: Cancer is limited to the uterus.

  • Stage IA: Cancer is found only in the endometrium.
  • Stage IB: Cancer has invaded the inner half of the myometrium.

Stage II: Cancer has invaded the cervix but has not spread beyond the uterus.

  • Stage IIA: Cancer involves the endocervical glandular cells.
  • Stage IIB: Cancer has spread to the cervical stroma (connective tissue of the cervix).

Stage III: Cancer has spread beyond the uterus, but it is still confined to the pelvis.

  • Stage IIIA: Cancer has spread to the serosa (outer layer) of the uterus or the fallopian tubes and ovaries.
  • Stage IIIB: Cancer has invaded the vagina.
  • Stage IIIC: Cancer may have spread to nearby lymph nodes, the pelvic and/or para-aortic lymph nodes.

Stage IV: Cancer has spread to distant organs or tissues.

  • Stage IVA: Cancer has spread to the bladder or rectum.
  • Stage IVB: Cancer has spread to distant organs, such as the lungs, liver, bones, or other organs.

What are the different types of endometrial cancer?

Endometrial cancer, also known as uterine cancer, typically arises from the inner lining of the uterus (the endometrium). There are several different types of endometrial cancer, with the most common being endometrioid adenocarcinoma. The different types of endometrial cancer are categorized based on their histological features and may have distinct characteristics, prognosis, and treatment approaches. The main types include:

Endometrioid Adenocarcinoma

This is the most common type, accounting for approximately 80-90% of all endometrial cancers. It is often linked to an excess of estrogen and typically occurs in postmenopausal women. It tends to have a relatively good prognosis when detected early.

Serous Carcinoma

Serous carcinoma is a more aggressive form of endometrial cancer and is less common than endometrioid adenocarcinoma. It tends to occur in older women and is more likely to invade the myometrium (the muscular layer of the uterus). It has a poorer prognosis than endometrioid adenocarcinoma.

Clear Cell Carcinoma

Clear cell carcinoma is a rare type of endometrial cancer, accounting for about 2-5% of cases. It is often associated with a poorer prognosis and tends to occur in postmenopausal women.

Mucinous Adenocarcinoma

Mucinous adenocarcinoma is also a less common type of endometrial cancer, accounting for about 1-9% of cases. It is characterized by the presence of mucin-producing cells.

Mixed Carcinomas

These are tumors that contain a mixture of different cell types, such as a combination of endometrioid and serous components.

Undifferentiated Carcinoma

This type is characterized by poorly differentiated cells, making it more aggressive and challenging to treat.

What are the treatments for endometrial cancer?

The treatment for endometrial cancer, also known as uterine cancer, depends on several factors, including the stage of the cancer, the grade of the tumor, the patient’s overall health, and their preferences. Treatment options for endometrial cancer typically include one or a combination of the following:

Surgery: Surgery is often the primary treatment for endometrial cancer. The main surgical options include:

  • Hysterectomy: This involves the removal of the uterus and may include the removal of the fallopian tubes and ovaries as well (bilateral salpingo-oophorectomy).
  • Lymphadenectomy: Sometimes, nearby lymph nodes are also removed to determine if the cancer has spread.
  • Lymph node sampling: In some cases, only a few lymph nodes are removed and examined for cancer cells.

Radiation therapy: Radiation therapy uses high-energy X-rays to target and kill cancer cells. It may be used before surgery to shrink the tumor, after surgery to kill any remaining cancer cells, or as the primary treatment for certain cases.

Chemotherapy: Chemotherapy involves the use of drugs to kill cancer cells or stop their growth. It is typically used for advanced or aggressive endometrial cancer or when the cancer has spread to other parts of the body.

Hormone therapy: Hormone therapy may be used for certain types of endometrial cancer that are hormone-sensitive. This therapy may involve medications that block the effects of estrogen or reduce the amount of estrogen in the body.

Targeted therapy: Targeted therapy drugs are designed to target specific molecules or pathways involved in cancer growth. Some of these drugs may be used for advanced or recurrent endometrial cancer.

Immunotherapy: Immunotherapy is a relatively newer treatment approach for some cases of endometrial cancer. It works by boosting the body’s immune system to help it recognize and attack cancer cells.

How can you lower your risk of endometrial cancer?

Lowering your risk of endometrial cancer involves making certain lifestyle choices and managing risk factors. Endometrial cancer is the most common gynecologic cancer in women, and while some risk factors like genetics and age are beyond your control, there are steps you can take to reduce your risk:

Maintain a Healthy Weight

Being overweight or obese is one of the most significant risk factors for endometrial cancer. Fat cells can produce excess estrogen, which is linked to an increased risk of this cancer. Maintaining a healthy weight through a balanced diet and regular physical activity can help reduce your risk.

Physical Activity

Regular exercise can help control weight and lower the risk of endometrial cancer. Aim for at least 150 minutes of moderate-intensity exercise or 75 minutes of vigorous-intensity exercise per week.

Healthy Diet

A diet rich in fruits, vegetables, whole grains, and low in saturated fats can contribute to overall health and may lower the risk of endometrial cancer. Additionally, a diet high in fiber can help regulate hormones.

Hormone Therapy

Avoid long-term use of hormone replacement therapy (HRT), particularly estrogen-only HRT without progestin. If you need HRT, discuss the lowest effective dose and duration with your healthcare provider.

Birth Control

Oral contraceptives (birth control pills) have been shown to reduce the risk of endometrial cancer. However, consult your healthcare provider before starting or changing any medication.

Pregnancy and Breastfeeding

Pregnancy and breastfeeding can have a protective effect against endometrial cancer. The more pregnancies you have and the longer you breastfeed, the greater the protective effect may be.

Manage Diabetes

If you have diabetes, managing your blood sugar levels effectively can help reduce the risk of endometrial cancer. Consult with your healthcare provider to create a diabetes management plan.

Regular Check-ups

Early detection can be key to successful treatment. Regular gynecological check-ups and discussions with your healthcare provider about risk factors and symptoms are important.

Genetic Counseling

If you have a family history of endometrial or other related cancers, consider genetic counseling to assess your risk and discuss preventive measures.

Avoid Smoking

Smoking is linked to various types of cancer, including endometrial cancer. Quitting smoking can reduce your risk and improve overall health.

Limit Alcohol Consumption

Excessive alcohol consumption may increase the risk of endometrial cancer. If you choose to drink, do so in moderation (up to one drink per day for women).

The Bottom Line

“Early detection and timely medical intervention are crucial for managing endometrial cancer effectively, emphasizing the importance of regular screenings and awareness.”
