How Fast Does Endometrial Cancer Spread? What You Should Know

How quickly endometrial cancer progresses largely depends on its type and grade. Most cases are type 1, which tends to grow slowly and is often caught early, when it’s still confined to the uterus. Type 2 cancers, which are less common, tend to grow and spread more quickly.

Those details come from the biopsy and scans your care team uses to work out the stage. Here’s what affects how endometrial cancer progresses, where it may spread to, and how staging shapes the treatment plan.

How fast does endometrial cancer spread?

The speed at which endometrial cancer grows and spreads may vary in each case. Some of them tend to grow slowly over months or years, while others could be more aggressive and spread more quickly. The cancer type, grade, and stage at diagnosis may all influence how quickly endometrial cancer may progress.

In many cases, endometrial cancer is diagnosed while it is still confined to the uterus, when treatment is generally more manageable. However, cancer cells could spread beyond the uterus if the disease progresses. This spread, known as metastasis, may involve nearby tissues and lymph nodes before reaching more distant organs.

What factors affect how fast endometrial cancer spreads?

Endometrial cancer does not spread at the same rate in every case, and there is no fixed timeline for how quickly it may progress. The type and grade of the cancer are important factors that may affect how aggressive it is and how likely it is to spread beyond the uterus.

Types of endometrial cancer

Endometrial cancer has different subtypes that could behave differently. Traditionally, they have been broadly described as type 1 and type 2.

• Type 1 cancers: which are usually low‑grade endometrioid tumours, tend to grow more slowly and often develop over several months or years. 

• Type 2 cancers: such as papillary serous carcinoma and clear cell carcinoma, are less common but more aggressive. They spread faster beyond the uterus and into lymph nodes or distant organs.

Grade of endometrial cancer

Endometrial cancer is also assigned a grade by the International Federation of Gynecology and Obstetrics (FIGO) based on how abnormal the cancer cells look under a microscope and how quickly they are likely to grow.

• Grade 1: means that the cancer cells closely resemble healthy endometrial cells. They grow slowly and are less likely to spread.

• Grade 2: shows that the cells look slightly more abnormal and grow moderately faster.

• Grade 3: indicates that the cells appear highly abnormal, grow more quickly and are more likely to spread.

If you are unsure about your tumour grade or cancer type, schedule an appointment with Thomson Women's Clinic & Cancer Surgery. A gynaecological oncologist could provide you with more detailed information to help you make a more informed decision about your care.

Where does endometrial cancer spread?

Endometrial cancer usually spreads within the uterus first and then to nearby areas such as the cervix, ovaries, fallopian tubes, and pelvic lymph nodes before reaching more distant parts of the body. As the cancer grows, it can extend deeper into the muscular layer of the uterus (the myometrium) and then spread to nearby tissues, lymph nodes, or distant organs. 

The extent of this spread is reflected in endometrial cancer’s staging system. A higher stage indicates that the cancer has spread further from where it first developed.

How does endometrial cancer spread at each stage?

• Stage 1:
  • The cancer is confined to the uterus and has not spread to nearby lymph nodes or distant organs. It may be limited to the endometrium, the inner uterine lining of the uterus, or may have grown deeper into the myometrium, the muscular layer of the uterus.
• Stage 2:
  • The cancer has spread from the uterus into the connective tissue of the cervix, known as the cervical stroma, but remains within the uterus and cervix.
• Stage 3:
  • The cancer has spread beyond the uterus but remains in nearby areas of the pelvis or abdomen. It may affect the ovaries, fallopian tubes, vagina, surrounding tissues, or nearby lymph nodes.
• Stage 4:
  • The cancer has spread beyond the pelvic region. It may affect nearby organs such as the bladder, bowel, or more distant parts of the body, including the lungs, liver, or bones, as well as distant lymph nodes.

What are the signs that endometrial cancer has spread?

The symptoms of metastasised endometrial cancer may vary depending on how far the cancer has grown and which parts of the pelvis or body are affected. 

When cancer is still near the uterus

When the cancer is still in or near the uterus, you may notice:

• Abnormal vaginal bleeding (including bleeding between periods, heavier-than-usual periods, or any bleeding after menopause).

• Unusual or unpleasant‑smelling vaginal discharge.

• Persistent pelvic pain or pressure.

• Pain during urination or intercourse.

• Unexplained weight loss, persistent tiredness, or loss of appetite.

When cancer has spread to distant organs

If endometrial cancer spreads to more distant organs, you may develop symptoms related to the area involved:

• Bladder or bowel:

  • Blood in the urine, pain or difficulty when urinating, changes in bowel habits, or blood in the stool.

• Liver: 

  • Pain in the upper right side of the abdomen, loss of appetite, abdominal swelling, or jaundice (yellowing of the skin and eyes).

• Lungs:

  • Persistent cough, shortness of breath, chest pain, or coughing up blood.

• Bones:

  • Persistent pain in your back, hips or ribs that often lingers at night or when you are resting.

• Brain:

  • Headaches, dizziness, balance problems, seizures, or changes in speech or memory.

How is endometrial cancer spread diagnosed?

If your doctor suspects that endometrial cancer has spread, they may use a combination of imaging tests, laboratory tests, and biopsies to assess the extent of the disease. These tests may help your specialist determine whether the cancer has spread beyond the uterus and identify which areas of the body may be affected. 

Common diagnostic tests may include:

• Ultrasound:

  • Often one of the first imaging tests used to assess the uterus and look for abnormalities in the endometrium.

• CT scan:

  • A CT scan uses a series of X-ray images to create detailed pictures of the chest, abdomen, and pelvis, helping doctors look for signs of cancer in nearby or distant organs.

• MRI scan:

  • An MRI scan uses strong magnetic fields and radio waves to produce detailed images of the uterus and surrounding tissues. It could help assess how deeply the cancer has grown into the uterine muscle and whether nearby tissues are affected.

• PET scan:

  • A PET scan uses a small amount of radioactive glucose to identify areas of increased activity that may indicate cancer cells. It may be used to look for cancer that has spread to other parts of the body.

• Blood tests:

  • These may be used to assess your general health and check how well your liver and kidneys are functioning. Your doctor may also recommend a CA-125 blood test in certain situations, although this marker alone cannot confirm whether endometrial cancer has spread.

• Biopsy:

  • If imaging identifies a suspicious area, your doctor may take a small tissue sample for examination under a microscope. A pathologist then could determine whether cancer cells are present.

How is endometrial cancer that has spread treated?

Treatment for endometrial cancer that has spread depends on the areas affected, its type and grade, your overall health, and how well you are likely to respond to treatment. Your specialist may recommend a combination of surgical and non-surgical treatments to control the cancer, slow its growth, relieve symptoms, and improve your quality of life.

Surgical treatment

The most common procedure is a hysterectomy, which involves removing the uterus and cervix. Surgery may still be considered if the cancer could be safely removed. Depending on the extent of the cancer, the ovaries, fallopian tubes, nearby lymph nodes, or surrounding tissues may also be removed to reduce the risk of the cancer spreading or recurring.

Non-surgical treatments

If surgery is not suitable or additional treatment is needed, your specialist may recommend one or more of the following:

• Radiotherapy: which uses high-energy radiation to destroy cancer cells or reduce the risk of recurrence.

• Chemotherapy: which uses anti-cancer medicines to destroy cancer cells that may have spread beyond the uterus.

• Hormone therapy: which may be suitable for certain hormone-sensitive endometrial cancers or for women wishing to preserve fertility.

• Immunotherapy: which helps the body's immune system recognise and attack cancer cells. This treatment is usually considered for women whose endometrial cancer is linked to Lynch syndrome, as these specific hereditary tumours tend to respond well to immunotherapy drugs.

• Targeted therapy: which uses medicines that specifically target certain genetic or molecular changes within cancer cells.

If you are unsure which treatment may be suitable for your condition, consult with a specialist to help you make a more informed decision about your care. Schedule an appointment with Thomson Women's Clinic & Cancer Surgery for a consultation with a gynaecological oncologist.
