Clear cell endometrial cancer (endometrial CCC) is a rare type of womb cancer that can grow quickly. It typically affects people who have been through menopause.
There are several types of womb cancer, including endometrial cancer. The term “endometrium” describes the lining of the womb. Any cancer that originates in this lining is endometrial cancer.
Endometrial CCC is a rare type of endometrial cancer that originates in the cells of the lining of the womb. Under a microscope, endometrial CCC cells appear to be clear in color.
In this article, we will discuss the symptoms, causes, diagnosis, and treatment of endometrial CCC.

Endometrial CCC is a rare form of endometrial cancer that originates in the cells of the lining of the womb.
A 2023 review of a study from 2009 suggests that endometrial CCC represents fewer than
Endometrial cancer originates in the lining of the womb and comes in several forms.
There is currently no conclusive evidence to confirm the cause of endometrial CCC. However, a 2022 review of older studies suggests that several risk factors may lead to endometrial CCC, including:
- Age: Endometrial CCC is typically more common in females over the age of 60 years old.
- Menopause: Endometrial CCC is more common in people who have been through menopause.
- Obesity: Endometrial CCC may be more common in people with obesity.
- Hyperinsulinemia: This is when a person has too much insulin in their bloodstream.
- Ethnicity: People who are African American may be more likely to develop endometrial CCC.
- Genetics: People may inherit certain conditions or gene mutations that can put them at higher risk of developing endometrial CCC.
The current guidelines from the American College of Obstetricians and Gynecologists recommend that if a person experiences vaginal bleeding after menopause, a transvaginal ultrasound scan should be the first method to test for endometrial CCC.
However, a doctor may recommend further testing, as
A vaginal hysterectomy is a procedure in which a surgeon removes the womb and cervix through an incision in the vagina. A doctor can then test the womb, cervix, and lymph nodes for endometrial CCC cells.

Endometrial CCC is a stage 2 cancer, which means the cancer may be growing relatively quickly and may have spread to nearby lymph nodes. There is the potential for endometrial CCC to spread to other parts of the body, so treatment
- Total hysterectomy: This involves a surgeon removing the cervix and womb, which may eliminate endometrial CCC cells from the body.
- Extensive staging surgery: A surgeon may remove the ovaries, fallopian tubes, and nearby lymph nodes for evaluation to determine the severity of endometrial CCC and if the cancer may have spread.
- Chemotherapy and radiation therapy: These may help to shrink endometrial CCC cells if a person cannot have surgery. It may also help prevent endometrial CCC from reoccurring following surgery.

However, there may be a limit to the accuracy of these studies due to low numbers of participation. Experts need to conduct further research to give a more accurate outlook for a person with endometrial CCC.
A person should talk with a doctor about their individual situation and outlook. Many factors can affect the outlook of a condition.

What are the symptoms of endometrial CCC?
Endometrial CCC is a rare, aggressive form of womb cancer. It is more common in females over the age of 60 years old who have been through menopause.
Endometrial CCC may first present with vaginal bleeding after menopause. A person may also experience vaginal discharge, painful cramps, and prolonged periods.
Treatment for endometrial CCC typically includes surgery to remove the womb, cervix, other reproductive organs, and nearby lymph nodes. A person may also require chemotherapy or radiation therapy.
There is a limit to the amount of research into endometrial CCC, so it can be difficult to fully understand the causes, risk factors, and outlook for a person with endometrial CCC.
