Endometrial cancer – diagnosis and treatment
As we have mentioned in our previous article ‘Endometrial Cancer – Symptoms & Causes’, endometrial cancer is also called ‘Uterine cancer’. As the cells that make up the endometrial layer (inner lining of the uterus) change their nature and keep multiplying without a specific death time, results in endometrial cancer.
When you present yourself with the symptoms such as vaginal bleeding after menopause, bleeding in between periods, pain in lower abdominal region, your doctor will start with a series of questions followed by physical examination and then depending on the observations, he/she may ask for other tests such as biopsy, CT scan etc.
How is endometrial cancer diagnosed?
- Physical examination or pelvis examination.
Your gynecologist will insert gloved fingers of one hand into the vagina and press on the lower abdomen with the other to feel the ovaries and uterus. A speculum may be inserted into the vagina which opens it little wider and enables your doctor to see into the vagina.
- Transvaginal Ultrasound
A device called ‘transducer’ will be inserted into the vagina to get a picture of the interiors of the vagina, cervix and the uterus. The transducer emits ultrasound waves that are reflected by the walls of the uterus, cervix etc. The transducer captures the emitted sound waves and sends it to a computer like device which turns them into an image on the screen.
- Using a hysteroscope to see on the inside of the vagina and uterus
A device called hysteroscope (a thin tube with a camera and light at the end) will be inserted into the vagina. This is connected to a computer like device which pictures the camera input onto the screen so that your doctor can observe the internal organs better.

- Sampling of endometrial layer
If your gynecologist suspects the presence of something abnormal inside the uterus, a small sample of it will be taken and sent for biopsy. During biopsy, the tissue sample is observed under a microscope to look for the presence of cancer cells. Presence of cancer cells can confirm the presence of endometrial cancer or uterine cancer.
- Dilation and Curettage (D&C)
When it is not possible for your doctor to get a sample of the endometrial layer for biopsy, a minor procedure called ‘Dilation and Curettage’ is done to scrape the inner lining of the uterus. This layer is then sent for biopsy to look for the presence of cancer cells.
Once endometrial cancer is confirmed, staging of cancer is done on a scale of I to IV where I being the beginning stage wherein the cancer is localized to the uterus and hasn’t spread to any other closer tissues / organs of the body. Whereas, stage IV is when the cancer cells have passed through the surrounding tissues, entered the lymph nodes and spread and settled in other organs and start forming tumors there. This is called ‘metastasized’ stage of cancer. Depending on the stage of the cancer, treatment procedure will be decided.
Treatment of endometrial cancer
- Surgery
Surgery involves performing a hysterectomy procedure. Laparoscopic hysterectomy is the most preferred way of removing the uterus these days. Removal of uterus, fallopian tubes and ovaries (called Hysterectomy & Salpingo-oophorectomy) is performed leaving no chance of cancer cells to grow or spread.
Removing the uterus removes the ability to get pregnant forever and you will be informed about the same beforehand. If your gynecologist sees that the cancer has spread to the surrounding lymph nodes, they too will be removed.
- Radiation therapy
Radiation therapy involves focusing powerful energy beam onto the tumor or in the location of cancer cells. The energy in the radiation kills the cancer cells instantly. Radiation therapy may be done before a surgery or after a surgery to remove cancer tumors depending on the size. If the cancer tumor is large in size, radiation therapy helps in shrinking it and makes it easier to extract.
Radiation therapy can be performed using an external device that emits radiation or by using radioactive elements that are placed inside the vagina (internal devices). The internal device releases radioactive energy that kills the cancer cells.
- Chemotherapy
Chemotherapy involves injecting medicines through IV or orally into the body. The medicine kills the cancer cells and shrinks any tumor that might be present. Chemotherapy may be done in combination with radiation or surgery so that, any leftovers cancer cells will also be cleared up from the body.
- Hormone therapy
Reducing certain hormone levels can be detrimental to the growth of cancer cells. Hormone therapy targets in containing the hormone levels that support the cancer cell growth and as a result, the cells start dying sooner, shrinking the tumor. Hormone therapy is usually used in people in who the cancer is in an advanced stage.
- Targeted drug therapy
Exploiting the weakness of cancer cells with medicines is done via targeted drug therapy. Targeted drug therapy for endometrial cancer is usually combined with chemotherapy.
- Immunotherapy
Immunotherapy is a way of telling the immune system that the cancer cells are not one among the body cells but are harmful and the immune system needs to eliminate them. In order to escape from the immune system, the cancer cells produce a protein that blinds the immune system. The drugs used in immunotherapy prevents the cancer cells from producing the ‘protective’ protein, as a result the immune system takes charge and kills them. This is usually done as a last resort when none of the above mentioned procedures helped in eliminating cancer.
Conclusion
When you notice unusual bleeding, that can be with respect to the timing or with the amount of bleeding that’s happening during menstruation, do not delay in seeing a good gynecologist near you. Most of the times, the issue may be benign (non cancerous) but if it is cancer, the sooner the treatment starts, the easier and safer it would be to eliminate it from the body.
