Has anyone had vaginal brachytherapy because of one cancer cell in one lymph channel?

A MyEndometrialCancerTeam Member asked a question 💭
Brookville, IN

Recovering from a total hysterectomy after an endometrial cancer diagnosis. Dr. Said the lymph nodes did not map so they did not remove any nodes for a biopsy.. although there is one cancer cell hanging out in one lymph channel
Dr. Wants me to talk to a radiologist about vaginal brachytherapy. I am concerned because this might mean I will have to use a dilater possibly the rest of my life. Has anyone else had this kind of radiation for one cancer cell?

Why might vaginal brachytherapy be recommended for one cancer cell in a lymph channel?

Your doctor is likely recommending brachytherapy because cancer cells in lymph channels can be a risk factor for recurrence, even if lymph nodes weren't removed. Vaginal brachytherapy is commonly used after hysterectomy to target any remaining cancer cells and reduce the chance of cancer returning in the vaginal area, particularly the vaginal cuff where the uterus connected to the vagina.

Risk factors that may lead to brachytherapy recommendations include:
- Cancer spread to deeper tissue layers
- Cancer in lymph channels or nodes
- Higher grade cancers
- Age over 60

Even though it's just one cell detected, your medical team is being proactive about preventing recurrence. About dilator use and managing vaginal stenosis:

Vaginal dryness is the most common long-term side effect of vaginal brachytherapy. Vaginal stenosis (where the vagina becomes shorter and narrower) can occur if scar tissue forms, which can make intercourse more painful.

However, sexual side effects related to vaginal dryness and stenosis can be managed with proper support from your cancer care team. They can recommend specific treatments and approaches to minimize these effects.

It's worth having an open conversation with your radiation oncologist about your concerns regarding dilator use. They can discuss what preventive measures might help and whether dilators would definitely be necessary in your specific case.
