Endometrial cancer

Hoping to find some support here. I'm not a cancer patient but I am a caregiver for my mother, who was diagnosed with Stag 3A Endometrial Cancer, an aggressive less common type, high grade uterine serous carcinoma. I didn't take my mother's cancer diagnosis really well. It's all very sad =(

Long story short, my mother, was experiencing irregular symptoms, post menopausal, and scheduled a visit with her primary care physician for checkup. This was in October 2021. Her physician didn't find any irregularities but just to be safe, ended up doing a endometrial biopsy. Shortly after, the results came back showing signs of a high grade uterine serous carcinoma. This broke my heart and I was devastated for her. She was then referring to the oncologist for further assessment.

We met with the gynecologists (end of Oct 2020) and the team immediately started the debunking/staging process which first, would involve surgery, a full hysterectomy. This was scheduled for early November. Everything happened so quick so from the first visit to the scheduled surgery, we had a week to take care of all the necessary lab works, pre-op, etc.

Initially, it was said they would perform a robotic assisted hysterectomy based on the initial lab report and scans. However, when they started the surgery, the noticed the tumor had spread more than what they initially suspected (or saw from scans) and performed a full open surgery. Surgery was a success, and the doctors were able to remove all visible cancer cells. Tumors did spread, but localized, within the tubes and ovaries, but nothing beyond that. No signs of tumor in nodes, etc. Final lab report based on the specimens removed and examined, staged the cancer as Stage 3A.

Post-Op, a month after, it was recommended that she consider chemo. She agreed and successfully completed six session of taxol/carbo and hercep. The treatment went well for her and she tolerated without any issues. She completed this end of March. I couldn't be more proud of her for fighting her way through this whole ordeal and being strong for both the surgery and the infusions.

Three months later, just recently, she went in for her three-month check up. CA-125 is elevated, but still within normal range, although still concerning as it jumped from the low teens to now 30. To be quite honest, I've been very paranoid and worried about her CA-125 level every time she gets her blood drawn. During her recent follow-up exam, her doctor noticed some tissue scarring, vaginal lesions, that she ended up taking some tissue sample to get it biopsied hoping ruling out recurrence. Although her doctor said not to worry about it, I am a bit concerned and now waiting for the final lab report is putting me unease. My mother doesn't know and I do not want to tell her at this point and worry her (English isn't her first language). I'm close to my mother and it breaks my heart to see her have to go through this, as anyone would with family members going through cancer.

Wanted to get some input to perhaps those who may have experience similar situations as above and may shed some light as to what the additional lesions may be. I fear that despite the surgery and the six chemo sessions, that this could be a recurrence, although, she has zero symptoms, and is as healthy as she can be. Just a bit sad as what this new discovery may be and I only fear the worst, but I'm hoping the final report comes back negative for any cancerous cells.

Sorry for the long story above. Just wanted to reach out to a community for support.
