Thank you for your query at DoctorSpring.com
I went through your reports. It seems your MRI is normal except for the mullerian cyst. You could meet surgeon for his opinion regarding biopsy or surgical removal. I personally do not think that as metastases. However, pathology report is the final one.
Regarding the sexual health, after radiation, vagina will appear to shrink and needs constant dilatation with estrogen cream application. I am not sure if ovaries were included in the radiation field over 25-30# fractions , in which case it would stop functioning. You can discuss this with your doctor, clarify your doubts again and talk to your future life partner.
Wishing you the best.
