Welcome, @kazzerq8. I moved your question about radiation side effects and reducing chances of recurrence to this existing discussion:
- What helped you make treatment decisions following DCIS lumpectomy? https://connect.mayoclinic.org/discussion/treatment-decision-following-dcis-lumpectomy/

I did this so you can read some of the previous posts and connect with other members like @m3rt @auntieoakley @simba2022 @windsurfer7 @catbuddy, who also had lumpectomy followed by radiation as treatment for DCIS.

Here's another discussion that you might find helpful too.
- Virtual support for Breast Cancer: Starting radiation soon https://connect.mayoclinic.org/discussion/virtual-support/

Kazzerqu8, how many radiation treatments have you had so far? How are you feeling?
