After radiation therapy, breast self-examination (BSE) should continue to be part of your routine. You will want to examine your breasts and your scar (if you had the lymph nodes removed) once a month to note any changes in the way they look or feel. Though you may have been doing BSE before your treatment, you will have to relearn what's considered "normal" for you now.
If you menstruate, the best time to do BSE is 2 or 3 days after your period ends, when your breasts are least likely to be tender or swollen. If you no longer menstruate, pick a day, such as the first day of the month, to do BSE.
