In a patient with favorable risk pT1N0(mic/i+) breast cancer and favorable anatomy, would you use IMPORT-LOW style PBI while incorporating the high axilla?

For N0(i+), PBI is appropriate, I would not include axilla. 40/15, 30/5.

If N1mic, would not use PBI but would favor WBI, high tangents if ER+, RNI if ER-.

I would treat like node negative and IMPORT LOW without axilla or APBI like levy; both reasonable options.

I would prefer APBI as less exposure and thus less side effects in large breast size compared to IMPORT LOW.
