Decision Time - Need Advice

Thank you ladies for the feedback! Forgive me but I do not really know all my stats that well:

Stage 2, 4.5cm tumor in right breast, ER+ PR+, HER2+, they did a biopsy on one of my lymph nodes that they saw on my breast MRI back in December and that came out negative. They are doing surgery in August so we'll know then how many nodes are affected.
