Hi Paula,
Your breast cancer is almost the same as mine only I didn't have clear margins so had further surgery a week later and I didn't have anypositive lymph nodes.
I ended up having four rounds of chemo, seven weeks of radium and now taking Tamoxifen for the next ten years (almost four years down).
I also had a drain in for a couple of weeks after second surgery and still ended up with a seroma which was always mentioned after mammogram and ultrasounds for a couple of years, assume it has gone as not mentioned anymore.
Googling is not always a good thing! can cause more stress!
Having someone with you when you see oncologist is good because they can ask questions that you may not think of at the time and they are able to reinforce what has been said after visit.
All the best on your next step, and we are always learning with this breast cancer!
Regards
Michelle
