So sorry that you are facing this too. If they took 3 nodes and these were all clear then it is unlikely that the cancer skipped these nodes and went into others further along.
Lymphedema is one of the things that still needs research for better answers. It effects some people who only have a couple of nodes taken and yet others who have 30 nodes removed never have a problem! It is very scarey but treatable if you get onto it early. Do you have someone you are seeing for treatment of this?
I had 6 rounds of chemo (3x FEC, 3x Docetaxel) over 18 weeks, then 25 radiotherapy treatments. You will feel better once you start treatment because you will feel like things are progressing. There are lots of bloggs about chemo and what people have found helpful on here. But if you have specific concerns just post about them and there will be someone who can help. This is the best place for support. Wishing you all the best. Take care.
