Lump in lymph node

[Henny]

Hi Jenny,
I also had a lump appear on the side of my cancer right in my armpit. It was about the size of an egg and would get larger and smaller. Turned out to be cording of the tendon. The tendon would just retract into a ball. I went to a medical masseuse who as able to work it out
The first year after diagnosis is by far the scarriest with every oddball thing being suspect. Hoping and praying for you to just have a simple easy explanation and it checks out to be nothing to worry about
