Sternum bump

I sometimes feel stupid for thinking too much about getting cancer again but I found a lump just under the area below where your collar bones meet on my chest. I hope that it is nothing.It is not sore ,well until I started checking it every half hour to see if it has gone away. I know it is new believe me I keep a check on myself because of my onco type score 12 to 15 . I It is about the size of the end of your thumb and I think it is attached .I can move my finger around it but I do not think it is moving. What do you all think?

Thanks. It is hard not to mess with it when you find it .I went to see a nurse prac.

friend of mine and she is sending me to a surgeon tomorrow. I think in my case they worry more because of my history. But I am strong as are my fellow survival sisters and I can deal with what ever comes my way cause God is Good all the time and He holds my hand day by day. I pray that all of you have Gods peace and Love .I always thought I would die on the spot if I were told I had cancer but I didn't and I am still here 4 years later .

Go for results tomorrow. I think they would have called if it were cancer . They thought it was fine after surgery. Thanks for the prayers and blessings of hope and strength wished for all my sisters
