Worried, please help

This is my first post in a very long time.  Six years ago I was dianosed with breast cancer, I had surgery, chemo and radiation.  I had a follow-up with my doctor and a mamogram just two months ago and everything was fine, they did note that my breasts were "very dense".

Today, I was taking a shower and I noticed that my breast looks black and blue in spots and going down my side.  It's Saturday and I called the doctor and got directed to his on call doctor who told me to wait until Monday, if this does not look like it's clearing I will need to come in and have the doctor look at it. 

I am so worried.. could this be IBC?  Is it possible to have breast cancer and then be dianosed with another type of breast cancer like IBC?  The only symptom I have is this black and blue (which looks like pictures I have found on the internet), I have no other symtoms.

I'm so scared,

Thank you for asking.  I called the doctor and expected to be told to come in.  Instead I was called by his assistant, she said that she thinks I some how "brused" my breast.  She said that breast cancer does not present like this.  She wants me to call in two weeks and let her know if it is gone.  It's now I week later and it's not any worse and it is not has red but it is purple.  It's not in one spot.  It is along the scar line on the top and down the side of my breast.  I am so scared.  My first cancer was ER positive, with one node positive and close but clear margins.
