First bilateral IDC, now SCC

I was diagnosed with bilateral breast cancer in Aug 2012.  I finished my last round of chemo on Dec 10, 2012.  Less then two weeks later a bump appears on my chin.  I really thought it was just a blind pimple that was going to heal slowly due to my immune system being down from the chemo.  It stayed  the same for weeks then one day it just took off and started to spread across my chin.  It was red, swollen and very painful.  It also started to get a crusty appearence to it. 

I go to the deramtologist on Feb 18, 2013. (I inform them of my recent cancer and treatment) They do a biopsy for infection, give me a script for some acne cream and tell me to come back in a week.  I go back on Feb 25, 2013 and am told it isn't a fungal infection.  They tell me to stop using the acne cream since it doesn't appear to be doing any good and then give me a script for an antibiotic (used for severe acne) and a steriod cream.  They then tell me to come back in two weeks but on a Thursday instead.  The NP wants me to see the other deramtologist in the office. Now during this two and a half week wait, it spreads to my lower lip, the speriod cream is making it itch worse then before and I stop using it.  I see my Oncologist on March 11, 2013.  My three month since chemo completion visit, and to start my tamoxifen treatment.  I tell her about my deramtolgy visits.  I tell her I am to go back in three days to see another doctor.  She doesn't want to start the tamoxifen until we know whats going on with my chin and lip. I am to call her asap after my appt on the 14th.  She wants me to go to the nearby University hospital.

So I go back on Mar 14, 2013, the new doctor I see takes one look at me and says " due to your previous cancer and chemo, I am concerned this is a new cancer brewing".  He does another biopsy, this time on my lip.  He tells me to come back in a week.  I call my oncologist and she tells me to lets see what this biopsy says and when I get the results if the deramtologist doesn't send me to the Unversity hospital, she will.  I go back on March 21, 2013 and he tells me it is SCC and where he has seen plenty of that, he has never seen anything like mine.  Not really what you want to hear.  He then says I need to go to make an appt with University hospital head and neck dept.  My head was spinning, really cancer?  I had been going there for over a month and being treated for acne!  During that month it was getting worse.  I am just so frustrated.  They should have biopsied it for cancer on my intial visit.  Two cancer diagnosis in seven months.....I have done some research, SCC can be very hard to beat.

So that was four days ago, I am now waiting for the University to gather all my medical records and call me back with an appointment.  This SCC covers most of my chin and bottom lip.  I'm really frightened, I could use some input, surely I am not alone.  Thanks in advance:)
