A few weeks ago I felt a lump in my armpit.  I am terrified of doctors and hospitals so I have been watching it to see if it went down.  It  hasn’t  it has got bigger and I am now beside myself with worry.  I went to my doctors today and saw a nurse/practitioner .  Later I got a call from the breast clinic at my local hospital with an appointment for the 26 July.  I also have to  go back to the doctors for blood tests, the same day, she mentioned the word lymphoma, which has made me even more terrified.  Has anyone ever had a diagnosis of breast cancer , the only obvious sign being an enlarged armpit lymp node?  I cannot find anything on the internet.  To make matters worse tomorrow we go off on a dream holiday for a week.  I will not enjoy it, I cannot sleep or eat all I think about is the lump and find myself constantly feeling if it is still there.  I feel so bad for spoiling the holiday for my husband.  Any advice please.
