Breast Clinic - fearing the worst

Hi All

I am new to these forums.   I recently found a hard lump on my left breast and a swollen node under my arm.  My GP referred me to the breast clinic and today I had a mammogram, ultrasound and core biopsy.   The mammogram was unclear but the ultrasound showed some cysts that were covering a lump which doesn’t have defined edges.   They said there is thickening around the nipple and it’s suspicious.   I have to wait two weeks.  The Dr said they will discuss as a team next moves and then contact me with another appointment.   I am swinging from feeling positive and then hopeless.   I have a history of anaemia and b12 deficiency so am worried physically I will struggle with treatment.   It just feels so overwhelming.  My Husband and kids have been amazing but I hate what the worry is doing to them.  I have a really stressful job and wonder how I’ll cope if it’s confirmed as bad news.   Anyway it’s good to vent and I hope to chat to some of you more.
