Hello. Four weeks ago my GP found a mass in my breast. He referred me on the suspected cancer pathway- expecting me to be seen within two weeks. I was given an appointment five weeks after I saw him- due to my hospital being overwhelmed. I am being seen net Tuesday. Obviously I'm very worried. The mass is noticeable and I've lost 8kg. My red blood cells are too big and I'm utterly exhausted. I would like to ask- my breast and under my armpit really aches. A dull ache and my breast feels full- as if I'm breastfeeding. Is this a sensation anyone else has?
