I am so sorry to hear about your cancer spreading before you found it. The Doctor who you went to that did not pursue the tests...Was he a surgeon, or a general practice man?
I had a lump under my arm smaller than a tennis ball, but bigger than a golf ball/, it was growing too, my elbow started to swollen up, I had painful lumps on my sternum, under the skin, and under my breast. It did not hurt, under the arm, When I was shaving I seen the lump. For 2 month I went to my doctor to tell something is wrong. He told me fatty tissue, fatty tissue, Fatty tissue. I told him, I have 2 armpits?! the other one is OK.
Finally he sent me for ultrasound - it was negative.
I asked him to do further workup, he denied.
I april, I went for my yearly mammogram/ by myself/, it was positive.
CAT scan, PET scan, surgery. Breast cancer metastatic to the liver, 10 lympnodes had cancer.
SO,MY SWOLLEN ARMPIT was not fatty tissue, it was CANCER.
Dear dolphingirl1224: There are many types of lumps, many of which are harmless. The important thing is to have this evaluated. Waiting one week is reasonable and you should not worry about having "let this go."
