how big is a auxillary lymphnode, under the arm?

Answer 1

AXILLARY as in axilla which means "armpit" , not auxiliary that means secondary or complementing or additional etc

Normally they are not palpable , they are that small and covered by tissue .

Any infectious or malignant problem affecting the ARM or BREAST might cause an enlargement of the axilary lymph nodes on the same side .

In such conditions the lymph nodes in addition to swelling up , they might become painful to touch , hard , and many lymph nodes might appear as if they have fused together .

Hydradenitis Suppurativa is a severe infection of the lymph nodes in the axillla , where the lymph glands become swolen with PUS and ultimately open onto the skin and excrete the pus causing pain and disfigurement . Frequently surgery is needed to control the disease by removing the lymph glands .

Answer 2

Although sometimes refered to as large lymph nodes, this is a relative term.

A normal axillary lymph node is smaller than a pea.

With breast cancer, sometimes a single node (sentinal node ) is removed, sometimes a group of nodes and sometimes none.

In my case I had 16 removed and cancerous cells were found in 3 of these.

Answer 3

Depends on if it's normal or not. I had one the size of a golf ball, and had 11 total removed.

Answer 4

Normally, you wouldn't even be able to feel yoru axillary lymph nodes. If they are swollen and you can feel them, please get them checked out by a physician.
