Why can a knot in the armpit also be an indication of breast cancer?

When a breast cancer begins to spread, first colonizations often occur along the draining lymphatic system. First station here are the lymph nodes in the armpit.

Sometimes a tumor in the chest is so small or so deep that it can not be palpated there, but it has already spread across the lymphatic system. Then the resulting knot in the armpit can be the first thing you can feel from the outside.

The lymph nodes are also called "guardian lymph nodes" because of their importance for breast cancer diagnostics.

But also important to know: Not every lump in the armpit means breast cancer. On the contrary. There are a number of other possible causes of knots in this area, many of them harmless in nature.
