I had surgery for breast cancer tumor removal and sentinal lymph node with cancer cells (and 3 other lymph nodes). This was 6 months ago, and the smell from the armpit in that side is horrid, totally different from the uneffected side. I am not sweating more, even when there is no sweat, the smell is sickly. I just wondered if anyone had any idea why this is, and if it is nornal.
