4. Changes in Lymph Nodes
Lymph nodes are of keen significance in the body. These have an essential role in the body’s immunity. Their primary function is to boost up immunity through the process of filtering the body fluid and then remove the harmful cells. When any cancerous cell moves from the breast, then the first place where it travels is none other than the underarm. Lymph node resides in the underarm of the affected breast and leads towards the swelling over there.
The individual observing the lymph node in the underarm is more likely to experience it around collarbone as well. When it comes to the nature of these lymph nodes, then these seem to be tender, swollen, firm and small in appearance. Upon observing any such sign, you must seek medical aid by visiting the doctor.
