Symptom 6: Stealthy Invader – Spread to Lymph Nodes
As we delve deeper into the symptoms of stage 4 thyroid cancer, we encounter signs indicative of the disease’s aggressive spread. A characteristic sign of this advanced stage is the cancer’s extension to nearby lymph nodes.
Lymph nodes are small, bean-shaped structures scattered throughout the body. They function as hubs for the body’s immune cells, crucial in fighting infections. However, their close connection to various bodily structures makes them a potential target for spreading cancer.
In the case of thyroid cancer, the disease can spread to lymph nodes in the neck. This spread can present as additional lumps or swellings in the neck, separate from the initial swelling at the thyroid gland. These lumps are usually firm and can move slightly when pressed.
Detecting lymph node involvement can be tricky, as the swellings may not be significant initially. However, with disease progression, these swollen nodes can become more prominent, adding to the discomfort and alarm. (6)
