How can thyroid cancer cause wheezing? i read somewhere about it and i'm confused. i thought wheezing comes from the lungs.

Compressed trachea: In the late stages, before it actually strangles you, a neglected or inoperable thyroid cancer will cause narrowing of the trachea (windpipe). You'll hear the breathing sounds through the narrowed tube and if someone wishes to call this wheezing, it's just a minor error. If you have any concerns that you have thyroid cancer, please get seen. Best wishes.
