The neurosurgeon makes an incision in the neck and performs this open surgical procedure to remove the tumor.

How fast do carotid body tumors grow?

They are slow-growing tumors that can remain asymptomatic for many years. The doubling time (TD) of carotid body tumors (CBTs), as estimated by Jansen et al using sequential imaging, was 7.13 years with a median growth rate of 0.83 mm/year.

Are carotid body tumors malignant?

Carotid body tumors (CBTs) are rare neoplasms of the carotid body. Most CBTs are benign; however, some can show malignant behavior. Malignant CBTs have an unpredictable history; often, there is no correlation between the histologic findings and the clinical behavior.

How common are carotid body tumors?

The incidence of carotid body tumors (CBTs) is less than 1 in 30000. CBTs represent more than half of neck paragangliomas (PGLs), yet still a very rare cause of neck lumps. Like other paragangliomas, CBTs originate from the neural crest. The most common site is the carotid body.
