Due to the rich lymphatic vessels, rapid development, early lymph node metastasis, and poor prognosis.

(ii) Glottic type: Cancer limited to the vocal cords, more common in the front and middle sections, well differentiated, slow to develop, and less likely to metastasize due to the small number of lymphatic vessels. It can also spread upwards and downwards, and forwards and backwards.

(III) Subglottic type: Cancer located below the plane of the vocal cords. The cancer may spread forward to invade the thyroid gland and backward to the esophagus. This type of cancer develops faster than vocal cord cancer, but metastasizes more slowly than supraglottic cancer.
