Brief description

The larynx is the upper part of the wind pipe and it includes the vocal cords. This SOP covers primary cancers arising in the larynx.

# non-SOP condition

Clinical onset

The most common presenting symptom is change in voice / persistent hoarseness.  Other symptoms include, cough, haemoptosis (coughing blood), and strider (noisy, high pitched breathing). The condition may also be found after investigation of palpable lymph nodes in the neck.

Clinical worsening

The only SOP worsening factor is for inability to obtain appropriate clinical management.  Appropriate management of the disease varies considerably with the type and stage of the disease and other factors.  A delay in obtaining treatment could lead to a worsening of the prognosis.
