The '''smaller''' the tumour is identification, the better the chance of successful removal and a '''good prognosis'''. As mentioned, these tumours are often locally invasive but '''slow to metastasise''', however the level of malignancy and therefore prognosis is often related to the '''location''' of the neoplasm. Those arising over the '''tonsil''' (squamous carcinoma of the tonsil or tonsillar carcinoma) are '''very malignant''', invading adjacent tissues and metastasising early. Squamous carcinomas of the '''tongue''' (especially in '''cats''') can also behave in a '''very malignant''' fashion. Those at more '''rostral''' sites, e.g. on the incisor gingivae, are '''less likely to metastasize''' early although they may be locally aggressive. They should be staged according to the '''World Health Organisation (WHO) system'''.
