TUMOUR, INFLAMMATORY NEW GROWTH, ETC. 69 



in a dejected manner. Examination of the interior of the 

 mouth and throat with a speculum ma}- at this stage reveal 

 a red, angry-looking tumour growth on the gums, or a nasty 

 jagged ulcerating sore at the back of the fauces, close by the 

 tonsil. The left side seems to be the one most commonly 

 affected, although the right is by no means exempt. 

 External examination will now reveal a swollen condition 

 of the larynx and cervical glands on the affected side, a 

 state of affairs which may have escaped the owner's observa- 

 tion if the dog or cat is of the long-coated variety. 



Pressure upon either lesion causes pain, and the ulcer in 

 the mouth has on more than one occasion been diagnosed 

 and treated as due to an injury such as would be produced 

 by a bone or stick across the fauces (see Figs. 102 and 103). 

 If a small piece of the tumour can be excised and submitted 

 to an expert pathologist, the diagnosis can be speedily 

 verified. 



If humane counsels do. not prevail with the owner, the 

 patient gradually wastes away, and becomes a mere skeleton. 

 This latter remark applies ultimately to all cases of cancer, 

 whether the tumour is in the throat or some other region. 



If in the oesophagus or on the tongue (see Fig. 98), 

 the dysphagia is equally well marked, and the patient can 

 only swallow fluid foods. The cat whose oesophagus is photo- 

 graphed in Fig. 112 was kept alive for nearly three months 

 on milk alone. The case was exceptionally interesting, 

 partly because of the situation of the growth, and partly 

 because the history given when the patient was brought was 

 that it had a bone in the throat. 



The sarcomata are tumours growing from the connective 

 tissues. They do not so commonly affect the neighbouring 

 lymphatic glands as the carcinomata, but they are equally 

 as troublesome to deal with on grounds of malignancy, and 

 often attain an enormous size in the dog and cat. They 

 occur in almost all situations of the body, especially in the
