Some of the possible causes of a tumor in a dog's mouth or on the jaw include the following: Osteosarcoma: This can be external, just on the jaw bone, and not involve the mouth at all.
The drug is understood to damage multiple regions of the cochlea, causing the death of outer hair cells, as well as damage to the spiral ganglion neurons and cells of the stria vascularis. [27] Long-term retention of cisplatin in the cochlea may contribute to the drug's cochleotoxic potential. [28]

A 10-year-old female beagle with oral cancer. Cancer is the leading cause of death in dogs. [1] It is estimated that 1 in 3 domestic dogs will develop cancer, which is the same incidence of cancer among humans. [2] Dogs can develop a variety of cancers and most are very similar to those found in humans.
Mammalian cochlear hair cells are of two anatomically and functionally distinct types, known as outer, and inner hair cells. Damage to these hair cells results in decreased hearing sensitivity, and because the inner ear hair cells cannot regenerate, this damage is permanent. [4] Damage to hair cells can cause damage to the vestibular system and ...
They are thought to damage the hair cells of the cochlea. Long-term exposure to these drugs may cause damage that progresses to the upper turn of the cochlea, impairing hearing or even causing deafness. [6] Glycopeptides, on the other hand, are rarely associated with ototoxicity.
Proliferating supporting cells can acquire hair cell fate in mitotic division. The mouse's neonatal supporting cells proliferate after hair cell death and regenerate hair cells after damage. [26] The neonatal cochlea is resistant to hair cell damage caused by exposure to noise or drugs, which are toxic to the cochlea, or auditory nerve, in vivo ...
Sensory hearing loss often occurs as a consequence of damaged or deficient cochlear hair cells. [disputed – discuss] Hair cells may be abnormal at birth or damaged during the lifetime of an individual. There are both external causes of damage, including infection, and ototoxic drugs, as well as intrinsic causes, including genetic mutations.
