Brain Tumors In Dogs Treatment
The treatment generally involves methods for getting rid of the tumor for good or slowing down the growth of the tumor.
Surgery becomes an option depending upon the nature of the tumor; its extent, location, size and severity.
However, for certain locations in the brain like that of the brainstem (the part of the brain continuous with the spinal cord and comprising the medulla oblongata, pons, midbrain and parts of the hypothalamus), surgery is not considered as it harbors the risk of causing death to the animal.
Radiotherapy is the most widely used and preferred treatment method for brain tumors in dogs.
It may be used as a lone treatment or in combination with other treatment methods.
The benefit of this method comes from the fact that the tumors will be eliminated without causing much harm to the normal tissues of the brain.
Chemotherapy is also available as a treatment for this condition in dogs.
However, the method yields successful results, only when the administered drugs have the ability to cross the blood brain barrier. Only high doses of medications are generally effective for treating the tumors, but again, such doses may be toxic for the normal brain tissues.
However, with medical advancement, many drugs have been evolved which can cross the blood brain barrier and help in getting rid of the tumor.
To conclude this piece on brain tumors in dogs, it is to be understood by all pet owners that their affected pets might not show any such signs or symptoms as mentioned above, until a few years.
This is due to the fact that the tumors have a slow growth rate and hence do not manifest themselves easily through any such signs.
