Cancer represents a unique state whereby the body's healing system fails to eliminate cells with damaged or altered DNA.
This allows these cells to escape the normal regulatory signals leading to uncontrolled cell growth. While most auto-immune diseases represent a failure of the healing system from an over-active immune system, cancer represents the extreme opposite, whereby the immune system is hypoactive (at least in regard to the tumor). On the other hand, both chronic immune diseases and cancer probably represent outcomes from the failure of the healing system brought about by living within a polluted environment, coupled with the genetic make-up of the dog.
While we are beginning to unravel the complex biochemistry of cancer development and have begun to understand how DNA is damaged and repaired, we still have a long way to go before the cure for cancer will be found. Spontaneous healing of cancer has been documented many times in human beings and animals, suggesting that a cure is possible. On the other hand, there is a great deal of information about the potential for preventing many forms of cancer. Most of these techniques involve the use of diet and dietary supplements. We can not control the air we breath, unless we do this as a whole. Using alternative means of transportation, car-pooling and clean energy production are good for the environment and for those living in it. It does pay to fool Mother Nature, she will get even in the end. We can, however, control the food our pets eat and the water they drink; thereby, reducing their pollution load. We can provide our pets with anti-oxidants and bioflavonoids, compounds which help protect DNA and the healing system. We can give them sufficient fiber in there diets to support digestion and protect the gi tract from cellular damage.
Treatment of cancer with traditional Western medicine involves surgery (to remove or de-bulk the tumor mass), ionizing radiation (to expose the tumor to lethal doses radiation, minimizing radiation exposure to surrounding healthy tissue), and chemotherapy (to poison the rapidly growing cancer cells without poisoning the rest of the body). One or all of these methods may be employed in a given patient in an attempt to delay or prevent further cancer growth. On average, the success of Western approaches to cancer provides 1 to 18 months of relief from the cancer. While longer survival times are seen with certain forms of cancer, the long term prognosis for even the best forms of "systemic" cancer is poor to grave. The best chance for a good prognosis is for localized cancer (particularly benign lesions) which can be removed completely with surgery. When surgical removal of the cancer is not possible, or when the cancer has already spread to other organs (metastasized), control of the tumor may not be possible by conventional means and the owner must make difficult choices about the continued care of their pet. Some of these choices are very expensive. Traditional Western diagnostic methods have advanced dramatically in the last few years and provide the best chance to discover the natural of the tumor and to predict its clinical course. Advanced imaging techniques like diagnostic ultrasound, computer-assisted tomography (CAT scans) and magnetic resonance image (MRI scans) have vastly improve tumor diagnosis. Fine-needle aspirates or "true-cut" biopsies of tumors (sometimes performed in conjunction with an imaging technique) can provide cytological confirmation or histological diagnosis of the tumor type, leading to better therapeutic recommendations.
