Despite a good prognosis for some cancers, because of the fatality and toxicity of the medication associated with it, pet owners often face a dilemma whether to go for treatment or not. Most of time, cancer in dogs occurs in the elderly what makes dogs more vulnerable to side effects of conventional treatment. Surgery has a limited scope because you can delete only parts of the tumor. There is a dire need to explore new areas of cancer treatment. Despite significant progress in this field needs to be done to develop new strategies and drugs that target only cancer cells and normal cells.
The development of any new treatment needs to be aware of the fact that any medication will cure the disease with minimal side effects. To achieve this goal, the therapy has to target and destroy only cancer cells while allowing healthy living cells normal. Try to understand how radiation and chemotherapy work to kill the malignant cells. These therapies make use of the fact that malignant tumors have cells that grow rapidly because of the division while normal cells are mostly in a resting stage. Chemotherapy attempts to intervene in the function of the DNA of cells to divide and multiply and to leave normal cells alone. There is one exception to this rule because even some normal cells in the bone as naturally continue to divide and replacing dead cells all the time.
Moreover, normal cells begin to divide and replace after being given treatment. This leaves a very small margin of error. Another limitation of conventional drugs is the field of repetition. There are a lot of heterogeneity within a single tumor cells. As the tumor grows, some of the cells get little blood supply that makes them divide a small step compared to others in the same tumor. This leads to a few drug-resistant cells and can survive even after curing the patient of the disease. These cancer cells can remain dormant for a time and lead to subsequent recurrence of cancer. On the one hand, surgery has a different set of limitations. Cancer, including canine and feline cancer is a mysterious characteristic to surface when it has metastasized to a neighbor and even vital organs. This eliminates the surgery as an option and the best results in partial removal of a tumor. Therefore, chemotherapy and radiation become necessary. It is only in rare cases such as cancer of the liver where pet owners can tell the condition early in the treatment because symptoms of liver cancer in dogs are quite evident in a first time. The total removal is only in cases of a benign tumor, which is, in most cases, possibly harmless. Moreover, any increase in the dosage of chemotherapeutic drugs or the time of radiation exposure is accompanied and corresponding risk of increased toxicity. Pet owners need to make an educated decision based on the general health of the dog and the risks involved. In fact the owners have to strike a balance between compassion, quality of life after treatment and the benefits to be derived from the treatment. There are containing a combination of selected herbs known for their characteristics. Each of these herbs promotes health in all cells, tissues, and organs in the body. Many of these herbs have been used for centuries in traditional medicine have been investigated clinically.
