Tumor refers to the new creature of organ and tissue cells lost its normal body function under the long -term role of the animal body in the absence of various promoting factors, leading to a new creature that causes abnormal hyperplasia or insufficient apoptosis and forms a pathological new creature. Tumor cells do not have the growth form, functions, and loss of differentiation and maturity of normal cells. Continuous growth will destroy the structure and function of the original organ. Tumor is a local manifestation of an integrated disease of the body. Its growth comes from the blood of the body, nutrient supply, and tumor cells absorb a lot of nutrients in the body. The influence causes these normal cells to not grow normally, resulting in malnutrition, anemia, and weight loss throughout the body. Tumor cells not only seize the nutrition of normal cells, but also produce a lot of harmful metabolic substances. These substances act on other organ tissues and have serious consequences of the body. Tumors will not only occur on animals, but also occur on people, so it should be attracted to the common attention of animals and human medicine.
There are a variety of tumors from the appearance, and there are different sizes and different numbers. Generally, there are one, but there are many. Small tumors can be seen in a microscope. The large tumors can be seen and growing in the heart. Tumors in the body (such as abdominal cavity) are generally large, and tumors born in the skull cavity will be relatively small. Large tumors grow slowly and have a long time, but generally benign; small tumors generally grow rapidly, and the consequences are more serious. It has a large impact on the body. The color of most tumors is gray or gray -red, but there are other colors. Recently, a German Shepherd has a large bag on the thighs behind it. It initially suspected that it was hematoma, but the texture of the hematoma was relatively soft, and it would be smaller after pressing. This bag is very large, and the feeling of pressing is relatively hard. Finally, it is determined to be a benign tumor through tissue examination and cell examination.
Remove tumor
The etiology of tumors is not very clear at present, but according to a large number of epidemiology and research surveys, the occurrence of tumors is related to external factors, mainly chemical factors, viruses, and radioactive substances. Chemical factors cause 90 % of cancer. For example, aromatic hydrocarbons can be spontaneously generated in the environment, and some are artificially synthesized. There are thousands of carcinogenic chemicals. The most common physical factors are ultraviolet rays. People in the empty areas of ozone layer are prone to skin cancer. The goats on the mountains have a high probability of skin cancer due to long -term exposure to ultraviolet rays. Biological factors include viruses, such as chicken leukemia and chicken sarcoma, and many other viruses.
Removal site
This Shepherd's tumor is very large and diagnosed as a benign tumor. Therefore, surgical resection method can be used as the best treatment method, and the impact on the body is not great. Generally, benign tumors will not recur after the resection. After surgery resection, the surgery is removed. Treatment of antibiotics. Animal tumor is not very common. The owners of pets should pay attention not to bring dogs near some chemical factories, eat less pickled food, maintain good living habits, and maintain a clean living environment. Prevent tumors.
