Symptoms of dog malignant tumors and the symptoms of benign tumors

First, what is the tumor
Plasting the regiments after the cell growth is out of control. Tumors can be divided into two types: benign tumors and malignant tumors.
The benign tumor refers to the agglomeration of cells that grow irregularly, combined with the surrounding tissues, and there is a dividing line without infringing the surrounding tissue.
The malignant tumor refers to the out of control of the mutation gene and infringe the surrounding tissue.

. The cause of dog tumor
The causes of human tumor many, which can be summarized as the following reasons:
1. Carcinogenic genes: There are certain congenital abnormal genes in normal cells that interfere with the normal growth and division of the cells, so it can cause tumors to occur. Here is an example to make the breeder easier to understand.
The cancer is like a kind child. Because of the cause of the environment, he becomes very bad (normal cells become cancer cells due to genetic mutations).
② tumor gene abnormalities: genes produced in the body inhibit the growth of tumors. If there is abnormalities, it will cause the growth of the body cells to lose control.
If control means that when the genes that control the body's bad cells (the genes that represent tumors inhibit growth) cannot control small tumors in the body due to mutations, they become large tumors.
2. Cancer in the environment
Viruses: certain viruses make proteins to affect the growth of cells, such as mastoid viruses.
The chemical: insecticides have been confirmed to increase the chance of cancer with pets and pets, such as "poisoning fen", which is commonly used to repel deworming in cotton fields. In addition, preservatives in foods such as nitrate in sausages are used on experimental animals and found that carcinogenic phenomena occur.

3. Radiation
The exposure to the sun for a long time, the ultraviolet rays in the sun can easily cause some tumors. There are also dogs who are exposed to × rays for a long time, and they are also prone to diseases, such as dog leukemia and thyroid tumors.
4. The impact of hormones
Sessor of sterilization surgery within 2 years of age, the chance of suffering from breast cancer will be greatly reduced. Gong dogs who are not sterilized are particularly prone to anal adenoma.

. The clinical symptoms of dog tumors
The early tumor cells are very small, so it is difficult to diagnose. It is easy to find when the tumor diameter exceeds 1 cm, but if the tumor is found is malignant, the tumor is malignant. Then the malignant cells will be transferred to other organs, and different symptoms will occur when different organs are metastasized. The owner can determine whether dogs have tumors based on the following phenomena.
1. Pain
When the tumor is transferred to the bone or other tissues, bow -shaped pain often occurs, especially malignant osteosarcoma and multiple osteoma, which often causes bone dissolving. Therefore, when a dog has a long -term lame, the breeder cannot be ignored, and you should pay special attention to such problems.
2. Heat
usually causes the dog's periodic heating.

3. The wound healing is poor
If found that the wound is poor, you should pay attention to whether there is a possible cancer.
4. Other symptoms
This malignant tumors can be transferred to different organs. Different organs can cause different diseases through blood and lymphatic systems. For example, dogs vomit and cough, reduce appetite, diarrhea, difficulty breathing, glaucoma, suddenly blind or epilepsy and other diseases. Once the dog has the above symptoms, it is necessary to take it to the hospital for examination and treatment in time.

. The judgment method of the dog's tumor
1. Generally speaking, when taking a dog to the hospital, the doctor must first do a detailed pathological examination for the dog (such as auscultation, palpation, and percussion. ), The dog's owner performs some consultation or blood drawing tests related to usual consideration to determine the disease.
The method of instrument and equipment check whether the dog gets cancer.
2. Ultrasonic examination: quite useful, but because the ultrasound cannot penetrate the bones and air, the examination of bones and lungs is limited.
3. Failure scanning and nuclear magnetic resonance inspections: These two types of inspection equipment can detect tiny tumors in early stage. In addition, MRI is also a strong way to check the diagnosis of neural imaging, but there are also some problems.
Because the instruments are more expensive, domestic animal medicine has not yet adopted nuclear magnetic resonance, and only fault scanning is used. The fault scan requires anesthesia every time, and the price of anesthesia is about 3,000 yuan.
4. Endoscope and air glasses: Diagnose the real situation of digestive tract and respiratory tract.
5. Bone marrow sampling: Can understand the tumor in the bone marrow.

. The treatment method of the dog's tumor
The different treatment methods, including surgery, chemistry and radiation therapy for different tumor characteristics. In fact, the treatment of tumors is different, and dog recovery will be different. For example, as long as breast tumors are found early, early surgery, and early treatment, the treatment effect is quite good. But the treatment effect of some tumors is not ideal.
