A tumor is a pathological growth of body tissues, which arises from the abnormal reproduction of its cells. More often tumors are observed in adult dogs older than 7 years, there is also a breed predisposition.
For example, in German shepherds, boxers, dachshunds, terriers and schnauzers, skin tumors are more common than in other breeds. Caucasian Shepherds , Great Danes, St. Bernards, Rottweilers and Newfoundlands are prone to bone tumors, and cocker spaniels, boxers and some terriers are most often detected by leukemia. Most often in dogs there is a breast tumor, as well as lymphomas, tumors on the abdomen, paw, spleen, skin, under the tail, genitalia, papilloma and lipoma.
Tumors of the breast in dogs
These tumors are most dangerous, since they are malignant in 50% of cases. They develop in adult animals and often lead to death due to metastases of vital organs. Most of this disease is subject to cocker spaniels, terriers, boxers, poodles, dachshunds, pointers and Irish setters, German and Scottish shepherds. One of the reasons consider long hormonal disorders.
Symptoms manifest themselves in the form of soft nodules in the mammary gland, which eventually grow and solidify. Often, this process is observed after false sucking or estrus. Often, tumors affect more than one gland. The main method of treatment is radical surgical intervention, but it is effective only at the initial stage of cancer.
Papillomas in dogs (warts) are quite common, especially in the oral cavity. Often they dot the mucous membrane of cheeks, gums, lips, tongue and pharynx in a huge amount. In appearance, warts are sometimes reminiscent of cauliflower and, as a rule, first appear on the lips, and then spread to the pharynx and oral cavity.
After 1-6 months they disappear. These are benign tumors that are usually caused by the papillomatosis virus of dogs, which is transmitted by contact with a sick animal. Not all are affected, but dogs with a weakened body. The ill dogs acquire permanent immunity to the disease.
Previously, papillomas were only removed, and now they are treated with local injections of phosphenyl with novocaine, splitting papillomas. Fibrosarcomas occur on the mucous membranes of the gums and cheeks. These are dense in consistency of tumors, often recurrent, may be subjected to ulceration. Their treatment is only surgical.
Symptoms, treatment and removal of tumors in dogs
Tumors of bones are more common at the age of 6-7 years in dogs of large breeds (divers, St. Bernards, Great Danes, etc.) and more often affect the long tubular bones of the forelimbs.
Among the symptoms -
- Swelling and soreness in the affected area,
- The dog does not want to get up, especially in the morning
The outcome depends on the speed of diagnosis and the ability to cut out the tumor.
Testicular tumors in males are usually detected in elderly dogs older than 10 years. Every fourth case is found in males suffering from cryptorchidism, most often in collies, boxers, Airedale terriers and fox terriers.
Symptoms are manifested by enlargement and compaction of the testicle, it becomes uneven, and the scrotum swells.
Rarely found in dogs tumor of the uterus. It is only diagnosed by palpation, since it is often asymptomatic. Treatment is possible only operative - ovariohysterectomy.
Tumors of the internal organs are not visible at all, so they are diagnosed rather late. Their symptoms are quite diverse and can vary in the animal's state. These are respiratory problems ( cough in dogs , wheezing, shortness of breath), gastrointestinal disturbances (vomiting, diarrhea in dogs and constipation), metabolic disorders, changes in blood composition, neurological symptoms. These signs can be suspected.
Tumors in dogs are benign and malignant or cancerous. Benign grow like a capsule, which delimits the tumor from surrounding tissues. Therefore, it is removed without consequences. Malignant tumors germinate, penetrating into surrounding tissues and destroying them. They also metastasize - with a current of lymph and blood spread throughout the body. Such tumors can not always be removed and the prognosis of the disease, especially with late diagnosis, when metastases are already detected, is disappointing.
