Get some insight on Dog lung cancer

Dog cancer is a disease of middle-aged and older animals. This type of cancer, primary or secondary. Primary lung cancer is due to the tissue of the lungs and airways prone, and to a single, discrete mass. Secondary tumors have spread from tumors in other parts of the body has. Malignant cells from bone cancer and breast cancer can move through the lymphatic system and cause many small tumors in the lungs. The majority of tumors in the lungs of dogs to be found are secondary tumors.
25% of lung cancers are asymptomatic dog, which means that the affected dogs no indication that it shows a problem with the lungs. Her tumor show up on a chest radiograph if they are tested for an independent state. A diagnosis of cancer comes as a terrible shock to their owners.
Dogs who can live with smokers have an increased risk of primary lung cancer.
Diagnosis
Animals with cancer are affected dog show, often symptoms of lung diseases, including a cough and difficulty breathing. They are also less able to move in and out of breath sooner than normal. As the disease progresses, they will lose weight and may vomit their food is expressed as the tumor in her esophagus.
Radiographs of the chest of an affected dog is either a single mass on one part of the lung or a granular appearance point to all areas of their chest. If the tumor on the outer part of the lung, it may be possible to go a needle into the ground and take a sample of cancer cells. Other diagnostic methods include passing a bronchoscopes in the airways to a biopsy of the tumor, or inject sterile fluid to take in the trachea and suck them, hopefully collect some cells simultaneously. These cells can be examined under a microscope to determine what type of tumor and the likely prognosis.
Forecast
Survival after treatment for primary lung cancer is on average 12 months. Forecast is slightly better for the dogs that no symptoms of the disease, has a single small tumor and no evidence of spread of cancer cells in lymph nodes. In these cases, many dogs have cancer-free years, but many of these animals eventually develop multiple tumors in other parts of the lung.
If your dog needs a chest x-ray for another reason, one can not expect, dog lung cancer are increased if they show symptoms of the disease. But early diagnosis generally results in a better response to treatment, so if your dog coughs or makes their breathing, they give your veterinarian sooner rather than later.
