Canine lung cancer can occur in two forms. Primary canine lung cancer is a more uncommon form of the malignancy that stems from the lungs itself. The cause of the disease is considered to be inhalation of second hand smoke with inadequate filtration of carcinogens. These cancerous cells are known to invade the adjacent lymph nodes located in the upper part of the chest and even the central nervous system. The second variant of canine lung cancer is metastatic lung cancer that is characterized by growth of cancerous cells, whose site of origin is in some other part of the body and have thereafter invaded the lungs. Lung cancer when contracted by dogs at a young age tends to spread throughout the body at a very fast pace.
As in the case of human beings, lung cancer in canines also does not produce any evident signs of its occurrence in the initial stages of malignancy. With the progression of the disease, one of most prominent symptoms is a persistent cough without any mucus. However, at times, cough may be accompanied by small proportions of blood or phlegm.
Some of the other signs of the disease include decrease in appetite, weight loss, fatigue, respiratory disorders owing to the compression of the wind pipe or collection of additional fluid surrounding the lungs, and lameness in cases where the cancer invades the limbs.
