What are the symptoms of cancer in dogs?

Cancer is such a horrible word and something you never want to deal with in your family or pets. However, knowing the common symptoms can help in identifying a problem in its earliest stages which results in a better prognosis. Cancer occurs when the cells in the body grow uncontrollably, invading other good cells and body tissues. Chances of cancer in dogs are as common as it is in humans. It is most common in older pets over the age of 10, and since causes are unknown, it is a difficult disease to prevent. The most common cancer problems and symptoms are – 

Skin tumors which are quite common in dogs. The most frequent tumors are basal cell tumors, melanomas and lipomas. They will be known as lumps or masses anywhere on the body. 
Lymphoma affects a dog’s digestive system as well as the chest, resulting in lethargy, diarrhea, vomiting, difficulty breathing and coughing. Lymphoma can also affect the liver with additional symptoms of a yellow tinge of the skin and gums. 
Abdominal tumors are difficult to diagnose early on. Some tumors are complicated to note in its early stages such as prostate cancer, hemangiosarcoma and mast cell tumors of the stomach. Be aware of any unusual weight loss, pale gums, weakness, protracted vomiting, uncontrollable diarrhea and a notable enlargement of the abdomen.
Mammary gland tumors can affect the older female dog. These tumors are very common and half of them are malignant. An examination can detect a lump felt in the breast tissue. It happens predominantly to the female dog that was not spayed although spayed animals can be affected as well. 
Male dogs in fact can be prone to testicular tumors and the most common signs and symptoms are an unusually large testicle as well as weakness, weight loss and change in appetite.
