My senior Lab has a soft lump on his chest and neck. Is it serious?
Hello, sorry to hear about Pounder. It sounds as though that lump may be a fatty tumor especially if it is not painful, firm, or hot to the touch. Other causes may include a malignant tumor which may need to be further assessed. The best way to obtain a diagnosis on benign vs a malignant mass is to get a needle aspirate of it and look at the cells under a microscope. Sometimes, a biopsy may also be necessary to obtain a diagnosis.
The mass may be associated with his ear sensitivity, although, him being a lab, I would be suspicious of a separate issue with his ear such as an ear infection.
Since Pounder is otherwise eating and drinking ok, I would recommend scheduling an appointment with your veterinarian at your best convenience to have his mass and ears looked at. Unfortunately, Labs are notorious for getting cancer and I would not recommend just monitoring this mass.
Best of luck and hope this helps!
