Cancer is not an easy topic for anyone. It rips through families causing physical and emotional stress. It can be especially traumatic when cancer affects the family pet.
Cancer is hard to detect. It is not visible in blood tests, nor does it always show up with external signs. Change in eating habits, lack of energy, and difficulty relieving themselves are all signs your pet has something going on, however, does this mean they actually have cancer or just ate something they shouldn't have?
An additional sign to look for can be abnormal swelling. Bumps that keep growing should be watched. It's best practice to have it looked at by a veterinarian. It may need to be biopsied and removed.
Strange odor is also a red flag. Odor can stem from bad bacteria and pus which indicates an infection of some kind. Check out where the smell is coming from. Is it simply a cut? Is there discharge? Is it not healing? Have this checked out!
Difficulty breathing is never a good thing. It means there is pressure on the respiratory system, which may be a mass. This should send major alarm bells to any pet owner. If this is the case, your pet may have to be taken in to an emergency vet as soon as possible.
Early detection is key. None of these are a "sure sign" that your pet has cancer. It is always best to check with their vet and have any issues taken care of immediately! Pay attention to your pet. Petting them and monitoring their eating and playing may save their life.
