Can Dogs Sniff Out Cancer in Humans?
by Surya Gopal
There is no doubt that dogs are amazing sniffers and have a keen sense of smell. From a drop of blood in an Olympic size swimming pool to explosives and narcotics, dogs can be trained to smell anything.
Not only this, but a dog’s olfactory abilities are also so great that they can even sniff out cancer in humans.
Dogs have smell receptors 10,000 times more accurate than humans, making them highly sensitive to every odour.
Can Dogs Smell Cancer?
Dogs can sniff out several medical conditions in humans. Like many other diseases, cancer cells have a distinctly different smell than regular, healthy cells. Through specific cancer traces, or odour signatures and bodily secretions, dogs can thus identify cancer even at an early stage.
Depending on the type of cancer, dogs can detect a few signs in a person’s body through:
Dogs can detect these odour signs and even alert people for the same. If trained well, they can show in their activities whenever they smell the presence of cancer.
Behavioural Signs Dogs Show on Smelling Cancer
Keep an eye on your dog to see if they are showing these changes in their body language-
- Obsessive Licking
- Head Bobbing
- Ears Drop
- Paw Raised
- Frantic Behaviour
If your dog detects cancer, they may act very differently from normal. While some dogs will sniff you constantly, others may lick or bite at lesions on your body. The signs shown by every dog varies depending on their personalities.
Which Types of Cancers Can A Dog Smell?
Dogs can detect many types of cancers in the human body. Even if your dog is not trained properly, they might show some changes in their actions on detecting cancer cells.
Trained dogs are able to detect colorectal cancer from people’s breath and watery stools even at an early stage, with high-level accuracy.
Besides this, dogs can also detect lung cancer from a person’s breath, ovarian cancer from blood samples, prostate cancer from sniffing a person’s urine, and also breast cancer.
Listen to Your Pooch’s Warnings
Dogs have an incredible sense of smell to detect cancer. Of course, they do not know that the smell is linked to cancer, so you need to notice the signs by yourself.
If you notice your dog showing any of the above-listed signs, it can be tough to know what to do. Obviously, you need not worry about cancer every time your pooch acts strange. Do not ignore the signs rather monitor your dogs for how they behave and act around you so that you can determine the issue.
If your dog continues to show the signs for a longer period, it is better to get a health checkup.
The sensitive sense of smell in dogs can be very helpful in detecting cancer at an early stage. If ever your dog acts constantly in a strange manner, it is worth making time for your body checkup. Listen to your pooch’s warnings as there might be no cure for cancer but identifying it early to get proper treatment can be possible.
