Lung cancer is the primary cause of cancer death for both men and women worldwide. Only in the United States, 200,000 people develop lung cancer annually. Survival rates depend on cancer stages, such as survival chances are 92% when it is at stage IA. It drops to 13% in the IIIC stage.

Another issue with lung cancer screening is that the screening methods are costly and not always reliable. CT scans have a high false-positive rate. Chest X–rays have a high false-negative rate. Studies have shown that CT scans and chest X-rays can’t detect lung cancers at an early stage.

Now the question is what is the best alternative to these advanced technology solutions? Right now, dogs have the ability to screen cancer better than any advanced technology. It’s absolutely right that cancer sniffing dogs detect lung cancer with 97% accuracy.

How Can Dogs Detect Cancer Better Than Lab Tests?

Smell receptors of dogs are 10,000 times more powerful and accurate than humans. These receptors help them sniff sensitive odors. This cancer screening approach is non-invasive and accurate. Moreover, it is less expensive than other solutions. Death rates due to cancer are pretty high in the USA, but early cancer detection can increase survival chances. Dogs are powerful and effective approach for cancer detection because they have double smelling system.

Human’s nose contains only 5 million sensors, and dogs have almost 300 million sensors. Moreover, dogs contain a second smelling device as well that human don’t have. This smelling device is present in the back of their noses and known as Jacobson’s organ.

Trained dogs use this double smelling system to sniff unique cancer’s odor. It took years to prove the effectiveness of dogs in cancer detection. Thankfully, dogs are now the best approach for cancer detection at the early stages.

How Can Dogs Detect Cancer with 97% Accuracy?

As mentioned earlier, dogs have the ability to detect cancer with high accuracy. Now the question is how can dogs help to detect cancer? Dogs detect cancer by sniffing out the blood, urine, and breathe, skin and other samples.

Dogs can accurately detect cancerous samples. Surprisingly, dogs are a much more reliable and accurate cancer-sniffing method compared to other advanced technological solutions.

Why Dogs Are Better than Advanced Cancer Detection Methods?

Life is more important than money, but here we are talking about the effectiveness of the method. Indeed, cancer-sniffing dogs are the least expensive cancer detection approach, but they are the most effective solution for detecting lung cancer. More importantly, you don’t have to visit labs for frequent tests. You can perform your part of this testing at home and at any time.

Moreover, this method has no side effects or disadvantages like CT scans and chest x-rays. In fact, it is a win-win situation; that’s why dogs are now the most preferred cancer detection method.

Can All Dog Breeds Detect Cancer?

No, not all dog breeds are meant to be cancer detection dogs. Ususally breeds with natural hunting ability can be trained for this task easily.

For example, Lucy is a cross between an Irish water spaniel and a Labrador retriever. Lucy was curious and excitable, and she belongs to a hunting family. The owners of Lucy decided to train her to sniff out something useful. She got the training, and she learned to sniff out kidney, bladder, and prostate cancer during the next seven years.

More importantly, she was able to detect cancer with 95% accuracy. Indeed, it is much better than lab tests. Lucy is now part of clinical trials for canine detection.

How Long Does It Take to Train Dogs for Cancer Detection?

There is no hard and fast rule to answer this question. Different dog breeds have different abilities. Some dogs have natural skills like hunting and sniffing, and they can quickly learn how to sniff cancer. On the other hand, some dogs take time to learn scent detection. So, there is no specific answer to this question.

No one can deny the importance of cancer-sniffing dogs and their effectiveness. If your dog belongs to a hunting breed, then you can train him for cancer detection. Massive resources are required for dog training, so ideally, you can contact a company offering this service. It will save your time and money.

How to Train Your Dogs for Cancer Detection?

In the past, dogs have detected cancers successfully in their owners, which is why dogs are now becoming part of the clinical setting. Dogs detect cancer by sniffing the unique odors in blood and urine serum and other types of samples.

Cancer scents are different than other organic compounds. When you want to train your dogs for cancer detection, provide them with different (cancerous and neutral) samples, and ask them to detect the positive one. Cancer detection isn’t a simple task, so teams of dogs are required to perform this test. These steps can help train your dogs for cancer detection.

·      Play
·      Introduce scent
·      Reward identification
·      Teach alert
·      Reward after alert
·      Teach various scents

Start playing with your dogs. Introduce different scents. Ask them to identify a particular smell. Reward them for finding a correct sample. If you follow this routine, your dogs can be trained for cancer detection.


A dog can be a loyal friend and act as a home guard as well. No one was expecting this amazing cancer-detection ability of dogs. More importantly, they can detect cancer with more accuracy than any other method. Due to their effectiveness, they are now part of the most clinical settings for cancer detection.
