Revolutionary At-Home Cancer Screening Test Uses Dog’s Sense of Smell
A groundbreaking advancement in cancer detection is on the horizon, thanks to Israeli startup SpotItEarly. They are developing an innovative at-home cancer screening test that combines the remarkable olfactory abilities of dogs with cutting-edge technology. This unique approach aims to provide an early, non-invasive method for cancer detection, potentially saving lives through timely intervention.
How the Canine-AI Cancer Screening System Works
The process is elegantly simple:
- A test kit is delivered to your home.
- The user breathes into a specialized mask similar to an N95 for three minutes.
- The sample is then mailed to SpotItEarly’s laboratory.
The Role of Trained Dogs in Cancer Detection
At the lab, a team of expertly trained dogs will analyze the sample. Their exceptional sense of smell enables them to identify the presence of cancer. Shlomi Madar, CEO of SpotitEarly, emphasized the natural aptitude of dogs for this task. “Our dogs are natural workers and love being mentally stimulated by their sense of smell. Training them to detect odors wasn’t a challenge; it is in their nature,” he explained. He also noted that a dog’s sense of smell, with approximately 250-300 million receptors, is 10,000 to 100,000 times more sensitive than a human’s. This heightened sensitivity makes them highly effective for scent-based tasks.
The dogs are trained to identify cancer odor signatures within a patient’s volatile organic compounds (VOCs). VOCs are biological markers from blood in our lungs that are released in our breath.
Artificial Intelligence Enhances Canine Detection
The true innovation lies in the fusion of canine proficiency and artificial intelligence. “As the detection dogs are sniffing the samples in the lab, we use our proprietary AI platform, LUCID, to track and analyze their physiological and behavioral signals, collecting thousands of data points per second,” Madar stated.
LUCID analyzes the data and will generate a lab result if a cancer signature is found in a sample. This fusion of advanced technology with the extraordinary olfactory abilities of canines enables rapid sample screening, making the solution highly scalable.
Aiming for Earlier Cancer Detection
SpotItEarly’s primary goal is to identify cancers at earlier stages, when treatment is more effective and less costly.
“Too often, cancer diagnoses come too late,” Madar said. “Our goal is to reduce late-stage and potentially fatal cancer diagnoses. The data is clear: when we detect cancer earlier, we significantly improve survival rates and outcomes.”
Availability and Cost
The at-home cancer screening test is currently in late-stage development and is projected to be available commercially in 2026, with an anticipated cost of $250 per cancer type. Bundled discounts will be offered for screenings of multiple cancers. The company intends to collaborate with health insurers to ensure coverage and alleviate financial burdens on patients.
Clinical Study Results
In a recent clinical trial, SpotItEarly’s cancer-screening method achieved an impressive 94% accuracy.
Reducing Barriers to Cancer Screening
The at-home test aims to address a critical issue: the avoidance of routine cancer screenings due to discomfort and invasiveness. “Many individuals avoid routine cancer screenings because they can be uncomfortable and invasive,” Madar said.
“By simplifying the process to a self-administered screening test where users just breathe into a mask, [this] levels that barrier and encourages more proactive testing.”
Traditional screening tests currently detect only 14% of cancers in the US. SpotItEarly aims to enhance the cancer diagnosis and treatment landscape, transitioning from reactive “sick care” to proactive health care.
The Well-being of the Detection Dogs
The dogs’ welfare is a top priority. They work a few hours each day in teams, receiving treats and affection as rewards. During their off-hours, they enjoy outdoor playtime, belly rubs, and human interaction.
Upon retirement, the dogs are adopted into loving homes, often by their former handlers. Madar emphatically stated, “Our dogs are not lab animals; they’re truly a part of the SpotItEarly team.”
Future Applications
While the initial focus is on cancer, Madar believes the technology could potentially be adapted to detect other diseases, such as Parkinson’s and serious infections.
“We aim to make early diagnosis the norm, consequently increasing the chances of survival at scale,” he said.
