The Health Monitor is also said to detect lung cancer symptoms. Does that mean it detects when you have definite lung cancer cells or does it detect the signs that one is at high risk of getting lung cancer?
I'm somewhat concerned if the system gives a wrong diagnosis and the company will eventually be sued by the concerned user/patient.

There is a big difference between saying "You have been diagnosed with cancer, start treatment immediately" and "Your breath contains markers that indicate a higher risk of cancer. Consider a professional checkup."
But that is not my question. I want to know if the monitor measures symptoms that are unique to lung cancer patients, or an increased amount of particles that could lead to lung cancer.
