I work for Owlstone Medical as a software engineer, so ask me any questions and I'll try to answer as best I can. Also, we're hiring! https://www.owlstonemedical.com/about/careers/

I dream of a future where a sensor can detect from your urine/blood/bowel movement wether you have cancer or some disease.

Imagine a push notification to your phone that says you have a 82% chance of having hepatitis or something.

Do you think that could ever be a reality?

Earlier quoted context omitted.

According to your sibling, there are already off-the-shelf sensors that detect some malodors. Maybe we just need to source already-existing components and convince an EE/manufacturing engineer to do a kickstarter?

The problem is that you need to know what chemical you are looking for that's causing the smell. Are there any sensors that can detect a wide range of smells?

A quick google search reveals a number of label free odor sensors, everything is early stage though.

Label free may not be the best phrase for what you meant though. Label free means you are looking at all biomarkers present in a sample, the primary challenge with label free is that we don't know every biomarker to look for or what every biomarker we see means.

Seems once you have enough datapoints you should be able to do something with machine learning to distinguish good from bad smells.
