Dogs 'sniff out prostate cancer with 98% accuracy,' study finds
A new study from Italian researchers, presented at the 109th Annual
Scientific Meeting of the American Urological Association in Orlando,
FL, found that specially trained dogs were able to detect prostate
cancer from urine samples with 98% accuracy.
For their study, the team wanted to see whether two highly trained
dogs were able to detect prostate cancer-specific VOCs in the urine
samples of 677 participants. Of these, 320 had prostate cancer ranging
from low-risk to metastatic and 357 were healthy controls.

The dogs were then presented with urine samples from patients — some with thyroid cancer and some with benign nodules — and asked to indicate whether each sample had thyroid cancer or not. Their results were compared to a surgical pathology diagnosis and matched in 30 of 34 cases, or 88.2 percent accuracy.
At least for some types of cancer it seems to work. The cancers make chemicals the body doesn't make naturally, the dogs can smell them. Since it's an area of ongoing research a list of what types is going to be subject to change.
