Enough diagnostic tools? Hah. Most cancer detection assays are pretty much garbage if you were to compare them to the latest advances in say deep learning image recognition models.

You can actually compare the sensitivity/specificity for PSA prostate screens versus something like ResNet for image recognition. The latter is in the high 90s for both metrics. The former can be as low as 0.06 for specificity if you want to actually achieve high sensitivity (detect prostate cancer with extremely extremely high false positives)
