It's not absurd, it's statistics. If you're trying to detect something that's fairly rare, it's very easy to have a test produce more false positives than real positives.
That means if you randomly take a test and it has a positive result, it's more likely you do NOT have the cancer than do.
More detection of cancer and earlier is great. But testing has it's limitations and the general public doesn't always understand the statistics involved to apply the tests correctly.
