The Claim

The precision of estimating the progression rate of breast cancer (λ) is highly sensitive to the duration of clinical follow-up after the final screening, such that short follow-up periods result in practically nonidentifiable parameters due to insufficient observation of the tail of the progression time distribution.

In plain English

If doctors don't keep an eye on breast cancer patients long enough after their last screening, they can't tell how fast the cancer is likely to grow — it's like trying to guess how long a candle will burn by only watching it for a few seconds.

  1. Study: Identification of the Fraction of Indolent Tumors and Associated Overdiagnosis in Breast Cancer Screening Trials

    This study found that if doctors don’t watch patients long enough after their last breast cancer screen, they can’t tell how fast the cancer would grow — just like trying to guess how long a plant takes to die without watching it long enough.
