ELI5: How come every week there seems to be ground breaking development on defeating cancer but it falls off the face of the earth the following week?
gpt
Several reasons

1 - Cancer isn't one disease, it is thousands.  They may have made progress fighting one variant... but there are thousands of others.

2 - Headlines are usually wrong.  Technically speaking we already know how to cure cancer... just not without killing the patient too.  So when scientists make progress it is touted as the huge success when the reality is probably more like they made some progress in one area.

3 - These things take time.  It can take years (if not decades) for something to go from one success in the lab to an actual medical procedure.
