# 1901 in oncology

Source: https://onco.cc/years/1901/  
OnCo record `1901` (Year). Data CC BY-NC 4.0, attribute "Data from OnCo (onco.cc)"; commercial use needs a licence.

## TL;DR

OnCo holds nothing dated to 1901. That is a gap in what has been read into the corpus, not a claim that the year was quiet, and the year has a page so the gap can be seen rather than passed over.

## Summary

No record in OnCo carries a date in 1901. The corpus reads the field through its records, so an empty year means nothing has yet been read into it, and says nothing about what happened.

Years from 1900 onwards all have a page, empty or not, so that a gap in the reading is visible. The timeline shows which parts of the record are thin and why.
