<p id="wx27">Bij onderzoek naar <a href="/wnl/Tuberculose" title="Tuberculose" wx:linktype="known" wx:pagename="Tuberculose" wx:page_id="19213" id="wx28">tuberculose</a> in lab ratten, vond Fibiger <a href="/wnl/Tumor" title="Tumor" wx:linktype="known" wx:pagename="Tumor" wx:page_id="22037" id="wx29">tumoren</a> in sommige van zijn ratten. Hij ontdekte dat deze tumoren samenhingen met parasitische <a href="/wnl/Nematode" title="Nematode" wx:linktype="known" wx:pagename="Nematode" wx:page_id="199270" id="wx30">nematode</a> wormen die in <a href="/wnl/Kakkerlak" title="Kakkerlak" wx:linktype="known" wx:pagename="Kakkerlak" wx:page_id="375689" id="wx31">kakkerlaken</a> leefden die de ratten hadden gegeten. Hij dacht dat deze organismen de oorzaak van de kanker waren geweest. De ratten leden echter aan <a href="/wnl/Vitamine_A" title="Vitamine A" wx:linktype="known" wx:pagename="Vitamine_A" wx:page_id="104235" id="wx32">vitamine A</a> tekort en dit was de belangrijkste reden voor de tumoren. De parasieten hadden alleen de weefselirritatie veroorzaakt die de beschadigde cellen tot kanker aanzette; elke weefselirritatie had de tumoren doen veroorzaken. Hoewel de link tussen de parasiet en kanker later relatief onbelangrijk bleek, was het idee dat weefselschade een oorzaak van kanker was een belangrijke vooruitgang in het kankeronderzoek.</p>
