We found four proteins associated with cancer that in observational long time-to-diagnosis analyses, and cis-pQTL and exGS analyses; CD74 and TNFRSF1B were associated with NHL, and ADAM8 and SFTPA2, were associated with risk of leukaemia and lung cancer, respectively. Here, TNFRSF1B is linked to non-Hodgkin lymphoma.
