Mae canser yr ysgyfaint yn un o'r mathau mwyaf cyffredin o ganser ledled y byd.
Yn ôl y Sefydliad Iechyd y Byd (WHO), canser yr ysgyfaint yw'r prif achos o farwolaethau canser yn fyd-eang, gydag amcangyfrif o 1.8 miliwn o achosion newydd a 1.6 miliwn o farwolaethau yn 2020.
Yn yr Unol Daleithiau, dyma'r ail ganser mwyaf cyffredin mewn dynion a menywod, gyda tua 228,810 o achosion newydd yn 2021.
Mae'r cyfraddau achosion a marwolaeth o ganser yr ysgyfaint yn amrywio yn ôl rhanbarth, gyda cyfraddau uwch mewn gwledydd datblygedig ac ymhlith dynion.
Fodd bynnag, mae'r achosion o ganser yr ysgyfaint wedi bod yn gostwng yn ystod y blynyddoedd diwethaf oherwydd gostyngiad mewn lledaeniad ysmygu.
