Mae canser yr ysgyfaint yn glefyd marwol iawn, gyda chyfradd marwolaeth uchel.
Dyma'r prif achos o farwolaethau canser ledled y byd, gan gyfrif am fwy o farwolaethau na chanser y fron, y prostad, a chanser colorectal at ei gilydd.
Dim ond 15% sy'n goroesi dros bum mlynedd ar gyfer canser yr ysgyfaint ac mae'n gyfrifol am un o bob tri marwolaeth gan ganser.
Mae'r gyfradd farwolaeth am ganser yr ysgyfaint wedi bod yn gostwng mewn dynion oherwydd gostyngiad mewn lledaeniad ysmygu, ond mae wedi bod yn cynyddu mewn menywod.
Er gwaethaf y gostyngiad mewn cyfraddau ysmygu, mae canser yr ysgyfaint yn parhau i fod yn epidemig iechyd cyhoeddus sylweddol, ac ni fydd rhoi'r gorau i ysmygu yn unig yn ei drin.

How deadly is lung cancer?
Lung cancer is a very deadly disease, with a high mortality rate.
It is the leading cause of cancer deaths worldwide, accounting for more deaths than breast, prostate, and colorectal cancers combined.
The five-year survival rate for lung cancer is only 15%, and it is responsible for one in every three cancer deaths.
The mortality rate for lung cancer has been decreasing in men due to a decrease in smoking prevalence, but it has been increasing in women.
Despite the drop in smoking rates, lung cancer remains a significant public health epidemic, and smoking cessation alone will not cure it.
