Dyma un esboniad:

To treat advanced bowel cancer, you have chemotherapy either into a vein in your arm or as a tablet. If the first type of treatment you have (1st line chemotherapy) does not control your cancer, you can usually have a different type of chemotherapy (2nd line treatment).

Diolch hefyd Catrin. Yng nghyd-destun y darn, mae cyfeiriad at 'inital first line chemotherapy'. Tybed ydy 'initial' a 'first line' yn cyfleu yr un peth?

Mae 'first line' yn cael ei ddefnyddio ar gyfer pob clefyd - ee byddai paracetamol yn 'first line' ar gyfer cur pen, tabledi dwr yn 'first line' ar gyfer pwysau gwaed uchel ac ati. Credu bod 'safonol' yn rhy gyffredinol - gan fod lot o gyffuriau'n rhai 'safonol', ond nid o anghenraid yn ddewis cyntaf i drin y clefyd dan sylw.

Bore da Gareth

Dydw i ddim yn arbenigwr yn y pwnc o gwbl, ond wedi cael hyd i ddiffiniad o "first line" yn y cyd-destun hwn, sydd hefyd yn nodi y caiff ei alw weithiau yn "standard therapy" - a fyddai "safonol" yn gweithio neu a fyddai'n rhy llac ei ystyr efallai?

First line chemotherapy, also known as standard therapy, offers the most favorable means of treating cancer. It remains the first line of treatment, and the strongest option available to combat cancer. Not all cancers require chemotherapy as a first line of treatment--it depends on the type of cancer and its severity. If first line chemotherapy fails, as the cancer metastasizes and accelerates in strength, cancer victims require additional types of treatment to counteract more advanced stages
