SABR or RFA for lung cancer?

After successful surgery for colon ancer in 2022 and liver cancer in 2024 I was diagnosed with lung cancer in February this year - 2 small tumours in each lung. The right hand lung was treated with radio frequency ablation (RFA) in October which caused considerable pain afterwards but seems to have been successful. Now it's time for the left hand lung to be treated either with RFA or with SABR (highly targeted radiotherapy). Does anyone have experience of SABR which they could share with me? Thanks.
