Well, I just found out what I have: a common lung cancer, Adenocarcinoma.

24. Go n-ir an bthar leat,

Go raibh an ghaoth go brách ag do chúl,
Go lonraí an ghrian go te ar d’aghaidh,
Go dtite an bháisteach go mín ar do pháirceanna,
Agus go mbuailimid le chéile arís,
Go gcoinní Dia i mbos a láimhe thú.

Or, in English:
May your journey through life be successful/prosper,
May the wind be always at your back,
May the sun shine warm upon your face,
May the rain fall softly upon your fields,
And until we meet together again,
May God keep you in the palm of his hand.

You've got this!
