I don't know if this will help, but I used it when doing a eulogy for my grandpa in August. My aunt, who is an oncology nurse, gave it to me.

Cancer is so limited…
It cannot cripple love,
It cannot shatter hope,
It cannot corrode faith,
It cannot eat away peace,
It cannot destroy confidence,
It cannot kill friendship,
It cannot silence courage,
It cannot invade the soul,
It cannot reduce the eternal life,
It cannot quench the Spirit.
