My final word, before I'm done, Is "Cancer can be rather fun"- Provided one confronts the tumour with a sufficient sense of humour. I know that cancer often kills, But so do cars and sleeping pills; And it can hurt till one sweats, So can bad teeth and unpaid debts. A spot of laughter, I am sure, Often accelerates one's cure; So let us patients do our bit To help the surgeons make us fit.
