A Pea Grows in Sveden

That's 'Sveden' as in Ron Sveden.  A pea plant was removed from Mr. Sveden's lung earlier this month. 

Mr. Sveden, a 75-year old lifelong smoker, was just about convinced he had lung cancer.  But, after several hypotheses proved wrong, a biopsy showed the one-and-a-half inch long pea plant growing in one of his lungs.  Sveden and his doctors believe that while eating peas, one went into his windpipe, lodged to his lungs and began sprouting.
