Of all cancers, 8.5% subsequent (8.4% for males 8.7% females). SIRs both elevated with upper aerodigestive tract, colon, nose, breast, other female genitals, testis, kidney, urinary, bladder, skin, nervous system, endocrine, bone, connective tissue, melanoma, lymphoma leukemia. risks some sites, such as squamous cell bone tissue sexes, breast tract leukemia females, very high (>10).
