Head and neck cancers are considered late effects of low dose radiation exposure, namely in the former tinea capitis patients who were submitted to scalp irradiation, in 1950-1960, to induce epilation. In fact we have found a high prevalence of thyroid carcinoma and of basal cell carcinoma in the Portuguese tinea capitis (scalp ringworm) cohort we have been following since 2006. Recently, in the Israeli tinea capitis cohort, scalp irradiation has been shown as an independent risk factor for carotid atherosclerosis.
