We investigated the incidence of invasive cancer of the breast, ovary, and uterus in a cohort of patients who had undergone in-vitro-fertilisation (IVF) treatment and examined whether cause of infertility or exposure to fertility drugs to induce superovulation was associated with an increased cancer risk. ⋯ Women who have been exposed to fertility drugs with IVF seem to have a transient increase in the risk of having breast or uterine cancer diagnosed in the first year after treatment, though the incidence overall is no greater than expected. Unexplained infertility was associated with an increased risk of a diagnosis of ovarian or uterine cancer.

Children's doses of drugs are prescribed according to bodyweight but in resource-poor countries weighing scales may be unavailable, inaccurate, or broken. We designed a length/weight tape for use in our community and found it reasonably accurate for weights of 4-16 kg and better than a clinician's guess.
