Invited Commentary: Reproductive Organ Surgeries and Breast Cancer Risk--Apples, Oranges, or Fruit Cocktail?

Invited commentary: reproductive organ surgeries and breast cancer risk--apples, oranges, or fruit cocktail?

Case-control and cohort studies are almost always complicated by nonrandom exposure allocation, which must be minimized in the design and analysis phases. Tubal sterilization is a common gynecological procedure that may be associated with other reproductive organ surgeries, which in turn may be associated with breast cancer risk. In this issue of the Journal, Gaudet et al. (Am J Epidemiol. 2013...

More than apples and oranges - Detecting cancer with a fruit fly's antenna

Cancer cells and non-cancer cells differ in their metabolism and they emit distinct volatile compound profiles, allowing to recognise cancer cells by their scent. Insect odorant receptors are excellent chemosensors with high sensitivity and a broad receptive range unmatched by current gas sensors. We thus investigated the potential of utilising the fruit fly's olfactory system to detect cancer ...
