Fly and louse infestations are readily discerned and remedied in feedlot cattle. Tapeworm and fluke infections are accepted as probable but, given the lack of anthelmintics with realistic efficacy against these infections, these helminths are allowed to persist without treatment. Nematode infections are considered ubiquitous with cattle coming from pasture and are targeted with a macrocyclic lactone, usually in combination with a benzimidazole. Populations of nematodes seem to be effectively controlled by a combination of anthelmintic treatment, animal resistance and resilience, lack of reinfection, and diet.

Background: Population-level mammography screening for early detection of breast cancer is a secondary prevention measure well-embedded in developed countries, and the implications for women's health are widely researched. From a public health perspective, efforts have focused on why mammography screening rates remain below the 70% screening rate required for effective population-level screening. From a sociological perspective, debates centre on whether 'informed choice' regarding screening exists for all women and the overemphasis on screening benefits, at the cost of not highlighting the potential harms.
