You can reliably train dogs to detect cancer with a high degree of accuracy. The dogs are able to detect the cancer simply by sniffing clothing that had been worn by the patient and so there is no contact between the dog and the patient. Since there are no risks from the test, and you know that cancer caught early is often treatable you are keen to develop your idea further. What possible negative consequences would need to be considered before concluding that this type of screening test should be more widely used? You may select more than one answer. a. Risks associated with further tests such as biopsies to type and stage the cancer. b. Risks associated with surgical interventions to remove the cancer. C. Risks associated with chemotherapy used post surgery.arrow_forward
