You have decided to combine your love of biology and your love of dogs to train dogs to detect cancer. 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. Risks associated with chemotherapy used post surgery. C.

Mutations in the BRCA genes have been shown to be related to a higher incidence of breast cancer in humans, and genetic tests are available that enable women to discover whether they carry versions of the gene associated with high risk. However, even early detection of breast cancer does not guarantee a cure. What considerations can you think of for and against advising women to take the tests? ·

Since we do not know the exact cause of cancer and different causes of cancer, write 5 statements (numbered) for 5 recommendations that may help cancer survivors live longer with the least chance of remission. You may use the NOVA knowledge you gained in this module. You may expand your search.

Every year, about a million Americans are diagnosed with cancer. This means that about 75 million Americans now living will eventually have cancer, And one in five will die of the disease. There are many kinds of cancers and many causes, such as smoking, overexposure to ultraviolet rays, a high fat and low fiber diet, and some workplace chemicals. Hundreds of millions of dollars are spent each year on searching for treatment, yet less money is spent on prevention. Should we devote more resources to treating cancer or to preventing it? Explain.
