This assignment focuses on cancer risks and causes.
Breast Cancer Risks, Genetics, and the Environment
Cancer is a nonselective disease. Cancer can occur at any age, and although treatments have been improved, cancer still can be a deadly disease. Some cancer is linked to environmental causes such as cigarette smoke or UV radiation. Other causes may be genetic, such as inheriting the gene for breast cancer. Early detection can impact the outcome of cancer; therefore, it is important to recognize early symptoms and tests for prevention.SHOW LESSTanya has received some troubling results from her "23 and Me" DNA test. She has inherited the BRCA1 gene for breast cancer.Even though Tanya has the breast cancer gene, it does not necessarily mean she will ever develop breast cancer. However, she does have a chance. In this unit, you are going to evaluate the medical histories and breast cancer risks of Tanya’s friends and estimate how they might reduce their risks. You will learn about the various risk factors, both genetic and lifestyle related, as well as prevention methods for breast cancer.

Use Chapter 12 in your Visualizing Human Biology text to learn about cancer biology, causes, risks, genetics, and prevention. Why do some people get cancer, and some do not, even if they are related and have the same environment?
With advancements in medicine, genetic testing can be used to determine if you have the gene for a specific type of cancer. For example the BRAC1 is a gene for breast cancer, but just because you have the gene you may not develop cancer; however, it still gives a person a greater risk. In this assignment, you are going to evaluate the medical histories and breast cancer risks of Tanya’s friends and estimate how they might reduce their risks. You will learn about the various risk factors, both genetic and lifestyle related, as well as prevention methods for breast cancer.
For this assignment, you will use a Patient Case Study Profile Form [DOCX] to evaluate four patient profiles and their medical histories. Refer to the resources listed in the Breast Cancer Risks, Genetics, and the Environment section.
Examine the four patient profiles and medical histories of Tanya’s friends (Mary, Paula, June, and Nora) with respect to their breast cancer risk.
Use the various resources presented to help you analyze the cancer causes for each profile.
