Conclusion
My personal reaction was interest, because cancer is a close topic to my family. My grandmother was diagnosed with liver cancer and recently passed away. Breast cancer is one of those cancers that can be treated if discovered early, so spreading awareness is one of the greatest prevention methods, in my opinion. Breast cancer is a highly researched topic, and scientists are still discovering new facts and treatments for it.
