Review Questions

• How does cancer genomics contribute to personalized medicine in treating cancer patients?
  • Cancer genomics allows for personalized medicine by analyzing the specific genetic mutations present in a patient's tumor. This information helps doctors tailor treatment plans that target those unique mutations, improving the likelihood of successful outcomes. Instead of a one-size-fits-all approach, patients receive therapies specifically designed for their cancer's genetic makeup.
• Discuss the role of big data in advancing research within cancer genomics and its implications for future cancer treatments.
  • Big data plays a crucial role in cancer genomics by enabling researchers to analyze vast amounts of genetic information from numerous patients. This analysis helps identify common mutations and patterns across different types of cancers, leading to insights that inform new treatment strategies. As data collection and analysis techniques continue to evolve, big data will likely lead to more effective and targeted therapies for cancer patients.
• Evaluate the ethical considerations surrounding cancer genomics research and how they might affect patient care and public trust.
  • Ethical considerations in cancer genomics include issues related to genetic privacy, informed consent, and potential discrimination based on genetic information. These factors can significantly impact patient care by influencing whether individuals feel comfortable participating in genetic studies or sharing their genomic data. To maintain public trust, researchers and healthcare providers must prioritize ethical standards and transparency while navigating these complex issues.
