Review Questions

• How have technological advances since 1900 influenced the understanding and treatment of cancer?
  • Technological advances since 1900 have greatly transformed the understanding and treatment of cancer. Improved imaging techniques like MRI and CT scans allow for earlier detection, leading to better survival rates. Additionally, advancements in molecular biology have revealed insights into cancer genetics, which have paved the way for targeted therapies. These innovations have not only enhanced treatment options but also refined diagnostic procedures, enabling a more personalized approach to cancer care.
• Evaluate the impact of chemotherapy and radiation therapy on cancer treatment post-1900 and discuss their limitations.
  • Chemotherapy and radiation therapy have played critical roles in treating cancer since their introduction in the mid-20th century. While chemotherapy uses drugs to attack rapidly dividing cells, radiation therapy targets specific areas to kill or damage cancerous tissues. However, both treatments come with significant limitations, such as severe side effects and the risk of damaging healthy cells. This has led to ongoing research into more targeted approaches like immunotherapy, which aims to harness the body's immune system to fight cancer more effectively.
• Assess the broader societal implications of advancements in cancer research and treatment technologies since 1900.
  • Advancements in cancer research and treatment technologies since 1900 have profound societal implications. Increased survival rates from earlier detection and innovative therapies enhance quality of life for patients. However, disparities in access to these advancements highlight issues related to healthcare inequality. Societal awareness and funding for cancer research have grown, fostering a culture of support for affected individuals. This dynamic illustrates how medical progress shapes not only health outcomes but also broader social values regarding health equity and support systems.
