It is estimated that 589,430 people in the United States will die from cancer in 2015 (ACI, 2015). Watching a loved one die of cancer is heartbreaking. Watching a loved one suffer from the side effects of cancer treatment is just as difficult. The battle to treat cancer has been stressful and hard on patients. Today, the most popular way to treat cancer is chemotherapy. Chemotherapy is a way of treating cancer using chemicals, including anticancer drugs. Nanotechnology is a new and emerging way to treat cancer. Nanotechnology is the science of regulating matter at the molecular level (NCI, 2012, Para 1). Nanotechnology provides the power to selectively treat cancer cells unlike chemotherapy. Nanotechnology is a more effective way to treat cancer than chemotherapy because it offers the power to selectively treat cancer cells without harming normal cells and causing fewer side effects in patients. Nanotechnology is more powerful in selecting cancer cells and killing them, while chemotherapy is not as effective and has several side effects. Chemotherapy creates several dangerous side effects, including toxicity to vital organs following the destruction of normal cells. (Gunjal, Schneider, Abdelbaset, Kakar, Kucia, & Ratajczak, 2015, p. 1). Having the ability to treat only cancer cells with nanotechnology is a safer alternative and causes much less pain to patients. During cancer treatment, nanotechnology does not kill normal cells while chemotherapy destroys countless healthy cells. Nanotechnology is able to distinguish cancer cells from normal cells in magnetic resonance imaging using particles such as iron oxide nanoparticles, gadolinium nanoparticles and gold nanoparticles (Mody, Pharm, 2011 pg...... middle of paper..... Elements involved in chemotherapy include toxicity to vital organs resulting from the destruction of normal cells (Gunjal, Schneider, Abdelbaset, Kakar, Kucia, & Ratajczak, 2015 , p. 1).The special skill provided by nanotechnology allows the treatment to be safe still today and will continue to grow with time and research. pathologies like cancer. Although nanotechnology still requires some research to overcome some obstacles, nanotechnology has turned dreams into reality, a safer cancer treatment is being studied and researched and has a huge possibility of replacing chemotherapy. It should give hope to friends and families if they ever learn that a loved one is diagnosed with cancer. Winning the battle against cancer will no longer be such a painful struggle in the future thanks to nanotechnology.
