The lights are bright and the air is warm as the doctor walks in. As she sits down, her expression quite worrying, the room suddenly feels cold and imprisoning. As she begins to explain the results of the mammogram, the feeling worsens. The patient feels a sudden wave of nausea as the doctor tells her how there is a tumor growing in her left breast. This scenario plays out for too many women and men in the United States and worldwide. Thankfully though, due to much advancement in the technology of chemotherapy, patients suffering from breast cancer have been benefited greatly. There have been very many developments in chemotherapy since its creation in the early 20th century and those developments have helped doctors to be able to better treat breast cancer. Developments would include things such as what kind of drugs doctors use, how long to administer this life saving chemotherapy, and more specifically how to administer these drugs and make sure they get to their desired target. In fact, in recent years a lot of focus has been put onto precision. Researchers at UC Irvine have discovered a way to help direct the chemotherapy drug doxorubicin to its desired target by developing amino acid sequences that react only to special carbohydrates in tumor cells (Liu). This breakthrough discovery was something totally unseen in the field before. Previously, doctors would have to be very careful as to where they applied certain drugs such as doxorubicin because of how harmful they could be to other parts of the body. Now that researches have discovered a way to make the drug only react to certain polysaccharides found in tumors, doctors don’t have to worry as much about harming other tissues or organs surrounding the tumor and can focus ... ... middle of paper ... ...hemotherapy and others, many more people would have succumbed to diseases such as breast cancer. Chemotherapy development has played a key role in benefiting chemotherapy patients around the world. Works Cited DeVita, Vincent T., Jr., and Edward Chu. "A History of Cancer Chemotherapy."
