I didn't understand how I could benefit from genetic testing; I don't have children nor am I planning on having any, how could I benefit from knowing the details of my genes? Genetic testing is important because it can predict which genes I carry, ergo which diseases I am susceptible to; preventative medicine can be taken if necessary. Dr. Jennifer Wagmiller, the oncologist that I went to for a second opinion at St. Barnabas Cancer Center, recommended that I get the supplementary testing; I obliged. Julie Reichling, the genetic counselor at St. Barnabas Ambulatory Care Center, sketched a thorough ancestral tree, asking me the medical history of relatives I didn't even know the names of; I became frighteningly aware of how much I need to learn. Ancestral trees aren't only important for names, but also for medical history! I filled in the blanks of the evident: thyroid, skin and colon cancer that effected my immediate family; the information I provided determined the type of genetic test needed. Out of curiosity, I messaged my estranged cousin when I got home; he detailed the relatives whose lives were taken by breast cancer and leukemia. I updated Julie, who dutifully notified the lab. Six weeks passed and my results proved to lack concern, but I'm to return in a few years for re-testing - medical revisions.
