While Carlos was studying Biology in the U.S., his father was diagnosed with Philadelphia Chromosome positive Acute Lymphocytic Leukemia (Ph+ALL) in Mexico. The same condition which he’d just learned about in school and had captured his intellectual curiosity was also now very personal. Carlos shares how genetic testing opened up options for his father’s course of treatment but also introduced myriad decisions to be made about his father’s care, the burden of which fell almost entirely upon his mother. He discusses how he thinks a genetic counselor could have helped the family through these many decisions and also shares his perspective on the importance of end of life care.
