9 mutated genes identified in leukemia patients

Chronic lymphocytic leukemia, or CLL, is the most common form of leukemia found in adults in North America. Yet the disease remains poorly understood, according to authors of a new study published in the New England Journal of Medicine.

Dr. Catherine Wu, one of the study authors and an assistant professor at Harvard Medical School, said all CLL cells look the same under the microscope. Yet patients with the cancer can have different outcomes - some live for 5 to 15 years with little or no treatment, others succumb to the disease within two years.

This unpredictability is one of the reasons Wu and her colleagues are attempting to identify mutated genes in the tumors of CLL patients. For this study they collected DNA samples from the leukemia cells of 91 patients and compared the gene sequences, or DNA order, to normal cells.

Human Factor: Conceiving after cancer

In the Human Factor we profile survivors who have overcome the odds. Confronting a life obstacle - injury, illness or other hardship - they tapped their inner strength and found resilience they didn't know they possessed. This week we meet Sarah Werner, who battled advanced cervical cancer at age 26, but who didn't let her diagnosis get in the way of her dream to become a mom.

I do not regret having cancer. Even though I am reminded daily, with visible scars and various pains that I might never be "whole" again, I would not change or alter my experience.

First of all, I learned that I had the strength to face something as daunting as cancer, while still managing to see humor even during my darkest hours.
