October 7, 2009, Vancouver, B.C Canada – For the first time in history, BC Cancer Agency scientists in British Columbia, Canada have decoded all of the three billion letters in the DNA sequence of a metastatic lobular breast cancer tumour, a type of breast cancer which accounts for about 10 per cent of all breast cancers, and have found all of the mutations, or “spelling” mistakes that caused the cancer to spread.

The landmark study, which will be published October 8th as the cover story in the prestigious international science journal Nature, helps unlock the secrets of how cancer begins and spreads, thus pointing the way to the development of new breast cancer treatment targets and therapies.

“One in nine women is expected to develop breast cancer, and breast cancer accounts for 29 per cent of all cancer diagnoses for B.C. women,” said Health Services Minister Kevin Falcon. “As a result of the efforts of the scientists behind the study, this breakthrough finding gives further hope to the thousands of women with this terrible disease.”

“I never thought I would see this in my lifetime,” said Dr. Samuel Aparicio, head of the breast cancer research program at the BC Cancer Agency, an agency of the Provincial Health Services Authority (PHSA). “This is a watershed event in our ability to understand the causes of breast cancer and to develop personalized medicines for our patients. The number of doors that can now be opened to future research is considerable.”
