DNA sequencing reveals how rare cancer spread between twins before birth
Two identical sisters came into the world carrying the same rare cancer. They lost their lives to an undifferentiated sarcoma, a soft-tissue cancer driven by a unique gene fusion (MN1::ZNF341). The story began before they ...
Genomic cancer driver study reveals new clues to why some prostate cancers become aggressive
Why do some prostate cancers grow slowly for years, while others progress quickly to life-threatening metastatic disease? An international team of researchers co-led by the Ontario Institute for Cancer Research (OICR) and ...
