Spread of Breast Cancer Linked to Newly Discovered RNA Splicing Mechanism
What kills most people who die from cancer is not the initial tumor. It’s the intolerable disease burden on the body that arises when tumor cells continually expand their numbers after spreading to different organs. In comparison to what is already known about specific mutations that drive early-stage cancer growth – several now targeted by treatments – researchers understand less about the continual accumulation of new abnormalities within tumors and how they eventually generate cancerous cells capable of spreading to other areas of the body through a development called metastasis.
