Even in remission, cancer looms. Former cancer patients and their doctors are always on alert for metastatic tumors. Now scientists at The Scripps Research Institute (TSRI) have discovered why some cancers may recur after years in remission.The findings, published in the journal Cell Reports, show that invasive tumors can begin sending out tumor cells far earlier than previously thought. These escaping cells – which can enter the bloodstream before the primary tumor is detected – may seed secondary tumors that don ' t show up for years.Importantly, the scientists demonstrated that the escaping tumor cells reach the bloodstream by entering blood vessels deep within the dense tumor core, upending the long-held belief that metastatic cells come from a tumor ' s invasive borders.
