Cancer cells self seed, promoting tumor growth and metastasis
by on 27. Dec, 2009 in Health News
New research published December 24 2009 in the journal Cell, shows that cancer cells can self-seed, causing increased tumor growth and metastasis. Until now, the process of how cancer spreads to distant organs was not known, and thought to be the result of tumor growth alone. The findings are important, and shed new light on the future of cancer treatment. The new findings that cancer cells self-seed means that malignant cancer cells find their way back to the primary tumor. Signals sent out from the cancer tumor attract those cells back. When that occurs, cancer cells then become aggressive, metastasize and grow. The research leading to the discovery was performed [...]
