Stress linked to cancer

Med India - More stress can lead to the growth and spread of cancer and controlling stress might help to control it, says a recent research finding.A remarkable research finding suggests that stress results in the release of hormones that aggravate growth of cancer. Norepinephrine, a hormone released during stress stimulates cancer cells to produce two compounds which can breakdown the tissue around the tumor cells. This enables the cells to move easily into the bloodstream and travel to other parts of the body leading to metastasis.The research also suggests the same hormone can also stimulate the tumor cells to release another compound that can aid in the growth of new blood vessels that feed cancer cells, hastening the growth and spread of the disease. The work was reported in the latest issue of the journal Cancer Research.
