Scientists have discovered that everyday emotional stress is a trigger for the growth of tumors. Any sort of trauma, emotional or physical, can act as a "pathway" between cancerous mutations, bringing them together in a potentially deadly mix.
The findings seem to show for the first time that the conditions for developing the disease can be affected by your emotional environment, including everyday work and family stress.
Until now, scientists believed more than one cancer-causing mutation needed to take place in a single cell in order for tumors to grow.
But researchers showed that mutations can promote cancer even when they are located in different cells, because stress opens up "pathways" between them.
