Tumours As Complexes?

The Institute of Cancer Research and the Royal Marsden NHS Trust, London plan to target non-cancerous cells in tumours in the search for new therapies (https://www.theguardian.com/science/2022/nov/22/scientists-reveal-new-lines-of-attack-to-raise-cancer-survival-rate). It's apodictic that cancer cells result from mutations. These cells grow in their own way, but the tumour's environment includes a mesh of unmutated cells, recruited from surrounding tissues. These form 'nests' in various parts of the body. The nests can 'seed' the development of secondary tumours. One consequent strategy might be to find ways of stopping cancer cells instructing other cells to come and support them. Lots of new treatment possibilities could then open up in cancer therapy. We might even become less dependent on chemotherapy and radiation treatment, with their unpleasant side-effects.
