Could less deadly therapies be a better way to keep cancer in check?

While many cancer therapies initially can be very successful, tumors often return and spread when remaining cancer cells develop resistance to treatment. To combat this tendency, Frédéric Thomas of the French National Centre for Scientific Research proposes that cancer researchers take a lesson from our own immune system and explore 'natural adaptive therapies.' Such an approach would mimic the immune system's more restrained way of keeping cancer in check by gradually killing off cancerous cells.
