Cancer treatment methods comprising a step of applying remote conditioning to the cancer subject, for example remote ischemic conditioning via several episodes of short-term limb occlusion. Upregulation and release of remote conditioning substances such as microRNA 144/451 cluster endogenously caused by remote conditioning may be beneficial in reducing the growth and proliferation of malignant cells. Remote conditioning may also be beneficial when combined with chemotherapy or radiation therapy as it may improve survival of healthy surrounding tissues and minimize side effects of these known cancer treatments. Remote conditioning may be non-invasively applied by a medical professional or self-applied by the cancer subject at home using an automatic device. The novel cancer treatment methods may be used for lung cancers, liver cancers, colorectal cancers, digestive cancers and other cancers.
