The primary reason why conventional chemotherapy and radiotherapy have failed to produce any significant improvements in cancer survival rates is that cancer stem cells are resistant to these interventions. In fact, chemotherapy and especially radiation are both capable of increasing the number and virulence of these cells in a tumor, while at the same time having the well-known side effect of further damaging the patient’s immune system.
While the cancer industry is still very much resistant to incorporating the implications of these findings into their standard of care (which is highly unethical), there are an increasing number of health practitioners that will not turn their back on the truth and are very much interested in alternative ways to prevent and treat cancer using food and/or plant-based approaches.
The new study addresses the relevance of cancer stem cells as follows:
The cancer stem cell model suggests that tumor initiation is governed by a small subset of distinct cells with stem-like character termed cancer stem cells (CSCs). CSCs possess properties of self-renewal and intrinsic survival mechanisms that contribute to resistance of tumors to most chemotherapeutic drugs. The failure to eradicate CSCs during the course of therapy is postulated to be the driving force for tumor recurrence and metastasis. Recent studies have focused on understanding the unique phenotypic properties of CSCs from various tumor types, as well as the signaling pathways that underlie self-renewal and drug resistance.
At present, the cancer industry has failed to produce a single drug that targets the cancer stem cell population of cells within a tumor, as confirmed by the study:
If indeed the CSC response is a vital criterion for cancer treatment evaluation, there are still no drugs in clinical use that specifically target CSCs.
