Cancer stem cells are sometimes called “mother cells” because they are the precursors to the “daughter cells” that multiply to create tumors. As the researchers noted, chemotherapy is not effective at killing these mother cells and therefore in many cases, the cancer returns.
From the research findings:
“Cancer stem cells pose serious obstacle to cancer therapy as they can be responsible for poor prognosis and tumour relapse. To add into the misery, very few chemotherapeutic compounds show promise to kill these cells. Several researchers have shown that cancer stem cells are resistant to paclitaxel, doxorubicin, 5-fluorouracil, and platinum drugs. CSCs are thus an almost unreachable population in tumours for chemotherapy. Therefore any compound, that shows promise towards cancer stem cells, is a highly desirable step towards cancer treatment and should be followed up for further development.”
Ginger has been proven to be effective in killing ovarian and prostate cancer cells – further research could lead to more effective treatments that do not harm healthy cells in the human body, unlike chemotherapy and radiation treatments.
