Shocking news from WDDTY this morning about a study that suggests chemotherapy so much weakens the area around a cancer that it actually encourages cells to spread rather than killing them.
Chemotherapy spreads cancer, scientists confirm
Scientists have discovered something we revealed more than a year ago: chemotherapy causes cancer to spread. The drug promotes cancer growth by attacking healthy cells surrounding the tumour.
The ‘environment’ in which the tumours live in the body can weaken the effectiveness of chemotherapy, and also encourages the spread of cancer by making neighbouring cells immune to treatment.
Researchers from the Fred Hutchinson Cancer Research Centre in Seattle made the discovery when they carried out laboratory tests on prostate cancer cells.
The researchers basically found that a type of normal, noncancerous cell that lives near the cancer area, the fibroblast, sustains DNA damage that drives the production of a broad spectrum of growth factors that stimulate cancer growth when exposed to chemotherapy. This knowledge, they say, will ultimately help to improve the action of chemotherapy but, in the meantime, it is an admission that cancer can spread as a result of some chemotherapy. Not good.
