Re: Cancer Cure?

Since DNA damages and its repair is normal cellular mechnisms,
Have/Can't it be pursued? Can there be changes in cells structure
membrane etc. pre- cancerous mutations to get mutations? What changes
cells can experiance before becoming cancer cells in its structure
other than DNA damges for cancer? Whether hyper/hypo tonicity of body
fluid can be related change in morphology of cells resulting into
cancerous mutations?
