Electromagnetism & Cancer
The break of coherence on endogenous electromagnetic fields is the key element on cancer
That endogenous electromagnetic (EM) fields are supporting life and its proper functioning can be viewed in how cancer cells generate variations of those internal EM fields that reveal their pathologic state. Clusters of centrioles that vibrate longitudinally and coherent electric polar vibrations, dependents on water ordering in the cell, are the main source of these specific and coherent EM waves. ...
It is becoming clear that perturbation in the interactions between the cell and its surrounding environment is the driver of malignancy (more than a just a mutated cell that multiplies out of control), between this environmental factors are acquiring importance the biophysical factors (endogenous electromagnetic fields included)
Investigations are bringing the view that cancer is a direct consequence of mitochondrial dysfunction, disturbed microtubule polar oscillations and the generated coherent electromagnetic field , in general it can be said that cancer transformation pathway includes a link with altered coherent electric vibrations, and individual independent activity begin when frequency spectrum is rebuilt and shifted along with disturbances in the spacial pattern of the field .
Moreover, the special characteristic of the electromagnetic fields generated by cancer cells can be used to attract magnetically charged nanoparticles ( with therapeutic purposes for example) 
" A cluster of centrioles thus produces a cluster of centrosomes—a hallmark of cancer cells. With enhanced electromagnetic fields, centrosome clusters provide an attraction for magnetically charged nanoparticles. These nanoparticles however are not attracted to normal cells which with only two (or at most four) centrioles, have a weaker magnetic field."
There is to take into account that there are various layers of electromagnetic fields working in cells as proposed along this web and as mentioned in  (and, in cancer, all these are disturbed)
" Measurements performed on living cells disclosed electric and electromagnetic oscillations. Dielectrophoretic attraction of dielectric particles to living cells was observed and the corresponding frequency of oscillations was assessed in the range below  MHz by Pohl et al. Besides dielectrophoretic measurements of yeast and alga cells, Hölzel  measured oscillations in the frequency range 1.5–52 MHz using a special detection and amplification system. The external electromagnetic field is damped by cancer tissue at the frequency of 465 MHz and its first harmonic. Electromagnetic field generated by living cells in the red and near-infrared regions causes an interaction between them. Elongated BHK cells on opposite faces of thin and thick glass films were oriented in transverse and random directions, respectively. A metal layer (deposited on the glass film) absorbing the electromagnetic field disturbed the orientation effect. The orientation effect was preserved after deposition of a silicon layer strongly absorbing the blue end of the visible spectrum. Cells also detect electromagnetic signals and send pseudopodia to the source of light. Photon emission from living bodies was measured for instance by Popp. Experimental results suggest that eukaryotic living cells can generate an electromagnetic field in a wide frequency spectrum."
Together with those issues, it must be taken in consideration the important role of water and it's relation to EM field, for example resonant frequencies of microtubules in the frequency range of 10–30 MHz and 100–200 MHz are now discovered and water inside microtubules is important because resonant peaks are not observed after release of water from the microtubule cavity, and also exist a viewpoint that cancer generate when interfacial water normal state, that include the regular formation of water coherent domains (CD) that are collection of ca. one million liquid water molecules oscillating in tune with a self-trapped electromagnetic field at some well-defined frequency and that have a dedicated section on this site  , is disrupted as described in 
" Both gene structure and protein structure, according to our thesis, are slaved to the biophysical status of interfacial water; hence, biomacromolecular structures react to supramolecular events. The proposed function of nanomolecular clusters of coherent water in water CDs is discussed. The hypothesis is presented that cationic Al, for example, effectively “short-circuits” the coherent nano-engines of our biomembranes, dramatically disrupting the delicately-balanced structural entropy consumption, necessary for charge separation, and transmission of both energy and information throughout the body. Concomitant increase in interfacial water stress and softening of tissues, with associated disruption of the cytoskeleton, has now been documented by multiple spectroscopic modalities."
And also the Warburg effect, an altered energy transformation processes in cancer cells is a central phenomenon rather that a side corollary, and provoque a change in mitochondrial membrane potential that in turn change the water ordering capacity around it, resulting in increased damping and low condensed energy of vibrations. 
Last to mention, is the fact that there is a increment in biophoton emissions in cancer cells as it is described for example in this investigatión  (there is a complete section  dedicated to biophoton research in this web):
" Only 1% of malignant cells in a normal aggregate, representative of the early stages of cancer development, resulted in conspicuously increased numbers of photon emissions and spectral power spectra that often reflect a total malignant cell population. This combination of photon flux density and spectral power profiles may be a potentially useful (nanotechnology) tool to detect the minute changes in cell activities relevant to oncology."
