Is it possible to rotate the current spin states of electrons of cancer cells with some kind of non-elastic collision via high intensity photon particles to stop cancer progression in last stage.
I don't think so. How would you selectively affect the spin states of the cancer cells? By beam-shaping and modulation? sounds a lot like conventional radiotherapy. Electron not electon.
Cancer is a systemic disease. Before you ever see a stage 1 tumor, there are genome wide epigenetic changes, suggesting that multiple systems are involved. We get many mutations every day. In order for a mutation to survive, multiple DNA repair mechanisms and immune pathways must be dysfunctional. As tumors progress, the heterogeneity of genetic mutations increases, suggesting the cancer is causing mutations rather than mutations causing cancer. Although, there are quantum biological processes involved such as those seen in DNA defense mechanisms, I know of no data that would suggest that changing the spin state of cancer cells in a stage 4 tumor would be an effective treatment. You are essentially talking about a local treatment for a systemic disease in its final stage.
Spin is an intrinsic angular momentum of electron or an associated magnetic moment. Spin quantum number of electron can only be +1/2 and -1/2 and in one orbital there cannot be two electrons with the same spin (Pauli exclusion principle). As a result, if two electrons are in the same orbital, their spin quantum numbers cannot be changed without moving electron to another orbital, which is essentially changing its energetic state. So your question can be understood as treating advanced cancers by changing energy states of atoms (this re-phrasing would be more specific in terms of physics). This would actually cover a spectrum of existing therapies from laser therapy to radiotherapy. As mentioned in previous answers, this is often helpful for local or loco-regional control of the disease, and I would also add pre-cancerous lesions in case of laser therapy, but not in advanced stages with distant metastases. There is also photodynamic therapy, which employs singlet oxygen (an excited electron state of molecular oxygen that also differs in electron spins from ground state of molecular oxygen) to kill malignant cells. Again, all these processes are primarily energy-state related with excitation or ionization leading to higher reactivity and subsequent damage to critical biomolecules. It has no direct connection to spin as an inherent and quantized electron property. It is my personal observation that speculations about quantum physics/chemistry and cancer do not come from people who have developed insight in these disciplines.
