A REVIEW ON ELECTROMAGNETICS OF CANCER CELLS: MODELING TO TREATMENT

Abstract

cancer is a world fear and second leading cause of death. Cancer cause about 16% of worldwide deaths according to world health organization. The treatment of cancer by the use of electromagnetic radiations is well practiced in the field of oncology now a day. Many therapeutic techniques are in practice by oncologists for the cure of cancer. Having benefits and cure rate, each cancer therapy technique has some limitations and adverse effects on healthy cells in the surroundings of cancer cells and sometimes on the entire human body. To overcome these limitations and side effects, the low energy electromagnetic methods have been proposed by the scientific community. In this review article we are discussing few electromagnetic cancer therapeutic techniques and modeling of cancer cells. Hyperthermia, terahertz radiations, magnetic field and radio frequency treatment technologies are studied based on the literature survey. One of the important ways of killing the cancer cells is to rise their temperature above 40^ₒ C i.e., therapeutic level. This is the basic principle of hyperthermia. The use of magnetic fields aids in increasing the tumor temperature that further becomes the cause of death of tumor. Terahertz pulsed spectroscopy can be used to differentiate between normal and malignant tissues. Radio frequency radiation is becoming a favorable new defense against cancer. It’s not only has advantageous therapeutic effects in different types of cancer patients, but also has no severe side effects. The main focus of using a therapy is to generate cell necrosis/apoptosis. The mentioned techniques are playing their premier role in the cancer diagnostics as well as in the cancer treatment, with the benefit of very less damage to the healthy cells surrounding the malignant cells.
