Graphene is an allotrope (form) of carbon consisting of a single layer of carbon atoms arranged in an hexagonal lattice. It is the basic structural element of many other allotropes of carbon, such as graphite, charcoal, carbon nanotubes and fullerenes.
In cases where surgery and radiation are combined, proton therapy is an ideal part of brain cancer treatment. Different brain tumors require different doses of radiation for control and eradication. Like any other organ in the body, the brain can only tolerate a limited amount of radiation.
Neutron Beam Therapy. Like proton therapy, neutron beam therapy is a specialized form of radiation therapy that can be used to treat certain tumors that are radioresistant, meaning that they are very difficult to kill using conventional radiation therapy. Neutron therapy can also be used to treat certain inoperable tumors. Stereotactic Radiotherapy Stereotactic radiotherapy is a technique that allows your radiation oncologist to precisely focus beams of radiation to destroy certain types of tumors.
