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.
Proton therapy can deliver effective cancer treatment, with a low risk of side effects. Targeted treatment is always important for cancer treatment, but it can be especially crucial for patients who have tumors in delicate areas of the body.
