Describe the two general ways radiation is currently used to treat cancer.?

Answer 1

Two? There are many, but the two general categories are beam radiation and seeds (brachytherapy). Beam radation means that a radiation source external to the body is aimed at the location of the cancer. This differs from seeding, which involves implanting tiny bits of radioactive material directly into the tumor.Within these two categories, there are many alternatives, such as proton beam, IMRT, etc.
