ABSTRACT
Many diverse developments have happened in the 21st century.
There are artificial organs, like eyes, skin, and bone, or stem cell treatments in the brain, liver, heart, eyes, and more.
There is targeted therapy for cancer by blocking cells that are involved in tumor growth and identifying cancer cells and killing them.
The control of heart diseases has made the number of deaths caused by heart diseases to drop notably.
There are large improvements in HIV medicine, from monotherapies (single-drug treatments) to combinations of drugs into one medicine.
The Leksell Gamma Knife, used for treating cancers in the brain, was constructed and launched. It consists of 201 cobalt-60 sources, each with an activity of 1.1 TBq (terabecquerel). Each of these 201 radioactive sources points to a small target in the brain that will kill the cancer cells.
Proton therapy came into clinical use, and many centers have been created for high-precision radiotherapy.
3D-printed body parts have come into testing and are a growing discipline.
Maybe the nanomedicine adventure is one of the most exciting developments. Nanotechnology can be used for many things in healthcare, from the transport of medicine with impressive precision, making them the leading way to avoiding harming sensitive tissue. Today, more than 130 nanomedicinal drugs have been developed around the world.
