Biomedical research is an approach used towards solving medical problems.
It deals with beliefs or theories which can be proven or disproven through observations and experimentation. Before humans can be asked to participate in testing, researchers must first use animals whose living systems best represent that of humans. Almost every major medical advance in this century has been dependent on animal research and it remains critical to unlocking the cure to many diseases which still claim the lives of millions. Science generally starts with an unanswered question or problem in the mind of the researcher. All important information is collected and studied, and possible solutions to the problem are proposed that help direct the researcher to the facts.
