Why do we study the human body?
What is Cancer?
Starred thought of the Day
*Open your mind before you open your mouth.*
Today we started a class discussion about why we study the human body, and what is cancer. The discussion started with the importance of studying the human body, of which there are multiple different reasons. We study the human body because we as people are curious, and want to learn more. Humans want to know what’s wrong with them if they don’t feel well, so that’s another reason we study the human body. Others study the human body because they want to figure out a way to make other people better.
I explained that there are two groups of cancer: benign and malignant. Benign describes tumors that are not very dangerous and grow slowly. Malignant is cancer that grows rapidly and can spread (we call it metastasizing.) Because Humans have changed the world in such a way, such as the burning of fossil fuels and trash, and polluting the ground and water, cancer is a serious public health concern, and will probably affect most of you during your lifetimes.
Ideas are important to have, because when there are problems, we as humans can solve them. Science is the major driver of history, not the other way around. All of the wars that humans have fought have utilized new technologies, which has often resulted in the person with the best technology (and therefore, science) to win. The items people have made have all come from ideas; ideas are fundamentally dangerous, in a good or a bad way.
One idea can change the world. In the video we watched in class, a man with an idea is changing the way that we treat cancer. The reason we have you work together “Cooperatively and effectively” isn’t a charade, it’s to get you thinking in groups to solve problems. Ultimately, the future of the world is in your hands, and you will have to solve many problems with others to maintain a working planet. (By working planet, I mean a planet able to carry out natural resources, countries that work together, jobs for everyone, etc.)
