I have been learning about cancer and what I have learned is a lot. I discovered how cancer begins and how many types of cancer are there. Also how many people have it and that it is very common.
Cancer begins when one of our cells begin to grow or multiply too much It is a tumor, it's bad when it puts pressure on nearby tissue, like the brain. Also it is very common and there are 8 main types of cancers. They are breast, lung, leukemia, prostate, colon, lymphoma, and skin cancers are the most common.
Nearly 1.7 million people have cancer right now. Cancer can be treated very well for many people. Cancer is one of the leading causes of death in the world. The deadliest cancers are lung, breast, colon, pancreatic, and prostate. Cancer has been around since the 1800s.
