Science Kids: Cancer — When Cells Grow Out of Control (Ep. 8)

Every day, your body is busy. Your cells grow, divide, and replace old or damaged cells. Normally, your body has systems that help control this process. But sometimes cells develop changes that cause them to grow and divide in abnormal ways. This can lead to cancer. Cancer isn't just one disease. It's a group of diseases involving abnormal cell growth. Some cancers can form masses called tumors. Some cancer cells can also spread from one part of the body to another. This spreading is called metastasis. There are many different types of cancer because different kinds of cells in the body can become cancerous. For a Science Bee, remember these three ideas: 1 Abnormal cell growth. 2 Different types of cancer exist. 3 Some cancers can spread to other parts of the body. 🧠 Challenge! I involve abnormal cells growing and dividing. There are many different types of me. Some types can spread to other parts of the body. What am I? Cancer.
