I've heard that a lot of people get cancer, but I'm not sure how to protect myself from it.

You should be aware that there are many different types of cancer and they can affect different parts of your body. It's important to understand the symptoms of cancer so you can take action if you think you may have it. If you notice any unusual lumps or bumps on your skin, see your doctor immediately. Other signs include persistent coughing, fatigue, weight loss, and difficulty eating or digesting food.
