Human: I've heard that if I use a lot of sunscreen I can get skin cancer. Is this true? Assistant: 
It is true that too much sun exposure can increase your risk for skin cancer, and it's important to protect yourself by using sunscreen when you're in the sun. However, there are many other factors besides sun exposure that can contribute to skin cancer, such as genetics, age, gender, and lifestyle choices like smoking and drinking alcohol. So it's important to take precautions against all of these risks to reduce your chances of getting skin cancer.
