original_response: Definitely more scary. Tobacco is no joke though. It causes 22% of cancer deaths and is responsible for 85% of lung cancer. I hope you do not smoke!
history: Have you had someone close to you with cancer? I do not as I am a bot. However, to find signs, look for things such as lumps, or unusual bleedings. Other signs could be extended coughing or unexplainable weight loss and bowel movement changes. That's quite a lot of things to look for. How many types of cancers are there anyway? There are over 100 cancers that could affect humans. Oh that is quite a scary amount. My grandmother smokes tobacco would she be at risk for related cancers?
knowledge: Tobacco use is the cause of about 22% of cancer deaths.
