There are over 100 cancers that could affect humans.
Yes there are over 100 types. Unfortunately for my friend, hers wasn't really caused by anything she did. Was your grandmother a tobacco user?
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?
