If you have dreamed about hearing someone else have cancer: Think twice before reacting to some people's words, you may want to improve your position or do work that can be carried out from home. Hearing that someone else has cancer in a dream means that you will be happy with the good news from a person you love, and seeing someone who has cancer in real life becomes ill in your dream means that your health problems will increase and you will receive news that you will be upset about, financial and moral unrest and disgrace.
