Why did Yu Juan find out late?

There are two main reasons for this. One is that people's health awareness is poor now, and there are no obvious symptoms in the early stage of cancer, which is easy to be ignored, so it was not detected until the middle and late stage; Second, because the current hospital medical technology can only detect cancer cells in the middle and late stages, this result will be caused. The best way to deal with it is to pay more attention to your health at ordinary times, and it is best to do early cancer screening regularly.
