We all fear cancer. And there is a good reason for that – in some cases, only early diagnosis may give us hope that a fight with a tumor will be successful. However, we are often confused for detecting the early signs of cancer. After all, there are many types of cancer out there, with different ways of development and cancer symptoms. Should we just give up then and wait for our fate? Not at all. While some early signs of cancer may be hard to spot, others are quite visible, and once we learn them, we may have a higher chance of an early diagnosis.
