Detecting cancer early is important to save lives. Cancer can cause many symptoms. And many of these can be the same as other diseases. But there are some key symptoms that are more strongly linked to cancer.
If you develop any of these symptoms, make an appointment right away to see your doctor. It’s important to see your doctor about these symptoms even during the pandemic. They will work with you to decide what tests you need.
