Some women may believe that cancer is spreading inside them while they wait for test results. This is an understandable but ungrounded concern. Although prompt action is essential if you suspect breast cancer, the reality is that any cancer that is detectable has existed for some time. It won't change significantly in a few weeks. Women need a doctor who will guide them, who will be encouraging, and provide a good source of information in the right amount, at the right time.
Information has to come at the right time, or it's overwhelming.
But there's a difference between being afraid and letting anxiety escalate until it gets out of control. That doesn't help anyone, not the woman, not her family. Keep reminding yourself that your worst fear is usually much worse than the reality.
