Does a positive attitude cure cancer?

No. According to the National Cancer Institute, to date there is no convincing scientific evidence that links a person's attitude—positive or negative—to their risk of developing or dying from cancer.

This is important because people with cancer are often told to "stay positive," which can feel like pressure. If you have cancer, it is completely normal to feel sad, angry, or discouraged sometimes, and positive or upbeat at other times. There is no wrong way to feel, and feeling down does not cause cancer or make it worse.

At the same time, attitude is not meaningless. People with a positive attitude may be more likely to stay socially connected and active. Physical activity and emotional support may help you cope with your cancer, even though they are not a cure.

If the emotions of cancer feel like a lot to carry, your healthcare team can point you to support and resources.
