Can a Cancer of Unknown Primary Be Prevented?
Cancer of unknown primary (CUP) represents a number of different cancers, so there is no known way to prevent it. Still, certain lifestyle changes may reduce the risk of many types of cancer. This might in turn reduce a person’s risk of CUP.
Smoking is one of the most significant risk factors that a person can control, and is thought to be directly related to deaths from cancer. Quitting or never starting reduces the risk of cancers of many types, including those of unknown primary. Please call us if you need help quitting tobacco. This, and a lot more information about tobacco, can be read online or mailed to you.
Factors linked with body weight, physical activity, and eating patterns are also known to affect the risk for different types of cancers and deaths related to cancer. Staying at a healthy weight throughout life, being physically active, following a healthy eating pattern, and limiting alcohol intake can all help reduce your risk of cancer.
Because the exact type and the origin of a CUP are unknown, it’s not possible to say how any particular case might have been prevented. It is important to realize that many people with cancer have no apparent risk factors, and there’s nothing they could have done to avoid the disease.
