What we know about Penny Marshall's cancer
According to public reports, Penny Marshall died of lung cancer. This article draws only on publicly reported information — noted in the source below — and focuses on what Penny Marshall's story can teach everyone about lung cancer.
Understanding lung cancer
Lung cancer begins in the cells of the lungs and is one of the leading causes of cancer death worldwide. The two main groups are non-small cell lung cancer (the most common) and small cell lung cancer. Its risk is discussed in our guide to radon.
Signs and symptoms
Early lung cancer often causes no symptoms. When they appear, warning signs can include a cough that does not go away or worsens, chest pain, shortness of breath, hoarseness, coughing up blood, and unexplained weight loss. Learn more about the signs of lung cancer.
Lowering the risk
The single biggest risk factor is tobacco smoke, and not smoking — or quitting — is the most powerful way to lower risk. Avoiding secondhand smoke, testing the home for radon, and limiting workplace exposures such as asbestos also help.
Finding it early
Lung cancer may be found on imaging such as a CT scan and confirmed with a biopsy. For people at high risk from smoking, low-dose CT screening can catch lung cancer earlier, when it is more treatable. See our guide to screening and early detection.
Why stories like this matter
When a public figure shares a cancer diagnosis, it can prompt others to learn the warning signs, talk with their doctor, and take screening seriously. That awareness saves lives — a cancer found early is very often far more treatable.
