Squamous Cell Carcinoma

Squamous cell carcinoma is a type of cancer that begins in the flat, thin squamous cells that line many surfaces of the body, including the airways of the lungs. In the lungs it's one of the main types of non-small cell lung cancer and is strongly linked to smoking and to asbestos exposure. It often starts in the larger, central airways.

Origin

"Squamous" comes from the Latin squama, meaning scale, describing the flat, scale-like look of these cells under a microscope. "Carcinoma" derives from the Greek karkinos, meaning crab, an ancient term for cancer.

Significance in Asbestos Context

For asbestos patients, squamous cell carcinoma of the lung is one of the cancers that asbestos exposure can cause or contribute to, especially in people who also smoked, since the two exposures multiply the risk. Unlike mesothelioma, lung cancer has other common causes, so proving the asbestos link often relies on exposure history, markers of asbestos disease such as asbestosis or pleural plaques, and expert testimony. A diagnosis backed by evidence of significant asbestos exposure can still support a legal claim even when smoking also played a role.

Example Sentence

My squamous cell carcinoma was blamed on smoking at first, but the pleural plaques on my scans led the doctor to ask about my years insulating boilers.

Notes

• Make sure your doctors and legal team know your full asbestos exposure history even if you smoked.
• Ask whether your imaging shows other signs of asbestos disease, such as pleural plaques or asbestosis, which help link the cancer to exposure.
• Smoking doesn't bar an asbestos claim; the combined risk is well recognized, so preserve your work and medical records.
