Squamous cell cancer starts in flat cells that line surfaces and organs. In the digestive system, it most often affects the esophagus. This cancer is also found in the lungs or skin, but Dr. Rishi Chadha focuses on esophageal cases at GastroDoxs. He offers early detection and expert care in Houston.
Under sedation, Dr. Chadha visually inspects the esophageal lining and takes targeted tissue samples for pathological analysis.
An ultrasound probe on the endoscope determines how deeply the tumor has invaded the esophageal wall and checks nearby lymph nodes.
CT or PET imaging evaluates whether the cancer has spread to lymph nodes or distant organs, which is essential for accurate staging.
Comprehensive blood work reviews overall health, organ function, and eligibility for various treatment options.
