What is the typical size of a lung cancer tumor?

The average total lung tumor dimension measures 3 inches in size, as stated by the University of Texas Southwestern Medical Center. Total tumor dimension is a measure that includes both the size of the primary tumor as well as other ones located in various sites of metastatic disease.

Patients with tumors larger than 3 inches had a shorter lifespan compared to those with a smaller tumor in a study that the University of Texas Southwestern Medical Center conducted, as noted by the university. Patients who had total tumor dimensions smaller than 3 inches had a 30 percent greater survival rate.
