Defining TRPV4 Contribution of Schwann Cells to Oral Cancer Pain

Summary

This is a prospective study involving human participants. Pressure and stretch sensitivity measures between oral cancer patients and healthy subjects will be compared. Pain stimulation will be conducted on the site of the cancer in 40 oral cancer patients, and on the tongue in 40 healthy volunteers, using pressure and stretch sensitivity tests.
