An inoperable brain tumor is a tumor located near an essential structure of the brain or positioned so that the surgeon cannot safely gain access to it, according to Cancer.Net. Doctors recommend alternative treatments for inoperable tumors.
Treatment options other than traditional surgery depend on a number of factors. These include the patient's condition, the tumor's type and size and whether it is affecting crucial parts of the brain or has spread elsewhere in the body, states Cancer.Net. One alternative is stereotactic laser ablation. This minimally-invasive process uses MRI, a fiber-optic probe and laser technology to focus heat on the tumor while preserving neighboring healthy tissue, according to Barnes Jewish Hospital.
