Pathologists are now able to examine many tumors under the microscope and divide tumors into high-grade tumors, which have a 70-90% chance of having spread, and low-grade tumors, where the chance of spread is low (less than 15%).
Does radiation therapy help with high grade tumors?
The addition of chemotherapy for the highest-grade tumors reduces the rate at which high-grade tumors return and may improve the rate of cure. The use of specialized radiation therapy techniques has significantly reduced the likelihood of tumors coming back at the site where they have been removed. Often, depending on the type of tumor, preoperative radiation therapy or chemotherapy (or a combination of the two) may be used to make some of these tumors more easily resected with adequate margins.
