Can tumor be cured?

Grade I brain tumors may be cured if they are completely removed by surgery. Grade II — The tumor cells grow and spread more slowly than grade III and IV tumor cells. They may spread into nearby tissue and may recur (come back). Some tumors may become a higher-grade tumor.

Does a tumor hurt?

The primary ways that cancer itself can cause pain include: Compression. As a tumor grows it can compress adjacent nerves and organs, resulting in pain. If a tumor spreads to the spine, it can cause pain by pressing on the nerves of the spinal cord (spinal cord compression).
