How long does it take for a brain tumor to go from early to late?

Brain tumor from early to late to how long, mainly depends on how fast the tumor growth. Because the brain is so big, is a bony structure. If the tumor growth is very slow, 10-20 years old is not much, from early to late may be 10 or 20 years. If the brain tumor grows very vigorously, it may grow very large in a few months, which will cause the brain to show symptoms of high intracranial pressure and brain cell destruction. From early to late, the time is very short, so the speed of tumor growth determines how long the tumor has from early to late.
