What phase of the cell cycle should be stoped before being cancerous

A cancer cell can develop during any part of interphase. A cancer cell is a cell that goes through the cell cycle continuously, never stopping in G0.

ancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.
