TumCCA, Tumor cell cycle arrest: Click to Expand ⟱
Source:
Type:
Tumor cell cycle arrest refers to the process by which cancer cells stop progressing through the cell cycle, which is the series of phases that a cell goes through to divide and replicate. This arrest can occur at various checkpoints in the cell cycle, including the G1, S, G2, and M phases. S, G1, G2, and M are the four phases of mitosis.
