It depends on where they are and how long they have been there, not enough info to answer correctly.

Tumor growth depends on the expression of oncogenes, when some unexpected environmental chemical imbalance.
This expression of oncogenes leads to the nonstop division of cells thats through mitosis. As mitosis is just a part of cell cycle, in tumour cells the G1 S G2 phases are rapidly accomplished, even G1 and G2 are skipped in the process. So the more the cells are in the divisional phase quicker the growth of tumour.

The tumor with 5% of the cells undergoing the mitosis stage of the cell cycle is growing faster.
Mitosis divides one nucleus into two identical nucleus so the cell can divide.

more cells in the mitosis cycle = more cells dividing = tumour grows more rapidly
