Dumb cane help?!
I would remove it and replant in a pot one size bigger. If you cut the stem and re-pot at the same time, the plant may go into shock and not recover. Put in an area where it will receive indirect light, but not too much. They will survive in low light, but only if healthy. After it is healthy, yes, you can cut it off and it will 'branch'. You can pot up the cutting and have another plant.
Dumb cane is forgiving but it does not need a lot of water. The leaves are looking smaller because the top was cut off and the side shoots are on smaller stems. You can separate those stems and pot them up separately and just leave one shoot.
The loss of the leaf color is probably because it is not getting a lot of light. The leaves will be green in less light and be almost white in full sun or bright light. Remember the more variegated a plant is the more light it requires. Whe you put a variegated plant in low light most of them will revert. Green leaves can do more photosynthesis than white ones.
