Fasting is a common method to try and get rid of cancer cells. Also most people have small numbers of cancer cells and probably mini tumors that can turn into full blown cancers after several decades. And it is likely that killing mini tumors is significantly easier than getting rid of a cancer. So it would make sense to try and get rid of those mini tumors long before they become big.
This is speculation but perhaps dasatinib would be effective against most for of cancer cells if they are relatively easy to kill. Combining Dasatinib with fasting, Quercetin and also perhaps fisetin, which have anti cancer properties, and eating only anti cancer vegetables might be effective at killing mini tumors, besides the effect of getting rid of senescent cells. Other anti cancer supplements could be added like curcumin.
Dasatinib has side effects though so this would have to be looked into. The most important thing it seems would be bleeding, which could be exacerbated by fasting which would tend to thin the blood. Supplements like curcumin might also thin the blood. Adding vitamin K1 rich vegetables or supplements might help with that.
I expect 3 days of fasting on dasatinib to be a rather unpleasant experience, but it could be worth the effort.
Dasatinib is effective not only in leukemia cancers, but also against other forms of cancer:

Again, Dasatinib may be incapable of killing the cancer cells, but it is the synergy that would make it more effective. It's like Quercetin cannot kill senescent cells on its own but with the help of Dasatinib it can.
