A researcher is trying to produce a new cancer drug to be tested on small tumors.The tumor has to be localized in a small area of the body and cannot have metastasized (spread to other areas of the body).Furthermore,this drug must prohibit the signaling from one tumor cell to another tumor cell.Given the above information,this new drug will prohibit

Paracrine signaling occurs between neighboring cells and is important in the communication between cancer cells. By targeting paracrine signaling, the drug can prevent communication between the tumor cells, potentially inhibiting their growth and spread. Autocrine signaling occurs within a single cell, so this would not be affected by a drug designed to prevent signaling between tumor cells. Endocrine signaling occurs through the bloodstream, so it would not be relevant for a drug targeted at localized tumors. Direct physical contact between tumor cells may not be the only means of communication, so this option is less likely to be effective compared to targeting paracrine signaling.
