Final answer:
Cancer cells compete with healthy cells for resources such as nutrients and oxygen by growing uncontrollably and forming tumors, which can 'rob' blood supply and essential resources from normal tissues.
Step-by-step explanation:
The question addresses the competition between cancer cells and healthy cells for resources. The correct answer to the question is A) Yes, cancer cells actively compete with healthy cells for resources. Cancer cells are characterized by uncontrolled growth and division, often forming tumors that consume nutrients and space at the expense of nearby healthy cells. Essential resources like oxygen and nutrients are diverted from normal cells to feed the high metabolic demands of the rapidly proliferating cancer cells. This diversion affects the overall health of an individual, as the cancerous tissues essentially "rob" blood supply and other vital resources from the 'normal' tissues. Furthermore, cancer treatment strategies often target these fast-dividing cells, attempting to disrupt their replication. However, due to the similarities between cancer cells and some rapidly dividing normal cells, there is significant toxicity associated with many anticancer drugs.
