Quizplus · Accepted Answer

Stress can activate the autonomic nervous system, which releases hormones known as catecholamines. These hormones can stimulate the growth and proliferation of tumor cells by binding to beta-adrenergic receptors on cancer cells. This can lead to an increase in the size and aggressiveness of tumors.
