Question

Quizplus · Accepted Answer

The stage at which tumors produce substances that encourage the growth of blood vessels to supply energy and other nutrients to the cancerous cells is called progression. During progression, the cancer cells acquire new mutations that allow them to invade nearby tissues and stimulate the growth of blood vessels through the process of angiogenesis. This enables the cancer cells to receive the nutrients and oxygen they need to grow and divide rapidly, contributing to the malignancy of the tumor.
