Question

Quizplus · Accepted Answer

It is normal for people to develop cancerous cells in their lifetime, but most of the time our immune system is able to detect and destroy them before they can cause harm. However, sometimes these cells escape detection and continue to grow and divide, leading to the development of cancer.

Answer: C 
 While it is true that sometimes our immune system is not able to detect and destroy cancerous cells, there are also medical interventions such as chemotherapy and radiation that can target and destroy cancer cells. Additionally, adopting certain healthy behaviors like exercising regularly, eating a balanced diet, and avoiding tobacco and excessive alcohol consumption can help lower our risk of developing cancer.
