What may occur if the cells of the immune system act more slowly?

When the cells of the immune system act more slowly, it can lead to a diminished ability to detect and eliminate cancerous cells. The immune system is crucial for identifying and destroying abnormal cell growths. If the immune response is sluggish, it may allow cancer cells to proliferate, leading to the development of tumors.

Cancer can arise when the body's surveillance system, primarily the immune system, fails to keep abnormal cells in check, which can happen if immune cells are not responding effectively or in a timely manner. This underscores the importance of a robust and responsive immune function in preventing the onset of various types of cancer. Other options, such as menopause, regulatory issues with sugar levels, or urinary retention, do not directly relate to immune system activity in the same critical manner as cancer does.
