Final answer:
Abnormal cell growth results in the formation of a tumor, which can be benign or malignant. Benign tumors are noncancerous growths that may be removed for comfort, whereas malignant tumors indicate cancer, with problematic growth and potential spread throughout the body.
Step-by-step explanation:
Understanding Abnormal Cell Growth
When discussing the abnormal growth of cells within the body, we often refer to this phenomenon as a tumor. A single mutated cell can multiply, forming a mass that may be benign (noncancerous) or malignant (cancerous). Benign tumors typically do not pose a life-threatening risk and can sometimes be surgically removed for comfort or because of their potential to become malignant. On the other hand, malignant tumors are characterized by their unchecked growth, invasive nature, and the potential to spread or metastasize to other parts of the body, classifying them as cancers.
A disease such as cancer involves this type of abnormal cell proliferation. The malignancy arises from mutations that cause cells to grow and divide uncontrollably, forming a mass that compromises the normal functionality of tissues.
It is important to note that not all neoplasms form solid masses; conditions such as leukemia involve abnormal cell proliferation without the formation of a traditional tumor. Regardless, both benign and malignant growths result from altered cellular mechanisms that affect cell cycle control, for instance, through over-expression of cell division-promoting proteins or failure to regulate proteins that would normally inhibit the process.
