Textbook Question

Cancer is the same asa. all tumors.b. all neoplasms.c. all malignant neoplasms.c. benign tumors.d. hyperplasia.

Verified step by step guidance

Understand the definition of cancer: Cancer refers to a group of diseases characterized by uncontrolled cell growth and the potential to invade or spread to other parts of the body.

Differentiate between tumors and neoplasms: A tumor is a mass of tissue that's formed by an accumulation of abnormal cells. A neoplasm is a new and abnormal growth of tissue in some part of the body, especially as a characteristic of cancer.

Distinguish between benign and malignant: Benign tumors are non-cancerous and do not spread to other parts of the body, whereas malignant tumors are cancerous and can invade nearby tissues and spread to other parts of the body.

Clarify the term hyperplasia: Hyperplasia is an increase in the number of cells in an organ or tissue, which may lead to its enlargement. It is not synonymous with cancer.

Identify the correct option: Cancer is specifically associated with malignant neoplasms, which are capable of spreading and causing harm.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Cancer

Cancer refers specifically to malignant neoplasms, which are characterized by uncontrolled cell growth that can invade surrounding tissues and spread to other parts of the body. Unlike benign tumors, which do not spread and are generally not life-threatening, cancerous cells can lead to serious health complications and require aggressive treatment.

Neoplasms

Neoplasms are abnormal growths of tissue that can be classified as benign or malignant. While all cancers are neoplasms, not all neoplasms are cancerous. Benign neoplasms do not invade nearby tissues or metastasize, whereas malignant neoplasms, or cancers, have the potential to do so, making the distinction crucial in medical diagnosis and treatment.

Tumors

Tumors are lumps or masses of tissue that arise from abnormal cell growth. They can be classified as benign (non-cancerous) or malignant (cancerous). Understanding the difference between these types is essential, as benign tumors typically do not pose a significant health risk, while malignant tumors can lead to cancer and require more intensive medical intervention.
