About Lesson

Introduction to Cancer:

Cancer is a broad term used to describe a group of diseases characterized by the abnormal growth and spread of cells. These cells have lost their ability to control their growth and division, leading to the formation of tumors or abnormal masses of tissue.

Characteristics of Cancer Cells:

  1. Uncontrolled Growth: Cancer cells divide and multiply rapidly, forming tumors that can invade nearby tissues and organs.

  2. Invasion and Metastasis: Cancer cells have the ability to invade nearby tissues and spread to other parts of the body through the bloodstream or lymphatic system, a process known as metastasis.

  3. Abnormal Cell Structure: Under a microscope, cancer cells appear different from normal cells in terms of size, shape, and organization.

Types of Cancer:

Cancer can affect any part of the body and is classified based on the type of cells where it originates. Some common types of cancer include:

  1. Carcinomas: Arising from epithelial cells that line the surfaces of organs and tissues (e.g., breast, lung, colon cancer).

  2. Sarcomas: Developing in connective tissues such as bone, cartilage, fat, and muscle.

  3. Leukemias: Originating in blood-forming tissues like the bone marrow and causing abnormal blood cell production.

  4. Lymphomas: Affecting the lymphatic system, including lymph nodes and lymphoid tissues.


  1. What is cancer?

    • A. A normal growth of cells
    • B. An abnormal growth of cells
    • C. A bacterial infection
    • D. A viral infection

    Answer: B. An abnormal growth of cells

  2. Which term describes the spread of cancer cells to distant parts of the body?

    • A. Inflammation
    • B. Metastasis
    • C. Remission
    • D. Proliferation

    Answer: B. Metastasis

Case Study:

Emily, a 45-year-old woman, discovered a lump in her breast during a routine self-examination. She went to her doctor for further evaluation, and a biopsy confirmed the presence of cancerous cells. Further tests revealed that the cancer had not spread to other parts of her body. Emily’s treatment plan included surgery to remove the tumor, followed by chemotherapy and radiation therapy.
