About Lesson


Screening for cancer involves testing individuals who do not have symptoms but may be at increased risk of developing cancer. Screening aims to detect cancer at an early stage when treatment is more effective, thereby reducing morbidity and mortality. This session provides an overview of screening guidelines for various types of cancer.

Key Concepts:

  1. Risk Assessment:

    • Screening guidelines are based on individual risk factors such as age, sex, family history, and personal medical history. Risk assessment helps determine the appropriate screening strategy for each individual.
  2. Benefits and Limitations:

    • While screening can lead to early detection and improved outcomes, it also has limitations such as false-positive results, overdiagnosis, and potential harms from follow-up procedures.
  3. Shared Decision-Making:

    • Shared decision-making between healthcare providers and patients is essential for determining the most appropriate screening approach based on individual preferences, values, and risk factors.

Common Screening Guidelines:

  1. Breast Cancer:

    • Mammography is the primary screening tool for breast cancer in women. The American Cancer Society recommends:
      • Women aged 40 to 44 should have the option to start screening with a mammogram every year.
      • Women aged 45 to 54 should get mammograms every year.
      • Women aged 55 and older can switch to mammograms every two years or continue yearly screening.
      • Screening should continue as long as a woman is in good health and is expected to live 10 more years or longer.
  2. Colorectal Cancer:

    • Several screening tests are available for colorectal cancer, including colonoscopy, fecal immunochemical test (FIT), and stool DNA test. The American Cancer Society recommends:
      • Regular screening starting at age 45 for average-risk adults.
      • Screening options include colonoscopy every 10 years, FIT every year, or stool DNA test every three years.
  3. Cervical Cancer:

    • The Pap test (Pap smear) is used to screen for cervical cancer. The American Cancer Society recommends:
      • Cervical cancer screening starting at age 21.
      • Pap test every three years for women aged 21 to 29.
      • Pap test with HPV testing every five years for women aged 30 to 65.
  4. Lung Cancer:

    • Low-dose computed tomography (LDCT) is used for lung cancer screening in certain high-risk individuals, primarily current or former smokers. The U.S. Preventive Services Task Force (USPSTF) recommends:
      • Annual screening with LDCT for adults aged 50 to 80 years who have a 20 pack-year smoking history and currently smoke or have quit within the past 15 years.

Promoting Adherence to Screening Guidelines:

  1. Educate individuals about the importance of cancer screening and the rationale behind specific guidelines.
  2. Provide resources and tools for assessing individual risk factors and determining appropriate screening intervals.
  3. Address barriers to screening, such as lack of access to healthcare services, financial constraints, and cultural beliefs.
  4. Encourage regular discussions between patients and healthcare providers to review screening options and make informed decisions.

Case Study:

Maria, a 50-year-old woman, was hesitant to undergo mammography screening due to fear of radiation exposure and discomfort. After discussing her concerns with her healthcare provider and learning about the potential benefits of early detection, Maria decided to schedule a mammogram. The screening detected a small tumor in her breast, which was successfully treated with surgery, highlighting the importance of adhering to screening guidelines.


  1. At what age should women typically begin cervical cancer screening with the Pap test?

    • A. Age 18
    • B. Age 21
    • C. Age 30
    • D. Age 40

    Answer: B. Age 21

  2. What screening test is recommended for colorectal cancer screening starting at age 45 for average-risk adults?

    • A. Colonoscopy every 5 years
    • B. Fecal immunochemical test (FIT) every year
    • C. Stool DNA test every 3 years
    • D. Pap test every 3 years

    Answer: B. Fecal immunochemical test (FIT) every year
