The nurse is educating adolescent high school students about when to seek medical attention regarding suspected cancerous skin lesions. Which of the following are included in the nurse's teaching? The lesion has:
An irregular border.
Asymmetrical shape.
Been increasing in size.
A diameter of less than 4 mm.
Ecchymosis.
Correct Answer : A,B,C
A. An irregular border is a key characteristic of potentially cancerous skin lesions, particularly melanoma. Melanomas often have uneven, poorly defined edges.
B. Asymmetry is another sign of melanoma. If one half of a lesion does not match the other in shape or size, it should be evaluated by a healthcare professional.
C. Any lesion that has been increasing in size, particularly over a short period, is a concern and should be checked. Rapid growth can be a sign of malignancy.
D. A lesion with a diameter of less than 4 mm is generally less concerning, as most cancerous lesions are larger. However, the other factors (such as asymmetry and border irregularity) are more significant for diagnosis.
E. Ecchymosis (bruising) is not typically associated with cancerous skin lesions. Skin cancers like melanoma present as new or changing moles, not bruising.

C. A personal history of inflammatory bowel disease, such as ulcerative colitis or Crohn's disease, significantly increases the risk for developing colorectal cancer due to chronic inflammation and cellular changes in the colon.
D. Having a distant relative with colorectal cancer may increase risk, but the personal history of inflammatory bowel disease is a stronger risk factor warranting emphasis in teaching.

A. Using sunscreen while playing sports is an important measure to protect the skin from harmful UV radiation, which contributes to skin cancer; therefore, this statement indicates proper understanding.
B. Monthly self-examinations for suspicious lesions are recommended as part of early detection strategies for skin cancer, demonstrating a proactive approach to skin health.
C. Decreasing the use of a tanning bed to twice a month still poses a significant risk for skin damage and cancer, as tanning beds expose the skin to high levels of UV radiation. This statement indicates a lack of understanding of the dangers associated with artificial tanning.
D. Wearing a hat and sunglasses while in the sun is an effective strategy for minimizing sun exposure to sensitive areas, protecting the skin and eyes from UV rays, indicating proper sun safety practices.
