Lymphology Association of North America (LANA) Practice Exam

Which of the following statements regarding breast cancer (BrCA) and the development of lymphedema is true?

1. BrCA survivors should never enter a strength training program in an attempt to prevent lymphedema.

2. All are true.

3. BrCA patients are encouraged to wear a strong compression garment from Day 1 after surgery to prevent the development of lymphedema.

4. BrCA survivors who are obese have a higher risk of developing lymphedema.

The correct answer is: BrCA survivors who are obese have a higher risk of developing lymphedema.

The statement indicating that breast cancer survivors who are obese have a higher risk of developing lymphedema is supported by several studies and clinical observations. Obesity can contribute to the risk of lymphedema in various ways. Increased body weight may lead to additional stress on the lymphatic system and can exacerbate any existing lymphatic dysfunction following breast cancer treatment, such as surgery or radiation. Additionally, obesity is associated with systemic inflammation, which may further complicate lymphatic function. Therefore, maintaining a healthy weight is often recommended for breast cancer survivors as a measure to mitigate the risk of lymphedema and improve overall health outcomes. The other statements do not accurately reflect current understanding and best practices in managing breast cancer and lymphedema. For instance, it is not true that breast cancer survivors should never engage in a strength training program; in fact, carefully supervised strength training may be beneficial and is often encouraged. The use of compression garments is also nuanced and not universally recommended from Day 1 after surgery, as the timing and type of compression should be tailored to the individual’s condition and treatment plan.
