Lymphedema is one side effect of breast cancer treatment. Measuring the edematous limb enables monitoring changes in the lymphedema and the effect of treatment. Circumference measurement using a measuring tape is an inexpensive simple method and therefore useful and widespread in clinical practice. Circumference measurement performance varies amongst therapists and lacks uniformity in the literature. To date, the effect of different limb positions on measurement results has not been examined.

Purpose: The purpose of this study is to describe 1) the effect of position on upper limb volume measurement by using circumference measurement and 2) to examine whether the difference between positions are similar in the upper limbs of the same woman, and 3) between groups of women who are in the intensive phase, in the maintenance phase of lymphedema treatment and women without lymphedema

Study design: Analytical cross section study Population: Inclusion criteria: 15 women who have completed breast cancer treatments, with a diagnosis of unilateral arm lymphedema, in the intensive phase of lymphedema treatment; 15 women who have completed breast cancer treatment and are in the maintenance phase of lymph edema treatment and 15 healthy women adjusted in age and BMI. Exclusion criteria: active cancer, cardiovascular disorder, wounds or inflammation in the measured upper limb, and illness with fever.

Research tools: Questionnaire to gather personal details, information about the cancer and the lymphedema. Plastic, retractable measuring tape with an accuracy of 1 mm. Fixed points on the limb are measured according to anatomical landmarks and afterwards the limb volume is calculated using the formula for a truncated cone.

Inclusion Criteria:

• 15 women who have completed breast cancer treatments, with a diagnosis of unilateral arm lymphedema, in the intensive phase of lymphedema treatment;
• 15 women who have completed breast cancer treatment and are in the maintenance phase of lymph edema treatment and
• 15 healthy women adjusted in age and BMI.

Exclusion Criteria:

• active cancer,
• cardiovascular disorder,
• wounds or inflammation in the measured upper limb, and
• illness with fever.
