Introduction: It is estimated that more than 40% of newly diagnosed breast cancers present with nodal metastasis. The sensitivity of ultrasound-guided FNAC/biopsy to assess axillary nodal metastasis ranges from 28.5 % to 55.6%. There is an overlap in the appearance of benign/reactive and malignant nodes. Several studies have been conducted to evaluate a cut off for the ALNCT and there have been some variations in millimetres from one Centre/study to another, ranging from 2.0mm to 3.0mm.Method:HRA approval was obtained.The ALNCT of the most prominent node was measured at right angles to the plane of the cortical margin using GE Logic E9 or Philips IU22. 170 patients aged 20 and over with U1 and U2 findings are recruited to the study over a period of three months. SPSS version24 was employed for statistical analyses. Age was sub-grouped according to 5 rationales to determine the 50th and 90th percentiles.Result: The study revealed a negative correlation of ALNCT with increasing age, supported by a ‘p' value of 0.001 and Pearson's -0.42. Patients under 55 years of age had a 50th and 90th percentile of 2.2mm and 2.9mm, respectively. In over 54-year-old patients, it was found to be 1.7mm and 2.2mm, respectively.Conclusion: The negative correlation between ALNCT and age is significant enough to prompt a review of the current practice. It is proposed that ages may be divided into under 55 years and above. The researcher proposes a cut off of 2.6mm for <55 and 2.2mm for >54years.
