The Role of Ultrasound as a Diagnostic Tool for Breast Cancer in the Screening of Younger Women (Age 25-38) in Guyana

Abstract

Objective: Ultrasound is used in many ways, not only as an initial diagnostic tool for confirmation of pathology determined from biopsies of the breast but also staging of breast cancer. Ultrasound is inexpensive and readily available almost all over the country. In a recent publication from the UK, the incidence of breast cancer in women younger than 35 years was 1.4% and in those younger than 30 years it was 0.43%. Breast Cancer is the most commonly diagnosed cancer amongst women worldwide. There were approximately 1.38 million new cases of breast cancer in the year 2008 and by 2020 this figure is anticipated to escalate to 1.7 million. Results: A total of 80 charts were reviewed, with a 95% confidence level and a confidence interval of 9.42. The average age at which women were being screened is 33 from 2010-2016. Ultrasound showed sensitivity was 97% and the specificity 98%. Discussion: Ultrasound was shown to be more sensitive than mammogram. Afro-Guyanese were the majority screened. Most persons had ultrasound done with both malignant and benign diseases being discovered with this modality. The malignant cases were more frequently diagnosed at stage II and the average of detection was 33. Conclusion: Ultrasound is effective and sensitive in the diagnosis of breast cancer. It is also effective in diagnosing benign breast diseases in younger women with dense breast tissue. Ultrasound is cheaper and safer than other imaging modalities for screening and diagnosis.
