Introduction

Mouth cancer, also known as oral cancer, is a serious medical condition that affects the mouth and surrounding areas. In the United Arab Emirates (UAE), the prevalence of mouth cancer has been on the rise, making early diagnosis and treatment crucial for better patient outcomes. Traditional diagnostic methods, such as physical examinations and biopsies, are essential but have limitations. Fortunately, modern technology has brought about innovative imaging techniques that are revolutionizing the way mouth cancer is diagnosed in the UAE. In this blog, we will explore these cutting-edge imaging methods and their role in early detection and improved patient care.

Conventional Diagnostic Techniques for Mouth Cancer

Before the advent of innovative imaging techniques, conventional diagnostic methods played a crucial role in identifying mouth cancer. While they have limitations, these techniques have been the foundation of early diagnosis and paved the way for the integration of cutting-edge technologies. Let's delve into these traditional approaches:

1. Physical Examination

The initial step in diagnosing mouth cancer typically involves a comprehensive physical examination by a healthcare professional, often a dentist or oral surgeon. This examination includes:

• Visual Inspection: The healthcare provider visually examines the oral cavity, including the lips, tongue, gums, cheeks, and the back of the throat, looking for any visible abnormalities, such as red or white patches, sores, or lumps.
• Manual Palpation: During palpation, the healthcare provider gently feels the oral tissues for irregularities, such as nodules or indurations (thickened areas).

While physical examination is a fundamental tool for early screening, it has limitations. It primarily relies on visible surface-level changes, which means that early-stage or sub-surface lesions may go undetected.

2. Biopsy

When suspicious lesions or abnormalities are identified during a physical examination, a biopsy is often recommended to confirm the presence of cancer cells. The biopsy procedure involves the following steps:

• Tissue Sampling: A small piece of the abnormal tissue is surgically removed for laboratory analysis.
• Histopathological Examination: The collected tissue sample is then examined by a pathologist under a microscope. This examination helps determine the type and stage of the cancer.

Biopsies are considered the gold standard for cancer diagnosis as they provide definitive evidence of cancerous tissue. However, they are invasive and may cause discomfort to the patient. In some cases, early-stage lesions might not be detected accurately due to the small size of the biopsy sample.

3. Endoscopy

Endoscopy is a diagnostic method that allows for a more in-depth examination of the oral and throat regions. This procedure involves the use of an endoscope, a flexible tube with a camera and light source, which is inserted into the body to provide detailed images. Endoscopy is used to:

• Visualize Internal Structures: It provides a clear view of the throat, larynx, and other internal structures, making it useful for identifying abnormalities or lesions that may not be visible through a standard physical examination.
• Biopsy Guidance: Endoscopy can be used to guide biopsies and collect tissue samples from specific areas within the oral and throat regions.
