Preneoplastic lesions, also referred to as precancerous lesions or premalignant lesions, represent a critical stage in the development of cancer. These lesions are characterized by abnormal tissue changes that may progress to full-blown cancer if left untreated. Understanding preneoplastic lesions is essential for early detection, prevention, and intervention strategies in the fight against cancer [1].

These lesions are often found on sun-exposed skin and are considered precursors to squamous cell carcinoma. They appear as rough, scaly patches and can be an early warning sign of skin cancer. A condition in which the lining of the oesophagus changes, usually due to chronic acid reflux. Barrett's oesophagus can progress to esophageal adenocarcinoma, a type of cancer[2].

Precancerous changes in the cells of the cervix, typically detected through Pap smears. Cervical dysplasia can be caused by human papillomavirus infection and may progress to cervical cancer if not treated. These benign growths in the colon or rectum are considered precursors to colorectal cancer. Regular screening can help detect and remove them before they become cancerous [3].

Changes in lung tissue associated with chronic lung diseases, such as Chronic Obstructive Pulmonary Disease (COPD) that may evolve into lung cancer. White patches in the mouth, often linked to tobacco or alcohol use. Some cases of leucoplakia can develop into oral cancer. Detecting and treating preneoplastic lesions at an early stage can prevent the progression to cancer. For instance, the removal of colorectal adenomas during a colonoscopy can significantly reduce the risk of colorectal cancer. By addressing the underlying causes of preneoplastic lesions, such as HPV vaccination to prevent cervical dysplasia, we can reduce the incidence of certain cancers [4].

Patients with preneoplastic lesions often require regular monitoring to ensure timely intervention if progression to cancer occurs. Identifying preneoplastic lesions can provide valuable information about a person's risk of developing cancer, guiding personalized preventive measures and screening schedules. Preneoplastic lesions serve as crucial indicators in the early detection and prevention of cancer. Timely recognition and management of these precursors are fundamental in reducing the burden of cancer and improving patient outcomes. With advances in medical research and diagnostics, our ability to identify and intervene in preneoplastic lesions has improved, offering hope for a future with fewer cancer diagnoses and better overall health outcomes. Regular screening, lifestyle modifications, and vaccination programs are essential components of our arsenal in the fight against cancer [5].
