Précancéreuse

Pré-cancéreuse refers to abnormal cells that are not yet cancerous but have the potential to become so. These cellular changes are often identified through medical screenings and are considered a precancerous condition. The term is commonly used interchangeably with dysplasia, neoplasia, or intraepithelial lesion, depending on the specific tissue and type of abnormality.

The development of precancerous cells is a gradual process that typically involves genetic mutations within cells. These mutations can accumulate over time due to various factors, including exposure to carcinogens, chronic inflammation, infections, or hormonal imbalances. While not all precancerous lesions progress to cancer, they represent an increased risk.

The detection of precancerous conditions is crucial for early intervention and prevention of cancer. Medical professionals use diagnostic tools such as biopsies, colposcopies, and imaging tests to identify and assess these abnormal cells. Treatment strategies aim to remove or manage the precancerous tissue to prevent it from evolving into invasive cancer. The specific approach depends on the location, size, and grade of the lesion. Regular follow-up examinations are often recommended after treatment to monitor for any recurrence or the development of new precancerous changes.
