Prekancerøse

Prekancerøse, also known as precancerous conditions or lesions, refers to abnormal cell growth that is not yet cancerous but has the potential to develop into cancer. These changes are detected through microscopic examination of tissue samples. They represent a stage in the progression from normal tissue to malignant disease. Not all precancerous lesions will necessarily become cancerous, but they are monitored closely due to the increased risk.

The development of precancerous conditions is often linked to genetic mutations in cells, which can be caused by various factors including exposure to carcinogens like tobacco smoke or certain viruses. Environmental factors, chronic inflammation, and hormonal influences can also play a role. The specific appearance and location of precancerous lesions vary depending on the type of tissue affected and the underlying cause.

Diagnosis of precancerous conditions typically involves a biopsy, where a small sample of the abnormal tissue is removed and examined by a pathologist. Imaging techniques may also be used to help identify suspicious areas. Treatment strategies depend on the type, size, and location of the precancerous lesion, as well as the individual's risk factors. Options can range from close monitoring to surgical removal of the affected tissue. Early detection and intervention are crucial in preventing the progression to invasive cancer.
