Precancerous

Precancerous lesions are abnormal growths or alterations in cells that, if not treated, have the potential to progress to cancer. These lesions are frequently identified during routine screenings or exams and can arise in a variety of bodily areas, including the skin, cervix, colon, and oesophagus.
Precancerous lesions are not cancerous, but they do signal an increased chance of developing cancer over time. Early detection and care are critical in preventing the progression of these lesions to aggressive malignancy. For instance, a Pap screen can detect cervical dysplasia, which can lead to cervical cancer treatment. Similarly, doctors may remove polyps found during colonoscopies to prevent colorectal cancer.
Lifestyle factors such as smoking, poor diet, prolonged sun exposure, and hereditary predispositions frequently cause precancerous lesions. Environmental exposures and chronic infections, such as HPV (human papillomavirus), are also known causes.
Treatment options for precancerous lesions include surgical removal, cryotherapy (freezing), laser therapy, or topical medicines. Regular follow-up and monitoring are crucial to detect any potential development early. Preventive treatments, such as vaccinations and lifestyle changes, can also reduce the likelihood of developing these lesions.
