precanceroinen

Precancerous refers to a condition that is not yet cancer but has the potential to become cancerous. These are abnormal changes in cells that are not malignant but are more likely than normal cells to develop into cancer. The term "precancerous" is often used interchangeably with "pre-malignant" or "pre-invasive."

These cellular changes are typically identified through medical screening or diagnostic procedures. For instance, abnormal cells found during a Pap smear may be described as precancerous. Similarly, certain types of polyps in the colon are considered precancerous because they can evolve into colorectal cancer over time. Other examples include actinic keratoses on the skin, which can develop into squamous cell carcinoma, and certain precancerous lesions in the cervix, vagina, or vulva.

The progression from a precancerous state to cancer is not inevitable and can often be prevented or halted. Medical interventions such as surgical removal of the abnormal tissue, cryotherapy, or laser treatment are common methods for addressing precancerous conditions. Regular check-ups and screenings are crucial for detecting precancerous changes early, allowing for timely intervention and potentially preventing the development of invasive cancer. The specific appearance and behavior of precancerous cells vary depending on the type of tissue and the potential cancer.
