Several methods effectively destroy abnormal cells, depending on the type and location of the abnormality. These methods are crucial in treating precancerous conditions and various cancers.
Methods for Destroying Abnormal Cells
-
Laser Therapy: This uses a concentrated beam of light to remove or destroy abnormal tissue. It's a common treatment for abnormal cervical cells, as noted by the National Cancer Institute (https://www.cancer.gov/types/cervical/screening/abnormal-hpv-pap-test-results) and Macmillan Cancer Support (https://www.macmillan.org.uk/cancer-information-and-support/treatments-and-drugs/abnormal-cervical-cells). Also known as laser ablation, it's a precise method for targeting specific areas.
-
Cryotherapy: This involves freezing abnormal cells to destroy them. It's another technique used in treating precancerous and cancerous conditions.
-
Cold Coagulation: Similar to cryotherapy, this method uses cold temperatures to destroy abnormal cells.
-
Large Loop Excision of the Transformation Zone (LLETZ): Also known as loop electrosurgical excision (LEEP) or loop diathermy, this procedure uses a thin wire loop heated with electric current to remove abnormal tissue. This is frequently used for treating abnormal cervical cells (https://www.cancerresearchuk.org/about-cancer/cervical-cancer/abnormal-cervical-cells/treatment-for-abnormal-cervical-cells).
-
Excisional Therapy/Cervical Conization/Cone Biopsy: These procedures surgically remove abnormal tissue. (https://www.uptodate.com/contents/management-of-a-cervical-biopsy-with-precancerous-cells-beyond-the-basics)
-
The Immune System: Importantly, our own immune system plays a vital role. Certain immune cells can recognize and destroy abnormal cells, including cancer cells. (https://www.cancerresearchuk.org/about-cancer/what-is-cancer/body-systems-and-cancer/the-immune-system-and-cancer)
Other Cancer Treatments Targeting Abnormal Cells
While the above focus on directly destroying abnormal cells, other cancer treatments indirectly address them:
- Chemotherapy: Uses drugs to kill rapidly dividing cells, including cancerous ones. (https://www.cancer.gov/about-cancer/treatment/types)
- Radiation Therapy: Uses high-energy radiation to damage DNA in cancer cells, leading to their death. (https://www.cancer.gov/about-cancer/treatment/types)
- Immunotherapy: Boosts the body's immune system to better fight cancer cells. (https://www.cancer.gov/about-cancer/treatment/types)
- Targeted Therapy: Uses drugs that target specific molecules involved in cancer cell growth. (https://www.cancer.gov/about-cancer/treatment/types)
