CIN grade 2 has the possibility of reversal and self-healing, but in different patients, it will show different results. After being detected CIN2, if patients can treat this condition correctly psychologically, develop good habits in daily life, stay away from bad living and eating habits such as smoking, drinking, staying up too late, spicy stimulation and oily food, and insist on physical exercise, and the body’s ability to resist disease is strengthened, there is a possibility of reversal of the CIN2 level. If the patient is not able to treat this result correctly, emotional outbursts, excessive stress, smoking, drinking, staying up all night and other kinds of bad lifestyle, leading to a continuous decline in immune function, then the possibility of reversing the CIN2 level to heal itself is very small, and there is a possibility that it may further develop into a level 3.
