It takes several years after thyroid cancer surgery to pass the critical period

Thyroid cancer is a malignant tumor that originates from the thyroid follicular epithelium or parafollicular epithelial cells. The critical period for thyroid cancer is generally 5 years after surgery.

Thyroid cancer is the fastest growing solid malignant tumor and one of the more common malignant tumors in the head and neck. It may be related to factors such as oncogenes, ionizing radiation, or iodine intake. Cancer cells can be removed through surgery, but studies have shown that most tumors have a higher risk of recurrence and metastasis in the first five years after surgery. A very small number of patients will relapse after five years. Usually, when patients do not show signs of recurrence within five years, they may have passed the critical period.

Although there are no signs of recurrence within 5 years, we should not relax our vigilance. We should go to the hospital for regular physical examinations in the later stage to monitor the development of cancer at all times. After surgery, we should also carry out consolidation treatment based on the recovery of the body to prevent the recurrence of the disease. During treatment, it is recommended that patients maintain a happy mood and do not put too much psychological pressure on themselves, because the survival period after thyroid cancer surgery will also be affected by factors such as emotions and mentality. Once there are signs of recurrence, it is recommended to go to the hospital for treatment in time.
