Eight years of breast cancer does not mean that it is fine, there is still the possibility of recurrence and metastasis. Clinically, there have been breast cancer patients who still have lung metastasis or bone metastasis more than ten years or even twenty years after surgery, so it is suggested that after eight years of surgery, breast cancer patients should have regular medical checkups, insist on daily adjustments, eat more vegetables and fruits, and exercise appropriately. If breast cancer patients have cough, chest tightness, shortness of breath and other uncomfortable symptoms after surgery, it is recommended to actively go to the hospital to do relevant diagnosis and treatment, and they can check whether there is bone metastasis or lung metastasis through chest CT or whole-body bone scan. After breast cancer surgery, patients should go to the hospital for rechecking regularly to avoid any unexpected situation affecting the recovery of the body.
