Lung tumors of ten centimeters may also be benign. Ten centimeters of lung tumor is very large, but not only based on the size to determine whether the tumor is malignant or not, but also may be benign lesions, such as cysts, giant hemangiomas and so on. Tumors are divided into benign and malignant according to their pathological nature. If it is a benign tumor, even if it grows very big, it is not necessarily life-threatening, but timely surgical treatment is recommended.
