"tumor"の定義と意味

What is a "tumor?

A tumor is an abnormal growth of cells in the body that forms a lump. Tumors can be benign, meaning they are not cancerous and do not spread to other parts of the body, or malignant, meaning they are cancerous and can spread to nearby tissues and other areas. Tumors can develop in any part of the body and may cause symptoms depending on their size and location, such as pain, swelling, or problems with normal functions. Treatment for tumors depends on their type and location and may include surgery, radiation therapy, chemotherapy, or other medical approaches. Early detection and treatment are important for managing tumors effectively.
