Are there benign and malignant types of cancer?

Cancer is not classified as benign or malignant—cancer specifically refers to malignant tumors. All lesions diagnosed as cancer are malignant by nature, characterized by rapid growth, easy metastasis, and destruction of surrounding tissues, which fundamentally distinguishes them from benign tumors in both nature and severity. If you notice any abnormal lumps or tissue overgrowth in the body, it is recommended to seek medical evaluation promptly.

In medical terminology, tumor classification is clear-cut: benign tumors are not called cancer. Examples include fibroadenoma of the breast and uterine fibroids, which grow slowly, do not metastasize, and are usually curable through surgical removal. In contrast, the term "cancer" specifically refers to malignant tumors originating from epithelial tissues, such as lung cancer and gastric cancer. Cancer cells proliferate uncontrollably and may spread to other organs via the bloodstream or lymphatic system, posing a serious threat to life.

Distinguishing cancer into benign and malignant types is a conceptual misconception. Such misunderstanding may lead to misjudgment of the condition and delay in treatment. In clinical diagnosis, physicians use pathological examinations to determine the nature of a tumor. Once cancer is confirmed, a standardized anti-cancer treatment plan—including surgery, radiotherapy, chemotherapy, or other therapies—should be established promptly to control disease progression and improve patient survival rates.

Maintaining a healthy lifestyle is essential, including avoiding tobacco, limiting alcohol intake, eating a balanced diet, exercising regularly, and undergoing routine health check-ups. Individuals with a family history of cancer should pay particular attention to screening for relevant organs, aiming for early detection and early intervention.
