There is a clear distinction between tumors and cancer. Tumors are divided into benign tumors and malignant tumors, while cancer is the general term for malignant tumors.

1. Benign tumors

Benign tumors grow relatively slowly, feel mobile when touched, have clear boundaries, and do not metastasize. The prognosis is generally favorable with surgical treatment. Although there may be local compression symptoms, they typically do not cause systemic symptoms or lead to death.

2. Malignant Tumors (Cancer)

Malignant tumors grow rapidly and exhibit invasive growth, adhering to surrounding mucosal tissues. They do not move when touched, have unclear boundaries, and are prone to metastasis.

Even after treatment, recurrence may occur. Symptoms can include poor appetite, weight loss, and, in advanced stages, emaciation, anemia, and fever. Without timely treatment, death may result.
