Benign tumors are non-cancerous growths that do not spread to other parts of the body. They tend to grow slowly and are usually localized, meaning they stay in one place. Benign tumors are typically not life-threatening, although they can cause problems if they press against nearby organs or tissues.
Malignant tumors, on the other hand, are cancerous growths that can invade nearby tissues and spread to other parts of the body through a process called metastasis. They grow rapidly and can be life-threatening if not treated. Malignant tumors can invade surrounding tissues, damage organs, and interfere with the body's normal functioning. They require immediate medical attention and treatment.
