What action is often taken when a malignant tumor is identified?

When a malignant tumor is identified, the typical and critical action taken is surgical removal and treatment. This approach is focused on addressing the potential threat posed by the tumor. Malignant tumors are cancerous and can invade surrounding tissues and spread to other parts of the body. Therefore, the primary goal in managing a malignant tumor is to eliminate the cancerous cells, which often involves excising the tumor through surgery.

Following surgery, additional treatments such as chemotherapy or radiation therapy may be recommended to ensure that any remaining cancer cells are targeted and to reduce the risk of recurrence. This integrated treatment strategy is essential because simply monitoring the tumor would allow it to grow and possibly metastasize, posing a greater health risk. Similarly, no action or immediate vaccination is inadequate in the face of a malignant tumor because these approaches do not specifically address the urgent need for intervention and management of cancer.
