What is a malignant Tumor?

A malignant tumor is what doctors call cancer. It occurs when cells in the body start growing uncontrollably due to damage in their genetic material, often from aging, environmental exposures, or random errors during cell division. What makes it dangerous is that it can invade and destroy nearby healthy tissue, and it can also break away and travel through the blood or lymph system to other parts of the body, where it can form new growths and interfere with vital organs. This ability to spread is why malignant tumors are treated seriously and typically require aggressive treatment such as surgery, chemotherapy, or radiation to stop their growth and prevent them from threatening the patient’s health.
