Malignant tumors are abnormal growths of cells that can invade nearby tissues and spread to other parts of the body. Unlike benign tumors, which do not spread, malignant tumors can be aggressive and are often associated with cancer. They can develop in various organs, including the lungs, breast, and colon. These tumors can disrupt normal bodily functions and may lead to serious health complications. Treatment options often include surgery, radiation therapy, and chemotherapy, depending on the tumor's type and stage. Early detection is crucial for improving outcomes and increasing the chances of successful treatment.
