A malignant tumor is a type of cancerous tumor that forms as a result of uncontrolled and abnormal proliferation of cells, can spread to surrounding tissues, and is capable of metastasis. It is used synonymously with cancer. These tumors can be life-threatening if left untreated.<\/p>\n
The most distinctive feature of malignant tumors is that they exhibit invasive growth and can spread to distant organs through the blood or lymphatic system. These tumors grow rapidly, damage surrounding healthy tissues, and may create systemic effects. Therefore, early diagnosis is critical.<\/p>\n
Symptoms of malignant tumors include the sensation of a mass, unexplained weight loss, chronic fatigue, loss of appetite, pain, anemia, and non-healing wounds. Symptoms may vary depending on the location and size of the tumor. Systemic symptoms are commonly observed.<\/p>\n
In the diagnostic process, physical examination, imaging methods (CT, MRI, PET), blood tests, and biopsy are performed. The treatment plan is determined according to the type and stage of the tumor; surgery, chemotherapy, radiotherapy, and targeted therapies are the most commonly used methods.<\/p>\n
