Malignant tumors are cancerous and are the result of abnormal tissue growth in the body. Unlike benign (noncancerous) tumors, malignant tumors are made up of cells that multiply, become uncontrolled, then spread to surrounding parts of the body. They can also move through the body’s blood or lymphatic systems.
The causes of malignant tumors may be environmental, hereditary, linked to specific viruses or other factors that weaken or suppress the immune system, making it more susceptible to disease. Depending on the location and size of the tumor, symptoms may include detection of a lump, unusual weight loss, abnormal bleeding, fever, changes in bowel movements and/or excessive tiredness. Symptoms are sometimes not apparent until the cancer has progressed to a certain stage.
Common treatments are surgery, radiation therapy, and chemotherapy, method combinations, as well as alternative and complementary options.
