They're formed when cells divide and grow excessively, and they can be benign (not cancerous) or malignant (cancerous).</p> <p>A cancerous tumor (malignant neoplasm) can grow unchecked, invade healthy tissue and metastasize (spread), or spread from the place where it starts to other parts of the body. If it goes untreated and continues to spread, a malignant neoplasm can interfere with organ function and become life threatening.</p> <p>Treatment depends on the type of cancer and how far it has progressed. If the cancer is limited to one area and hasn't spread, the tumor may be removed through surgery. Other common treatments include <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/chemotherapy.html/">chemotherapy</a>, which kills cancer cells throughout the body, and <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/radiation.html/">radiation therapy</a>, which kills cancer cells in a specific area of the body.</p> <h3>Keep in Mind</h3> <p>The sooner a malignant neoplasm is detected, the more effectively it can be treated, so early diagnosis is important. Many types of cancer can be cured. Treatment for other types can allow people to live for many years with cancer.</p> <p><em>All A to Z dictionary entries are regularly reviewed by KidsHealth medical experts.</em></p>
