Cancer-Related Dictionary

Oligodendroglioma is a type of brain tumor arising from oligodendrocytes, cells that produce myelin - an insulating layer around neurons. This slow-growing tumor generally affects adults and is often found in the frontal lobe of the brain. Symptoms include persistent headaches, seizures, and changes in personality or mental capacity. Treatment typically involves surgery, chemotherapy, and radiation therapy.

Oral cancer refers to any cancerous tissue growth located in the mouth. It may arise as a primary lesion originating in any of the oral tissues, by metastasis from a distant site of origin, or by extension from a neighboring anatomic structure, such as the nasal cavity or the maxillary sinus. Early detection significantly increases the chances of a successful treatment.

Osteosarcoma is a type of cancer that originates in the bones. It most commonly affects adolescents and young adults, but can occur at any age. This aggressive malignant neoplasm leads to abnormal, uncontrollable growth of osteoblasts, the cells responsible for bone formation. It predominantly occurs in long bones like the femur, tibia, and humerus, consequently causing pain and swelling in the affected area.

An ovarian germ cell tumor is a type of cancer that originates from the cells in the ovaries responsible for producing eggs. These tumors are rare and primarily affect young women and adolescents. While most ovarian germ cell tumors are benign, some can be malignant and require medical treatment.

Ovarian cancer is a type of cancer that begins in the ovaries, the female reproductive glands that produce eggs or ova. It often goes undetected until it has spread within the pelvis and abdomen, making it difficult to treat and often fatal. Symptoms can include abdominal bloating, discomfort, weight loss, and frequent urination. It is the fifth most common cause of cancer-related death among women.
