Final answer:
Gliomas can be either benign or malignant, affecting survival rates and treatment options.
Step-by-step explanation:
Glioma is a type of brain tumor that can be either benign (non-malignant) or malignant. Malignant gliomas are cancerous and can be life-threatening. The survival rate for glioma varies widely depending on several factors, including the type, location, and stage of the tumor, as well as the patient's age and overall health. Treatment options for glioma include surgery, radiation therapy, chemotherapy, or a combination of these. However, some tumors may not be operable without causing additional harm to the brain. In such cases, alternative treatments are considered. Innovations in cancer treatments are improving survival rates for various types, such as breast cancer, non-Hodgkin's lymphoma, and melanoma, which is a rare but serious type of skin cancer. Treatments like cisplatin have shown marked success, as seen in the case of Lance Armstrong, who was cured of metastasized testicular cancer.
