👉 Carcinoid is a type of tumor that develops in the brain due to damage from certain substances, such as tobacco smoke. It's characterized by tumors that are typically found in the pituitary gland (the gland that controls sex and hunger signals in the brain). Carcinoids can cause various symptoms, including weight loss, depression, headaches, nausea, vomiting, and difficulty sleeping. Treatment options depend on the type of cancer and its stage.
