Its not me who is experiencing any symptoms, its a friend of mine. She tells me shes coughing up blood, hearing a ringing noise in her ears, and seeing black spots in her vision. I looked it up on Google, and Im getting results for Brain Cancer or lung cancer.
These symptoms are surely alarming. She needs immediate medical attention. A complete clinical exam, chest radiograph and an MRI scan of brain along with routine laboratory investigations should be done. Please see a doctor and discuss it.
