### input:
I am a 27 year old female. I have been diagnosed with Ankylosing Spondylitis and Cushing s syndrome. I, also, suffer from severe nerve damage that has caused debilitating pain from my waist down and my entire skin organ. I was on Humaira for 7 months before an abundance of infection occurred and the medication was discontinued. I have smoked for 10 years. With my pain management treatment, excessive smowing (2+ packs per day) has became a lifestyle for me. For about 2 months now, I have suffered from everyou symptom of throat cancer besides there being a lump in my throat. I have an ENT appointment tomorrow for an ear injury and continuous ear pain. Terrified, as my health is already bad, I fear throat cancer is an inevitable truth for my appointment tomorrow. My question: What are the chances of it being visible?
