Did you have asthma first? how many years did you have a cough and clear x-rays?
Lung cancer typically doesn't cause signs and symptoms in its earliest stages. Signs and symptoms of lung cancer typically occur only when the disease is advanced.
Signs and symptoms of lung cancer may include:
* a new cough that doesn't go away
* changes in a chronic cough or "smoker's cough"
* Coughing up blood, even a small amount
* Shortness of breath
* Chest pain
* Wheezing
* Hoarseness
* Losing weight without trying
* Bone pain
* Headache
When to see a doctor
Make an appointment with your doctor if you have any signs or symptoms that worry you.
If you smoke and want to stop in order to reduce your risk of lung cancer, make an appointment with your doctor. Your doctor can recommend strategies for quitting, such as counseling, medications and nicotine replacement products.
asthma & cancer have no correlation unless you smoke, then you have a higher risk.
A number of factors may increase your risk of lung cancer. some risk factors can be controlled, for instance, by quitting smoking. And other factors can't be controlled, such as your sex. Risk factors for lung cancer include:
* Smoking. Smoking remains the greatest risk factor for lung cancer. Your risk of lung cancer increases with the number of cigarettes you smoke each day and the number of years you have smoked. Quitting at any age can significantly lower your risk of developing lung cancer.
* Exposure to secondhand smoke. even if you don't smoke, your risk of lung cancer increases if you're exposed to secondhand smoke.
* Exposure to radon gas. Radon is produced by the natural breakdown of uranium in soil, rock and water that eventually becomes part of the air you breathe. Unsafe levels of radon can accumulate in any building, including homes. Radon testing can determine whether levels are safe.
* Exposure to asbestos and other chemicals. Workplace exposure to asbestos and other substances known to cause cancer — such as arsenic, chromium, nickel and tar — also can increase your risk of developing lung cancer, especially if you're a smoker.
* Family history of lung cancer. People with a parent, sibling or other first-degree relative with lung cancer have an increased risk of the disease.
* Excessive alcohol use. Drinking more than a moderate amount of alcohol — no more than one drink a day for women or two drinks a day for men — may increase your risk of lung cancer.
* Certain lung diseases. People with certain lung diseases, such as chronic obstructive pulmonary disease, may have an increased risk of lung cancer.
