I quit smoking at 36 years old after 15 pack years. What's my risk of lung cancer?

Difficult to predict: It is good that you are quitting smoking. It takes a while for the body to recover from the damage of tobacco and your risk will be lower due to quitting than it would be otherwise. I wish you the best in your effort to quit use of tobacco. ...Read more

Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more

My parents smoked in the house,half a pack to a pack a day until I was 7. Am I at significant risk of lung cancer? I'm a nonsmoker.

My parents smoked in the house,half a pack to a pack a day until I was 7. Am I at significant risk of lung cancer? I'm a nonsmoker.

Not likely: Many of the harmful effects of tobacco do regress and it is unlikely that you are at greater risk than an average non-smoker. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco or alcohol in any form. Practice safe sex. ...Read more

Does lung cancer cause intermittent fleeting rib pain, or would this be advanced disease?? 25, doc says lungs sound clear, 9 -yr pack hstry

Non-specific: Fleeting chest pains are not specific for lung cancer. It could be caused by a host of other benign reasons like muscle pain, rib pain from strain or inflammation. Pneumonia or pleurisy can also cause it. If you are worried about lung cancer and you are a smoker, check with your doctor about a screening CAT scan of the chest. If it is negative, time to stop smoking! ...Read more

29 yr old w/ 6-7 pack years smoking (quit 1month ago). Had mild but persistent 1-sided chest sensation 1 month (feels more like internal tickle/itch than pain). No other symptoms. Lung cancer likely?

29 yr old w/ 6-7 pack years smoking (quit 1month ago). Had mild but persistent 1-sided chest sensation 1 month (feels more like internal tickle/itch than pain). No other symptoms. Lung cancer likely?

Not likely: but if you want to make sure, you should go see a doctor. More importantly, you may want to stop smoking. That will be a good step to reduce your chance of getting lung cancer in the future. Who wants to be worried about lung cancer every time there is a chest sensation? You are only 29 years old. You have lots of years left to worry. ...Read more

How many years(average) of smoking(half a pack per day) does it take to get lung cancer?

How many years(average) of smoking(half a pack per day) does it take to get lung cancer?

None...: ...Even non-smokers get lung cancer. For people having the genetic machinery to get lung cancer (which isn't everybody), smoking increases the chances of lung cancer by an average of 50-fold. The problem is that we don't yet know what genes make smokers susceptible to cancer. It's best not to roll those dice at all. If you want help stopping, tell your doctor. There are many new options to help. ...Read more

I'm 17 have been smoking for a year and in the last half a year almost two packs a day do I have bigger chances of getting lung cancer?

I'm  17 have been smoking for a year and in the last half a year almost two packs a day do I have bigger chances of getting lung cancer?

Quit Now: Quit NOW, before it's too late. Now the increased risk you have done to your body is largely theoretical (although some might argue some permanent harm has already been done). Keep it up for a few more years and we will be able to tell you more precisely how much you are risking your life. Don't start killing yourself until you are at least out of your teens. When UR older, you'll know better. ...Read more

Lung (Definition)

Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
