You have 20 pack years or less and quit a year ago what are your chances of getting lung cancer?

Your risk of getting lung cancer depends on several factors, including the number of pack-years you smoked, your age when you quit smoking, and your overall health.

Pack-years are a measure of how much you smoked over time. One pack-year is equal to smoking one pack of cigarettes per day for one year. So, if you smoked two packs of cigarettes per day for 10 years, you would have 20 pack-years.

The more pack-years you smoked, the higher your risk of getting lung cancer. However, quitting smoking at any age can significantly reduce your risk.

According to the American Cancer Society, people who quit smoking before the age of 40 have a 90% lower risk of getting lung cancer than those who continue to smoke. And even if you quit smoking after the age of 40, you can still reduce your risk of lung cancer by up to 50%.

In addition to the number of pack-years you smoked and your age when you quit, your overall health can also affect your risk of lung cancer. People with certain health conditions, such as chronic obstructive pulmonary disease (COPD) or emphysema, are at higher risk of lung cancer.

If you are concerned about your risk of lung cancer, talk to your doctor. They can help you determine your individual risk and recommend ways to reduce it.
