3 Things To Know About Lung Cancer: Who's at Risk?
According to the Centers for Disease Control, lung cancer is the third most common cancer in the United States and the leading cause of cancer death in both men and women. This type of cancer forms in the tissues of the lungs, most often in the cells that line air passages.
The American Cancer Society estimates about 238,340 new cases of lung cancer will be diagnosed in 2023 and about 127,070 people will die from the disease.
Here are three things to know about lung cancer:
Lung cancer symptoms
Most lung cancers don’t have symptoms until they’ve spread, but sometimes there are symptoms with early lung cancer. It is important to see a doctor immediately if you are experiencing the following:
- Chest pain
- Persistent or worsening cough
- Trouble breathing or shortness of breath
- Coughing up blood
- Extreme exhaustion and fatigue
- Weight loss without diet changes, exercise or other known cause
- Repeated bouts of pneumonia
Who is at risk for lung cancer?
There are several risk factors that may increase your chance of getting lung cancer. These include:
Smokers. Cigarette smoking is the leading preventable cause of death in the United States. Cigarette smoke is linked to almost 90% of lung cancer related deaths.
People who smoke are 15 to 30 times more likely to get lung cancer or die from lung cancer according to the CDC.
People who quit smoking have a lower risk of lung cancer than if they had continued to smoke, but their risk is higher than the risk for people who never smoked. Quitting smoking at any age can lower the risk of lung cancer.
People exposed to secondhand smoke. Children and adults who are exposed to smoke from other people’s tobacco burning products, even briefly, are at a higher risk for lung cancer.
People with a family history of lung cancer. If you or a relative (parents, siblings, children) have had lung cancer, your risk of lung cancer may be higher.
Zero exposure to any form of tobacco is the single greatest thing one can do to reduce the risk of developing cancer.
When are yearly lung cancer screenings recommended?
Catching lung cancer in its earliest stages when it is most treatable is a key to survival. According to the American Society of Clinical Oncology, the cure rate for patients who have small, early-stage lung cancer can be as high as 80%-90%.
Nationally, we have had tremendous success in treating lung cancer and improving the survival rate for patients with lung cancer substantially in recent years. This can be contributed to a combination of early detection with screening and better treatment for systemic disease — diseases that affect the entire body.
If you feel you’re at high risk for possibly developing lung cancer, a screening for early detection will improve lung cancer survival rates. The following people should schedule a yearly screen for early detection of lung cancer:
MD Anderson recommends lung cancer screening if you are age 50-80, are a current smoker (or former smoker who quit in the past 15 years) and have a 20 pack per year smoking history (for example, one pack a day for 20 years or two packs a day for 10 years).
