Affecting both men and women, lung cancer is the second most common cancer
(discounting skin cancer) and a leading cause of cancer death in both
sexes according to the American Cancer Society. The good news: Many lung
cancers can be prevented since they are related to smoking, second-hand
smoke, and sometimes, radon exposure or other environmental factors.
There is no doubt that lung cancer can be a serious disease. However, those
with lung cancer found at an early stage can be treated successfully.
While signs and symptoms may not occur at an early stage, being proactive
and knowing the risk factors can help you, and your doctor, determine if a
lung cancer screening is needed.
Symptoms of Lung Cancer
Most lung cancers do not cause any symptoms until it spreads, but some
individuals who are in the early stages may experience symptoms. The key
is to alert your doctor to any symptoms you have early on, when treatment
may be more effective.
Symptoms may include:
Persistent cough
Hoarseness
Weight loss and loss of appetite
Coughing up blood or discolored (“rusty”) sputum
Chest pain that worsens with coughing, deep breathing or laughing
Shortness of breath
Weakness or tired feeling
New episodes of wheezing
Persistent infections such as bronchitis or pneumonia
Risk Factors and Prevention
Smoking
Exposure to second-hand smoke
Exposure to radon
Exposure to asbestos and other types of chemicals and carcinogens
Family history of lung cancer
Prevention, then, may mean avoiding the items listed above (except family
history, which cannot be controlled). For those individuals at a higher
risk for lung cancer, a test called a Low-Dose CT scan, becoming known
as the "mammogram" of lung cancer testing, available at the
Independence Health System Lung Center.
Types of Lung Cancer
Understanding the different types of lung cancer can help guide treatment
decisions and outcomes. The two main types are non-small cell lung cancer
(NSCLC) and small cell lung cancer (SCLC).
Non-Small Cell Lung Cancer (NSCLC)
NSCLC is the most common type of lung cancer. It tends to grow and spread
more slowly than small cell lung cancer. Subtypes include:
Adenocarcinoma, which often starts in the outer parts of the lungs and
is more common in people who have never smoked.
Squamous cell carcinoma, typically found in the central parts of the lungs
and more commonly linked to smoking.
Large cell carcinoma, which can appear in any part of the lung and tends
to grow and spread quickly.
Small Cell Lung Cancer (SCLC)
SCLC accounts for fewer lung cancer cases and tends to grow and spread
more rapidly. It is strongly associated with smoking and often discovered
at a more advanced stage.
Each type of lung cancer behaves differently and may require a unique treatment
approach. That’s why early detection and proper diagnosis are so
important.
Take Charge of Your Lung Health
Lung cancer can be a life-altering diagnosis, but early detection and timely
care can make all the difference. Whether you’re experiencing symptoms,
have a history of smoking, or are simply concerned about your risk, don’t
wait to take the next step. Understanding the warning signs, risk factors,
and types of lung cancer is an important part of staying informed and
proactive.
