Lung Cancer

Lung Cancer: A Silent Threat You Shouldn’t Ignore

Lung cancer is one of the most common—and deadliest—forms of cancer worldwide. In the United States alone, it claims more lives each year than breast, prostate, and colon cancers combined. Despite its prevalence, early symptoms often go unnoticed, making timely diagnosis and treatment absolutely critical.

Lung cancer develops when abnormal cells in the lungs grow uncontrollably, often forming tumors that interfere with breathing and can spread (metastasize) to other parts of the body. Smoking is the leading cause, but it’s not the only risk factor. Non-smokers can—and do—get lung cancer too.

If you’ve been experiencing persistent coughing, chest pain, or unexplained weight loss, board-certified pulmonologist Dr. Michael N. Newton, who serves patients in and around Tampa, Florida, can help you understand what’s going on and guide you toward the right care.

In this blog, Dr. Newton breaks down what you should know about lung cancer—and why awareness and early detection could save your life.

When lung cancer starts to show its signs

In its earliest stages, lung cancer can be surprisingly silent. That’s why it often goes undetected until it’s more advanced. For many patients, the first signs can be subtle—like a cough that just won’t go away or feeling more tired than usual.

Common symptoms of lung cancer include:

• A persistent cough that worsens over time

• Chest pain that’s constant or worsens with deep breathing or coughing

• Shortness of breath

• Wheezing or hoarseness

• Coughing up blood (hemoptysis)

• Frequent lung infections like bronchitis or pneumonia

• Unexplained weight loss and fatigue

Not everyone experiences all these symptoms. That’s why it’s important to talk to a healthcare provider if something feels “off,” especially if you’re at increased risk.

Understanding your lung cancer risk

The most significant risk factor for lung cancer is tobacco use—including cigarettes, cigars, and even secondhand smoke exposure. However, up to 20% of people who die from lung cancer in the U.S. each year are non-smokers.

Other contributing factors include:

• Exposure to radon gas (a naturally occurring radioactive gas)

• Occupational exposure to asbestos or other harmful chemicals

• A family history of lung cancer

• Air pollution

• Previous radiation therapy to the chest

Dr. Newton emphasizes that anyone can develop lung cancer, and knowing your risk can help guide decisions about screening and prevention.

Why early diagnosis is vital

Like many cancers, lung cancer is most treatable in its early stages. Unfortunately, because early symptoms are often vague or misattributed to other conditions, the disease is frequently diagnosed when it’s already advanced.

Early diagnosis can lead to:

• More treatment options

• Better response to therapy

• Improved survival rates

• A higher quality of life

If you’re over 50, have a history of smoking, or fall into a high-risk group, Dr. Newton may recommend low-dose CT (LDCT) screening, which can detect lung cancer before symptoms appear.

Treatment options for lung cancer

Treatment depends on the type of lung cancer (non-small cell vs. small cell), the stage of the disease, and your overall health. Dr. Newton works closely with a multidisciplinary team to create a personalized treatment plan for each patient.

Treatment may include:

• Surgery to remove the tumor or affected lung tissue

• Radiation therapy to target cancer cells directly

• Chemotherapy to destroy cancer cells throughout the body

• Immunotherapy to help your immune system fight the cancer

• Targeted therapy based on specific genetic changes in the tumor

In addition, supportive care and pulmonary rehabilitation can help manage symptoms and maintain lung function during and after treatment.

Supporting your lung health: Lifestyle tips that make a difference

Whether you’re at risk for lung cancer or recovering from it, taking care of your lungs is key. Dr. Newton recommends the following:

• Quit smoking—it's never too late to benefit from stopping

• Test your home for radon, especially if you live in a high-risk area

• Avoid secondhand smoke and industrial pollutants

• Eat a balanced diet rich in antioxidants and whole foods

• Exercise regularly to improve lung capacity and stamina

• Stay up-to-date on vaccines, including flu and pneumonia

Don’t ignore the signs—your lungs are worth protecting.
If you’re concerned about symptoms or want to learn more about lung cancer screening, don’t wait. Early action can save lives.
