The First Signs of Lung Cancer

Lung Cancer

1. Persistent Cough That Doesn’t Go Away

A lingering cough — especially one that lasts more than eight weeks — is one of the earliest signs. It may be dry or produce mucus, and often worsens over time. If your cough sounds different or feels deeper than usual, it’s worth noting.

2. Shortness of Breath During Everyday Tasks

Feeling winded from light activities, like climbing stairs or walking a short distance, can signal changes in lung function. As tumors grow, they may block airways or cause fluid buildup, limiting oxygen intake.

3. Chest Pain or Discomfort

Lung cancer can cause aching or sharp pain in the chest, especially when laughing, coughing, or breathing deeply. This can also be felt in the back or shoulders — and it’s often misattributed to muscle strain or heart issues.

4. Hoarseness or Voice Changes

A noticeable change in your voice — becoming raspier or hoarser — could suggest irritation or pressure on the vocal cords, particularly if it lasts longer than a couple of weeks.

5. Unexplained Weight Loss

Dropping pounds without trying is a common sign of many cancers, including lung cancer. If you notice changes in appetite or consistent weight loss, it may be more than just a diet fluke.

6. Frequent Infections Like Bronchitis or Pneumonia

Recurring respiratory infections may occur if cancer is obstructing airways, making it easier for infections to develop and harder to treat fully.

7. Fatigue That Doesn’t Improve With Rest

Cancer-related fatigue feels different from typical tiredness. It’s deeper and longer lasting — often unaffected by sleep or rest — and can significantly interfere with daily life.

If you or someone you know is experiencing a combination of these symptoms, it's important to consult a healthcare provider. While these signs do not guarantee a cancer diagnosis, early medical attention can make a difference.
