Breathing difficulties can result from many conditions, but they may also signal lung cancer or cancers that affect the chest.

Symptoms may include:

Difficulty catching your breath
Wheezing
Chest tightness
Reduced ability to exercise
Shortness of breath that develops gradually or worsens over time should not be ignored.

Persistent Headaches
Most headaches are not related to cancer. However, headaches that become increasingly severe, occur more frequently, or are accompanied by neurological symptoms may require further evaluation.

Brain tumors can sometimes produce headaches along with:

Vision changes
Nausea
Balance problems
Memory difficulties
Seizures
Medical assessment can help determine the underlying cause.

When to See a Doctor
It is important to remember that many of these symptoms can result from conditions unrelated to cancer. However, the key warning sign is persistence.

Seek medical advice if symptoms:

Last several weeks or longer
Continue to worsen
Have no obvious explanation
Interfere with daily activities
Occur alongside weight loss or fatigue
Healthcare professionals can perform examinations, imaging studies, laboratory tests, and screenings to identify the cause.

Reducing Cancer Risk
Although not all cancers can be prevented, certain lifestyle choices can significantly reduce risk.

Recommended preventive measures include:

Avoid tobacco products
Maintain a healthy weight
Exercise regularly
Eat a balanced diet rich in fruits and vegetables
Limit alcohol consumption
Protect your skin from excessive sun exposure
Receive recommended vaccinations
Participate in age-appropriate cancer screenings
These habits support overall health and may lower the likelihood of developing several types of cancer.
