5 Early Warning Signs That Cancer is Growing in Your Body

3. Abnormal breathing

Having shortness of breath or experiencing difficulties when breathing after physical activity can indicate a serious problem. Being out of breath is also common in people with allergies, but if you haven’t had a recent cold or known allergy, you must go visit your doctor as soon as possible.

4. Unexplained weight loss

Although weight loss is what you want, if it is sudden, it might be a sign of a serious problem. Sometimes, unexpected weight loss can indicate lung cancer.

5. Back pain

If you experience deep pain in your bones and joints, and if this pain worsens when sleeping overnight, it might be a sign of lung cancer. Although this is a lesser known sign of lung cancer, it is recommendable to check it out with your doctor.
