Recognizing Lung Cancer Symptoms

Posted by Ethanngo1636781 on 10 May, 2018

Lung cancer in human

Lung cancer is the second most common cancer in the United States, with more than 220,000 lung tumors diagnosed each year. A persistent cough, shortness of breath, and coughing up blood are the most well-known symptoms of lung cancer, but what are the additional signs of lung cancer for which you should be on the lookout? Read on to learn about further lung cancer symptoms you should be aware of.

Swallowing difficulties

If a tumor in your lung spreads to your esophagus, you may find that it is difficult or painful to swallow. Although changing your diet towards softer foods that are easier to take can ease such problems, you should always get difficulties swallowing checked by your doctor to rule out a serious cause such as lung cancer.


Voice hoarseness

A change in your voice may occur in lung cancer if the tumor presses on the nerve controlling your voice box. Although voice overuse, acid reflux, and environmental irritants can trigger hoarseness, you need a medical assessment to discount lung cancer as a possible cause.


Poor appetite

You may find that you don't feel like eating or you can only manage small portions at meals. Reduced appetite can arise in lung cancer due to taste changes, pain or tumor growth. Eating little and often can help when your appetite is poor, but you need to find out from a medical consultation why you are struggling to eat.


Weight loss

If you are eating less, you tend to lose weight, but a lung tumor can also trigger metabolic changes that lead to weight loss. You should always investigate an unintentional weight loss of more than 10 pounds, so seek medical advice if you have lost a significant amount of weight without trying.



Feeling excessively tired and finding no improvement following rest or extra sleep is a lung cancer warning sign. You experience fatigue in lung cancer due to reduced lung function with tumor growth, but the poor dietary intake and weight loss can also contribute to extreme tiredness. If you can't explain why you feel so tired, you should always book an appointment with your doctor.

While the five symptoms above have multiple causes, you should always get new symptoms checked out, particularly if they occur alongside other worrying signs.
