-
Hacking cough
A hacking cough is a dry, forceful cough that is often unproductive. It can be a sign of lung cancer when it is persistent and accompanied by other symptoms such as chest pain or shortness of breath.
-
Coughing up blood
Coughing up blood, also known as hemoptysis, is a more serious symptom that can indicate lung cancer. It occurs when a tumor erodes into a blood vessel and causes bleeding into the airways.
The presence of a persistent cough, especially in individuals with risk factors such as smoking or exposure to secondhand smoke, warrants prompt medical evaluation. Early detection and diagnosis are crucial for improving treatment outcomes and the chances of survival.
Chest pain
Chest pain is a common symptom of lung cancer, occurring in approximately 30-50% of patients. It is often described as a dull, aching pain or discomfort in the chest that may worsen with coughing, laughing, or deep breathing. The pain can range from mild to severe and may be localized to a specific area of the chest or more diffuse.
Chest pain in lung cancer is typically caused by the tumor's invasion or irritation of the pleura, the lining of the lungs and chest cavity. As the tumor grows, it can put pressure on the pleura, causing inflammation and pain. Additionally, the tumor can block or compress the airways, leading to shortness of breath and chest pain.

Fatigue
Fatigue is an overwhelming sense of tiredness and lack of energy that is commonly experienced by individuals with lung cancer. It is distinct from the typical tiredness one may feel after physical exertion or lack of sleep, and it can persist despite rest or sleep. Fatigue in lung cancer is often a result of the cancer itself, its treatments, or a combination of both.
The cancer itself can lead to fatigue through various mechanisms. The presence of a tumor can consume the body's energy resources, leading to a state of exhaustion. Additionally, lung cancer can cause inflammation and the release of certain substances that contribute to fatigue. Moreover, the psychological stress and emotional burden of living with cancer can further exacerbate fatigue.
Treatments for lung cancer, such as chemotherapy and radiation therapy, can also contribute to fatigue. These treatments can damage healthy cells and tissues, leading to a decrease in energy levels. Additionally, the side effects of these treatments, such as nausea, vomiting, and loss of appetite, can further worsen fatigue.
Understanding the connection between fatigue and lung cancer is crucial for several reasons. Firstly, it helps healthcare professionals recognize and address fatigue as an important symptom of lung cancer. Secondly, it empowers individuals with lung cancer and their caregivers with knowledge about this symptom, enabling them to better manage it. Finally, it highlights the need for research into the causes and potential treatments for fatigue in lung cancer, with the aim of improving the quality of life for individuals battling this disease.
Weight Loss
Weight loss is a common symptom of lung cancer, and it can occur for a variety of reasons. In some cases, weight loss may be the first noticeable symptom of the disease.
-
Decreased Appetite
Lung cancer can cause a decrease in appetite, which can lead to weight loss. This may be due to the tumor itself, which can release substances that suppress appetite, or it may be a side effect of cancer treatments, such as chemotherapy or radiation therapy.
-
Increased Metabolism
Lung cancer can also cause an increase in metabolism, which can lead to weight loss. This is because the body is working harder to fight the cancer, and this can require more energy.
-
Malabsorption
Lung cancer can also cause malabsorption, which is a condition in which the body is unable to absorb nutrients from food. This can lead to weight loss, as the body is not getting the nutrients it needs.
-
Cachexia
Cachexia is a condition that is characterized by severe weight loss and muscle wasting. It is often seen in advanced stages of cancer, and it can be a sign that the cancer is progressing.
Weight loss can be a serious problem for people with lung cancer. It can lead to weakness, fatigue, and a decreased quality of life. If you are experiencing weight loss, it is important to talk to your doctor to determine the cause and to get treatment.
Hoarseness
Hoarseness, a symptom of lung cancer, refers to a change in the voice that makes it sound breathy, raspy, or strained. It occurs when there is an irritation or swelling of the vocal cords, which are responsible for producing sound during speech.
-
Vocal Cord Paralysis
Lung cancer can cause paralysis of the vocal cords, leading to hoarseness. This occurs when the tumor presses on or damages the nerves that control the vocal cords.
-
Vocal Cord Swelling
Lung cancer can also cause swelling of the vocal cords, which can lead to hoarseness. This swelling can be caused by inflammation or the presence of a tumor near the vocal cords.
-
Phlegm Production
Lung cancer can cause excessive production of phlegm, which can coat the vocal cords and make them vibrate abnormally, leading to hoarseness.
-
Laryngeal Nerve Damage
In some cases, lung cancer can damage the laryngeal nerve, which controls the muscles of the larynx. This damage can lead to hoarseness, as well as difficulty swallowing and breathing.
Hoarseness can be a sign of lung cancer, especially if it is persistent or accompanied by other symptoms such as a cough, shortness of breath, or chest pain. It is important to see a doctor if you are experiencing hoarseness, particularly if you have risk factors for lung cancer, such as smoking or exposure to secondhand smoke.
Wheezing
Wheezing is a common symptom of lung cancer, occurring when airflow through the airways is obstructed, causing a whistling sound during breathing. It can range in severity from mild to severe and may be continuous or intermittent.
-
Bronchial Obstruction
Lung cancer can cause tumors or masses to grow within the bronchial tubes, partially or completely blocking the airway and leading to wheezing.
-
Inflammation and Swelling
Lung cancer can cause inflammation and swelling of the airways, narrowing the passages and causing wheezing.
-
Mucus Production
Lung cancer can stimulate increased mucus production in the airways, which can obstruct airflow and cause wheezing.
-
Compression of Airways
Lung cancer can cause enlarged lymph nodes or other structures to compress the airways from the outside, leading to wheezing.
Wheezing can be a significant symptom of lung cancer, and its presence, especially in individuals with risk factors such as smoking or exposure to secondhand smoke, warrants prompt medical evaluation. Early detection and diagnosis of lung cancer are crucial for improving treatment outcomes and the chances of survival.
