Lung cancer does not always cause noticeable symptoms in the early stages, and many people are not diagnosed until the disease is advanced. However, there are a few early signs and symptoms that some people experience.

Read on to learn about the early signs and symptoms of lung cancer and how early screening can help people at high risk for the disease.

Signs It’s Time To Go To The Er For Bronchitis

Beware of a new cough that lasts longer. A cough associated with a cold or respiratory infection will go away within a week or so, but a persistent cough that persists may be a symptom of lung cancer.

Shortness of breath or catching a cold easily are also possible symptoms of lung cancer. If lung cancer blocks or narrows the airways, or if fluid from a lung tumor collects in the chest, breathing changes may occur.

Notice when you feel short of breath or shortness of breath. If you find it difficult to breathe after climbing stairs or performing tasks that are easy for you, do not ignore it.

When your airways become narrowed, blocked, or inflamed, your lungs may make a wheezing or whistling sound when you breathe. There can be several reasons for this, some of which are good and easy to treat.

However, wheezing can also be a symptom of lung cancer, so it’s best to bring it up with your doctor. It is better not to assume that wheezing is caused by asthma or allergies. Have your doctor confirm the cause.

Lung cancer can cause chest, shoulder or back pain. This can happen when coughing or during the day.

When lung cancer causes chest pain, the discomfort may be due to enlarged lymph nodes or metastasis to the chest wall, the lining around the lungs (called the pleura), or the ribs.

Lung cancer that has spread to your bones can cause pain in your back or other parts of your body. Bone pain is often worse at night and worsens with movement.

Pneumonia: Video, Anatomy, Definition & Function

Headaches can sometimes be a sign that lung cancer has metastasized (spread) to the brain. However, not all headaches are associated with brain metastases.

If you notice a noticeable change in your voice, or if someone notices that your voice is deeper, hoarse, or muffled, it’s a good idea to see your doctor.

A common cold can cause hoarseness, but when the symptom persists, it can indicate something more serious.

Hoarseness associated with lung cancer can occur when the tumor affects the nerve that controls the larynx or voice box.

Unexplained weight loss of 10 pounds or more can be caused by many types of cancer, including lung cancer.

When cancer is present, this weight loss can be caused by cancer cells using up energy. It can also be caused by changes in the way your body uses food for energy.

If you have not tried to lose weight, you should not ignore the changes in your weight. This may indicate changes in your health.

However, squamous cell lung cancer is more common in men. The reason it occurs more in men is that squamous cell lung cancer develops mainly in smokers and

Squamous cell lung cancer tumors form directly in the airways. Tumors in lung adenocarcinoma, a type of lung cancer

Often, this difference means that squamous cell lung cancer causes more serious symptoms in the development of the disease than lung adenocarcinoma. So, although men and women have the same symptoms of lung cancer, it is not unusual for men to develop noticeable symptoms sooner.

NOTE: We use the words “women” and “men” here to reflect the terms historically used to refer to the gender of people. But your gender may not match how your body reacts to lung cancer. If you are concerned about the symptoms you are experiencing, talk to your doctor.

Small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC) are the two main types of lung cancer. SCLC is less common than NSCLC, but more aggressive.

Possible Causes And Diagnosis Of A Lung Mass

SCLC usually has no early symptoms, but when it has spread to the lungs or other parts of your body, you may experience:

In advanced stages of lung cancer, the cancer usually metastasizes to the lungs and other organs, such as the bones or brain.

If lung cancer has spread to other organs, you may have problems with your vision if it has spread to your bones, a fracture, or if it has spread to your brain.

Lung cancer can cause certain groups of symptoms known as syndromes. Some of the most common are Horner’s syndrome, superior vena cava syndrome, and paraneoplastic syndrome.

What Causes Lung Pain In The Back?

Tumors in the upper part of the lung, called Pancoast tumors, can cause symptoms by affecting the nerves in your face and eyes. These symptoms are collectively known as Horner’s syndrome.

Tumors in the upper right lung can put pressure on your superior vena cava, a large vein that carries blood from your head and arms to your heart. The pressure can cause blood to pool in the blood vessels.

If you have any of these symptoms, it’s important to talk to your doctor right away because superior vena cava syndrome can be life-threatening.

Some lung cancers produce hormones that spread through the bloodstream to distant organs and tissues, causing problems called paraneoplastic syndromes.

Pneumonitis: Causes, Symptoms, Diagnosis & Treatment

Lung cancer does not always look the same. A terminally ill patient may have some or all of the following symptoms. Common symptoms of the last stage include:

If lung cancer is detected at an early stage, usually without symptoms, it is more likely to be treated successfully.

LDCT scans, which use low amounts of radiation, can help identify atypical areas in the lung that may indicate cancer.

Recommend annual LDCT screening for high-risk people ages 55 to 74 who meet any of the following conditions:

How Does Covid 19 Affect Your Lungs?

It recommends annual screening for adults ages 50 to 80 who have smoked for 20 years or more and have smoked or quit within the past 15 years.

If you are experiencing any of the symptoms associated with lung cancer or if you meet the criteria for high-risk individuals, talk to your doctor about whether LDCT scans are right for you.

About 75 percent of people diagnosed with lung cancer have already reached stage 3 or 4 of the disease. Getting a LDCT screening can be a very helpful measure.

Our experts are constantly monitoring the health and wellness space, and we’ll update our articles as new information becomes available. Pneumonia is inflammation and fluid in your lungs caused by a bacterial, viral, or fungal infection. It makes breathing difficult and can cause fever and cough with yellow, green or bloody mucus. Influenza, COVID-19, and pneumococcal disease are common causes of pneumonia. Treatment depends on the cause and severity of pneumonia.

Pneumonia is an infection of the lungs caused by bacteria, viruses or fungi. Pneumonia causes the lung tissue to swell (inflammation) and may cause fluid or pus to build up in the lungs. Bacterial pneumonia is usually more severe than viral pneumonia, and it often goes away on its own.

Pneumonia can affect one or both lungs. Pneumonia in both of your lungs is called bilateral or bilateral pneumonia.

Pneumonia: Causes, Symptoms, Diagnosis & Treatment

Although all pneumonia is inflammation caused by an infection in your lungs, you may have different symptoms depending on whether the root cause is a virus, bacteria, or fungus.

Bacterial pneumonia is more common and more severe than viral pneumonia. It is more likely to require a hospital stay. Providers treat bacterial pneumonia with antibiotics. Viral pneumonia causes flu-like symptoms and is more likely to resolve on its own. Usually, no specific treatment is needed for viral pneumonia.

We classify pneumonia as community-acquired, hospital-acquired, or ventilator-associated pneumonia based on the pathogen (virus, bacteria, or fungi) that causes it and how it is contracted.

You can get hospital-acquired pneumonia (HAP) for another illness or procedure in a hospital or medical facility. HAP is usually more serious than community-acquired pneumonia because it is often caused by bacteria resistant to methicillin-resistant antibiotics.

Lung Pain: Causes, Treatment, And When To See A Healthcare Provider

You can get HCAP at a long-term care facility (such as a nursing home) or at an outpatient, long-term clinic. Like hospital-acquired pneumonia, it is usually caused by antibiotic-resistant bacteria.

If you need to be on a respirator or breathing machine to help you breathe in the hospital (usually the ICU), you are at risk for ventilator-associated pneumonia (VAP). The same types of bacteria that cause community-acquired pneumonia, as well as drug-resistant types that cause hospital-acquired pneumonia, cause VAP.

Aspiration is when solid food, liquid, spit or vomit gets into the trachea (windpipe) and into your lungs. If you can’t cough them up, your lungs can become infected.
