 4 symptoms of lung cancer that you should be aware of

One particular type of cancer that starts in the lungs is lung cancer. Your lungs are two pliable organs in your chest that allow you to breathe in oxygen and exhaust carbon dioxide.

The most common type of cancer that leads to death is lung cancer.

Lung cancer can strike anyone, although smokers are at a higher risk than nonsmokers. With time and cigarette consumption, the risk of lung cancer rises. Even after many years of smoking, you can greatly lower your risk of developing lung cancer by quitting.


In its initial stages, lung cancer often exhibits no signs or symptoms. Lung cancer symptoms and signs often appear when the condition is advanced.

Lung cancer symptoms and signs can include:

  •  Cough that persists
  • Coughing up blood, even a little bit of it
  • Breathing difficulties
  • Pain in the chest
  • Hoarseness
  • Loose pounds without exerting any effort
  • Bone discomfort
  • Headache

When to consult a doctor

If you experience any recurring signs or symptoms that alarm you, schedule a visit with your physician.

Schedule a visit with your doctor if you have tried to stop smoking but have been unsuccessful. The use of counseling, drugs, and nicotine replacement products are just a few of the quit-smoking aids your doctor may suggest.

The overwhelming majority of lung cancers are brought on by smoking, in both smokers and non-smokers. However, lung cancer can also develop in those who have never smoked or been exposed to secondhand smoke for an extended period. Lung cancer in certain situations might not have an obvious etiology.

How smoking causes cancer of the lungs

According to medical professionals, smoking harms the cells that line the lungs, which in turn leads to lung cancer. Changes in the lung tissue start happening practically immediately after inhaling cigarette smoke, which is full of cancer-causing agents (carcinogens).

Your body might initially be able to repair this harm. However, the healthy cells that line your lungs get more and more destroyed with each subsequent exposure. Damage over time causes cells to behave abnormally, and cancer may eventually manifest.

Types of cancer of the lungs

Based on how lung cancer cells appear when examined under a microscope, doctors categorize the disease into two main categories. Based on the primary lung cancer kind you have, your doctor will decide how to treat you.

The following are the two primary types of lung cancer:

  • Small cell lung cancer: Compared to non-small cell lung cancer, small cell lung cancer nearly exclusively affects heavy smokers.
  • Non-small cell lung cancer: Several different kinds of lung cancer fall under the general category of non-small cell lung cancer. Adenocarcinoma, big cell carcinoma, and squamous cell carcinoma are non-small cell lung malignancies.

Risk factors

Your risk of developing lung cancer could be affected by a variety of variables. For instance, quitting smoking is one way to reduce some risk factors. Other elements, like your family history, are uncontrollable.

The risk factors for lung cancer are as follows:

  • Smoking: As you smoke more cigarettes per day and for longer periods of time, your risk of developing lung cancer rises. Smoking cessation can greatly reduce your risk of lung cancer at any age.
  • Secondhand smoke exposure: If you are exposed to secondhand smoke, your risk of developing lung cancer rises even if you don't smoke.
  • Earlier radiation therapy: You may be more likely to get lung cancer if you've had radiation therapy to the chest for another type of cancer.
  • Radon gas exposure: The uranium in soil, rocks, and water naturally breaks down to form radon, which eventually finds its way into the air you breathe. Any structure, including residences, can build up dangerous levels of radon.
  • Exposure to toxins like asbestos: Your risk of acquiring lung cancer can increase if you are exposed to asbestos at work as well as other carcinogens including arsenic, chromium, and nickel. This risk is especially high if you smoke.
  • Lung cancer in the family history: A person's risk of developing lung cancer is higher if they have a parent, sibling, or kid who has the condition.

Lung cancer consequences may include:

  • Respiratory difficulty: If lung cancer spreads to the main airways, the patient may develop breathing difficulties. Additionally, fluid can build up around the lungs as a result of lung cancer, making it more difficult for the affected lung to fully inflate during inhalation.
  • Gushing blood: Hemoptysis, a condition when you cough up blood (bleeding in the airway), can be brought on by lung cancer. In some cases, bleeding might get really bad. Bleeding can be controlled using some medications.
  • Pain: Pain can result from advanced lung cancer that has spread to the lung's lining or to another part of the body, including the bone. If you have pain, let your doctor know because there are various therapies available to reduce it.
  • Chest fluid (pleural effusion): The pleural space, which surrounds the diseased lung in the chest cavity, may become clogged with fluid as a result of lung cancer.
  • Breathlessness may result from fluid building up in the chest. There are methods to drain the fluid from your chest and lower the possibility of recurrent pleural effusion.
  • Metastasis, the spread of cancer to various organ systems: There is a high likelihood that lung cancer will spread (metastasize) to the bones and brain.

Depending on which organ is damaged and the stage of cancer, pain, nausea, headaches, and other signs and symptoms may be experienced. Generally speaking, lung cancer cannot be cured once it has spread outside the lungs. There are treatments that can help you live longer while reducing indications and symptoms.


Although there is no guaranteed strategy to avoid lung cancer, you can lower your risk by:

  • Avoid smoking: Never start smoking if you haven't already. Talk to your kids about quitting so they can learn how to avoid this significant lung cancer risk factor. Talk to your kids about the risks of smoking when they are young so they will be prepared to handle peer pressure.
  • Give up smoking: Quit smoking right away. Even if you've been a smoker for a long time, quitting lowers your chance of lung cancer. Consult your doctor for advice on effective methods and cessation assistance. Options include drugs, support groups, and nicotine replacement therapies.
  • Refrain from consuming tobacco: Insist that the smoker you live or work with gives up smoking. Request that they smoke outside, at the very least. Avoid places where people smoke, such as pubs and restaurants, and opt for smoke-free establishments instead.
  • Take a radon test at home: Check your home's radon levels, particularly if you reside in a region where radon is known to be an issue. To make your house safer, high radon levels can be reduced. Get in touch with your neighborhood's public health office or an American Lung Association branch for further information about radon testing.
  • Stay away from carcinogens at work: Take care to shield yourself from workplace exposure to hazardous chemicals. Observe the safety recommendations of your workplace. Wear a face mask that has been provided to you as protection, for instance, at all times. What else can you do to safeguard yourself at work? Ask your doctor. If you smoke, you run a higher chance of developing lung cancer from your job's toxins.
  • Eat a diet rich in fruits and vegetables: Pick a nutritious diet rich in various fruits and vegetables. Vitamins and other nutrients are best found in food sources. Large vitamin dosages may be dangerous; therefore, avoid taking them. For instance, scientists supplemented heavy smokers with beta carotene in an effort to lower their risk of lung cancer. As a result, smokers' risk of developing cancer increased, according to the findings.
  • Exercise on most of your days of the week: Start out cautiously if you don't typically exercise. The majority of the week tries to exercise.
