May 22, 2023 — Did you know that cutting-edge research is highlighting the link between severe symptoms asthma And Lung Cancer?
About 25 million Americans suffer from asthma, prof Chronic bronchitis disease This makes The inner lining of your lungs swells. Between 5% and 10% of Americans have this disease severe asthma. Severe asthma is categorized by the need for moderate to high doses of corticosteroids and other long-acting medications. Often, these medications do not control the symptoms of asthma, which people with asthma experience every night and most days of the week.
The inflammation caused by asthma triggers attacks when patients inhale allergens such as pollen, dust, or pollutants.
Lung Cancer due to inflammation in the respiratory tract, which may contribute to the development of tumors.
“Inflammation appears to be associated with malignancy,” said William Dahut, chief scientific officer of the American Cancer Society. “Inflammation from asthma may be one of the reasons why people with asthma are more likely to develop lung cancer.”
Severe asthma is also characterized by: fibrouscells that can do more Promote inflammation. Researchers Fibroblasts are also linked to lung cancer.
“in Basic laboratory studyResearchers have found that invasive bronchial fibroblasts derived from patients with asthma can activate lung cancer cells. Yi Guo, Ph.D, associate professor of health outcomes and biomedical informatics at the University of Florida College of Medicine in Gainesville. “More studies are needed to explore this relationship in real-world patient cohorts.” (Guo also co-authored a New study Which found that asthmatics are about one and a half times more likely to develop cancer than those in good respiratory health.)
Researchers It was found in the United Arab Emirates that patients with severe asthma are often diagnosed with lung cancer after its development over a period of 3 decades. This is important because it shows that inflammation caused by severe asthma may contribute to long-term damage to lung tissue. The study authors are working with Canadian researchers It was further found that patients with severe asthma are more likely to develop aggressive stage III or IV lung cancer, and that clinicians may wish to consider severe asthma as an indicator of risk for the disease.
Read on to take a look at the things that can put people with severe asthma at risk of developing lung cancer, as well as how to lower those chances.
What are the symptoms of acute asthma?
the Asthma symptoms:
- shortness of breath
- tightness in your chest;
People with severe asthma may also breathe rapidly, have heart rate changes, and may strain their head and neck muscles from the pressure of coughing or trying to get more air.
What are the symptoms of lung cancer?
there Two types of lung cancer. Adenocarcinoma occurs in up to 85% of patients and is also associated with a subtype called squamous cell carcinoma of the lung. Small cell lung cancer, which affects only 15% of patients, grows and spreads faster. For patients with severe asthma, “the increased lung cancer risk does not occur in adenocarcinomas, but is more common in small cell and squamous cell,” Dahut said.
Symptoms of lung cancer include:
- A worsening or persistent cough
- shortness of breath
- coughing up blood
- extreme tiredness
- Unexplained weight loss
Some symptoms of lung cancer overlap with signs of severe asthma. It is important for people with severe asthma to tell their doctor of anything new that is of concern.
Should you be screened for lung cancer if you have severe asthma?
At this time, the Recommendations Screening for lung cancer applies to patients who:
- You have a history of smoking 20 packs or more, and
- smoke now, or have quit within the past 15 years, and
- They are between 50 and 80 years old
However, the risks can be very specific, so it is important that people do what is right for them on an individual level.
“It is important that you stick to what your doctor recommends,” he said. Albert Rizzo, MDChief Medical Officer of the American Lung Association. “If you have a family history of lung cancer, it’s also important to review that with your doctor.”
How can you reduce your risk of lung cancer if you have severe asthma?
To reduce the risk, it is important:
- Stay on top of your symptoms. researchers in Norway I recently discovered that patients with lung cancer symptoms that are only partially controlled have a higher risk of developing lung cancer. If the symptoms of asthma are well controlled, there is a much lower chance of lung tissue damage.
- Ask about adjusting your medications.
Some studies also showed that patients who used inhalers glucocorticoids; Reduce the risk of lung cancer,” Dahut said. (glucocorticoids not only fight inflammation in severe asthma, but also Also in cancer.)
- Do not smoke and avoid all types of secondhand smoke.
- Make your living space safer.
Get your home tested radonwhich can increase the risk of lung cancer,” said Rizzo.
- Avoid carcinogenic chemicals in your workplace. diesel fumesFor example, it has been linked to an increased risk of lung cancer. Avoid exposure to them while you’re on the move, too, by rolling up your windows in traffic.
- Eat more fruits and vegetables. contain these foods powerful compounds It can have a protective effect. Broccoli, cauliflower, cabbage, bok choy, and Brussels sprouts contain sulforaphane, which can reduce the risk of cancer. Leafy greens are full of folic acid, which can also help prevent disease. Plus, consider the color orange: Foods of this color, such as oranges, tangerines, peaches, papayas, red bell peppers, and carrots, contain beta-cryptoxanthin, a pigment known to fight cancer.
- Exercise as often as you can. Ask your doctor to recommend low-impact exercises that don’t cause shortness of breath.
“The more you can control your risk factors for lung cancer, the lower your odds will be,” said Rizzo. In short: There’s a lot you can start doing today to live a longer, healthier life.
