Lung cancer is a silent and deadly disease. According to the World Health Organization (WHO) survey, the highest number of lung cancer deaths worldwide in 2012, totaling around 159 million people. One of the reasons why this is so high is because early lung cancer is very difficult to diagnose. About 40% of lung cancer patients are diagnosed with lung cancer after their condition continues to deteriorate, and one third of them are cancer phase 3 when diagnosed. Here are some of the lung cancer alerts you must not ignore:

Cough for a long time and can’t be cured.

Everyone cough, probably because of a cold or choked by food. However, if you have a cold or have taken medication and still cough, you should ask your doctor to listen to the lungs or take a lungs X-ray.

Pay attention to the type of cough

Chronic cough is usually a symptom of other diseases such as Gastroesophageal reflux disease (GERD), Asthma or Hay fever. However, if the cough changes, for example from dry cough to coughing mucus or blood, you should see a doctor.

shortness of breath if you don’t engage in intense exercise

If you often have shortness of breath or whistles when breathing, it may be a symptom of lung cancer. This may be because the tumor blocks the respiratory tract, or the fluid around the lungs becomes more fluid, squeezed to the lungs, so that your breathing is not smooth. It’s normal to breathe occasionally, and we often ignore this. However, if you feel unable to breathe after climbing stairs, moving debris, or normal activities that have been easier in the past, ask your doctor for help.

Chest pain

Although tumors that grow in the middle of the lungs do not cause pain, specific lung cancer that occurs on the edge of the lungs or on the chest wall may cause pain. Lung cancer can cause pain in the chest, shoulders, or back. When lung cancer causes chest pain, it may be caused by enlarged lymph nodes or metastasis of cancer cells to the chest wall, pleural or ribs.

I can hear my breath.

When the lungs are contracted, blocked, or inflamed, a whistle-like wheezing can be a symptom of many different physical conditions, such as Allergy and asthma. Don’t ignore it! If you continue to breathe, consult a doctor immediately to find out what’s going on, it’s better than your own guessing.

The voice changes

If your voice becomes hoarse after a cold or after a long period of inuse, such as when you wake up. Or hear your voice change, or someone points out that your voice has changed, such as being low, hoarse or piercing, check with a doctor. If the symptoms of hoarseness do not improve after 2 weeks of medication, it is better to check with a doctor as lung cancer tumor may affect the vocal cords and change the voice.

Weight loss

Fast weight loss is never a good thig. Patients with lung cancer often fall rapidly in a short period of time, as cancer cells are consuming all their energy and nutrients. When you don’t change your diet and lifestyle, don’t ignore changes in weight, as this may be a clue to changes in your health.

I feel pain in my bones.

Advanced lung cancer may metastasis to the bone marrow and cause bone pain. Most Bone cancer patients are older people, so they may think that bone pain will disappear with age. Although this is not common, bone pain from lung cancer is usually concentrated on the back, shoulders, arms, or neck. Pain caused by lung cancer is often exacerbated during your rest or at night. Pain is never a good phenomenon, so do not ignore the pain in any part of the body and check it as soon as possible.

A headache that follows the shadow

The pain caused by lung cancer is the most dangerous because it means that cancer may have moved from the lungs to the brain, something you would never want to see. In some cases, lung cancer causes headaches because the tumor compresses to the nerves that pass through the chest, which causes headaches. If the headache cannot be relieved, seek medical assistance immediately.

There are other signs or symptoms that may indicate lung cancer, such as fever, extreme fatigue, difficulty in eating or swallowing, loss of appetite or unusual lumps in the body. It is important to let your doctor know about any changes in your body. If you have a family history of lung cancer, or if you smoke, you may need to do a routine examination and screening, and early diagnosis can significantly improve the survival of lung cancer.
