Lung Cancer – Symptoms of Early and Late Stages

Below are excerpts from Chinese medical experts on how they pick up and notice signs of lung cancer found in patients both in early and late stages.

What are the symptoms of advanced lung cancer?

  • Patients show symptoms of poor appetite and weight loss, because cancer cells need to absorb a lot of nutrients that used to be absorbed by normal human cells. Some patients will become very skinny. With the respiratory function being affected, the patient eats less and less, loses a lot of weight and becomes weaker during cancer progression. The worse the patient’s body condition is, the weaker he is to fight against cancer.
  • The patient has difficulties in breathing because his lung is severely damaged. He can barely fall in sleep at night. The advanced lung cancer is not contagious, however, it stops the patient from resting. When the patient inhales, the air hurts his respiratory organs like a knife and causes severe pain in his lung. Along with the growth of the tumor, there might also be symptoms of nausea and vomit, which brings more physical pain to the patient.

Since we have learnt the fact that advanced lung cancer is not contagious, the families should no worry any more when they are taking care of the patients, and make the patients more confidence with their treatment.

Early Symptoms of Lung Cancer

Lung cancer is very common in people’s life and it is a deadly disease. If we learn more about the early clinical manifestations of lung cancer, we may be able to detect the disease at an early stage, and thus seize the best time for treatment. The sooner the disease is diagnosed, the more positive attitude the patient has, the more likely the disease can be cured.

What are the lung cancer warning signs that you should never ignore?

  1. Low-Grade fever

Patients will have low-grade fever or even ardent fever because cancer cells attack bronchus and cause airway obstruction. The patient will get better after taking medicines, but he will relapse soon.

  1. Coughing up Blood

Clinically speaking nearly 50% of patients with lung cancer have this symptom. If a male smoker aged 40 or above, or anyone who is coughing up phlegm or mucus, especially if it is tinged with blood, he is very likely with lung cancer.

  1. Pain in the chest

Nearly 30% to 40% of patients suffer from generally speaking intermittent but not severe chest pain, which lasts from several minutes to a few hours. When the tumor reaches the pleural, pain will be more intense, regular and continuous. If there is pain at early stage of lung cancer and reappear later, it indicates bad prognosis.

  1. Coughing

At the early stage of lung cancer, there are some untypical symptoms, such as coughing. However, coughing is the most common symptom in lung cancer, shown on approximately two-thirds of patients. It can be mild and dry cough, intense cough, or sometimes with phlegm. For patients with chronic cough, they should be check about lung cancer once the symptoms change, such as if coughing becomes more frequent, or happens at night. Continuous and uncontrollable cough is the most painful symptoms for patients.

The early signs of lung cancer is mentioned above. We hope it is helpful. If you find yourself have lung cancer, we suggest you to see a specialist as soon as possible to guarantee the treatment in time. We wish all the patients a healthy life.

Symptoms of Advanced Lung Cancer and Signs of Dying

  1. Swelling

It is a result of proliferation of malignant cancer cells, and can be touched by hand on the body surface or deep in the body. Cancer will spread to the lymph nodes later and cause swollen lymph nodes. Superficial lymph nodes in the neck or armpit can be examined by hand.

  1. Ulcers

Ulcers are formed when some tissues of skin cancer grow fast and tissue necrosis happens because of a lack of nutrition.

  1. Pain

When you feel pain in the body, it means cancer is at the mid-late stage. Pain is mostly caused by cancer cells. At first, it is dull pain, and gets worse at night. And gradually the pain becomes unbearable and continuous, even medicines can’t help.

Symptoms of Advanced Lung Cancer and Signs of Dying

Like other therioma, 90% of patients with lung cancer are advanced lung cancer. There is few clinical manifestation at the early stage, and two-thirds of patients are in stage Ⅲ or Ⅳ when they first go to see a doctor. 95% of patients are diagnosed by clinical examinations, and the symptoms can be primary tumor, metastatic tumor, constitutional symptom or tumor-associated symptoms.

Symptoms of lung cancer can be:

  • Chest tightness and pain

When chest pleural and wall is invaded by lung cancer, the chest pain will get worse, and it will be more clear and constant than before.

  • Shortness of breath and fever

Shortness of breath can be resulted from pneumonia, atelectasis, malignant pleural effusion, diffuse alveolar lesion and others. Fever is a result of obstructive pneumonia or cancerous toxin. The patient will develop cachexia.

  • Coughing

Mostly it is paroxysmal an irritable cough. Usually there is no phlegm or only a small amount of white mucus. Phlegm occurs when there is secondary infection. If it doesn’t improve after two weeks of anti-inflammatory treatment, you should check the possibility of lung cancer. Besides, if symptoms of chronic cough change, or there are harsh sounds with each breath (stridor), shortness of breath, coughing up phlegm or mucus, especially if it is tinged with blood, one should also be cautious.

Symptoms of Advanced Lung Cancer and Signs of Dying

In recent years the incidence of lung cancer is increasing, and the major group is male smokers over 40 years old who have smoked more than 20 years. So what are the symptoms of lung cancer?

  • Changes in the voice or being hoarse

Hoarse voice can be caused by iaryngopharyngitis, a cold, acute bronchitis, or happens after thyroidectomy, throat surgery, vocal fatigue, smoking or drinking too much. But that kind of hoarse voice can be cured by symptomatic treatment and extra rest. And it is not the case for those caused by lung cancer, thyroid cancer, or laryngocarcinoma.

  • Coughing

Symptoms of lung cancer vary on the difference of the locations and functions it damaged. Given that most of the lung tumor grows on the large bronchi, it is irritating and easy to cause coughing. Approximately half of the patients have irritable cough without phlegm or only a small amount of white mucus. Phlegm occurs when there is secondary infection. If symptoms of chronic cough change, or coughing up phlegm or mucus, especially if it is tinged with blood, you should check the possibility of lung cancer. Or if it doesn’t improve after treatment, one should see a doctor as soon as he can.

  • Coughing up blood

It is a special symptom for lung cancer. In the case of central type carcinoma of lung, this symptom happens at early-mid stage because there are blood vessels in the tumor. Coughing damages the surface and ruptures blood vessels. Usually it is a small amount of blood, occasionally there are more in some cases, and it is repeated, or lasting for a long time.

Symptoms of Advanced Lung Cancer and Signs of Dying

Lung cancer is one of the most terrible one among lung diseases, which has a high incidence rate. Surveys show that there are a lot of people dying of cancer every year. If it is not well controlled, it will probably impede the overall development of human.

Symptoms of Advanced Lung Cancer

  1. Pain

It is also shown on advanced lung cancer. The structure of pleural is very complicated, three fourths of the lung surface are surrounded by chest wall, which is composed of a thin layer of parietal pleural, fat, muscle, ribs and skin. Patients feel pain when any of those parts is invaded by cancer. Thus, most of patients with cancer spreading to the chest have this symptom.

  1. Voice being hoarse

Recurrent laryngeal nerve that controls the vocal function on the left side travels from the neck to the chest, loops under the arch of aorta, and turns upward to the larynx. Therefore, if the tumor invades the left mediastinum and puts pressure on the recurrent laryngeal nerve, it causes a hoarse voice, when there are no other symptoms of a sore throat and upper respiratory tract infection.

  1. Neck or facial swelling

The superior vena cava on the right of mediastinum transfers venous blood from upper limbs, head and neck back to the heart. When the superior vena cava is pressed by the tumor, at first it causes jugular vein distention, and later neck and facial swelling. It needs to be taken care of in time.

  1. Shortness of breath and pleural effusion

Almost every patient with regional spread of tumor feels shortness of breath. And if the lymph glands are blocked by the tumor, tissue fluid from lung and cardiac muscle is blocked and causes pericardial effusion or pleural effusion, which both lead to the shortness of breath.
