Lung Cancer: Types, Treatment and Lung Cancer Breath Smell

Lung cancer occurs when there is an uncontrolled proliferation of the lung cells thereby causing tumors to grow. Lung cancer can limit a person’s ability to breathe, and it can spread to other parts of the body.

Lung cancer is the third most common cancer type and the main cause of cancer-related deaths in the United States. It is most common in males, and Black males have a 12% more chance of developing it than white males.

Types of Lung Cancer

Lung cancer is of 2 main types and they are treated very differently.

1. Non-small Cell Lung Cancer (NSCLC)

Like 85% of lung cancers are usually Non-small cell lung cancer (NSCLC). The main subtypes of NSCLC are adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. And they all have similar types of treatment.

  • Squamous cell carcinoma:

This starts in squamous cells, these are flat cells that line the inside of the airways in the lungs. This type of lung cancer is often linked to a history of smoking and tends to be found in the central part of the lungs, near the main airway.

  • Large cell carcinoma:

This type of lung cancer grows and spreads very rapidly, and can appear in any part of the lung and this makes it harder to treat. A subtype of large cell carcinoma is known as large cell neuroendocrine carcinoma.

  • Adenocarcinoma:

This type of lung cancer occurs mainly in people who are smokers or formerly smoked, It starts in the cells that secrete substances such as mucus. It is more common in women than in men, and it is more likely to occur in younger people than other types of lung cancer and usually found in the outer parts of the lung and is more likely to be found before it has spread. People with a type of cancer are usually called adenocarcinoma in situ and they tend to have a better outlook than those with other types of lung cancer.

Non-small cell lung cancer (NSCLC) stages:

The Non- small cell lung cancer occurs in different stages which are;

Stage 1: At this stage, the cancer is found in the lung, but it has not spread outside the lungs yet.

Stage 2: cancer at this stage is found in the lung and the nearby lymph nodes.

Stage 3: The Cancer has spread to lymph nodes on the same and opposite side of the chest or to lymph nodes above the collarbone.

Stage 4: Cancer has spread to both lungs, into the area around the lungs, or even to distant organs.

2. Small cell lung cancer (SCLC)

This is sometimes called oat cell cancer and like 10% to 15% of all lung cancers are SCLC. This type of lung cancer grows and spreads faster than NSCLC. Oftentimes, SCLC has already spread by the time they are diagnosed. It tends to respond well to chemotherapy and radiation therapy since it grows rapidly. Unfortunately, this cancer reoccurs in most people.

Symptoms Of Lung Cancer

Lung cancer doesn’t always cause symptoms in the early stage. However, when early symptoms do occur, they may include;

  1. Shortness of breath,
  2. Chest pain that worsens when you breathe deeply, laugh, or cough.
  3. A lingering or worsening cough
  4. Coughing out blood
  5. Hoarseness
  6. Wheezing
  7. Weakness and fatigue
  8. Loss of appetite and weight loss
  9. Recurrent respiratory infections such as pneumonia or bronchitis.
  10. In the Late-stage you might experience symptoms such as:
  11. Numbness in arms or legs
  12. Jaundice
  13. Drooping of one eyelid and shrunken pupils
  14. Swelling of the face and upper body
  15. Lumps in the neck or collarbone
  16. Bone pain especially in the back, ribs, or hips
  17. Headaches
  18. Dizziness
  19. Balance issues
  20. Lack of perspiration on one side of the face
  21. Shoulder pain.


The primary treatments for lung cancer include surgery to remove the tumor, and chemotherapy and radiation treatments to kill cancer cells. However, the treatment for non-small cell lung cancer (NSCLC) varies from person to person and most times dependent on the stage of your cancer when you were diagnosed. The treatment options for NSCLC by stage typically include:

1. Stage 1 NSCLC: You may need surgery to remove a portion of the lung. Chemotherapy may also be recommended, especially if you’re at high risk of recurrence. Lung cancer tends to be treatable if diagnosed at this stage.

2. Stage 2 NSCLC: Surgery may be needed to remove part of the lungs and Chemotherapy is usually recommended.

3. Stage 3 NSCLC: This may require a combination of chemotherapy, surgery, and radiation treatment.

4. Stage 4 NSCLC: At this stage, the available options include surgery, radiation, chemotherapy, targeted therapy, and immunotherapy.

Lung Cancer Breath Smell

Bad breath, also called halitosis and most of the time caused by something in your mouth, throat, or even as a result of lung cancer. Lung cancer produces chemicals that cause bad breath. Which may cause your Breath to smell like rotten foods like garbage or dead animals.

Lung cancer has its own distinct bad breath which consists of a particular combination of gases. This exhaled breath contains volatile and non-volatile organic compounds which are end-products of metabolic processes and the composition of such compounds varies between healthy subjects and subjects with lung cancer.


Lung cancer is a very serious type of cancer, but an early diagnosis often gets you a good chance of survival. Therefore undergoing regular screening can help detect lung cancer at an early stage and enable you to go for treatment before it spreads.
