What Is Stage 4 Cancer: Symptoms, Detection, and Treatment

June 28, 2023

When confronted with impossible odds, the human spirit emerges triumphant. The deepest darkness is dispelled in these moments of unyielding resolve, and the brightest light of hope shines through. We start our adventure today, exploring the unknown territory of stage 4 lung cancer, a disease that casts a dark shadow over countless lives. However, within this vast ocean of doubt lies a haven of insight and confidence that will equip us to weather the storm.

Let us explore with open hearts, eager to accept the prospect of healing, compassion, and hope, even though the words "stage 4 lung cancer" may first conjure despair and powerlessness. In all the chaos, there is a rich tapestry of stories waiting to be told, stories of perseverance and love demonstrating the tremendous power of the human spirit.

Among both sexes, lung cancer has a higher mortality rate than any other type of cancer, including breast, prostate, and colorectal cancers. It takes a long time to grow and is hard to spot in its early, more treatable phases.

The unchecked multiplication of aberrant cells is the underlying cause of lung cancer, which originates in the lungs. The proliferation of these atypical cells can disrupt regular lung function. The malignant cells might metastasize to other organs and tissues in the body from wherever they first appeared in the lung.

Lung cancer can be divided into two categories:

  • Non-small cell lung cancer (NSCLC): About 85 percent of lung tumors are NSCLC, which develops from the epithelial cells that line internal organs. Adenocarcinoma, squamous cell carcinoma, and large cell carcinoma are all non-small cell lung cancers.
  • Small cell lung cancer (SCLC): 15% of all lung cancers are small cell lung cancers, and this type is strongly linked to cigarette use. Lymph nodes aren't immune to its rapid expansion and dissemination.

In India, about 1.8 million instances of lung cancer were detected between 2014 and 2018. In India, lung cancer ranks third among males and females diagnosed with the disease. As for cancer deaths, it is the number one killer of men and the number two killer of women. People over 40 have a higher incidence of lung cancer diagnosis. Nonetheless, the condition can manifest itself in younger people.

Lung Cancer Symptoms

Symptoms of lung cancer are uncommon in its early stages. Lung cancer symptoms often manifest when the disease has progressed.

Possible lung cancer symptoms include:

  • Breathing, coughing, or laughing might exacerbate chest pain.
  • Ache in the back or the belly
  • An ongoing cough
  • Expelling bloody or rust-colored mucus when you cough
  • Weak or exhausted
  • Expansion around the collarbones or neck abnormally low body weight
  • Wheezing or a hoarse voice
  • Problems breathing
  • Inability to eat Persistent or recurrent respiratory diseases like bronchitis and pneumonia

Is It Time To See A Doctor?

You should see a doctor if you have any concerning symptoms that won't go away.

See a doctor if you have tried to quit smoking several times but remain unsuccessful. Your doctor may suggest methods to help you quit smoking, such as behavioral therapy, prescription drugs, or nicotine replacement products.

Tumors indicative of stage 4 lung cancer may be located in

Hormone production, Bones, both lungs (cancer of the lungs begins typically in just one), Brain, Liver

Types of Stage 4 Lung Cancer

Non-small-cell lung cancer (NSCLC) and small-cell lung cancer (SCLC) are the two most common forms of lung cancer. Over 80% of lung cancer diagnoses are due to NSCLC, which can be classified into 5 stages (from 0 to 4). Many people with NSCLC will find out they have it in stages 3 or 4.

Stages of SCLC, which are significantly less common, are restricted and extensive. Cancer has progressed throughout the body and beyond the lungs in extensive-stage SCLC. This is equivalent to NSCLC stage 4 in the vast majority of instances.

Stage 4 Non-Small Cell Lung Cancer

When doctors discover cancerous growths in locations other than the lungs, they classify the disease as non-small cell lung cancer, stage 4. According to the Indian Cancer Society (ACS), tumor size is irrelevant when determining stage.

Stage 4 NSCLC has two substages:

  • Stage 4A: There is one extrathoracic tumor in a patient with lung cancer.
  • Stage 4B: MLung cancer often spreads to other organs.

If NSCLC cancer cells access the circulatory or lymphatic systems, they can travel to any organ in the body. Brain, bone, liver, lung, and heart linings are common sites for stage 4 NSCLC cancers. The malignancies could spread to the cardiovascular system, the major pulmonary arteries, or the lungs.

According to the CTCA, stage 4B diagnoses are more common than stage 4A diagnoses.

Stage 4 Small Cell Lung Cancer

As previously mentioned, small-cell lung cancer has no true fourth stage. Stage 4 SCLC is equivalent to stage 4 NSCLC due to the spread of malignancy.

The American Society for Clinical Oncology (ASCO) reported that the disease may have spread to lymph nodes, bones or bone marrow, the brain, the pleura, or both lungs in extensive-stage SCLC.

Additionally, doctors may diagnose the patient with extensive-stage SCLC if more than one tumor is located in a lung.

Metastatic (stage 4) lung cancer testing

To detect lung cancer, doctors employ a battery of tests and scans. They can spot early warning indicators of cancer, confirm a diagnosis, and assess the disease's progression.

These tests can help determine if a patient has advanced or metastatic lung cancer:

  • MRI scans produce high-resolution images of the inside of a person's body, allowing doctors to see if the lung cancer has progressed to the brain or spinal cord.
  • Like magnetic resonance imaging (MRI) scans, computed tomography (CT) scans display pictures of the body's interior. They can determine if the lung cancer has progressed to other organs, such as the lymph nodes, adrenal glands, liver, brain, or elsewhere.
  • Positron emission tomography (PET) scans may reveal cancer cell locations. Patients get a little injection of something (radioactive sugar) before a PET scan that is supposed to move around the body. The presence and location of cancer could be determined by the substance's tendency to settle in affected areas.
  • Bone scans are useful for determining if lung cancer has spread to the bones. Like PET scans, these exams include injecting radioactive material that accumulates in bones if they contain cancer cells.
  • Only a biopsy can provide conclusive evidence of a cancer diagnosis. To operate, a pathologist will take a tissue or cell sample and examine it under a microscope for symptoms of malignancy.

Treatments for stage IV lung cancer

Stage IV lung cancer is often difficult to treat. At this point, lung cancer may still spread, and some cancer cells may have survived to produce a recurrence.

As a result, treatment goals are around easing symptoms and slowing cancer progression to increase survival time and quality of life. The treatment strategy will depend on several factors, including the specific form of lung cancer, its progress, the presence or absence of specific gene or protein alterations in the cancer cells, and the patient's general condition.

Although oncologists typically recommend surgery for individuals with earlier-stage lung cancer, it is typically ineffective for those with stage IV lung cancer. The cancer has metastasized, meaning it has moved to other parts of the body.

In stage IV, your cancer has spread throughout your body. Therefore your doctor will likely employ a mix of treatments to combat it. The following may be a part of your treatment plan:

Radiation therapy

Stereotactic body radiation therapy (SBRT) uses high doses of radiation to kill or stop cancer cells. Your doctor may treat isolated metastases in stage IV cancer.


Chemotherapy can decrease or halt tumor growth but won't cure you. Intravenous chemotherapy medications attack cancer cells. Doctors combine this with immunotherapy.


Immunotherapy unlocks your immune system to fight cancer. You may undergo immunotherapy alone or alongside chemotherapy depending on tumor immune expression and metastases.

Ayurvedic therapy

Ayurvedic therapy targets cancer cells through genetic alterations. Ayurveda believes in the life energy "prana" and its conduits, "nadis." Ayurvedic therapy for stage 4 lung cancer restores prana and rejuvenates the body's natural healing power. Ayurveda uses herbs, food, cleansing, and lifestyle changes to balance the body, boost the immune system, and improve general health.

Stage 4 cancer in five prevalent locations

Stage 4 breast cancer

Stage 4 breast cancer has spread to body parts near or far from the breast. Metastatic breast cancer affects bones, brain, lungs, and liver.

Stage 4 lung cancer

The cancer has spread from one lung to another or other organs in stage 4 lung cancer. The adrenal glands, bones, brain, and liver are the most common sites of metastasis for lung cancer.

Stage 4 prostate cancer

The cancer can spread to other body regions even when the prostate is removed. Prostate cancer spreads after initial metastasis in the adrenal glands, liver, bones, and lungs.

Stage 4 colorectal cancer

Colon cancer has metastasized or spread to other organs. The liver, lungs, and bones are typical sites of metastasis for colon cancer.

Stage 4 melanoma

In addition to localized skin and lymph nodes, cancer cells have moved to other lymph nodes, organs, and body parts. Bones, the brain, the liver, and the lungs are all possible locations for metastasized melanoma.

How to Beat Lung Cancer Stage 4

In conclusion, despite the catastrophic effects, there is always hope, even after a diagnosis of stage 4 cancer. Cancer therapy is a field that is always changing because of scientific breakthroughs and the tireless efforts of medical professionals. Early detection increases the likelihood of a successful treatment outcome, and both awareness of the signs and fast medical attention can help.
