Lung cancer is one of the most typical types of cancer worldwide, with stage 4 being its most advanced stage. A stage 4 lung cancer diagnosis can be difficult for patients and their families. Misinformation and myths often add to the confusion and fear. This article aims to clarify misconceptions and answer common patient questions, providing reliable information and support.

What is Stage 4 Lung Cancer?

Stage 4 lung cancer is the most evolved stage of the disease, meaning that cancer has extended beyond the lungs to distant organs such as the liver, bones, brain, or adrenal glands. At this stage, the cancer is no longer confined to one lung or the nearby lymph nodes. The classification into two subtypes helps doctors determine the extent of the disease and the best possible treatment options.

• Stage 4A: In this stage, cancer has spread within the chest and has affected one distant organ. For example, it may spread to the liver, brain, or one side of the bone.
• Stage 4B: This is a more severe form where cancer has spread to multiple organs throughout the body. It can be present in the liver, bones, brain, and even the pleural fluid surrounding the lungs.

Since cancer has spread to different parts of the body at this stage, treatment focuses on controlling the disease, relieving symptoms, and improving the patient's quality of life.

Debunking Myths About Stage 4 Lung Cancer

Myth 1: Stage 4 Lung Cancer is Always a Death Sentence

Fact: While stage 4 lung cancer is severe, it is not an immediate death sentence. Many people assume that a diagnosis of stage 4 lung cancer means there is no hope. However, medical advancements in recent years have led to improved treatments that help patients live longer and with a better quality of life.

• Survival Rates Have Improved: According to the American Cancer Society, the 5-year survival rate for stage 4 lung cancer is around 6%, but this number is gradually increasing with newer treatments. Some patients respond well to targeted therapy or immunotherapy and live for years beyond their initial diagnosis.
• Treatment Advances: Newer therapies, such as targeted therapy and immunotherapy, have significantly extended the lifespan of patients with specific genetic mutations. These treatments attack cancer cells while leaving healthy cells intact, leading to better outcomes.
• Palliative Care for Symptom Management: Even if a cure is impossible, palliative care helps patients manage pain, breathing difficulties, and other symptoms, ensuring a better quality of life.

Myth 2: Treatment is Useless at Stage 4

Fact: While stage 4 lung cancer is not curable, treatment can significantly improve survival and quality of life. Many patients believe that there is no point in undergoing treatment once they reach this stage. However, this is not true.

• Chemotherapy and targeted Therapy help shrink tumours and slow the progression of the disease. Targeted therapies work on specific genetic mutations in cancer cells, directing to more personalized and effective treatments.
• Immunotherapy: Drugs like Keytruda (pembrolizumab) and Opdivo (nivolumab) have successfully extended survival in many patients. Immunotherapy enables the immune system recognize and fight cancer cells more effectively.
• Radiation Therapy: This can be used to relieve symptoms such as pain, difficulty breathing, or bone pain caused by cancer spreading to other areas.

Many patients live for several years with stage 4 lung cancer by following a combination of these treatments. It is essential to consult an oncologist to determine the most useful treatment plan based on the individual's condition.

Myth 3: Only Smokers Get Lung Cancer

Fact: Smoking is a leading risk factor for lung cancer, but non-smokers can also develop the disease. Many people believe that lung cancer only affects smokers, but research shows that 10-20% of lung cancer cases occur in individuals who have never smoked.

• Genetic Mutations: Some individuals develop lung cancer due to inherited genetic mutations that make them additional susceptible to the disease.
• Environmental Exposure: Exposure to air pollution, secondhand smoke, radon gas, or workplace chemicals (such as asbestos and arsenic) can raise the risk of lung cancer.
• Lung Cancer in Women: Studies show that non-smoking women are more likely to generate lung cancer compared to non-smoking men. Researchers are still studying the possible reasons behind this trend.

Even if a person has never smoked, they should not ignore lung cancer symptoms such as a persistent cough, chest pain, or shortness of breath. Early detection plays a vital role in managing the disease.

Myth 4: Alternative Therapies Can Cure Stage 4 Lung Cancer

Fact: Alternative therapies like herbal treatments, special diets, or home remedies cannot cure lung cancer. While some alternative therapies may help relieve symptoms and improve well-being, they should never be used as a substitute for medical treatment.

• Lack of Scientific Evidence: There is no scientific proof that herbal medicines or special diets can shrink tumours or stop lung cancer progression. Relying only on these methods can lead to delayed treatment and worsen the condition.
• Complementary Therapies Can Help: Some complementary therapies, such as acupuncture, meditation, yoga, and massage therapy, can help manage symptoms like pain, stress, and fatigue. However, these should be used alongside standard medical treatment, not as a replacement.
• Discuss With Your Doctor: If you are considering herbal supplements or alternative treatments, always consult your doctor. Some herbs and supplements may interfere with chemotherapy, immunotherapy, or other prescribed medications.
