Lung cancer develops when abnormal cells in the lungs grow uncontrollably. Treatment has advanced considerably in recent years, particularly with the development of targeted therapies and immunotherapies that can be highly effective for certain tumors.
Many people with lung cancer also explore nutrition, supplements, herbs, breathing exercises, and other natural or complementary approaches. These strategies may help support strength, nutrition, symptom management, and quality of life, but no natural remedy has been proven to cure lung cancer or replace established cancer treatment.
Lung cancer is broadly divided into two major categories: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC).
Non-small cell lung cancer accounts for most lung cancers and includes adenocarcinoma, squamous cell carcinoma, and large cell carcinoma.
Small cell lung cancer is less common but generally grows and spreads more rapidly.
The distinction is important because these cancers can respond differently to surgery, chemotherapy, radiation, targeted therapy, and immunotherapy.
Lung cancer may not produce obvious symptoms during its early stages. When symptoms develop, they can include:
These symptoms can have many causes other than cancer. However, persistent respiratory symptoms, unexplained weight loss, or coughing up blood should be medically evaluated.
Tobacco smoking is the leading risk factor for lung cancer, but people who have never smoked can also develop the disease.
Other risk factors include secondhand smoke, radon exposure, occupational exposure to substances such as asbestos and certain industrial chemicals, air pollution, previous radiation to the chest, and genetic factors.
A lung cancer diagnosis should never be assumed to mean that someone smoked.
Evaluation may include CT scans, PET scans, bronchoscopy, needle biopsy, or other procedures to determine whether a suspicious lung abnormality is cancerous and whether the cancer has spread.
A tissue sample is particularly important because modern lung cancer treatment increasingly depends on the specific characteristics of the tumor rather than simply its location in the lung.
One of the most important advances in lung cancer care has been identifying molecular changes that drive the growth of individual tumors.
Depending on the cancer type and stage, tumor testing may look for alterations involving genes or proteins such as EGFR, ALK, ROS1, BRAF, KRAS, MET, RET, NTRK, HER2, and others.
Testing for PD-L1 and other biomarkers can also help determine whether immunotherapy may be appropriate.
This testing can sometimes reveal a treatment specifically designed to target a vulnerability in the cancer cells.
Treatment depends on whether the cancer is non-small cell or small cell, how far it has spread, molecular test results, and the person's overall health.
Surgery can potentially cure some early-stage non-small cell lung cancers when the tumor can be completely removed.
Depending on the size and location of the tumor, surgery may remove a small section of lung, an entire lobe, or occasionally an entire lung.
Radiation may be used alone or in combination with surgery, chemotherapy, or immunotherapy.
Highly focused radiation techniques can sometimes treat small lung tumors in people who cannot undergo surgery and can also be used to control tumors or relieve symptoms in advanced disease.
Chemotherapy remains an important treatment for many lung cancers and may be given before or after surgery or as treatment for advanced disease.
Modern treatment frequently combines chemotherapy with immunotherapy or other medications rather than using chemotherapy alone.
Targeted therapies are designed to interfere with specific molecular abnormalities driving cancer growth.
For tumors with an actionable molecular alteration, an appropriate targeted drug can sometimes produce substantial and sustained responses. This is why comprehensive tumor testing can be especially important in advanced non-small cell lung cancer.
Immunotherapy helps the immune system recognize and attack cancer cells. Immune checkpoint inhibitors have substantially changed the treatment of some lung cancers.
They may be used alone or in combination with chemotherapy or other treatments depending on tumor characteristics and disease stage.
Good nutrition is especially important during lung cancer treatment because cancer, breathing difficulties, surgery, chemotherapy, and other treatments can reduce appetite and contribute to loss of weight and muscle.
The priority during active treatment is often maintaining adequate calories and protein rather than following an extremely restrictive “anticancer” diet.
When appetite is poor, smaller frequent meals and calorie- and protein-dense foods may be easier to manage than large meals.
An oncology dietitian can help when weight loss, swallowing problems, nausea, taste changes, or other treatment effects make eating difficult.
Vegetables, fruits, legumes, whole grains, nuts, seeds, and other minimally processed foods provide fiber, vitamins, minerals, and thousands of naturally occurring plant compounds.
Cruciferous vegetables, berries, garlic, turmeric, green tea, and other foods have attracted particular interest because compounds within them demonstrate antioxidant, anti-inflammatory, or anticancer activity in laboratory studies.
Laboratory activity should not be confused with evidence that eating a particular food or taking a concentrated extract will treat an established lung cancer.
Earth Clinic readers have discussed vitamin C, vitamin D, turmeric, medicinal mushrooms, melatonin, NAC, glutathione, selenium, iodine, MSM, and numerous other supplements during lung cancer treatment.
Some of these substances are being investigated in cancer research, and correcting a genuine nutritional deficiency may be beneficial for overall health.
However, supplements can interact with chemotherapy, radiation, immunotherapy, targeted drugs, anticoagulants, and other medications. High doses should not automatically be assumed to be safer or more effective.
Vitamin D is important for bone, muscle, and immune health, and researchers have investigated relationships between vitamin D status and outcomes in many cancers.
Observational associations do not demonstrate that high-dose vitamin D treats lung cancer. People who are deficient may benefit from correcting that deficiency, with supplementation individualized according to blood levels and other health considerations.
Vitamin C has a long history in complementary cancer care. High-dose intravenous vitamin C is pharmacologically different from taking vitamin C orally because IV administration can produce much higher concentrations in the bloodstream.
Laboratory and early clinical research has generated continued interest in IV vitamin C, but evidence has not established it as a cure for lung cancer. People considering high-dose IV vitamin C should discuss it with their oncology team because medical screening and supervision are important.
Curcumin, a compound found in turmeric, has demonstrated effects on numerous inflammatory and cancer-related pathways in laboratory research.
Human cancer studies remain limited, and curcumin has not been established as a treatment for lung cancer. Concentrated curcumin supplements can also interact with medications.
Medicinal mushrooms and mushroom extracts are used as complementary therapies in several traditional medical systems. Certain mushroom-derived compounds have demonstrated immune-modulating effects and have been studied alongside cancer treatments.
Products differ considerably in species, extraction method, concentration, and quality. Evidence for a particular mushroom product should not be generalized to all mushroom supplements, and these products should not be considered substitutes for cancer treatment.
Fenbendazole is a veterinary antiparasitic drug that has attracted considerable attention online following reports from people with cancer who believe it contributed to their recovery.
Laboratory research has identified biological effects of fenbendazole that could potentially be relevant to cancer, but this does not establish that veterinary fenbendazole safely or effectively treats lung cancer in humans.
Individual reports of tumor shrinkage while using fenbendazole cannot determine what caused the response, particularly when chemotherapy, immunotherapy, radiation, surgery, or other treatments were being used at the same time.
Hydrogen peroxide has been promoted in alternative medicine based partly on theories that increasing oxygen or oxidative stress can destroy cancer cells.
There is no clinical evidence that drinking, inhaling, nebulizing, or injecting hydrogen peroxide cures lung cancer.
Hydrogen peroxide is an oxidizing chemical and can injure tissues. Inhaling or nebulizing it can irritate the respiratory tract, which is particularly concerning for someone whose lungs are already affected by cancer or cancer treatment.
Baking soda and other alkalizing protocols are sometimes promoted based on the observation that the environment surrounding some tumors can be acidic.
This does not mean that drinking sodium bicarbonate can selectively alkalize a lung tumor. The body tightly regulates blood pH, and changing urine pH does not demonstrate that cancer tissue has been alkalized.
Large amounts of sodium bicarbonate can also cause significant sodium and acid-base disturbances.
DMSO and frankincense are also discussed in some Earth Clinic lung cancer reports.
Frankincense contains biologically active compounds that have demonstrated interesting effects in laboratory studies, but clinical evidence does not establish frankincense as a lung cancer treatment.
DMSO readily penetrates biological tissues and can increase absorption of substances applied with it. This property makes unsupervised combinations of DMSO with essential oils or other concentrated substances particularly difficult to evaluate for safety.
Shortness of breath is common in people with lung cancer and can result from the tumor itself, surgery, radiation, infection, fluid around the lung, anemia, chronic lung disease, blood clots, anxiety, or other causes.
Breathing techniques such as pursed-lip breathing may help some people feel more in control of breathlessness. Pulmonary rehabilitation and respiratory therapy may also help selected patients.
New or significantly worsening breathlessness should be medically evaluated rather than treated only with breathing exercises.
Physical activity can help preserve strength, mobility, cardiovascular fitness, and quality of life during and after cancer treatment when exercise is medically appropriate.
The amount of activity needs to be individualized. Walking, gentle resistance training, stretching, or supervised rehabilitation may be appropriate depending on lung function, treatment, fatigue, bone health, and whether cancer has spread to the bones or other organs.
Mindfulness, meditation, relaxation techniques, yoga, tai chi, massage, and acupuncture can play useful supportive roles for some people with cancer.
Research suggests that some of these approaches may help with symptoms such as anxiety, pain, fatigue, nausea, sleep problems, or overall quality of life.
Their value is primarily supportive; evidence that a practice improves symptoms should not be interpreted as evidence that it shrinks lung tumors.
Stopping smoking remains beneficial even after lung cancer has been diagnosed. Continuing tobacco exposure can further damage lung and cardiovascular function and may complicate treatment and recovery.
People who find quitting difficult can ask about medications, nicotine-replacement therapy, counseling, and structured smoking-cessation programs.
Maintaining lung function can become an important part of living with lung cancer.
Depending on the individual, supportive care may include pulmonary rehabilitation, treatment of underlying COPD or asthma, breathing exercises, management of anemia, adequate nutrition, physical activity, and treatment of fluid accumulation or infection when present.
Supplemental oxygen can help people whose blood oxygen levels are genuinely low but is not automatically beneficial simply because someone feels short of breath.
Palliative care is not limited to end-of-life care. It can be provided alongside active cancer treatment to help manage pain, breathlessness, fatigue, appetite problems, sleep difficulties, anxiety, and other symptoms.
Introducing supportive care early can help people maintain comfort and quality of life while they continue cancer treatment.
People with lung cancer should seek prompt medical attention for sudden or severe shortness of breath, coughing up significant amounts of blood, new or severe chest pain, fainting, confusion, new neurological symptoms, high fever during cancer treatment, or other sudden changes in health.
These symptoms should not automatically be attributed to the cancer itself because potentially treatable complications such as infection, blood clots, fluid around the lungs, anemia, or treatment reactions may be responsible.
Earth Clinic has collected personal experiences with complementary and alternative approaches to lung cancer for many years. These reports include fenbendazole, hydrogen peroxide, baking soda, DMSO, frankincense, vitamin C, MSM, dietary changes, herbs, supplements, and multi-remedy protocols.
Some readers report tumor shrinkage, remission, or dramatic improvement while using these approaches. Such experiences can be important to the individuals involved, but they cannot establish that a particular remedy caused the outcome. Many people use several treatments simultaneously, and lung cancers can respond substantially to conventional treatments such as targeted therapy, immunotherapy, chemotherapy, radiation, or surgery.
Specific doses and protocols contained in historical reader posts should not be interpreted as current medical recommendations or as treatments endorsed by Earth Clinic.
If you have used complementary approaches during lung cancer treatment, we invite you to share your experience below. Reports are particularly informative when they include the type and stage of lung cancer, molecular test results when known, conventional treatments received, complementary approaches used, and medically documented changes in the cancer.
