Lung Cancer in Women: Causes, Symptoms, and Early Warning Signs

Lung cancer begins when abnormal DNA mutations cause uncontrolled cell growth in the lungs. These mutations can be triggered by several factors, including:

• Smoking: The leading cause of lung cancer; tobacco smoke contains thousands of carcinogens that damage lung tissue.
• Asbestos Exposure: Inhalation of asbestos fibers increases lung cancer risk.
• Genetics: A family history of lung cancer can make some women more vulnerable.
• Radiation Therapy: Women who have had radiation therapy for other cancers may be at increased risk later in life.
• Radon Gas Exposure: Long-term exposure to high radon levels, a naturally occurring radioactive gas, is a known risk factor.

The general signs of lung cancer in women often overlap with those seen in men and may include:

• Persistent shortness of breath
• Chronic, worsening cough or wheezing
• Coughing up blood
• Chest discomfort or pain
• Difficulty swallowing
• Unexplained weight loss
• Fatigue
• Frequent lung infections (like pneumonia or bronchitis)

However, women may develop different types of lung cancer than men, leading to different symptom patterns. For example:

• Men are more likely to develop lung cancer in the main airways, resulting in more respiratory symptoms like coughing and breathlessness.
• Women often have tumors in peripheral parts of the lungs, which can initially cause fatigue, back pain, or shoulder pain rather than respiratory issues.

Other Rare Conditions

Certain syndromes associated with lung cancer may present with additional symptoms, some of which are more or less common in women:

Horner Syndrome - Caused by damage to nerve pathways between the brain and face, this condition is linked to specific lung tumors and can result in:

• Drooping eyelids
• Constricted pupils
• Facial changes

Superior Vena Cava Syndrome - Occurs when the vein carrying blood from the upper body to the heart is blocked. Symptoms include:

• Swelling of the face, neck, chest, or arms
• Cough
• Breathing difficulties

​Paraneoplastic Syndromes - These occur when the body’s immune system reacts to cancer. Symptoms may include:

• Muscle cramps
• Poor coordination
• Generalized weakness

There are several ways to check for lung cancer. Generally, the sooner it's detected, the more likely any treatment will be successful. Long-term smokers should have regular lung cancer screenings. Lung cancer can be checked in the following ways:

• Imaging tests: Doctors use these to take detailed pictures of the lungs and chest to look for any signs of cancer. These may include X-rays, tomography (CT) scans or positron emission tomography (PET) scans.
• Sputum cytology: Sputum is a type of mucus that is coughed up from the lungs. This test examines the sputum under a microscope to see if any cancer cells are present.
• Thoracentesis: If there's fluid collecting around the lungs, this test will take a sample to check for cancer cells.
• Tissue biopsy: This involves taking a sample of lung tissue and testing it for cancer cells. This is usually done using a thin, hollow needle.

There are several treatment options for lung cancer. Which treatment is best will depend on each patient's circumstances, such as the stage of their cancer, their health, and more. Some common ways to treat lung cancer are as follows:

Chemotherapy - Chemotherapy uses medication to damage and destroy cancer cells. In chemotherapy, these medications travel through the bloodstream and attack cancer cells throughout the body, rather than just a specific area. This makes it a good option for cancer. Chemotherapy drugs used to treat lung cancer include:

• Gemcitabine
• Paclitaxel
• Vinorelbine
• Carboplatin

Chemotherapy is often used in combination with other types of treatment, such as surgery.

Immunotherapy - This treatment uses the body's own immunity to fight cancer. Because cancer often develops from normal cells, the immune system may not recognize it as something it should remove from the body. Immunotherapy solves this by helping the immune system locate cancer, then stop or slow it from spreading.

Radiation therapy - This treatment uses beams of radiation, such as X-rays, to destroy cancer cells. This form of treatment is typically used in conjunction with both chemotherapy and surgery to remove all cancer cells.

Drug therapy - This type of treatment targets key features identified within cancer cells and makes drugs accordingly. By reducing these symptoms, the drugs destroy the cancer. Targeted drug therapy may be used with other treatments, such as chemotherapy, or on its own.

The symptoms of lung cancer in women are similar to those in men. However, some differences may make treatment different for women with lung cancer. Lung cancer is the second most common form of cancer. Women are more likely than men to develop lung cancer that is not related to smoking. Lung cancer in women is a rapidly increasing health problem, caused by abnormal growth of lung cells. Its main cause is smoking, but it is also being found in non-smoking women, which may also be associated with air pollution, passive smoking, genetic factors and hormonal changes. In the early stages, its symptoms are minor, such as persistent cough, shortness of breath, chest pain or hoarseness of voice. Sometimes these symptoms are similar to common diseases like asthma or bronchitis, due to which timely diagnosis is not possible. Timely detection of lung cancer and proper treatment like chemotherapy, radiation or surgery can improve the quality of life. Awareness among women, timely testing and lifestyle modification can reduce the risk.
