Symptoms of Lung Cancer
Most of the time lung cancer doesn’t show any signs or symptoms early on. Instead, the symptoms usually begin once the cancer has advanced. These symptoms might include:
- Headache
- Bone pain
- Weight Loss (without trying)
- Hoarseness
- Wheezing
- Chest pain
- Shortness of breath
- Coughing up even a small quantity of blood
- Changes to a chronic (or “smoker’s”) cough
- A new cough which won’t go away
Lung Cancer Stages
The term "stage" refers to the amount to which the lung cancer spread within the body. To determine the stage, a doctor will evaluate the size of the Tumor in addition to whether there are metastases within other organs or the lymph nodes. Staging is crucial for determining the ideal treatment for a tumor as well as a patient’s prognosis. Generally speaking, patients with higher-stage tumors will have a worse prognosis compared to those with lower-stage tumors.
Tests to Stage Lung Cancer
Doctors use a combination of tests to stage lung cancer and these include PET scans, bone scans, CT scans, X-rays, and blood tests. Abnormal blood chemistry tests can indicate metastases within the liver or bone. Radiological procedures are also used to determine the size of a tumor in addition to whether it has spread to additional organs.
Non-Small-Cell Lung Cancer
This is the most common type of lung cancer and usually responds differently to various treatments and spreads slower than small-cell lung cancer does. The following chart outlines the stages of non-small-cell lung cancer.
Stages | Description of the Cancer |
Stage 1 | Within stage one, the cancer hasn’t spread to surrounding lymph nodes and remains in the lungs. There are two sub-stages. Stage 1A: The tumor measures less than 1.2 inches (3 cm) in size. |
Stage 1B: The tumor is between 1.2 and 2 inches (3 to 5 cm). | |
Stage 2 | Stage 2A: The tumor is 5 to 7 cm or the tumor is smaller than 5 cm but cancerous cells are in nearby lymph nodes. |
Stage 2B: One of the following is true:
| |
Stage 3 | Stage 3A: In this stage the cancer is either within the lymph nodes located in the center of the chest or it has spread to the surrounding tissue. The surrounding tissue can include the middle chest region, the chest wall, the pleura which covers the lung, or other lymph nodes that are located close to the lung. |
Stage 3B: In this stage, the cancer spread to one of the following places:
| |
Stage 4 | Stage 4 lung cancer means that the cancer is either in both lungs or has entered another area of the body (like the brain, liver, or bones) or that it has led to the buildup of cancer cells that contain Fluid in The Lungs or heart. |
Small-Cell Lung Cancer
This type of lung cancer is less common and involves smaller cancerous cells when they are observed under a microscope. There are only two stages of small-cell lung cancer:
- Limited Disease means that cancer is only located within the lung.
- Extensive Disease means that the cancer has spread further than the lung.
Treatments for Lung Cancer
Lung cancer is treated via four basic methods: targeted therapy, chemotherapy, radiation therapy and surgery.
1. Surgery
The surgery aims to remove the complete lung tumor as well as the lymph nodes which are nearby in the chest and the removal must include a surrounding margin of healthy lung tissue. If there is a “negative margin” then no cancer was in the healthy tissue around the tumor. The types of surgery used for lung cancer include radiofrequency ablation, pneumonectomy, segmentectomy, a wedge, or lobectomy.
2. Radiation Therapy
Radiation therapy uses high energy particles such as x-rays to destroy the cancer cells. It can be external-beam radiation therapy which involves using a machine outside of the body. There is usually a specific schedule of treatments. Internal radiation therapy (brachytherapy) is less common for lung cancer and involves using implants. This treatment must focus on a specific part of the body.
3. Chemotherapy
Chemotherapy involves the use of drugs which stop the ability of cancer cells to grow and divide, thereby destroying them. It can help with cancer in any stage. Most of the time chemotherapy to treat lung cancer is via IV but it can also be in the form of an oral pill. The treatment can involve one or several drugs and this depends on the type of lung cancer.
4. Targeted Therapy
Targeted therapy treats the specific proteins, tissue environment or genes of the cancer. It blocks cancer from growing and spreading but also limits damage done to healthy cells. The doctor must first run tests to determine which protein, gene, or other factor to target.
How to Avoid the Worsening of Symptoms
Once diagnosed with lung cancer, you can also take several steps to prevent the symptoms from worsening and help deter the cancer from spreading.
- Stay away from cigarettes. Don’t start smoking if you have lung cancer and talk to your kids about the risks of smoking. You should also do your best to avoid secondhand smoke by staying away from places with smokers and encouraging those you know to quit.
- Maintain a healthy diet. Make sure your diet includes fruits and vegetables that contain vitamins and nutrients. Try not to take many vitamins as pills as they can actually increase your risk.
- Know the cancer. Take the time to learn about your cancer as well as the treatment options. This will give you the ability to make informed decisions.
- Seek support from family and friends. Create a support network that can provide emotional, physical and practical support, such as taking you to treatments or helping keep your home clean. You can even look for additional emotional help from various groups.
- Relax and focus. When you feel short of breath, try to relax as Anxiety and fear will make it worse. Try listening to music, praying, meditating or imagining your favorite place to relax.
