Lung cancer is the uncontrolled growth of abnormal cells in one or both lungs. These abnormal cells do not carry out the functions of normal lung cells and do not develop into healthy lung tissue. As they grow, the abnormal cells can form tumors and interfere with the functioning of the lung, which provides oxygen to the body via the blood.

Lung cancer is the most common cause of death due to cancer in both men and women throughout the world. According to the U.S. National Cancer Institute, approximately one out of every 14 men and women in the U.S. is diagnosed with cancer of the lung at some point in their lifetime. Lung cancer is predominantly a disease of the elderly; almost 70% of people diagnosed with lung cancer are over 65 years of age, while less than 3% of lung cancers occur in people under 45 years of age.

What Causes Lung Cancer?

The development of lung cancer is strongly associated with cigarette smoking, approximately 90% of lung cancers are attributable to use of tobacco. Pipe and cigar smoking can also cause lung cancer, but the risk is not as high as with cigarette smoking. Tobacco smoke contains more than 4,000 chemical compounds, many of which are cancer causing (carcinogens). Passive smoking, i.e. the inhalation of tobacco smoke by non-smokers who live or work with smokers, is also an established risk factor for the development of lung cancer.

Genetic susceptibility (i.e. family history) may play a role in the development of lung cancer. Other causes of lung cancer include air pollution (from vehicles, industry, and power generation) and inhalation of asbestos fibres (usually in the workplace).

Lung Cancer Symptoms

Early symptoms and signs of lung cancer

There may be no symptoms at the onset of the disease. When present, common symptoms of lung cancer may include:

Coughing: This includes a persistent cough that doesn't go away or changes to a chronic smoker's cough, such as more coughing or pain.
Coughing up blood: Coughing up blood or rust-colored sputum (spit or phlegm) should always be discussed with your doctor.
Breathing Difficulties: Shortness of breath, wheezing or noisy breathing (called stridor) may all be signs of lung cancer.
Loss of Appetite: Many cancers cause changes in appetite, which may lead to unintended weight loss.
Fatigue: It is common to feel weak or excessively tired.
Recurring infections: Recurring infections, like bronchitis or pneumonia, may be one of the signs of lung cancer.
Signs of advanced stages of lung cancer

Advanced stages of lung cancer are often characterized by the spread of cancer to distant sites in the body. This may affect the bones, liver or brain. As other parts of the body are affected, new lung cancer symptoms may develop, including:

Bone pain
Swelling of the face, arms or neck
Headaches, dizziness or limbs that become weak or numb
Jaundice
Lumps in the neck or collar-bone region
Treatment

Treatment for cancer involves a combination of surgery to remove cancer cells, chemotherapy and radiation therapy to kill cancer cells. Lung cancer is incurable unless complete surgical removal of the tumour cells can be achieved. Surgery is the most effective treatment for lung cancer, but only a few percentage of lung cancers are suitable for surgery i.e. Stage I and II NSCLC and cancer that has not spread beyond the lung.

Radiation therapy may be used for both NSCLC and SCLC and is a good option for people who are not suitable for surgery or who refuse surgery. Chemotherapy is used for both NSCLC and SCLC. Chemotherapy drugs may be given alone or in combination with surgery or radiation therapy. Chemotherapy is the treatment of first choice for SCLC since it has usually spread extensively in the body by the time it has been diagnosed.

Also used in the treatment of lung cancer are targeted therapies. These are drugs (gefitinib and erlotinib) or antibodies (cetuximab, bevacizumab) that block the growth and spread of cancer by interfering with specific molecules involved in tumor growth and progression. They are used in some patients with NSCLC that does not respond to standard chemotherapy.

Lung Cancer: Causes, Symptoms and Treatments

With the recent number of breast cancer cases on the rise, it is important that we should get the examination done on a regular basis as a preventive measure. Even if someone is suffering from it, it is important that we should make an effort and learn about.

If you have breast cancer then a surgery will be part of your treatment. Based on the condition, surgery will be carried out due to any of the following reasons:
1. To remove the cancerous tissues from the breast
2. To reconstruct the breast once the cancer is removed
3. To check whether the cancer has spread to the lymph nodes below the arm
4. To treat symptoms of cancer that has progressed to an advanced stage

Breast cancer surgery may be classified into two types
1. Mastectomy: Mastectomy involves removing the entire breast; tissues in the adjoining region may also be removed. A double mastectomy is a procedure where both the breasts are removed.
2. Breast-conserving surgery: In this surgery, only parts of the breast affected by cancer are removed. The area of the breast that is to be removed will depend on the severity of the cancer. Some healthy tissues may also be removed in this surgery.

Usually, if a woman is in the initial stages of cancer then she may opt for the latter as it entails removing parts of the breast. They may also undergo radiation therapy along with these surgeries.
For checking if the cancer has spread to the lymph nodes below the arm, the lymph nodes are removed from the body. Once they are removed, they are studied under a microscope to check if it has spread, if yes then the extent of their damage. This procedure is carried out along with the surgery to remove the cancer.

Once the mastectomy procedure is completed, you can opt for a breast reconstruction surgery to rebuild the area. You may opt for this procedure at the time of breast cancer removal or at a later stage. If you are considering breast reconstruction surgery then you should discuss it with your surgeon.

Surgery is sometimes not used to treat cancer, but in slowing the progression of cancer or even reducing its symptoms.It is important you talk to your surgeon before the procedure to understand the goal of the surgery.

How to become less prone to cancer

There are various known reasons why cancer takes root in a healthy body. The deadly disease takes away millions of lives worldwide and remedies in food to tackle it are constantly a subject of research. However taking this one food item off your daily diet can help becoming less prone to cancer.

Senior cancer experts stress that sugar feeds cancer. According to his belief, backed by years of research and medical expertise, it is possible to starve cancer out of a person’s body. When sugar breaks down in the body in a non-oxidative manner, adenosine triphosphate (ATP) is generated which causes cancer cells and tumor to grow.

Research states that cancer is a dysfunction of the mitochondria caused by fermentation of sugar in the cells instead of orthodox respiration of normal cells. This can be tackled by limiting the supply, just by cutting down the intake of sugar every day. A small amount of sugar in a healthy and requisite proportion is acceptable but excessive sugar must be avoided in order to choke cancer out from the body.

Specifically, the intake of sugar in processed foods must be cut down. Everything that is sweet isn't sugar! Avoiding processed foods will simply eliminate the bad salts and bad sugars from your diet. Eating at fast food joints too must be cut down completely as the food they serve is frozen and needs a lot of preservatives. You can always switch to fruits if you have a sweet tooth. Diet-wise, consume more green leafy vegetables, developing a plant and natural nutrient based diet is an ideal method to tackle cancer.

Are You Aware That You Are Feeding Cancer Daily?

Lung cancer is the cancer killer of both men and women in the world. When you think of risk factors for lung cancer, what comes to mind? Most of us think about the risk associated with smoking cigarettes, but did you know that air pollution can also cause lung cancer? Overwhelming evidence shows that particle pollution in the outdoor air we breathe like that coming from vehicle exhaust, coal-fired power plants and other industrial sources - can cause lung cancer. Particle pollution increases the risk of dying early, heart disease and asthma attacks, and it can also interfere with the growth and function of the lungs. 

What is Particle Pollution?

Particle pollution is a mix of tiny solid and liquid particles in the air and can be made up of a number of components, such as acids, organic chemicals, metals, soil and dust particles. It can be emitted directly from wood stoves, forest fires, vehicles and other sources, and it can also form from other types of pollution that come from sources like power plants. 

Why does particle pollution harm our bodies?

While breathing in larger sizes of particle pollution can be harmful to our health, smaller particles are more dangerous. Bigger particles can irritate your eyes, nose and throat, but our natural defenses help us to cough or sneeze them out of our bodies. Unfortunately, those defenses don't keep out smaller particles, which get trapped deep in the lungs and can even get into the bloodstream, causing damage to our health.



Who is most at risk?

As for who is at risk for health problems from breathing in particle pollution. Those who live where particle pollution levels are high is at risk. Some people face higher risk, including children, the elderly, people with lung and heart disease and diabetes, people with low incomes, and people who work or exercise outdoors.

How do we protect ourselves from particle pollution?

Check the air quality index forecast for the day and limit your activity if pollution levels are high. Avoid exercising along heavily traveled highways regardless of the overall forecast.

As individuals, we can play our part in reducing air pollution levels by trying to avoid creating more of it. Choosing  active travel  options where possible, like walking and cycling, can help reduce pollution levels from transport and is also a great way to be more active, which is linked to a reduced risk of cancer and other diseases. In case you have a concern or query you can always consult an expert & get answers to your questions!

The Connection Between Lung Cancer & Outdoor Air Pollution!

World Cancer Day, organized by the Union for International Cancer Control (UICC) and celebrated each year on 4 February, is an opportunity to rally the international community to end the injustice of preventable suffering from cancer.
Cancer is one of the worst diseases, which kills millions of people across the world.

Green vegetables: Leafy green vegetables have multiple health benefits. They are not only rich in minerals, vitamins, enzymes, and antioxidants, but also have very low content of calories, toxins, and sodium. Being antiviral and antibacterial in nature, green vegetables can successfully inactivate carcinogens, halt metastasis and pause the formation of a tumour. Certain vegetables contain isothiocyanates that can detox the cells. Some of the vegetables that are mighty effective in countering cancer cells include kale, romaine, watercress, nutritious, spinach, collard greens etc.
Berries: Berries are one of the best antioxidants among all food items, owing to their high ORAC score. Their antiviral and anti-fungal nature of berries is extremely healthy for the body. Moreover, abundant supply of vitamin A and C makes berries a perfect agent for increasing body immunity. Free radicals are one of the top reasons for metastasis. The proanthocyanidin content of berries helps the body to get a hang of free radicals, thereby decreasing the chances of cancer cells to grow rapidly. They can be consumed daily with any meals.
Spices and herbs: There are a lot of herbs and spices, which boost the immune system and prevents cancer cells to grow further. Turmeric, for instance, is scientifically proved to be a great agent for reducing tumor size and effectively countering breast cancer and colon cancer. Some of the other herbs and spices include black pepper, ginger, raw garlic, parsley, oregano, and basil. They can be consumed daily in the form of juice or along with regular meals.
Organic meat: Many scientists are of the view that organic meat does wonder in a cancer diet. Liver of beef and chicken has high B12 content and helps to remove harmful toxins from the digestive tract and liver. They can balance hormone, digest fat and counter the side effects of triglycerides, drugs, and obesity. This can be included in the diet every alternate day.
Seeds and nuts: Flax seeds and chia seeds are few nutrient-power packed foods in the world. They should be included in the diet due to high fiber, mineral, and fatty acid content. Some other healthy seeds that can pay rich dividends in fighting cancer include walnut, sprouted bean, sunflower seeds etc. Nuts and seeds with all their nutritional qualities can successfully stop metastasis, reduce tumor size and increase immunity in the body, if consumed daily.
