Lung cancer is caused by disorderly growth of uncommon cells which line the air passage, usually starting off in a single or both lungs. The irregular cells do not mature into healthy lung tissue but instead divide speedily and result in tumor formation.

Causes behind lung cancer:

Smoking: This is considered as the most significant source of lung cancer. As reported by multiple researches and studies, cigarettes contain over 4,000 chemicals, most of which are cancer causing agents. Active smoking is one of the major causes of lung cancer but what may come to you as a surprise is that extended periods of passive smoking is also a major factor.
Pollution and Exposure: There is high risk of lung cancer development when there is occupational exposure to pollution by chemicals released from industrial factories. Chemical exposure of this kind refers to prolonged exposure over quite few months or years. Some examples of these chemicals are asbestos, diesel exhaust among many others.
Radioactive Gas: Radioactive gases naturally occur in small masses present in all soils and rocks. However, if you breathe in radioactive gases your lungs will damage and may cause the development of abnormal tissue which can cause lung cancer.
Family history: A family history of cancer, especially lung cancer will also put you at high risk of developing lung cancer.
Treatment methods of lung cancer:

Chemotherapy: Chemotherapy is a method in which drugs are injected through veins in your arm (intravenously) or orally or in a combination of both. These drugs kill cancer cells and help to stop it from spreading any further as well.
Clinical Trials: These trials are experimental lung cancer treatment studies. You may have to try out this clinical therapy if other treatment methods aren t working and only if you are accepted into it.
Surgery: A surgeon will help remove affected areas of the lung including cancerous tumors via surgery. The surgeon may need to remove parts of the lung along with the cancerous growth. In certain cases, one side of the lung may also be completely removed to stop the spread of the malignant tissue.
Radiation Therapy: This is a therapy where high energy electromagnetic waves are passed through your body to destroy cancer cells with the help of high-powered energy beams.
Can you prevent lung cancer?

Nutrition -- A  healthy diet with lots of fruits and vegetables may also help reduce your risk of lung cancer. Some evidence suggests that a diet high in fruits and vegetables may help protect against lung cancer in both smokers and non-smokers. But any positive effect of fruits and vegetables on lung cancer risk would be much less than the increased risk from smoking.
Exercise -- Even moderate amounts of exercise can aid in lung cancer prevention. Studies suggest that even something as simple as gardening twice a week is associated with a lower risk of developing lung cancer.
Smoking Habits -- If you stop smoking before a cancer develops, your damaged lung tissue gradually starts to repair itself. No matter what your age or how long you ve smoked, quitting may lower your risk of lung cancer and help you live longer. 
Avoidance of Air Pollution -- Long-term exposure to ambient air pollution and, in particular, particulate matter with absorbed polycyclic aromatic hydrocarbons and other genotoxic chemicals has been suspected to increase the risk for lung cancer. So, avoid air pollution as much as possible.

Lung Cancer - Ways You Can Prevent It!

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.

Surgical Procedure for Treating Breast Cancer

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

Lasers have come as a boon to treat many medical conditions very safely and effectively. They are absolutely indispensable for permanent hair removal, tattoo removal, freckle removal, skin rejuvenation, treatment of birthmarks and many other internal medical conditions. There is a common misconception that lasers are harmful for your skin and can cause skin cancers. This is far from the truth, since lasers are actually used to treat skin cancers and also help in keeping the skin youthful and rejuvenated. 

Lasers use non-ionising light (like red or green light) and not ionising radiation like x-rays or gamma rays. These spectrums of light do not induce cancer formation. 
Fair skinned races are at much greater risk than skin of color. Melanin in darker skin does not allow harmful UV light in sunlight to penetrate through and the risk of skin cancers in darker skin is therefore small with normal sun exposure. Also, common lasers do not use UV light. 
Laser treatments are administered not in prolonged durations but in pulses much less than a second and parameters in the range of milliseconds and microseconds are most commonly used. Prolonged sun exposure is the most common precipitating factor for skin cancers. 
Laser light does not reach any internal organ. In fact, it requires some expertise even to make laser light reach its target just 1-2 millimeters below the skin. This is because melanin pigment in skin blocks laser light from getting through. An expert dermatologist with sound knowledge of skin optics and laser physics is able to achieve this safely and effectively. 
Laser treatments work on the principle of ''selective photothermolysis'. This means that laser light very specifically destroys only the intended target. Thus, a hair removal laser will destroy only the hair roots while leaving surrounding skin structures unharmed. Similarly, blood vessels in birth marks, collagen in wrinkles or scars, abnormal growths and cancers and individual inks in tattoos can be targeted very specifically with lasers without affecting any other structure.

Lasers - Do Not Cause Cancers!

International Childhood Cancer Day is celebrated annually on 15 February to raise awareness and to express support for children and adolescents with cancer, survivors and their families.
We live in an age where every single individual, more or less, is exposed to the risk of cancer. It is probably an unfavorable lifestyle we lead that deprives us of good health. This might alarm many but considerable changes in lifestyle can help you realize cancer as a preventable disease. Cancer does not only make you undergo severe suffering but it also affects your friends and family. The pallor of misery spreads wider than you think.

A balanced and nutritious diet: Deciding on a plant- based diet or a Mediterranean diet can aid your fight against the risk of cancer. A Mediterranean diet will involve green leafy vegetables, lots of fresh fruits, whole grains, mixed nuts, legumes and also the use of extra- virgin olive oil. Fish can be a safe bet but red meat should be avoided. One must also try to avoid processed meat as they tend to make you prone to the risk of cancer.
Immunization: Hepatitis B and HPV or Human papilloma virus vaccines are extremely necessary to protect you against the every types of cancer.
Sun protection: Caring for your skin doesn't arise from vanity. Skin cancer is one of the most prevalent kinds of cancer; the chances of this disease can be restricted by remaining in shade especially during midday, by wearing covered clothes and by using a good sunscreen lotion repeatedly while outside.
Exercise diligently: Did you think it was okay to have weaker muscles and bulging layers of fat? If yes, you probably have grown numb to the inadequacies you face in result. Unchecked fat can lead to obesity which further complicates health conditions. Metabolic activity differs from person to person. Regular exercising can help regulate metabolism according to the needs of your body. Physical exercise protects you against the risk of breast and colon cancer. Moderate or vigorous physical activity for 150 to 75 minutes a week respectively can reduce the risk of cancer.

International Childhood Cancer Day - Few Tips to Reduce the Risk of Cancer

A gland that produces a liquid which mixes with sperm and is ejaculated as semen during sexual activity, is the prostate gland and is located under the bladder of a man. Cancer in the prostate is one of the most common cancers that occur among men.

The risk of developing prostate cancer increases progressively with age. Although there is no absolute prevention of prostate cancer, evidence and doctors suggest that a healthy diet can play a key role. Here are a few tips that can go a long way in prevention of prostate cancer:

Red Foods: Tomatoes, carrot, watermelon, and other red foods get their bright color from a powerful antioxidant called lycopene. Studies have proved that by having fruits that contain lycopene, you can reduce your risk of prostate cancer. Some findings suggest that cooking tomatoes make it easier for your body to absorb this antioxidant.
Fruits and Vegetables: Green vegetables contain compounds called carcinogens, which help your body in breaking down cancer-causing substances. Spreading of cancer can be slowed down through a nutrient-rich diet. Avoiding processed junk food and eating fruits and vegetables containing nutrients and vitamins may lower the risk of getting prostate cancer.
Feast on Fish: Fatty acid, also known as omega-3, is found in certain fish including sardines, tuna, mackerel, trout, and salmon. This may help in reducing the risk of developing prostate cancer.
Soy and Tea: Some studies suggest that men who drink green tea or take green tea extract supplements have a lower risk of developing prostate cancer. Many soy products and other foods contain a nutrient called isoflavones, which has been linked to a reduced risk of prostate cancer.
Coffee: Studies show that drinking three cups of coffee a day can reduce the chances of prostate cancer by 11 percent. There is a dose-response relationship between coffee and prostate cancer. The effects of prostate cancer go up or down with the amount of coffee you take. Someone who grabs an occasional cup only, may not have these effects. However, high doses of caffeine can result in major health issues.
Fat: Studies indicate that animal fats and an increased risk of prostate cancer are linked. It is advised to replace animal-based fats with any kind of plant-based fat. In addition to this, overcooking the meat produces carcinogens, therefore it is suggested to be strictly avoided.
Quit Smoking: Smokers are more likely to have an aggressive form of prostate cancer. The chances of a recurrence of the disease are more for people who smoke. It is never too late to quit smoking.
Exercise: Regular exercise and maintaining a healthy body can help you to increase your muscle mass and metabolism. Too much fat in the middle of your body is linked to an increased risk of prostate cancer. You can try walking, running, bicycling or swimming to reduce the weight to lead a healthy life.
It is important to look after yourself and start taking essential steps to prevent prostate cancer rather than trying to manage it once you get it.
