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

The most dreadful part of getting to work and getting back home in the evening is the being stuck in a traffic jam. Whether you re driving yourself or being driven home, a traffic jam can sap your spirits and make you feel tired even though you re not really exerting yourself. According to a recent study, these traffic jams not only increase your stress levels, but also make your body susceptible to cancer.

Yes! They can be a major reason behind your ill health-

Bumper to bumper traffic that moves at snail pace can be very stressful, especially if you have to get somewhere at a particular time. The irritation of not being able to move at your desired pace adds on to the million other things going on in your mind. The body reacts to stress by increasing blood sugar and blood pressure levels. Long term stress can lead to digestive problems, fertility issues and a weakened immune system that makes the body vulnerable to other diseases and infections. Stress can also lead to the development of behavior like smoking, drinking and over eating which can increase a person s risk of cancer.
Pollution levels are highest at traffic signals and at traffic jams. This is because at a busy intersection, cars go through various stages such as accelerating, braking and idling in a restricted space. Each of these actions is accompanied with emission of toxic gases and fine particles of matter which concentrate in an area and take longer to disperse. Contrary to popular belief, people in cars can be more affected by these pollutants than pedestrians. This is especially true in cases where people have their windows up and fans on as the fans suck in polluted air leading to a buildup of toxic gases inside the car. When these gases and particulate matter are inhaled, they get stuck in the nose and throat and are absorbed into the blood stream. Long term exposure to this can have serious negative effects on the body including a higher risk to cancer. To avoid this, ensure that the setting of the ac of your car or fan is set to only circulate air inside the car without drawing in polluted air from outside.
Also, try and find ways to avoid traffic jams. If your office allows, maybe you could try changing your timing a little. Experiment with routes. Often the inner roads have more twists and turns but much less traffic.


Traffic Jams - Can they Make Your Body Susceptible to Cancer

The prostate gland in males surrounds the urethra, through which urine and sperm are passed out of the body. Its function is to secrete a fluid, which provides nourishment to the sperm. It is about the shape of a walnut and is present between the pubic bone and the rectum.

As a man crosses 40, the prostate gland begins to increase in size due to an increase in the number of cells. This is known as hyperplasia.  The condition is usually benign and therefore the name benign prostate hyperplasia (BPH). As it continues to grow, there is an increased pressure on the urethra. Therefore, there can be problems with urination. The bladder, being a muscular organ, compensates to some extent and so the problems with urination are mostly managed. If left untreated, this can continue to be a major problem and the bladder may not be able to compensate. In men who are 60-plus, BPH is very common.

Signs and symptoms 

One of the initial symptoms of BPH is when the urine stream begins to grow weak.
There could also be a reduced speed of passing urine.
Men with BPH never have a feeling of complete emptying of the bladder.
On the other hand, there is also a constant difficulty in initiating a urine stream. There could be intermittent breaks in the urine stream.
The person may feel the need to strain to initiate the stream and to ensure complete emptying.
There could be dribbling of urine after passing urine.
The duration between two bathroom visits can constantly reduce, with the constant urge to urinate.
There is a constant urge to visit the bathroom, which is more common in the night. One of the most annoying features of BPH is the walking up at night to urinate, but with an inability to initiate a stream and an inability to completely empty the bladder, it leaves the person very irritated and frustrated.
There could be blood in the urine. In fact, blood in the urine accompanied by fever, chills, nausea and vomiting are indications of an emergency.
There could be blockage of urine completely, if the enlargement is quite severe.
Diagnosis
If you are having any of these symptoms, then the doctor will first test for an enlarged prostate through a digital rectal exam. Then a test is done to check a chemical called prostate specific antigen.  Increased levels of this chemical is almost always indicative of BPH. In addition, X-rays and scanning may be used to confirm diagnosis. 

Treatment
Though medications are available, confirmatory treatment is through surgical removal. The procedure needs a inimum of 2 to 3 days.

Enlarged Prostate - 10 Warning Signs To Watch Out For

Medical science constantly challenges the boundaries by finding not only the cures to the most dangerous diseases, but finds a way to prevent them even before they occur. With years of research, practice and data available for analysis, scientists are using advanced technology in combination with years of research to create a predicting mechanism for often fatal diseases like cancer.

Breast cancer screening has always been done with mammography. The fact is that this method is only 75% accurate, laden with false positives and misses a whole set of women totally- and that too when cancer has already developed. Part of the problem comes from the dense breast tissue which one in three women have. This tissue masks the lumps, which makes it difficult for mammograms to accurately screen cancer.

Some breakthrough scientific methods are changing this by drawing on years of research to predict this deadly disease, years before it can manifest itself.

A genetic test to predict cancer 10-11 years ahead of time
This test was performed to see how environmental factors could influence cancer, along with habits like smoking, abusing alcohol or hormones, genetic changes that occur and are put a large percentage of the women at a high risk of developing this disease.

A simple blood test is used for the genetic analysis of hereditary cancer. Researchers found a biological marker, methylation of the ATM gene, which has a very high ability to predict the risk of developing cancer, several years before diagnosis. 'Methylation' concluded that when one biological indicator is exposed to carcinogenic substances, or other abusive substances like tobacco and alcohol, it may trigger the development of cancer. On the flip side, this test will take time to reach the commercial market and even then cannot give an exact timeline as to when someone may develop the disease.

A simple blood test to predict breast cancer 5 years before it develops
This is the kind of medical miracle the world is looking for. Last year in April, researches in Denmark identified a simple blood test that can predict breast cancer five years before it actually develops with an accuracy of a whopping 80%.

It works by "measuring all of the compounds in the blood to build a 'metabolic profile' of an individual, in order to detect changes in the way chemicals are processed, during a pre-cancerous stage," says Laura Donnelly, health editor at The Telegraph, which covered this development. Danish researchers observed 57,000 participants over 20 years, gathering blood samples along the way, specifically comparing a set of 800 women who remained healthy or developed breast cancer within 7 years of their first blood sample. The researchers found they were able to predict, with 80 percent accuracy, which patients would be affected by the disease, just by looking at the metabolic profiles they built from the participants' blood samples. The results have been published in Metabolomics.

Can Breast Cancer Be Predicted Before It Develops?

Cancer is the most dangerous disease noticeable throughout the world. The most common type of cancer that affects men is prostate cancer. Prostate is a small exocrine gland situated directly below the bladder and in front of the rectum. This is gland is approximately in size of a walnut and plays an important role in production of a milky fluid during orgasm of sex in which the semen travels. During the climax stage of the prostate gland is forced to push the fluid and remove the semen out of the reproductive structures.

Prostate gland is a slow progressive disease which makes many males left unidentified even the presence of prostate cancer even until they die. 6 out of 100 male over the age of 60 are getting prostate cancer. Though prostate cancer can be cured at a better rate when compared to other type of cancer it is always best to stay protected. Prevention is always better than cure. Here are few tips to keep your prostate healthy.

Signs and symptoms of prostate cancer-

During the early stages of prostate cancer there are usually no symptoms. Most men at this stage find out they have prostate cancer after a routine check up or blood test. When symptoms do exist, they are usually one or more of the following:

The patient urinates more often

The patient gets up at night more often to urinate

He may find it hard to start urinating

He may find it hard to keep urinating once he has started

There may be blood in the urine

Urination might be painful

Ejaculation may be painful (less common)

Achieving or maintaining an erection may be difficult (less common).

If the prostate cancer is advanced the following symptoms are also possible:

Bone pain, often in the spine (vertebrae), pelvis, or ribs

The proximal part of the femur can be painful

Leg weakness

Urinary incontinence

Fecal incontinence

Ways to have a healthy prostate  

Diet and weight   the most important factor is the diet to maintain a healthy weight. Avoid fatty food items and take fats from vegetables than from animals. Avoid dairy products and increase the intake of fresh fruits and vegetables.

Exercise   have a regular practise of doing exercise at least for 30mins a day. This really helps you to keep your body fit.

Be precautious   if you have a family history of prostate cancer or if you feel you are at high risk of getting prostate cancer talk with your doctor about it and take preventive drugs as per the doctor s advice.

Red foods   research shows that men who consume red foods like watermelon, tomato and other red fruits are at lower risk of getting prostate cancer as they contain a powerful antioxidant called lycopene

Caffeine   three to four cups of coffee per day reduces your risk of getting prostate cancer.

Stop smoking   if you are at high risk of getting prostate cancer it is best advised to quit smoking and alcohol.

Prostate Cancer - What To Expect

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.

Abstain from tobacco: Consuming raw tobacco or smoking tobacco can be equally detrimental to your health. Tobacco increases your chances of contracting the disease. As is known, passive smoking can also affect your health adversely. Tobacco can be the potential cause behind cancer of the mouth, throat, larynx, lungs, oral cavity and even the pancreas. It might harm your kidneys and cervix. It is upon you to quit tobacco at the earliest possible. One should also try and persuade friends and relatives to give up smoking.
Drink alcohol in moderation: Complete abstinence from alcohol might not be possible if you have already been ushered into your work- life. The society might require you to be an occasional drinker. It is important to drink in moderation. Crossing the limit can propel consequences as serious as cancer of the stomach, pancreas, liver and the heart.
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 sexually transmitted 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.
