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

Science has advanced a lot through the ages. Doctors have also succeeded in curing many diseases in this time. But even with one of the most advanced technologies, they still haven t found a fool proof way to cure cancer. Even out of the many types of cancer, blood cancer is the worst among them. You surely wouldn t want to get into such a situation. Would you? The best way out of blood cancer is never to get one. To prevent it you can take care of a few things:

Maintaining proper body weight: Although you can t do much to prevent cancer, you must ensure that you maintain a healthy body weight. This implied that your BMI should be normal (healthy weight) so that you have a good chance of fighting it. It has been said by many leading institutions worldwide as the best way to prevent cancer. One can maintain proper body weight by making sure they exercise every day for at least 30 minutes and also maintain a well-balanced diet. This would help you maintain a healthy body weight.
Reduction in the consumption of calorie dense food: Not only because calorie dense foods like cold drinks increase your weight, the sugar mixes with your blood and thus is difficult to transport through the body. Thus they add a lot of impurities to the body and must be avoided for the best interests in your effort to fight cancer. The worst fact about calorie dense foods is that you can easily consume 1000   2000 calories long before you can satisfy your hunger. Thus, it also defeats your first preventive measure to avoid cancer.
Staying away from harmful chemicals like pesticides: You might not know it and be happily spraying pest control sprays everywhere without a proper mask thinking you will make the pests go away. What you don t know is that those pesticides are harmful for your blood and one should avoid them. To increase the probability of winning against blood cancer, it s vital to keep this in mind.
Consulting a doctor from time to time: One should always go and visit a medical practitioner from time to time so that they can maintain proper health. Furthermore, if you see symptoms like fever, frequent infections, night sweating, swollen liver with abdomen pain, enlarged lymph nodes (they are usually painless), then be sure to go to a medical practitioner. Always remember that prevention is better than cure. Thus one should try to prevent blood cancer not cure it.

Blood Cancer - How To Prevent It? 

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.

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

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.

8 Easy Ways By Which You Can Prevent Prostate Cancer!

Causes and symptoms of enlarged prostate

The problem of an enlarged prostate or benign prostate hyperplasia is a very common occurrence as you grow older. It's known to strike men above the age of 50, with more than 50% of men after the age of 60, having this complaint.

Causes of enlarged prostate

A non-cancerous condition, enlarged prostate makes the passing of urine from the bladder through the urethra difficult. The multiplication of the prostate cells causes an enlargement of the gland, leading to a buildup of pressure on the urethra, affecting the discharge of urine from the body. The narrowing of the urethra, due to this benign condition, forces the bladder to contract more vigorously so as to push urine out of the body.

As time passes, the muscles of the bladder get significantly affected, causing them to become extremely sensitive, thicker and stronger. As a consequence, the bladder begins to contract, even if the amount of urine in the organ is negligible, causing episodes of frequent urination. Gradually, the bladder fails to completely empty itself of urine due to the constriction of the urethra. This can give rise to a number of health problems including the formation of bladder stones, urinary tract infections, blood in the urine and so on.

How can you identify the signs of the condition?

Signs of enlarged prostate are very easy to identify and include:

- A slow or weak urine flow
- Difficulty in initiating urination
- Instances of frequent urination
- A feeling of not completely emptying one's bladder
- Frequent urination during the night
- Exerting a lot to urinate
- Instances of dribbling
- Urgency to pass urine
- A feeling of urinating again minutes after doing so
- Urination that starts and stops
