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

Skin cancer occurs when the DNA of the cells undergo mutations, thus causing unsystematic cell growth which evolve into a cancerous mass. This abnormality stems from the over-exposure of your skin to the Ultraviolet Radiations of the sun. 

However, there are other factors too that escalate the risks of skin cancer.

Fairer skin tone: Inadequate pigmentation or melanin content in the skin offers less protection against the harmful UV radiations. Having red or blond hair or light-colored eyes makes you more vulnerable to this condition.
Sunburns: A history of sunburns can often be the root cause behind skin cancer.
Excessive exposure to the sun: If you spend a considerable amount of time under the sun and especially if your skin is not protected by clothing or sunscreen, you tend to get a tan. A tan is the skin s response to extreme UV radiations.
Moles: Abnormally large moles, known as dysplastic nevi, are more likely to turn malignant. Watch out for any change in the texture of the moles, which is one of the most important symptoms of skin cancer.
Family history: According to studies, genes are considered to be one of the causes behind skin cancer. Hence, a family history of this condition could spell trouble for one.
Personal history: Having suffered from skin cancer previously in life could endanger one even more.
Pre-cancerous skin injury: Skin lesions, also known as actinic keratosis, make you prone to developing pre-cancerous growths on the skin. These could appear as scaly rough patches, ranging from brown to pink in color. They usually crop up on the hands, head and faces of people who are comparatively of a fairer skin tone.
A weak immune system: People having a poor immunity system, including the ones affected by HIV/AIDS or are on immunosuppressant drugs which follow any organ transplantation have greater risks of developing cancer.
Exposure to radiation: Radiation therapy is an often used treatment method for treating various skin conditions such as acne and eczema. Having been exposed to radiations, one could be indisposed to this condition even more.
Exposure to certain chemicals: Exposure to certain substances such as arsenic might increase your vulnerability manifold.

Skin Cancer - 10 Things That Can Increase Your Risk!

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.

Reduce the Risk of Cancer - Get Tips!

A prostate operation involves the removal of a part of the prostate gland or sometimes the removal of the entire prostate gland. Such a surgery is a serious one and several recovery tips must be followed by a patient to ensure quick and successful healing. 

Here are some important tips for recuperating from a prostate operation:

After the surgery, you need to spend up to three days in the hospital for initial recovery. You might be given fluids, which go directly into your veins until you fully recover from anesthesia.
After the operation, normal urination will be disrupted in the beginning, as the urethra stays swollen. Urinating gets a little difficult and uncomfortable for a few days after the removal of the catheter.
You may feel fatigued and may feel under the weather for some weeks after a prostate operation. So you must take things easy for at least two months.
Avoid lifting or moving heavy objects for some weeks following the surgery. Do not perform any exercise, which causes strain. You should ask your friends and family members to carry out chores for you.
After becoming slightly stable you should start gentle exercises. Walking is an effective remedy, which helps in blood circulation and lowers the risk of getting blood clots in the legs.
You should drink lots of water during the recovery stage. This will reduce the risk of getting a urinary tract infection and also help in clearing any trace of blood from your urine.
For improving bladder control, you should perform several pelvic floor exercises.
In case of any kind of pain, you can take over the counter painkillers to ease the pain.
It will take you a time span of three to six weeks for total recovery after a prostate operation. You should consult your surgeon about the best time to return to normal daily activities.
You can get back to work soon, but it depends on your nature of work. Office jobs are not much of a problem, but in case of physical labour, more time is needed before you can resume your duties.
Activities such as driving can be started quite soon after initial recovery. However, it varies from person to person. Some people may get back to driving within two weeks while some may need a month.
You have to wait for 6 to 8 weeks after a prostate operation before getting back to sexual activities.
In case you experience high fever, pain during urination or the inability to urinate, you must consult your doctor immediately.
It takes a person several weeks to recover from a prostate operation completely. Initially, total rest is required. But eventually, he can return to normal activities and lead a healthy life.

14 Tips to Help You Recuperate from Prostate Operation

Irrfan Khan's saddening revelation about his health and diagnosis of Neuroendocrine tumour (NET) has undoubtedly created a rage amongst his fans, which is now being followed by good wishes for speedy recovery from his supporters all across social media.  

The actor shared in an emotional Twitter post that he s been diagnosed with NET, a rare tumour that develops from cells of the neuroendocrine system and grows predominantly in the digestive or respiratory tract - lungs, appendix, small intestine, rectum, and pancreas - it can occur in any part of the body.

Here is more on Irrfan s disease:

What is NET?

A neuroendocrine tumor is characterized by a rapid and abnormal growth that happens in the nerve cells which produce hormones. Hormones control how different organs in the body work.

It is a condition wherein, endocrine cells, the hormone-producing cells of the body, develop a tumor in any part of the body - while it can can grow in lungs or the thymus, or more rarely, in the ovaries, kidneys, or testicles - the most common is lung, intestines, and pancreas.

What causes NET?

A neuroendocrine tumour is quite a rare disease, occurs in less than one per million cases. The exact cause is not known.

The Symptoms-

It can cause a myriad of symptoms, depending on where in the body the NET is.

If it is in your digestive system, it can cause pain or discomfort in the abdomen area that comes and goes. You may feel sick, nauseated, vomited, or there may be a change in how often you pass stools.
If the NET is in the lung, it can cause shortness of breath, chest infections, or you can even have a cough up blood.
Weight loss and loss of appetite may also be some common signs of a neuroendocrine tumour.
Some NETs may overproduce a hormone-like substance called serotonin. This causes a group of symptoms called carcinoid syndrome. Symptoms include wheezing (like asthma), flushing of the skin and diarrhoea.
Who can be affected with NET?

These tumours, depending on the type, are more common in certain age or sex. And few have very strong family history too.
People who have a rare condition called multiple endocrine neoplasia 1 have an increased risk of developing a NET.
Did You Know?

Apple founder  Steve Jobs  died from the same disease in 2011. The tumour affected his pancreas.

Know The Different Types of NET:

Based on the organ that is affected, NET can vary a lot. When the chromaffin cells that produce adrenaline are affected, it is called Pheochromocytoma, and it is related to the stress levels of the body.

When a cell is formed abnormally under the skin and the hair follicles, it is called Merkel cell cancer. This is also called neuroendocrine carcinoma of the skin and the condition can occur anywhere in the body. The commonly occurring places include lungs, gastrointestinal tract, and brain.

The status of the tumour, cancerous (malignant) or noncancerous (benign), decides the survival rate. Often slow-growing and noncancerous, they can invade surrounding parts of the body and at times, turn cancerous and spread across the body. However, you can still choose to live a good quality life with strict modifications in diet and lifestyle. The changes are made after taking into consideration the symptoms of the tumor. The organ where the tumor is formed also matters.

How Is It Treated?

Treatment depends on the location of the tumour, its type, how severe it is and whether it has spread to other parts of the body. Usually, the first treatment choice is surgery to remove the tumour. And, if the NET cannot be removed, your will prescribed with a treatment that will not only relieve the symptoms but will also improve the quality of your life.

How can a NET be prevented?

The first thing you need to do for the prevention of NET is to curb stress. Stress affects the entire body severely.

Lifestyle modifications:

A healthy lifestyle is what you need to stick to if you want to manage its symptoms during the treatment cycle. Your doctor will prescribe you to do exercises at least 4 days a week for a minimum of 30 minutes. You can also try a walk instead of strenuous exercises.

People with carcinoid syndrome may be advised to avoid food or activities that may trigger flushing, such as eating spicy food or drinking alcohol.

Indulge yourself in therapies that help in gaining more positive energy. If you are already affected by NET, eliminate all the sources of stress and get a good night's sleep every day. Join the support groups that make you grow strong and happy. After all, the mind is devised to do miracles when it is full of life and positive thoughts.

Is Irrfan Khan's tumour curable?

Dr Saumitra Rawat, HOD, Surgical Gastroenterology & Liver Transplant, Sri Ganga Ram Hospital, said, "NeuroEndocrine Tumour is an abnormal growth of Neuroendo cells which are present in bodies. When there is an abnormal growth, then it forms a tumor - Normally seen in intestine, pancreas, lung, thyroid and other parts of the body".

On commenting on Khan's case, he said, "It depends on the location of tumour, its size, and what is its mitotic index".

"Depending on where the tumour is localized, you can take it out surgically and the chances of cure are very high", Dr Rawat explained.

Actor Irrfan, who has been diagnosed with the disease is one of the most versatile actors in India, has also made a name for himself in the west, where he has been an important part of critically-acclaimed films such as  The Namesake ,  Jurassic World , and  Life of Pi . At home, the actor has delivered remarkable performances in films such as  Haasil ,  Paan Singh Tomar ,  Maqbool ,  Lunch Box ,  Piku , and the most recent  Hindi Medium .

Irrfan Khan is not just a disarmingly natural actor, but also an endearing human being -- honest and humble to the core. It s time to stand together and pray for him a speedy recovery!

Irrfan Khan - Battle Against Neuroendocrine Tumour!

One of the most common problems faced by ageing men is benign prostatic hypertrophy. Prostate is the gland at the base of the urethra near the bladder and when it enlarges it can lead to symptoms, mostly related to urination.

1. Frequent urge to pass urine
2. Prolonged urination
3. Frequent nocturnal visits to the toilet
4. Intermittent urination
5. Difficulty to start urinating
6. Inability to completely empty the bladder
7. Urinary tract infections

There are medications available to manage this, but offer only temporary relief. Many men therefore prefer to have the surgery undergone to manage these bothersome symptoms. However, like any surgery, the risks and benefits need to be considered along with other conditions like age, overall health status, other comorbid conditions, etc.

Surgical removal of the enlarged prostate gland is a more definitive approach to manage these symptoms. In addition to providing a quick cure, it also is used in the following cases:

1. Patients who do not respond to medications
2. Presence of blood in the urine
3. Associated bladder stones
4. Frequent infections of the urinary tract
5. Associated damage to the kidneys

Procedure of Surgery
During the procedure, a tube is passed through the tip of the penis into the urethra towards the bladder neck. Once it is in the desired position, laser is passed through it to deliver energy that acts on the prostate to either completely or partially destroy it. There are two methods by which laser acts on the enlarged prostate and making way for free flow of the urine.

1. Ablation: Excess prostate tissue is melted away by the laser by using photosensitive vaporization of the prostate. This is also known as Greenlight laser therapy or KTP laser vaporization. Alternately, Holmium can be used as the source of laser energy to ablate the prostate tissue.

2. Enucleation: Excess prostate tissue is cut and teased out through the urethra. Holmium laser is used to resect the prostate into smaller pieces, which are then removed out through a resectoscope. Another technique uses a tissue morcellator which grinds the enlarged prostate into smaller pieces to enable easy retrieval.

More men now opt for laser prostate removal as it has the following advantages:

1. Reduced risk of bleeding: This becomes essentially important in patients who are on blood thinners.
2. No hospitalization: This can be done either as an outpatient or with minimal one day stay at the hospital
3. Immediate symptom relief: As compared to medications, the relief is felt almost immediately after the surgery
4. No catheter: With laser surgery, a catheter may be required for less than 24 hours unlike in open surgical cases.

As noted above, as with any surgery, once enlarged prostate symptoms set in, have a detailed discussion with your doctor to identify if you are a suitable candidate for laser surgery.
