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!

Cancer today is not as rare as it once was. Today, cancer affects the young and old alike. One of the reasons for this is the pollution in particular air and water pollution that we are exposed to on daily basis.
The air we breathe in today is a mixture of smoke, particulate matter and noxious gases that causes great harm to our bodies. Amongst these, particulate matter that is smaller than 2.5 millionths of a metre is the worst.

These particle matters are emitted into the air from car exhausts, industrial exhausts, coal fires, wood stoves etc. While the body s natural defences help keep larger particle matter out of the system by sneezing or coughing it out, smaller particle matter enters the body easily. These then get trapped in the lungs and enter the bloodstream. Particle matter has in particular been linked to increasing number of lung cancer cases. Apart from lung cancer, coal tar particle matter has been linked to bladder cancer, soot to oesophageal cancer and benzene and other pesticides to leukaemia.

Radon is another source of air pollution that is emitted from the ground. In some cases, radon can also be emitted through the water. As this gas decays, it releases tiny particles that when inhaled bombard the lung cells with radiation that can cause radiation. Smoking can worsen this effect and increase a person s risk of suffering from lung cancer. Both first-hand and second-hand smoking have also been linked to breast cancer. Apart from trying to reduce emissions to lower air pollution, it is also important to clean filets of air conditions, etc. regularly to lower indoor air pollution. Preventing the smoking of tobacco in public spaces can also help improve air quality.

All pollutants emitted by us eventually find their way into the water we drink. Even if you are not drinking contaminated water, merely, showering or swimming in contaminated water can make your body more vulnerable to the carcinogens in it. Common water pollutants include arsenic, hazardous waste, animal waste, radon, chemicals and asbestos. Drinking water with concentrated amounts of arsenic has been linked to cancer of the lungs, liver, kidney and bladder while the chlorine used to treat drinking water increases the risk of bladder and rectal cancer.

To reduce the risks of cancer caused by polluted water, it is essential to reduce disinfectant by products by keeping water treatment facilities updated and promote green chemistry and alternative assessments to reduce pollution as a whole.

Pollution - How It Has Increased the Risk Of Cancer?

Are you aware of the link between air pollution and cancer? Air pollution refers to the mixture of several harmful substances, which lead to various serious health hazards on exposure. The primary sources of air pollution are man-made, including fumes from automobiles and the smoke from burning fuels. Desert dust, radon gas, and several other natural sources of air pollution are equally dangerous. Air pollution is classified into outdoor and indoor air pollution. It is highly associated with increased risks of developing cancer. Smoking is considered to be one of the major agents, which pollute the air and increase the chances of cancer to a large extent.

Outdoor air pollution

Outdoor air pollution is strongly linked with cancer development.
As every person is exposed to some form of air pollution, it has a more harmful effect on the whole population across the globe as a general threat.
A certain part of outdoor air pollution referred to as PM 2.5, or solid dust particles, are highly responsible for the development of cancer.
The chances of cancer increase with the increase in PM 2.5 levels in the air.
Indoor air pollution

There are several sources of indoor air pollution that are closely associated with an increased risk of cancer.
The sources include fuels used for heating homes and for cooking, radon, and tobacco smoke.
Second hand smoke is another harmful indoor air pollutant that causes cancer.
Second hand smoke

Secondhand smoke increases the risk of cancer development, along with the risk of developing other diseases such as stroke and lung disease.
A lot of people all over the world get exposed to second hand smoke.
A lot of deaths occur due to cancer because of second hand smoke exposure which is common every year, all over the globe.
Radon

Radon is a natural radioactive gas, which is associated with increased risks of developing lung cancer.
It is found at low levels outdoors. It may also build in high concentrations indoors.
Although radon exposure does not pose a huge threat for cancer, a lot of radon-associated cancers develop due to exposure to radon, along with tobacco smoke.
Benzene

This is a flammable liquid having no color and with a sweet odor.
It is closely associated with the development of leukemia and cancers affecting other cells of the body.
Cigarette smoking and tobacco smoke are major cancer causing elements that are found in the air commonly. Both of these are quite harmful. It is recommended that you not only quit smoking, but also keep away from passive smoking.

Pollution and Cancer - How They Are Related?

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. While there is a wide range of treatment options available, the best way to deal with it is to ensure a good diet along with a healthy lifestyle. Here is a list of cancer-fighting food products, which can immensely help to prevent cancer.

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.

World Cancer Day - 5 Amazing Foods That Help Fight Cancer!

Cancer has been regarded as one of the most deadly diseases. It is a non-communicable chronic disorder, caused by uncontrolled growth of cells in the human body. Every year over 7 million people succumb to this disease globally and over 12 million people are diagnosed with cancer. Indian Council of Medical Research (ICMR), estimated that India will observe over 8 lakh deaths and over 17 lakh new cancer cases annually by the year 2020. The survival expectancy of a cancer patient depends upon the stage of diagnosis.

There are some forms of cancer which show any noticeable symptoms only in the final stage while there are certain other subtle symptoms which if paid attention to might save a life.
Some common signs of cancer:

Unexplained weight loss: This is one of the earliest noticeable symptoms of cancer and is particularly common in patients of lung and breast cancer. Weight loss has been observed in over 40% of cancer patients at the time of diagnosis. Losing over 10% of body weight in a span of 6 months or less could be a cause of concern.
Wheezing: This is associated with lung cancer, which is also the most common form of cancer. When the airway in the lungs is pressed or narrowed by a tumor, it creates a wheezing sound while breathing.
Frequent infections: Frequent infections and fever may indicate that something is not right with the internal organs of the body. This could be because of cancerous conditions such as leukemia or lymphoma. 
Loss of appetite: Cancer impacts the metabolic process of the body, hence often leads to a loss of appetite. This is particularly a symptom of colon, stomach, ovaries and pancreatic cancer. 
Blood in stool/urine: Traces of blood while passing stool or urine could be a symptom of cancer. Though, this could be attributed to many other infections and conditions as well.
Chronic cough: Flu and cough along with symptoms like chest pain, hoarseness, weight loss and fatigue could be because of lung cancer.
Night sweats: Though night sweat could be attributed to many more reasons, it is also one of the many early warning signs of cancer.

Early Warning Signs Of Cancer That We Often Ignore!

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!
