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!

As much as you want to avoid, there are things you have no control over. Lung cancer (Bronchogenic Carcinomas) is one such nemesis that can throw life in shambles. The malignant tumor that originates in the lungs slowly spreads onto the other distinct and vital organs as well. Thought to be mostly affecting men who are chain smokers and into severe tobacco consumption, incidences of lung cancer in women are rising at an alarming rate over the past few years. Non-smokers may also be susceptible (to a lesser extent though) to lung cancer.

Lung cancer can be either

Non-small cell lung cancers: The NSCLC, accounting for ~85% of the lung cancer is one of the most common types of lung cancer affecting people, NSCLC may further be divided into
Adenocarcinoma: This type of NSCLC originates mostly in the peripheral regions of the lungs and may affect (spread) the lymph nodes. Non-smokers and women are mostly at the receiving end (other than the chain smokers).
Squamous Cell Carcinoma: Also known as Epidermoid Carcinoma, often affects men, epidermoid carcinoma may originate in the tissues that line the bronchial tubes. The lymph nodes are often affected by Epidermoid Carcinoma.
Large-cell Undifferentiated Carcinoma: The point of origin of large-cell undifferentiated carcinoma is the surface of the lungs. They have a higher probability of spreading to the lymph nodes.
Bronchioalveolar Carcinoma: Though rare, bronchioalveolar carcinoma originates close to the air sacs.
Small Cell Lung Cancer (SCLC, accounting for ~25% of the lung cancer): As the name suggests, SCLC is marked by the rapid proliferation of small cells into large malignant tumors. SCLC can move throughout the body (affecting vital organs).
Radiotherapy to treat Lung cancer:
Radiotherapy plays a pivotal role in the treatment of lung cancer. The radiation therapy is mainly of two types

External beam radiation therapy (EBRT)
Internal radiation therapy (Brachytherapy)
In external beam radiation therapy, high-energy rays are focused on the cancer cells (thereby resulting in the apoptosis of the cancer cells) externally, from outside the body. EBRT is particularly helpful in case of Non-small cell lung cancers.

The EBRT may be of the following types

3D-CRT (Three-dimensional conformal radiation therapy): An advanced radiation therapy, 3D-CRT accurately marks the position of the cancer cells (using advanced computers). The treatment ensures minimum damage to the other healthy cells and tissues (energy rays are directed at the affected cells from different positions).
SBRT (Stereotactic body radiation therapy): This is a radiation therapy used in the treatment of NSCLC, when it is at a nascent stage.
IMRT (Intensity modulated radiation therapy): As the name suggests, in IMRT, the intensity of the radiation reaching the normal tissues and cells can be modulated. Like 3D-CRT, the radiation in IMRT is directed from different angles (for maximum results).
Internal radiation therapy (Brachytherapy): This type of radiation therapy is generally used to deal with lung cancers that tend to block the airways. In this therapy, the radiation process is carried out through a narrow tube, thereby, shrinking and collapsing the tumor.
The effect, dosage, and duration of radiation therapy depend on the stage and severity of the condition. In some cases, radiation therapy may be given together with chemotherapy.

Radiotherapy - Is It Beneficial For Lung Cancer?


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 -  Signs and Symptoms

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.

Know About Laser Prostate Surgery

Radiotherapy is a kind of treatment that kills the cancer cells by using high energy beams. Specialists use radiotherapy to treat a wide range of lung cancer. For early stage lung cancer, the radiotherapy may get rid of the cancer totally. For the small cell lung cancer you may have radiotherapy only. Then again you may have it with another treatment, for example, chemotherapy or surgery.

For small cell lung cancer, radiotherapy is used with or after chemotherapy. Chemotherapy makes the tumor in the lung shrink. You may have radiotherapy to your cerebrum, which tackles any cancer cells that may have spread to the brain. This is called prophylactic cranial illumination (PCI). In case of advanced lung cancer, the treatment contracts the tumor and controls it for a while. It additionally decreases symptoms like shortness of breath.

The types of radiotherapy used for the lungs include:

Outer radiotherapy: This kind of radiotherapy comes from a machine and is administered to the body through an external source. It depends on the kind of cancer and the progression of the same. You may have three radiotherapy sittings every day for around 12 days. This sort of radiotherapy is known as CHART ceaseless hyperfractionated quickened radiotherapy. A few people with small cell lung cancer may have treatment twice a day. If you are getting radiotherapy to control the side effects of lung cancer, you may have a single treatment or day by day medications for up to 3 weeks.



Inner radiotherapy: This is called brachytherapy or endobronchial treatment. This will be administered during a bronchoscopy. The radiation is given through a thin tube that the specialist puts inside your aviation route for a few of minutes. Specialists use this sort of treatment to shrink a tumor that is blocking or pushing your breathing track and making breathing troublesome for you.

These are some of the procedures that take place while you are having lung cancer radiotherapy:

Radiotherapy machines are enormous. The machines are fixed in one position or are sometimes ready to go around your body to give treatment from various angles.
Prior to your first treatment, your radiographers will clarify what you will hear and see. The treatment room normally have docks for you to connect to music players. So you can listen to your own choice of music.
You cannot feel radiotherapy when you really have the treatment. It takes anything from one second to a few minutes. It is essential to lie similarly situated every time, so the radiographers may take a short time to get you prepared.
Once you are in the right position, the staff will allow you to sit in the space for a couple of minutes. They watch you constantly on a closed circuit TV screen. They may request that you hold your breath or take shallow breaths during the treatment.
In case you have a concern or query you can always consult an expert & get answers to your questions!

Radiotherapy For Lung Cancer!

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.
