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?

Cancer like most other diseases has the best rates of recovery with early detection and intervention. As there are no regular health screenings for blood cancer, only the awareness about the early warning signs can save your life. November is designated as the Lung Cancer Awareness Month, to ensure every individual is equipped to fight against lung cancer right from the start. Here are 4 vital facts you must know to win your fight against blood cancer.
Lung cancer is also known as pulmonary carcinoma or cancer of the lung. It occurs when DNA mutations develop in the cells/ tissues of the lungs leading up to uncontrolled growth in the tissues of the lung. By far, it is known to be the most common cancer in Asia.

1. Type: lung cancers can present as one of the following types: 

Non-Small Cell Lung Cancer (NSCLC): Most common type of lung cancer and constitutes nearly 85% of all lung cancers. The sub-types of NSCLC are as follows:
Large cell carcinoma
Squamous cell carcinoma (SqCC) (Epidermoid)
Adenocarcinoma   accounts for majority of the NSCLC.
Small Cell Lung Cancer (SCLC): It is also known as oat meal cancer and tends to spread (metastasize) quickly. This constitutes about 15% of the lung cancers.
Mesothelioma: It is a rare cancer that develops in the mesothelial cells of the pleural or peritoneal surfaces. It usually arises in the pleural membrane lining the lungs, known as pleural mesothelioma. One that arises from the peritoneum is called the peritoneal mesothelioma and the one that arises from the pericardium is known as pericardial mesothelioma. Lastly, it can also arise from the tunica vaginalis known as testicular mesothelioma. People working with or prior exposure to asbestos are mostly at risk of developing mesothelioma. The latency period between time of exposure and development of mesothelioma can be somewhere between 20 to 40 years. Maximum of the patients who develop mesothelioma are men.
2. Gender: It affects the male populace predominantly. It is more common in men than in women and in those of lower economic status. However, the incidence of lung cancer, in women too, is on the rise of late.

3. Etiology: Cigarette/ Tobacco smoking remains the most important cause of lung cancer accounting for 85   90% of the cases. Incidence/ risk is proportionate to the number of cigarettes smoked irrespective of the age. Also, environmental toxins including smoke from burning black tar, exhaust gases from automobiles etc. too contribute actively to various lung diseases including cancer. People working in asbestos manufacturing factories who are exposed to asbestos dust are also likely to get lung cancer. Tuberculosis too is an additive risk factor. Again, people who have received ionizing radiation especially to treat Hodgkin Lymphoma or other malignancies also run the risk of developing lung cancer. Above-mentioned causes apart, genetic factors may also play a role.

4. Features: Lung cancer clinically presents in the following ways mainly. Signs & symptoms of malignant mesothelioma are as enumerated below

Difficult/ labored breathing (Dyspnea)
Chest pain
Palpable chest wall mass
Discordant chest wall expansion
Weight loss (Cachexia)
Loss of appetite (Anorexia)
Night sweats
Signs & symptoms of non-small cell lung cancer (NSCLC) are as enumerated below. Majority of patients are symptomatic at diagnosis

Chronic cough
Difficult/ labored breathing (Dyspnea)
Chest pain
Blood stained sputum (Hemoptysis)
Hoarseness
Weight loss (Cachexia)
Loss of appetite (Anorexia)
Weakness
Bone pain
Pleural or pericardial effusion
Superior vena cava syndrome
Brachial plexopathy
Neurologic pain
Hypercalcemia of malignancy
Signs & symptoms of small cell lung cancer (SCLC) are as enumerated below

Symptoms as per the points 8   18 depicted above for NSCLC are applicable for SCLC as well. Additionally, patients suffering from SCLC may have:

Fever associated with chest infections like bronchitis/ pneumonia that refuse to go away or keep coming back
Horner syndrome
Paraneoplastic syndromes including encephalitis/ sub-acute sensory neuropathy, hyponatremia, acromegaly, cancer associated retinopathy, ectopic corticotropic syndrome etc all.
5. Screening: is generally recommended for asymptomatic/ symptomatic populations as surveillance for high-risk individuals   who are either current or former smokers (quit smoking within the last 15 years) have at least a 30 pack-year smoking history and those who do not have any prior history of lung cancer. The goal of screening, as usual, is to be able to detect & diagnose lung cancer at an early stage which is potentially curable. It is mostly radiologic with a low dose helical computed tomography (CT) scan being more effective in detecting early-stage lung cancer than a chest radiograph can.

6. Diagnosis: Abnormal blood test results may be indicative of malignancy, but a follow-up imaging/ biopsy is always the gold standard for an accurate diagnosis. Following are the diagnostics employed mainly:

Blood: Hb may be low, TLC, ESR and polymorphs increased. Adenocarcinomas are likely to express thyroid transcription factor 1 (TTF-1) or carcinoembryonic antigen (CEA). On the other hand, mesotheliomas are likely to express Wilms Tumor -1 (WT-1) protein and Calretinin.
Imaging: Thoracoscopy, Bronchoscopy, X-Ray, CT Scan etc all. Positron Emission Tomography (PET) / CT scan and Magnetic Resonance Imaging (MRI) scan help detect metastasis if any.
Biopsy: It clinches the histologic diagnosis and the nature of the disease.
7. Treatment: Conventional treatment includes surgery, chemotherapy and radiotherapy as contextually appropriate. Simultaneously, an adjunctive or integrative naturopathic treatment with suitable complementary & alternative medicines (CAM) too can help improve clinical outcomes and facilitate recovery as would be feasible contextually.

8. Prognosis: Preventive measures, earlier diagnosis and right early treatment are key for effective therapeutic management & better prognosis. Like most other cancers, the chances of cure for early-stage lung cancer are more. The cure/ recovery chances are influenced by the grade, stage of cancer, recurrence and the patient s general health & vitality etc all. The primary determinant of prognosis in NSCLC is the stage at which the cancer is diagnosed. For non-metastatic cancers, however, it is the nodal status that determines the stage and hence the prognosis.

9. Prevention: Rightly said, prevention is always a better choice. Cigarette smoking is to be avoided by all means as it is the single major cause of lung cancer. Even exposure to cigarette smoke (passive or secondhand) is also an established cause of lung cancer and is known to increase the risk of lung cancer in non-smokers as well. Preventing exposure to secondhand smoke can be helpful in decreasing the incidence and mortality of primary lung cancers. Above-mentioned apart, other important risk factors such as exposure to ionizing radiation, environmental carcinogens like smoke from burning black tar, exhaust gases from automobiles, outdoor air pollution, and occupational exposure to asbestos, arsenic, beryllium, nickel, cadmium, chromium etc all too are known to increase the risk for lung cancer and mortality thereof. In fact, cigarette smoking is known to potentiate the effect and hence the lung cancer risk of many of the above-mentioned carcinogens, multi-fold, in smokers. Thus, either eliminating or reducing the exposure to the above-mentioned carcinogens can lead to a decrease in the risk of lung cancer and incidences thereof. Furthermore, randomized clinical trials indicate that high-intensity smokers (only) who take supplementation of beta-carotene have an increased risk/ incidence of lung cancer. Vitamin E supplementation, on the other hand, does not affect the risk of lung cancer as indicated by the trials.

Lung Cancer Awareness Month - Lung Cancer In Nutshell!

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.

International Childhood Cancer Day is celebrated annually on 15 February to raise awareness and to express support for children and adolescents with cancer, survivors and their families.

Why is Cancer the biggest Threat to the YOUNG in India?

There are fewer Indians who have successfully battled Cancer and have emerged successful. Yuvraj Singh, the legendary cricketer, who was diagnosed with a rare cancer at 29, survived due to an early detection. Cancer cases in India are not as many as they are in the developed world. However, due to late detection the survival rate in the country is far worse. Particularly, we are losing our youth to Cancer. Most tobacco (pan masala) related cancers and child cancers go undetected until very late.

Few cancers like cervical cancer and breast cancer which affect women of any age, are curable, however, due to lack of awareness and timely screening, many Indian women succumb to these cancers. The most common sites for cancer among men are lung, prostate, colon, rectum, stomach and liver while that among women are breast, colon, rectum, lung, cervix and stomach.

In proportion to our population, we lack the right infrastructure nationwide. esp in the northern and north eastern region, there is a dearth of good cancer facilities, where radiation, care or treatment can be given. Not even one third of cancer patients are alive beyond 5 years after their diagnosis in India, and about 71% of cancer deaths occur in patients in their prime productive years   between the ages of 30 to 69 years.

 Most Indians believe that cancer is generally incurable and that it should be kept secret from neighbors and family.  -  Dr Paul Goss, MD, Harvard University.

All these factors have contributed to a very high mortality rate. No wonder Cancer is dreaded in the country. Investment, infrastructure, lifestyles as well as mindsets need to change if we were to contain the Cancer mortality rate. While you need to watch out for early signs of cancer, here are the lifestyle changes every individual esp. all youth must adopt to avoid cancer.

Avoid Tobacco - both smoking and chewing.

Reduce alcohol intake - Save your organs from deteriorating.

Limit UV ray exposure from the sun - Keeps your skin safe.

Maintain a healthy diet - Include foods rich in Vitamins, minerals and fiber which nourish your body and build immunity.

Increase your level of fitness - Maintain a good bodyweight. Additional flab invites a host of troubles, that includes variety of cancers.

Seeking regular medical checkup or screening - This is the only way to prevent and get detected early on.

International Childhood Cancer Day - Why Cancer Is A Threat For Young?

Pulmonary diseases are some of the most commonly experienced health conditions all over the world. Millions of people suffer due to various causes including genetics, smoking, pollutants and infection. Now lungs are one of the most important and complex organs of the body. They are the apparatus through which oxygen enters and carbon dioxide gets expelled. 

Lungs expand and contract on a constant basis to ensure that we can breathe properly. Let us find out more about lung or pulmonary diseases.

Asthma: This is one of the most common and potentially fatal conditions that affect children and adults. It grips the airways formed by the bronchi which branch off into smaller tubes from the main trachea that holds them. This condition causes inflammation, and even spasms, which can lead to wheezing and breathlessness. The main triggers of asthma attacks include allergies, infections and pollutants that may escape into the airways.
COPD: This is also known as Chronic Obstructive Pulmonary Disorder. It is an umbrella term used for various lung conditions that cause breathing difficulties due to an obstruction of the airways. Chronic bronchitis is one of the conditions that falls under COPD, and is usually characterised by persistent, hacking coughs.
Cystic Fibrosis: This is another condition that affects the airways by causing poor passage of mucus from the bronchial tubes. This condition is a genetic one where the mucus that gathers eventually becomes a lung infection.
Pneumonia: This is a condition that causes an infection in the alveoli, which are the tiny tubes that the airways branch into. These are air sacs that can catch myriad infections like pneumonia.
Tuberculosis: This is also a kind of pneumonia, which is caused by bacteria called Mycobacterium Tuberculosis. This condition usually attacks the air sacs of the lungs and can be a potentially fatal disease if it is not treated on time. The patient will require immediate hospitalisation.
Pulmonary Edema: This condition is caused by fluid leaks from the tiny blood vessels into the surrounding air sacs within the lungs. It can also be caused due to heart failure as well as back pressure which falls on the lungs. Direct injury to the lungs can also lead to this condition.
Lung Cancer: This is a fatal disease which can be found in any part of the lungs. It has many forms and the type as well as the location usually determines the kind of treatment option that will be followed.
Acute Respiratory Distress Syndrome: When the lungs suffer a sudden injury which is usually caused by a bout of serious illness, it is called ARDS. Treatment involves the use of life support ventilation.

All About Pulmonary Diseases

Prostate cancer is a cancerous tumor in a man s prostate gland, a small gland that is responsible for producing the seminal fluid which transports and nourishes the sperm. It is a very common type of cancer among men. A few cases of prostate cancer tend to develop slowly while others may progress very fast.
Symptoms-
In the initial stages, prostate cancer may not show any symptom. However, in the latter stages, there may be symptoms such as:
Pain in the bones.
Erectile dysfunction.
Urination can get troublesome.
Presence of blood in the semen.
Pain and discomfort in the pelvic region.
Causes-
The exact causes of prostate cancer are not known. It starts to develop when certain cells in the prostate gland start to mutate. These mutations cause these cells to multiply at a very fast rate and thus, soon form tumors. Although the causes are not known, certain factors tend to aggravate this condition; them being:
Color: According to certain medical reports, a darker skin may mean increased chances of suffering from prostate cancer.
Age: The risk of developing prostate cancer tends to increase with age.
Genetics and Family History: Faulty genes could be another cause of this condition. Also, having some member in the family who is diagnosed with this type of cancer only increases the risks of you suffering from them.
Obesity: If you are obese, then you are more likely to develop prostate cancer.
Treatments-
The treatments for prostate cancer include:
Radiation Therapy: In this procedure, high energy rays are used to target and destroy cancer cells. Usually X-rays or protons are used to treat the cancer cells.
Hormone Therapy: Hormone therapy is a type of treatment wherein certain medications are administered to prevent your body from producing testosterone.
Surgery: If the other treatment methods do not produce desired results, then a surgery is carried out for the removal of the prostate gland. In addition to the prostate gland, some adjoining lymph nodes and tissues are also removed.
Chemotherapy: Chemotherapy is method of destroying cancer cells by injecting chemicals into the body. The medicines are injected into the veins in the arms.
