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 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!

Melanoma is a condition which mainly indicates a severe malfunction of the melanocytes or the melanin producing cells of the body. These cells are responsible for giving you your skin colour, tone and complexion. Usually, a person suffering from melanoma will have many normal and irregular moles as well as melanoma in the eye and digestive tracts too.

Some general facts on melanoma are mentioned below:
Melanoma is common in young women and causes many deaths.
More than one million new instances of skin cancer or melanoma are analyzed every year.
There has been a 2000% increase in rate of melanoma since the year 1930. One out of fifty get affected by this cancer.
There has been a high rise in the rate of melanoma from 1970 to 2008. There has been an 800% increase in young women and 400% increase in case of similar aged men.
Early recognition makes melanoma treatable. It is screened for growth very minimally.
Primary causes Melanoma may be caused primarily due to these causes:
The most primary cause of melanoma is ultraviolet light (UV) in people with a low level of skin pigment. The UV light might be from either the sun or from different sources, for example, tanning devices. Around 25% of cases occur from or in the form of moles.
The individuals who work on airplanes seem to have an expanded danger, due to more contact with UV rays.
Ultraviolet UV light of wavelengths between 315 - 280 nm from the sun react with the skin cell DNA and result in a kind of direct DNA harm called cyclobutane pyrimidine dimers (CPDs).
In order to stay away or avoid melanoma, you should:
Avoid the sun at peak hours.
Examine your skin at times for some kind of change.
Keep away from tanning salons.Melanoma is a dangerous form of cancer and causes a lot of deaths. You should stay away from anything that causes melanoma.


All About Melanoma

Breast examination is a way of detecting early changes that help in detecting lumps or other growth in the breast. This is a manual form of examination that may be carried out by the doctor or even by the patient. This kind of examination helps in detecting the onset of breast cancer and helps in successful treatment of the same. It is an essential screening strategy that all women must go through. Let us cast a glance on the various details regarding this examination, and also how frequently it must be conducted.

Age: Women who have reached the age of 18 are said to have matured physically and sexually. They should perform this examination once they have reached the said age in order to detect any anomalies in the way the physical changes occur in the breast tissue.
Procedure: One should begin by looking at one's reflection in the mirror to find any rashes or dimpling in the breasts. The shape, size and colour of the breasts and nipples must also be studied so as to check for any anomalies. Inverted nipples, redness and soreness must also be reported to the doctor. Once you are done checking the visuals, you can raise your arms and look for any changes. Then, you will need to lie down and feel your breasts by using a circular motion. The finger pads must be used in order to check for any lumps. One must start from the centre and move the breasts sideways. Any wet and slippery feeling must be reported to the doctor immediately.
Pressure: During the breast examination, you must use light pressure for the skin and tissue that lie beneath the breasts, while medium to moderate pressure should be used for the middle portion of the breasts. One must use a firm hand to check the tissue that lies at the back of the breasts, near the rib cage.
Frequency: One must get into the habit of conducting a breast examination at least once a fortnight or once a month, without fail. You can also go to the gynaecologist for an examination in case you are not confident of conducting it on your own with proper movements and accuracy. You may also journalise your breast examination findings.
Menstrual Cycles: When you are going through your menstrual cycle or period, it is important to remember that your breasts can become tender just before or after the start of the cycle. So, do not panic if you think you have found a lump or any other growth at this time. It is best to check again after a week and then visit the doctor about checking the same.

How Frequently Should a Breast Examination Be Done?


Feeling a lump on your breasts can be a terrifying moment. 'Cancer' is the first thing that comes to mind but in reality, most lumps in the breast are not caused by cancer. Apart from cancer, breast lumps can be caused by non-cancerous growths, injuries and infections. The only way to correctly diagnose the cause of a lump in the beasts is through a biopsy. Hence, this is the first step towards treating a breast lump. From here on, treatment will depend on the cause identified.

Mastitis or Breast Infection

Mastitis is a painful infection of the breast tissue often faced by women who are breastfeeding. It can be treated with heat treatment and antibiotics. Massaging the breast while taking a warm shower or applying a warm compress. This will open up the milk ducts and should be followed by nursing the baby or using a breast pump to relieve the swelling and pain.

Abscess

Antibiotics are the first line of treatment against an abscess but this is effective only if given in the initial stage of the infection. In later stages, an abscess will need to be surgically drained.

Fibroadenomas

This is a non-cancerous tumour often found in young women. It is often difficult to distinguish between a Fibroadenoma and a cancerous tumour and hence these are usually surgically removed.

Fibrocystic Changes

In some cases, the breast itself is composed of knotted, rope like tissue. This is known as having fibrocystic breasts. If a new lump presents itself on fibrocystic breasts, a mammogram and an ultrasound are performed to evaluate the lump. In most cases fibrocystic changes do not require any medication or surgery.

Breasts Cysts

Cysts can be defined as fluid filled lumps. In some cases, these cysts become apparent at the time of ovulation and disappear after the period. In other cases, it may need to be drained with a thin needle. Cysts often recur and need to be re-drained.

Fat Necrosis and Lipoma

Fat necrosis is a lump caused by an injury to the fatty tissue in the breast. Lipoma is a fatty growth within the fatty tissue. In both these cases, no treatment is required but if it causes any problems, it can be removed.

Breast Cancer

If the biopsy reveals the presence of a cancerous tumour, you must immediately consult an oncologist. Treatment options for breast cancer include chemotherapy, radiation, surgery and hormone treatment.

Treating Lumps and Pain in Breasts of Women

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.
