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!

Medical science constantly challenges the boundaries by finding not only the cures to the most dangerous diseases, but finds a way to prevent them even before they occur. With years of research, practice and data available for analysis, scientists are using advanced technology in combination with years of research to create a predicting mechanism for often fatal diseases like cancer.

Breast cancer screening has always been done with mammography. The fact is that this method is only 75% accurate, laden with false positives and misses a whole set of women totally- and that too when cancer has already developed. Part of the problem comes from the dense breast tissue which one in three women have. This tissue masks the lumps, which makes it difficult for mammograms to accurately screen cancer.

Some breakthrough scientific methods are changing this by drawing on years of research to predict this deadly disease, years before it can manifest itself.

A genetic test to predict cancer 10-11 years ahead of time
This test was performed to see how environmental factors could influence cancer, along with habits like smoking, abusing alcohol or hormones, genetic changes that occur and are put a large percentage of the women at a high risk of developing this disease.

A simple blood test is used for the genetic analysis of hereditary cancer. Researchers found a biological marker, methylation of the ATM gene, which has a very high ability to predict the risk of developing cancer, several years before diagnosis. 'Methylation' concluded that when one biological indicator is exposed to carcinogenic substances, or other abusive substances like tobacco and alcohol, it may trigger the development of cancer. On the flip side, this test will take time to reach the commercial market and even then cannot give an exact timeline as to when someone may develop the disease.

A simple blood test to predict breast cancer 5 years before it develops
This is the kind of medical miracle the world is looking for. Last year in April, researches in Denmark identified a simple blood test that can predict breast cancer five years before it actually develops with an accuracy of a whopping 80%.

It works by "measuring all of the compounds in the blood to build a 'metabolic profile' of an individual, in order to detect changes in the way chemicals are processed, during a pre-cancerous stage," says Laura Donnelly, health editor at The Telegraph, which covered this development. Danish researchers observed 57,000 participants over 20 years, gathering blood samples along the way, specifically comparing a set of 800 women who remained healthy or developed breast cancer within 7 years of their first blood sample. The researchers found they were able to predict, with 80 percent accuracy, which patients would be affected by the disease, just by looking at the metabolic profiles they built from the participants' blood samples. The results have been published in Metabolomics.

Can Breast Cancer Be Predicted Before It Develops?

The incidence of pain and lumps in the breast is on the rise. Breast cancer has grown in incidence over the years. More women are getting diagnosed with it, and the age at which they are being diagnosed has reduced too. Therefore, preventative checks and screenings have gone up significantly. The number of women diagnosed with small lumps has gone up drastically. The good thing is that since these are diagnosed in the early stages, the treatment is simpler and the prognosis far better than women who get diagnosed much later in life.

In a majority of cases, once a lump is identified the most preferred treatment is removal. This is known as lumpectomy. However, before a final decision is made to remove the lump, there are certain tests that are run by the doctor to confirm the diagnosis and extent of spread.

A thorough breast exam to identify if this is an isolated lump or if there are more lumps in either breast. The exact shape and size of the lump also need to be identified so that treatment can be planned accordingly.
Imaging to see if the lymph nodes have been involved. In most cases, there could be spread to the lymph nodes in the armpits which also need to be removed if required. If the lump is too big or too many in number, then a mastectomy may be required instead of a lumpectomy. This requires removal of the entire breast tissue on one or both sides (rarely) along with involved lymph nodes.
Pre-surgery: Once the diagnosis is confirmed, then the doctor will plan treatment. Prior to the surgery,

Talk to your doctor about your other medical conditions and medications and allergies, if any
Gynecologic history is very important to be discussed in detail
Blood thinners have to be stopped prior to the surgery
Post-surgery care needs to be planned, including a caretaker for a few days and postop care
During surgery:

Lumpectomy or mastectomy is often done under general anaesthesia
This requires hospitalization and carries the risks associated with anaesthesia
The outlined breast tissue or complete breast and surrounding lymph nodes will be removed. The area will be closed using sutures and bandaged
Post-surgery:

The wound needs to heal, and so postop care is very important
For the first few days, painkillers and antibiotics are used to control pain and infection
As a follow-up, some women may require radiation therapy to contain the suspicious tissue that may be left behind after lumpectomy
If extensive breast tissue was removed, some women may prefer to have reconstructive surgery done
Remember that lumpectomy is not a definitive procedure, and there could be cases that require a repeat operation
Advantages:

Less invasive compared to a mastectomy
The appearance of the breast is minimally affected, and symmetry is maintained
Disadvantages:

May not ensure complete removal
May require additional radiation therapy
May require repeat surgery

Surgical Treatment For Pain And Lumps In Breasts Of Women!

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 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!

A breast lump is a restricted swelling, projection, lump or knot in the breast that doesn't feel like a breast tissue. There are diverse reasons why breast lumps occur.

Not all lumps are cancer. These can also be breast conditions that are not harmful and which can be easily curable.Knots that feel harder or are not the same as the rest of the breast need to be checked. This kind of irregularity might be an indication of breast cancer.

A self-examination should be your starting point. This is how you can detect a lump on your own:

Step 1: Begin by taking a look at your breast in the mirror. Keep your shoulders straight and your arms on your hips.

This is what you need to search for:

    Breasts that are their typical size, shape, and shading
    Breasts that are uniformly formed without distortion or swelling

In the event that you see any of the changes mentioned below, convey them to your doctor:

    Dimpling, puckering, or protruding of the skin
    A nipple that is not in its initial position
    Redness, rash or swelling

Step 2: Now, raise your arms and look for the changes mentioned above.

Step 3: While you're in front of the mirror, search for any indications of liquid or blood discharge from the nipples.

Step 4: Next, examine your breasts while resting.Use Your right hand to feel your left breast and use your left hand to feel your right breast. Cover the whole breast from your collarbone to the highest point of your mid-region, and from your armpit to your cleavage to search for any lumps.

Step 5:Examine your breasts while either standing or sitting. Many women find that the easiest approach to examine their breasts is when their skin is wet, so this step could be done while taking a bath as well.

Diagnosis:

    Mammogram: Mammography is a technique using X-rays to diagnose and locate tumours of the breasts.
    Breast ultrasound: Breast ultrasound utilises sound waves to create pictures of the breasts from the inside.
    Breast MRI:This involves using an effective and attractive field, and radio frequency pulses to create photos of the insides of the breasts.
    Ultrasound-guided biopsy: During this sort of biopsy, utilising ultrasound imaging to discover the bump, a radiologist will give you anesthesia and afterward insert a needle into the lump to evacuate some tissue for assessment under a magnifying lens. Stereotactic biopsy and an X-ray-guided biopsy may also be used.

Possible treatments:

    In case the knot turns out to be cancerous, surgery is typically performed.
    You may have a few discussions with different doctors for additional treatment, including radiation treatment and chemotherapy or hormone treatment.
