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!

One of the most common issues with old age in men is the enlarged prostate. Any difficulty with urination (no constant stream, difficulty initiating, or incomplete emptying of the bladder for instance), and the first suspect is an enlarged prostate. These symptoms are followed by a digital rectal exam to check for an enlarged prostate. Once confirmed, the next step is to check for levels of prostate-specific antigen (PSA). If both the exam and the PSA are positive, it could mean prostate cancer. As with any cancer, it is believed that sooner it is diagnosed and the treatment is started, the better.

Historically, the best way to rule out the prostate cancer had been to do a prostate biopsy. This is a minor invasive procedure, wherein biopsies are taken from various regions of the prostate which are known to develop cancer (about 12). A disadvantage of this procedure includes missing out on the front part of the prostate which can also develop cancer. Secondly, it is not a very pleasant experience and given a chance, most men would not want to have it done.

There is good news for these men who would like to avoid prostate biopsies. The first is the multiparametric MRI which uses no x-rays and is considered very safe with extremely accurate results. This MRI exam requires about an hour, and once the images are obtained, the doctor will analyse these images and check for several parameters to assess for prostate cancer. The absence of cancer can be confirmed with up to 90% accuracy, which is far greater than with usual biopsies. If there is a possibility of cancer, then a biopsy can be done to confirm it. 

Also, these images indicate the exact region where cancer likely is, and this guides the doctor to biopsy only where absolutely essential. The chances of false positive and false negative results are reduced drastically. The one disadvantage here is that MRI detected biopsies usually tend to be of a higher grade which requires immediate treatment.

Another way to reduce chances of the biopsy by 30% to 50% is by the 4K test. It helps detect a variety of prostate issues including cancer. It can be used once higher levels of PSA is identified and before going for a biopsy. It combined 4 prostate-specific biomarkers with clinical information to accurately provide men with a risk of developing prostate cancer. It can be used even after negative biopsies to confirm the diagnosis of prostate cancer.

These two measures can drastically reduce the incidence of prostate biopsies, which is neither pleasant for the patient nor very effective for the doctor.

Prostate Biopsies - Ways You Can Avoid It!

Benign prostatic hyperplasia or BPH is a condition where the prostate gland gets enlarged. This is mostly common in men who are ageing. When the prostate gland gets enlarged, the flow of urine through the urethra gets blocked, and hence, several problems related to urination may occur. BPH occurs as a result of hormonal imbalance. If untreated, BPH can lead to severe bladder and urinary health conditions.
There are several symptoms and signs of benign prostatic hyperplasia. Here are 7 common symptoms:

1. A frequent need for urination: Men affected by BPH feel an increased need to urinate frequently. This gets enhanced during the night and is called nocturia. The patient may even need to urinate more than eight times a day. Due to the enlarged prostate gland, more pressure is put on the urethra, which leads to uncontrollable urination.
2. Urinating difficulties: The act of urination becomes difficult. Because of enhanced pressure on the urethra, the flow of urine to the penis from the bladder gets blocked. This makes a urine stream hard to start. The urine stream gets weak and interrupted, and more difficulty may be experienced during the end of urination.
3. Pain during urination and ejaculation: Due to pressure on the urinary tract and reproductive system, pain can accompany urination and ejaculation. Some patients tend to push urine out, which results in pain. The pain may also occur because of infection during BPH.
4. Blood in urine and an unusual color/smell: Urine may take a dark color and have an unusual smell due to urinary retention. Unpleasant urine smell signifies urinary tract infection. Blood in the urine may also result because of dilated veins present on the surface of the enlarged prostate.
5. Urinary retention: When a patient is unable to pass any urine, it is called urinary retention. Such a condition requires immediate treatment, and you need to consult a doctor immediately.
6. Urinary tract infections: Bacteria may start growing in the bladder when the bladder is not fully emptied of urine. This bacterial infection causes darkening of the urine, and emission of a foul odor.
7. Bladder stones: Bladder stones may develop because of the inability of the bladder to empty itself completely. This is a major symptom of BPH. Hard lumps of minerals or bladder stones are formed when the urine present in the bladder gets highly concentrated, which causes the crystallization of minerals. Bladder stones may cause infections, result in blood in urine, cause bladder irritation and may also block urine flow.

So you see that benign prostatic hyperplasia involves the enlargement of the prostate gland, and results in several problems related to urination and different symptoms. Hence, immediate treatment is advisable.

7 Symptoms of Benign Prostatic Hyperplasia

The most dreadful part of getting to work and getting back home in the evening is the being stuck in a traffic jam. Whether you re driving yourself or being driven home, a traffic jam can sap your spirits and make you feel tired even though you re not really exerting yourself. According to a recent study, these traffic jams not only increase your stress levels, but also make your body susceptible to cancer.

Yes! They can be a major reason behind your ill health-

Bumper to bumper traffic that moves at snail pace can be very stressful, especially if you have to get somewhere at a particular time. The irritation of not being able to move at your desired pace adds on to the million other things going on in your mind. The body reacts to stress by increasing blood sugar and blood pressure levels. Long term stress can lead to digestive problems, fertility issues and a weakened immune system that makes the body vulnerable to other diseases and infections. Stress can also lead to the development of behavior like smoking, drinking and over eating which can increase a person s risk of cancer.
Pollution levels are highest at traffic signals and at traffic jams. This is because at a busy intersection, cars go through various stages such as accelerating, braking and idling in a restricted space. Each of these actions is accompanied with emission of toxic gases and fine particles of matter which concentrate in an area and take longer to disperse. Contrary to popular belief, people in cars can be more affected by these pollutants than pedestrians. This is especially true in cases where people have their windows up and fans on as the fans suck in polluted air leading to a buildup of toxic gases inside the car. When these gases and particulate matter are inhaled, they get stuck in the nose and throat and are absorbed into the blood stream. Long term exposure to this can have serious negative effects on the body including a higher risk to cancer. To avoid this, ensure that the setting of the ac of your car or fan is set to only circulate air inside the car without drawing in polluted air from outside.
Also, try and find ways to avoid traffic jams. If your office allows, maybe you could try changing your timing a little. Experiment with routes. Often the inner roads have more twists and turns but much less traffic.


Traffic Jams - Can they Make Your Body Susceptible to Cancer

Prostate Cancer -  Signs and Symptoms


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.
