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!

Skin cancer most often develops on skin that has faced sun exposure. At the same time, it can also affect skin areas that haven't been exposed to sun's rays. Do you know, skin cancer can be prevented by consuming some foods? Yes, and there are some out there:

1. Fatty fish - Including fatty fish in your diet can shield you against melanoma as they contain the beneficial nutrient Omega-3 fatty acids. In fact, these kinds of fatty acids are considered to be best for consumption as unlike saturated fats, they don't increase your risk for certain types of cancer. A study in the International Journal of Epidemiology reveals that individuals who consume a diet containing fish that is high in these healthy fats have low rates of this form of cancer.
2. Vegetables - This is another food option that is known to possess strong skin cancer-fighting properties. Dark leafy veggies like spinach, kale and broccoli can aid fighting against melanoma. A pigment found in tomatoes called lycopene has properties that guard you against cardiovascular diseases as well as cancers of all kinds. Similarly, the pigment carotenoids found in vegetables like carrots, sweet potatoes, etc are known to protect against sunburn.
3. Herbs - Including herbs in your diet can help in replenishing the minerals and vitamins that get depleted due to the action of the sun. According to experts, about 80% of your body's vitamin levels see a reduction when you stay under the sun for 30-45 minutes. Basil, parsley, and rosemary are a few of the herbs that possess cancer-fighting qualities.
4. Flaxseeds - The unique qualities of flaxseed make it the best option against skin cancer. It contains both antioxidants and omega 3 fatty acids, making it an all-around solution to fighting skin cancer.

4 Foods That Help Fight Skin Cancer

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?

According to a major study that provides a connection between height and cancer, it is stated that taller people are more prone to developing cancer. Research has found that the risk of developing any kind of cancer in women rises by 18% for an increase of every 10 cm in height. In men, the risk rises by 11%, even though height is not as major a factor as are obesity, smoking and a bad, unhealthy diet.

Several reasons have been put forward for the above statement. One of the reasons is that the number of body cells in taller people is more than people with average height. This leads to an increase in the number of cells which could potentially turn malignant.

While individually analysing the impact of height on different cancer forms, it was found that the highest increase in risk was in skin cancer (30% for every 10 cm increase in height), while a 20% increase was noted in taller women developing breast cancer.

Development of cancer in regions including the colon and rectum is known as colorectal cancer. Long legs have been surprisingly associated with this form of cancer. In comparison with shorter people, it was reported that taller people had a higher risk percentage of developing colorectal cancer. Two hypotheses regarding the formation of colorectal cancer have been developed. One hypothesis is that taller people have longer colons, which in turn result in more surface area where colon cancer can develop. The other hypothesis is that taller people experience increased levels of growth hormones. These particularly affect the length of their legs. The growth hormone called 'insulin-like growth factor 1' is increased during puberty and is considered to be a risk factor for colorectal cancers occurring at later stages.

Being Taller Increases Your Risk of Cancer!

A gland that produces a liquid which mixes with sperm and is ejaculated as semen during sexual activity, is the prostate gland and is located under the bladder of a man. Cancer in the prostate is one of the most common cancers that occur among men.

The risk of developing prostate cancer increases progressively with age. Although there is no absolute prevention of prostate cancer, evidence and doctors suggest that a healthy diet can play a key role. Here are a few tips that can go a long way in prevention of prostate cancer:

Red Foods: Tomatoes, carrot, watermelon, and other red foods get their bright color from a powerful antioxidant called lycopene. Studies have proved that by having fruits that contain lycopene, you can reduce your risk of prostate cancer. Some findings suggest that cooking tomatoes make it easier for your body to absorb this antioxidant.
Fruits and Vegetables: Green vegetables contain compounds called carcinogens, which help your body in breaking down cancer-causing substances. Spreading of cancer can be slowed down through a nutrient-rich diet. Avoiding processed junk food and eating fruits and vegetables containing nutrients and vitamins may lower the risk of getting prostate cancer.
Feast on Fish: Fatty acid, also known as omega-3, is found in certain fish including sardines, tuna, mackerel, trout, and salmon. This may help in reducing the risk of developing prostate cancer.
Soy and Tea: Some studies suggest that men who drink green tea or take green tea extract supplements have a lower risk of developing prostate cancer. Many soy products and other foods contain a nutrient called isoflavones, which has been linked to a reduced risk of prostate cancer.
Coffee: Studies show that drinking three cups of coffee a day can reduce the chances of prostate cancer by 11 percent. There is a dose-response relationship between coffee and prostate cancer. The effects of prostate cancer go up or down with the amount of coffee you take. Someone who grabs an occasional cup only, may not have these effects. However, high doses of caffeine can result in major health issues.
Fat: Studies indicate that animal fats and an increased risk of prostate cancer are linked. It is advised to replace animal-based fats with any kind of plant-based fat. In addition to this, overcooking the meat produces carcinogens, therefore it is suggested to be strictly avoided.
Quit Smoking: Smokers are more likely to have an aggressive form of prostate cancer. The chances of a recurrence of the disease are more for people who smoke. It is never too late to quit smoking.
Exercise: Regular exercise and maintaining a healthy body can help you to increase your muscle mass and metabolism. Too much fat in the middle of your body is linked to an increased risk of prostate cancer. You can try walking, running, bicycling or swimming to reduce the weight to lead a healthy life.
It is important to look after yourself and start taking essential steps to prevent prostate cancer rather than trying to manage it once you get it.

8 Easy Ways By Which You Can Prevent Prostate Cancer!

With the recent number of breast cancer cases on the rise, it is important that we should get the examination done on a regular basis as a preventive measure. Even if someone is suffering from it, it is important that we should make an effort and learn about.

If you have breast cancer then a surgery will be part of your treatment. Based on the condition, surgery will be carried out due to any of the following reasons:
1. To remove the cancerous tissues from the breast
2. To reconstruct the breast once the cancer is removed
3. To check whether the cancer has spread to the lymph nodes below the arm
4. To treat symptoms of cancer that has progressed to an advanced stage

Breast cancer surgery may be classified into two types
1. Mastectomy: Mastectomy involves removing the entire breast; tissues in the adjoining region may also be removed. A double mastectomy is a procedure where both the breasts are removed.
2. Breast-conserving surgery: In this surgery, only parts of the breast affected by cancer are removed. The area of the breast that is to be removed will depend on the severity of the cancer. Some healthy tissues may also be removed in this surgery.

Usually, if a woman is in the initial stages of cancer then she may opt for the latter as it entails removing parts of the breast. They may also undergo radiation therapy along with these surgeries.
For checking if the cancer has spread to the lymph nodes below the arm, the lymph nodes are removed from the body. Once they are removed, they are studied under a microscope to check if it has spread, if yes then the extent of their damage. This procedure is carried out along with the surgery to remove the cancer.

Once the mastectomy procedure is completed, you can opt for a breast reconstruction surgery to rebuild the area. You may opt for this procedure at the time of breast cancer removal or at a later stage. If you are considering breast reconstruction surgery then you should discuss it with your surgeon.

Surgery is sometimes not used to treat cancer, but in slowing the progression of cancer or even reducing its symptoms.It is important you talk to your surgeon before the procedure to understand the goal of the surgery.
