Photodynamic therapy or PDT is a relatively new and non-invasive treatment for non melanomaskin cancer. It is mostly used in cases where the cancer is superficial and has not spread too deep. PDT is used mostly to treat Actinic Keratoses on the face and scalp, Basal cell carcinomas, Bowen s disease, as well as other conditions such as head and neck, mouth, lung and gullet cancer.

How does it work?
This treatment involves the use of a drug known as photosensitize or a photosensitizing agent with a specific type of light. When the photosensitizing agents get exposed to a light of a specific wavelength, a form of oxygen is produced, which eliminates nearby cancer cells. Every photosensitizer gets activated by the special light. The wavelength of the light determines how much it can penetrate into the body.

Process of Photodynamic therapy
Skin cancer is cured by PDT in several steps. The first step involves the injection of a photosensitizer into the patient s bloodstream. The blood cells absorb the agent all over the body, but in the cancer cells, it stays for a longer duration. Within 72 hours after the injection is given, the skin is exposed to light. The photosensitizer agent present in the cancer affected cells absorbs the light. An active oxygen form gets produced, which kills the cancer cells.

Other than killing the cancer cells directly, PDT uses two other ways to destroy cancerous tumors. The blood vessels in the tumor are affected, which leads to its death. The immune system also gets charged up and activated for fighting the cancer cells.

The light used for PDT is usually in the form of a laser. LEDs are also used to treat tumors present on the surface of the skin. The primary photosensitizing agent used in PDT is called porfimer sodium or Photofrin.

PDT can be undertaken in the outpatient department in a hospital. After taking the treatment, you have to keep the cancer affected area of the skin dry and covered for 36 hours. The area should be treated with care while showering. In case of thick skin lesions, repeat treatments are required within 4 weeks.

When is PDT used for skin cancer
PDT can be undertaken instead of surgery for treating basal cell cancer, Bowen s disease and actinic keratosis. PDT is used in cases where surgeries are required. It is used to treat large skin cancers, which are not very deep and in the case when several cancers develop in an area. For many skin conditions, PDT is a better remedy than undergoing a surgery.

Advantages of PDT

    There are no long term side effects.
    The process is less invasive compared to surgery.
    A very short time is taken for this therapy to be undertaken.
    The process can be repeated several times in the same area.
    Very less scarring takes place in the affected area.
    The cost of this procedure is lesser than surgery.

Treating Skin Cancer with Photodynamic Therapy

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 indicates the growth of certain unusual cells, generally uncontrolled in nature, in any part of your body. It may also refer to a malignant tumor and it can affect any organ or any part of your body. There are many different cancers accordingly, such as lung cancer, bladder cancer, skin cancer or blood cancer. Ayurveda offers effective measures for preventing cancer. Read on to find more about the tips and get better prepared to fight this killer:

1) According to Ayurveda, having fresh foods can help you to prevent cancer. Consuming more of green leafy vegetables and fresh fruits may prove to be helpful.

2)Avoiding fat based foods or fried foods can be effective in preventing cancer. Strike off hydrogenated fats (such as cookies, peanut butter, crackers etc) or saturated animal fats from your diet.

3) Exercising on a regular basis may be very helpful. Stretching exercises, walking, breathing exercises and aerobics are considered to be useful preventive measures for cancer.

4) Meditation and yoga are also effective ways to prevent cancer. These can help you to reduce stress and remain calm.

5) Drinking green tea regularly can be very useful for killing any growth of cancerous cells in your body and thus help you to prevent cancer.

6) Cutting down on foods with higher quantities of sugar can help you to prevent cancer.

7) Include foods replete in vitamin D and vitamin C or citrus foods as these help to combat many kinds of cancer.

8) Incorporate spices like turmeric in your daily cooking regimen. The 'curcumin' present in turmeric coupled with a few other accompanying properties can help to prevent the growth of cancer cells in your body.

9) Garlic, whether consumed raw or cooked, can help you to fight the killer that cancer is.

9 Ayurvedic Tips to Prevent Cancer

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

Skin cancer has two forms, melanoma and basal cell carcinoma. While the latter could be easily treated and cured, the former is hard to get rid of. Like all other forms of cancer, skin cancer can be easily treated if detected in its early stages. Ayurvedic medicines are known to cure and manage cancer for ages.

Here is a list of 10 Ayurvedic medicines that can help in fighting skin cancer.

    Aloe vera: It has numerous skin benefits. For starters, it is considered to be a natural sun skin protector. It protects the skin from the harmful ultraviolet (UV) rays of the sun. It stops the production of carcinogen and helps the body to heal faster from cancer.
    Flaxseeds: Apart from being rich in dietary fibre, this seed contains fatty acid micronutrients and lignans. The latter has the ability to stop the cancerous cells from spreading to other parts of the body.
    Astralagus: Astralagus has multiple health benefits. It not only helps to boost the immune system, but helps the body produce skin cancer agents.
    Turmeric: This is one of the oldest Ayurvedic herbs that combat a lot of diseases. Turmeric has a crucial component known as the curcumin. It is an extremely powerful antioxidant that has the capability to stop the growth of cancerous cells.
    Bilberry: Due to the availability of free radicals, bilberry tea can counter skin cancer and helps minimise the damage caused by the cancer cells. They are a strong antioxidant and help the body to recover quickly.
    Hawthorn: Hawthorn berries are strong antioxidants that not only stop the growth of cancer cells, but prevent them from affecting other organs of the body. This fruit should only be consumed if the patient is taking betablockers.
    Artemisia: Commonly known as sweet wormwood, artemisia has a compound known as the artemisinin. Studies have shown that artemisinin can stop the cancer from spreading. Being non-toxic in nature, they have no side effects at all.
    Scutellaria: More commonly known as the Chinese herb, this Ayurvedic herb stops the progression of skin cancer into further stages. They contain a compound known as the flavonoids, which are known to be an anticancer agent.
    Saffron: Saffron has the unique property of slowing down skin cancer growth. Saffron can be applied in the form of extracts in small quantities to get best results.

10 Ways to Prevent Skin Cancer with Ayurveda Treatment

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.
