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

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?

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.

What You Should Know About Breast Lump Detection

World Cancer Day, organized by the Union for International Cancer Control (UICC) and celebrated each year on 4 February, is an opportunity to rally the international community to end the injustice of preventable suffering from cancer.
Cancer is one of the worst diseases, which kills millions of people across the world. While there is a wide range of treatment options available, the best way to deal with it is to ensure a good diet along with a healthy lifestyle. Here is a list of cancer-fighting food products, which can immensely help to prevent cancer.

Green vegetables: Leafy green vegetables have multiple health benefits. They are not only rich in minerals, vitamins, enzymes, and antioxidants, but also have very low content of calories, toxins, and sodium. Being antiviral and antibacterial in nature, green vegetables can successfully inactivate carcinogens, halt metastasis and pause the formation of a tumour. Certain vegetables contain isothiocyanates that can detox the cells. Some of the vegetables that are mighty effective in countering cancer cells include kale, romaine, watercress, nutritious, spinach, collard greens etc.
Berries: Berries are one of the best antioxidants among all food items, owing to their high ORAC score. Their antiviral and anti-fungal nature of berries is extremely healthy for the body. Moreover, abundant supply of vitamin A and C makes berries a perfect agent for increasing body immunity. Free radicals are one of the top reasons for metastasis. The proanthocyanidin content of berries helps the body to get a hang of free radicals, thereby decreasing the chances of cancer cells to grow rapidly. They can be consumed daily with any meals.
Spices and herbs: There are a lot of herbs and spices, which boost the immune system and prevents cancer cells to grow further. Turmeric, for instance, is scientifically proved to be a great agent for reducing tumor size and effectively countering breast cancer and colon cancer. Some of the other herbs and spices include black pepper, ginger, raw garlic, parsley, oregano, and basil. They can be consumed daily in the form of juice or along with regular meals.
Organic meat: Many scientists are of the view that organic meat does wonder in a cancer diet. Liver of beef and chicken has high B12 content and helps to remove harmful toxins from the digestive tract and liver. They can balance hormone, digest fat and counter the side effects of triglycerides, drugs, and obesity. This can be included in the diet every alternate day.
Seeds and nuts: Flax seeds and chia seeds are few nutrient-power packed foods in the world. They should be included in the diet due to high fiber, mineral, and fatty acid content.

How to become less prone to cancer

There are various known reasons why cancer takes root in a healthy body. The deadly disease takes away millions of lives worldwide and remedies in food to tackle it are constantly a subject of research. However taking this one food item off your daily diet can help becoming less prone to cancer.

Senior cancer experts stress that sugar feeds cancer. According to his belief, backed by years of research and medical expertise, it is possible to starve cancer out of a person’s body. When sugar breaks down in the body in a non-oxidative manner, adenosine triphosphate (ATP) is generated which causes cancer cells and tumor to grow.

Research states that cancer is a dysfunction of the mitochondria caused by fermentation of sugar in the cells instead of orthodox respiration of normal cells. This can be tackled by limiting the supply, just by cutting down the intake of sugar every day. A small amount of sugar in a healthy and requisite proportion is acceptable but excessive sugar must be avoided in order to choke cancer out from the body.

Specifically, the intake of sugar in processed foods must be cut down. Everything that is sweet isn't sugar! Avoiding processed foods will simply eliminate the bad salts and bad sugars from your diet. Eating at fast food joints too must be cut down completely as the food they serve is frozen and needs a lot of preservatives. You can always switch to fruits if you have a sweet tooth. Diet-wise, consume more green leafy vegetables, developing a plant and natural nutrient based diet is an ideal method to tackle cancer.

Are You Aware That You Are Feeding Cancer Daily?

Cancer today is not as rare as it once was. Today, cancer affects the young and old alike. One of the reasons for this is the pollution in particular air and water pollution that we are exposed to on daily basis.
The air we breathe in today is a mixture of smoke, particulate matter and noxious gases that causes great harm to our bodies. Amongst these, particulate matter that is smaller than 2.5 millionths of a metre is the worst.

These particle matters are emitted into the air from car exhausts, industrial exhausts, coal fires, wood stoves etc. While the body s natural defences help keep larger particle matter out of the system by sneezing or coughing it out, smaller particle matter enters the body easily. These then get trapped in the lungs and enter the bloodstream. Particle matter has in particular been linked to increasing number of lung cancer cases. Apart from lung cancer, coal tar particle matter has been linked to bladder cancer, soot to oesophageal cancer and benzene and other pesticides to leukaemia.

Radon is another source of air pollution that is emitted from the ground. In some cases, radon can also be emitted through the water. As this gas decays, it releases tiny particles that when inhaled bombard the lung cells with radiation that can cause radiation. Smoking can worsen this effect and increase a person s risk of suffering from lung cancer. Both first-hand and second-hand smoking have also been linked to breast cancer. Apart from trying to reduce emissions to lower air pollution, it is also important to clean filets of air conditions, etc. regularly to lower indoor air pollution. Preventing the smoking of tobacco in public spaces can also help improve air quality.

All pollutants emitted by us eventually find their way into the water we drink. Even if you are not drinking contaminated water, merely, showering or swimming in contaminated water can make your body more vulnerable to the carcinogens in it. Common water pollutants include arsenic, hazardous waste, animal waste, radon, chemicals and asbestos. Drinking water with concentrated amounts of arsenic has been linked to cancer of the lungs, liver, kidney and bladder while the chlorine used to treat drinking water increases the risk of bladder and rectal cancer.

To reduce the risks of cancer caused by polluted water, it is essential to reduce disinfectant by products by keeping water treatment facilities updated and promote green chemistry and alternative assessments to reduce pollution as a whole.
