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

Skin cancer occurs when the DNA of the cells undergo mutations, thus causing unsystematic cell growth which evolve into a cancerous mass. This abnormality stems from the over-exposure of your skin to the Ultraviolet Radiations of the sun. 

However, there are other factors too that escalate the risks of skin cancer.

Fairer skin tone: Inadequate pigmentation or melanin content in the skin offers less protection against the harmful UV radiations. Having red or blond hair or light-colored eyes makes you more vulnerable to this condition.
Sunburns: A history of sunburns can often be the root cause behind skin cancer.
Excessive exposure to the sun: If you spend a considerable amount of time under the sun and especially if your skin is not protected by clothing or sunscreen, you tend to get a tan. A tan is the skin s response to extreme UV radiations.
Moles: Abnormally large moles, known as dysplastic nevi, are more likely to turn malignant. Watch out for any change in the texture of the moles, which is one of the most important symptoms of skin cancer.
Family history: According to studies, genes are considered to be one of the causes behind skin cancer. Hence, a family history of this condition could spell trouble for one.
Personal history: Having suffered from skin cancer previously in life could endanger one even more.
Pre-cancerous skin injury: Skin lesions, also known as actinic keratosis, make you prone to developing pre-cancerous growths on the skin. These could appear as scaly rough patches, ranging from brown to pink in color. They usually crop up on the hands, head and faces of people who are comparatively of a fairer skin tone.
A weak immune system: People having a poor immunity system, including the ones affected by HIV/AIDS or are on immunosuppressant drugs which follow any organ transplantation have greater risks of developing cancer.
Exposure to radiation: Radiation therapy is an often used treatment method for treating various skin conditions such as acne and eczema. Having been exposed to radiations, one could be indisposed to this condition even more.
Exposure to certain chemicals: Exposure to certain substances such as arsenic might increase your vulnerability manifold.

If you are suffering from breast cancer, it is recommended that you undertake Ayurvedic measures for an effective and natural treatment. Breast cancer is a form of cancer that occurs in the cells of your breasts. The breast cells undergo abnormal growth and go out of control. This form of cancer is likely to occur in both women and men, although it is most common in women. A lot of breast cancer cases start from the ducts or lobes, while others start from the cellular lining of your milk ducts.

Ayurvedic view
According to the principles of Ayurveda, your body is based on the tridoshas, which include vata, pitta, and kapha.

An imbalance in these doshas can lead to diseases and disruption in your health. Cancer occurs when an imbalance of all the three doshas is experienced.
An improper diet and lifestyle account for being the primary reason for this imbalance in doshas, leading to breast cancer.
Your digestive fire is also affected, which leads to the accumulation of toxins, thereby blocking all the channels of your body.
All these factors are collectively responsible for the development of breast cancer.
Ayurvedic treatment

Ayurvedic treatment for breast cancer is very effective because of its natural approach.

Breast Cancer - Can Ayurveda Help You Treat it?

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?

The prostate gland in males surrounds the urethra, through which urine and sperm are passed out of the body. Its function is to secrete a fluid, which provides nourishment to the sperm. It is about the shape of a walnut and is present between the pubic bone and the rectum.

As a man crosses 40, the prostate gland begins to increase in size due to an increase in the number of cells. This is known as hyperplasia.  The condition is usually benign and therefore the name benign prostate hyperplasia (BPH). As it continues to grow, there is an increased pressure on the urethra. Therefore, there can be problems with urination. The bladder, being a muscular organ, compensates to some extent and so the problems with urination are mostly managed. If left untreated, this can continue to be a major problem and the bladder may not be able to compensate. In men who are 60-plus, BPH is very common.

Signs and symptoms 

One of the initial symptoms of BPH is when the urine stream begins to grow weak.
There could also be a reduced speed of passing urine.
Men with BPH never have a feeling of complete emptying of the bladder.
On the other hand, there is also a constant difficulty in initiating a urine stream. There could be intermittent breaks in the urine stream.
The person may feel the need to strain to initiate the stream and to ensure complete emptying.
There could be dribbling of urine after passing urine.
The duration between two bathroom visits can constantly reduce, with the constant urge to urinate.
There is a constant urge to visit the bathroom, which is more common in the night. One of the most annoying features of BPH is the walking up at night to urinate, but with an inability to initiate a stream and an inability to completely empty the bladder, it leaves the person very irritated and frustrated.
There could be blood in the urine. In fact, blood in the urine accompanied by fever, chills, nausea and vomiting are indications of an emergency.
There could be blockage of urine completely, if the enlargement is quite severe.
Diagnosis
If you are having any of these symptoms, then the doctor will first test for an enlarged prostate through a digital rectal exam. Then a test is done to check a chemical called prostate specific antigen.  Increased levels of this chemical is almost always indicative of BPH. In addition, X-rays and scanning may be used to confirm diagnosis. 

Treatment
Though medications are available, confirmatory treatment is through surgical removal. The procedure needs a inimum of 2 to 3 days.

Enlarged Prostate - 10 Warning Signs To Watch Out For

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.
