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

One of the most significant glands in the male reproductive system is the prostate gland, which is responsible for carrying urine from the bladder. It is located right under the bladder and helps in production of semen which contains sperm.
Prostate cancer is a slow growing form of cancer that is rarely seen in men below the age of 50. It may occur due to both, genetic and environmental factors. Here is a list of measures that can help in preventing this ailment.
Food Intake and Weight: Apart from age, the major factor that contributes to the risk of prostate cancer includes food and weight. Doctors suggest that bringing down your intake of calcium and fat that comes from red meat and excess dairy can help in preventing the onset of this ailment. The calcium intake should not go beyond 1,500 mg per day, which is why doctors will usually ask you not to have supplements. Cooked tomatoes with olive oil as well as cruciferous vegetables including broccoli and cauliflower should be included as a vital part of one's diet, while fish should be taken regularly as it is a source of healthy or good fat like Omega-3 fatty acids. In general, you should have fewer calories which should be matched up with ample exercise so that a healthy weight and balance is maintained.
Stress and Blood Pressure: Stress and anxiety are also major reasons that contribute to the onset of this disease. One will need to see a doctor about high blood pressure, especially the kind that is triggered by stress and causes hypertension. Also, you must control your cholesterol and stay out of depression to ensure that your risk of developing prostate cancer reduces. Also, having these conditions along with prostate cancer makes the survival chances that much lower. So, you must get the right medication and treatment for these conditions as well.
Lifestyle: One will need to quit smoking, that can cause a number of ailments including prostate cancer. Also, drinking alcohol in moderation is required in order to have a healthier lifestyle and cut the chances of developing such ailments.
Screening: While your diet and other aspects may be right, there is still a great chance of developing prostate cancer, especially if anyone in your family has been afflicted with this condition in the past. Therefore, it is recommended to get an annual screening done so that you eliminate the chances of finding it out late, and can check the growth of any anomalies as soon as they take place. Getting regular checks ups done and getting diagnosed for the problem when the earliest symptoms begin to show are both crucial for prostate cancer.


Prevention Of Prostate Cancer

Without our lungs, it would be impossible to breathe. People suffering from chronic lung diseases have compromised lung functioning. This leads to shortness of breath, fatigue and weakness. In turn, this can make the person avoid anything that exerts the lungs such as exercise. While this may seem like a good idea, it is actually detrimental. Not exercising can further weaken the lungs and muscles and make this a vicious cycle. This is where physiotherapy can help with lung rehabilitation or pulmonary rehabilitation.

Physiotherapy is a branch of medicine that treats diseases and health conditions with exercise and manual therapy. Physiotherapists may also use radiation, sound waves, electric therapy, prosthesis and assistive devices. The aim here is not to cure the disease but to improve lung functioning and the patient s quality of life. Pulmonary rehabilitation can help in a number of ways.

It reduces breathlessness: As the lung muscles weaken, their ability to pump oxygen and transport it to the other parts of the body reduces. This can make a person feel breathless even with the slightest exertion. Lung rehabilitation works on strengthening the lung muscles to reduce this breathlessness.
It increases muscle strength in the arms and legs: When oxygen does not reach the limbs, they, in turn, get weaker. By strengthening the lungs, lung rehabilitation increases the muscle strength in the patient s arms and legs.
It increases stamina and endurance: Stamina is directly linked to lung functioning. By helping the patient breathe more comfortably, lung rehabilitation increases the patient s stamina and helps him or her endure more physical exercise.
It helps patients understand your condition: Physiotherapy is part exercise and part education. By helping patients get an insight into their condition, physiotherapy helps them come to terms with their limitations and motivates them to work harder towards overcoming them.
It increases self-confidence: Feeling breathless and tired all the time can make people feel frustrated. This is especially so because these things cannot be controlled without help. Physiotherapy teaches patients how to deal with these issues and thus increases their confidence in dealing with their medical issues.
It makes patients more independent: A lack of energy can make people dependent on others. Even simple tasks like getting a bottle of water from the fridge can seem like a tiring task. Physiotherapy improves lung functioning and hence makes the person feel less tired doing everyday tasks. This makes the person more independent and improves their quality of life.

A mammogram is an imaging test where an X-ray is taken to recreate the internal imagery of your breasts. This is a screening test that is widely used to find the earliest signs of cancer. There have been instances where the early signs of cancer have been found up to three years before the actual development of the same. There are a number of benefits and risks in this screening method. So let us find out more about getting a mammogram, and whether or not you should get one.

    Procedure: A special X-ray machine is used for conducting a mammogram. There is a clear plastic plate on which the specialist will place the breast while another plate will press on the breast from above. While both the plates serve to flatten the breast and hold it still, the X-ray will be taken. Some pressure will be felt and the same steps will be repeated so as to get the side view of the breasts. The same procedure will be repeated for the other breast. Meanwhile, once it is done, you will need to wait so that the technician can check for clarity, and whether or not the procedure needs to be done again. The results of this procedure cannot be relayed by the technician, and all the images will be different because all breasts are slightly different from each other.
    Preparation: You will need to remember that the process can be a slightly painful one, especially once the pressure gets applied. Many women complain of discomfort and pain. Yet, this discomfort gets over before you know it. The pressure and pain will depend on the size of your breasts and how much they will have to be pressed in order to get a picture. The skill of the technician will also come into play here. One must remember not to get this procedure done a week or so before or after the menstrual cycle, as the breasts tend to be tender around this time, and the pain will be much more.
    Radiologist: Within a few weeks after the procedure, the radiologist will usually deliver the result. This is the professional who does an accurate reading of the X-ray.
    Normal and Abnormal Readings: If your mammogram result has a normal reading, then you can resort to getting one done every once in a while. But an abnormal reading will require further X-ray and tests so as to be able to tell for sure.
    Why should I get one: If you are over 40 and have a family history of such ailments, then you will have to get a mammogram done regularly.

Should You Get a Mammogram?

The prostate is a vital organ that located between the penis and the bladder. The prostate is involved in the release of the prostate fluid that keeps the sperm properly nourished. Prostate cancer, as the term indicates, is characterized by the abnormal and uncontrolled growth of cancerous cells in the prostate. Though the incidences of prostate cancer are low in India, necessary precautions and diagnostic steps should be carried out to prevent the condition from jeopardizing our lives.

Prostate screening includes two tests known as the Digital Rectal Exam (DRE) and Prostate-Specific Antigen test (PSA). PSA combined with DRE helps to identify prostate cancer at a very early stage. If any of the tests show an abnormality, a doctor might prescribe an ultrasound such as MRI Fusion or Prostate Biopsy to confirm the diagnosis.

Immediate treatment may not be necessary
For low-risk prostate cancer, doctors often recommend active surveillance that includes periodic blood tests, rectal exam, and biopsies.
Active surveillance helps a doctor to continuously track the growth of cancer cells and the possibility of their spread to other areas of the body.
Surveillance is fit for those who are already suffering from a serious condition or for those patients who are above the age of 60.
A surgical procedure to remove prostate cancer
Surgery is considered when the cancer has metastasized to surrounding tissue and the lymph nodes. There are two kinds of surgeries that a patient can go through- a Robot-Assisted surgery and a Retropubic surgery.
Radical Prostatectomy might have risks involved. It is, therefore, wise to discuss the pros and cons of the surgery with the doctor well in advance.
Understanding the treatment options

Radiation therapy: Radiation therapy involves the use of high-powered and high-frequency energy beams to kill cancer cells. Radiation therapy is often used to shrink the size of the cancer cells. There could be two types of radiation therapy-Brachytherapy and External beam radiation. Radiation therapy too can have its side effects. Doctors prescribe several medicines during therapy.
Hormone therapy: Hormone therapy helps to stop the production of a male hormone known as testosterone. This treatment option includes medication that completely stops the production of testosterone, the medications may also block the flow of testosterone on the cancer cells, and surgery to remove the testicles. Hormone therapy is used in advanced cancer stages.
Chemotherapy: Chemotherapy is a drug that goes into the body and kills rapidly growing and metastasizing cancer cells. It is administered through IV (intravenous), or orally as pill or both. This treatment option is employed when cancer spreads to a remote body location and does not respond to hormone therapy.
Biological therapy: Biological therapy involves the usage of the body s immune system to fight cancer. A type of biological therapy known as the sipuleucel-t is used to treat patients with advanced cancer stage and recurring cancer as well.

Prostate Cancer - How Biological Therapy Will Help?

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.
