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.

While cancer has become a common place disease, most of its causes remain unknown. Most of us are not aware that few regular everyday materials present in most households are potential causes of cancer. Lets know about them, the health hazards they can cause, and be aware.
Check this list.

1. Shower curtains - shower curtains are made of toxic chemicals which get into not only the shower or the bath but also into the environment. It emits harmful chemicals which are called voc (volatile organic chemicals) and can prove to be very harmful for us.

2. Deodorants - deodorants and antiperspirants are known to have various ingredients which have cancerous properties. These sprays stay on our bodies for hours, until we wash them off. While on our bodies, they chemicals harm our skin and even through it.

3. Strong shampoos - many shampoos contain toxic chemicals though there is no scientific proof that they cause cancer. However, the array of chemicals used to make shampoos is definitely harmful for us and best, if avoided.

4. Room fresheners - air-fresheners, like deodorants have vcos which are toxic and extremely harmful for us. They aggravate asthma and even affect reproductive development. They have hazardous components which can be cancerous. It is advisable to use essential oils.

5. Scented candles - scented candles mostly have wicks made of lead. While they serve a good purpose, there is no point in using something which gives momentary relief but can prove hazardous in the long run.

6. Certain paints - permanent markers, acrylic paints, solvents, etc contain hazardous chemicals which have been associated with occurrences of cancer, allergies and oral damages.

7. Gardening chemicals - household pesticides, herbicides or fungicides that we often use in gardens can contain carcinogenic materials which are believed to cause lymphomas and breast cancer (in animal models).

8. Plastic food/beverage containers - plastic materials containing bpa, or bisphenol a are believed to dangerous for health. So when one is using plastic bottle or food container make sure it is bpa free.

9. Nonstick cookware - cooking utensils which are made with a nonstick coating (teflon) is suspected to be a carcinogen. The main chemical in nonstick coatings is perfluorooctanoic acid (pfoa) is known to cause cancer. Glass, cast iron, copper, and ceramic or pfoa free nonstick cookwares are safe.

9 Things You Must Watch To Make Your Home Cancer Free

Brain metastases from systemic cancer are the most common type of intracranial neoplasm in adults, being almost 10 times more common than primary malignant brain tumors, which cause a significant burden on the management of patients with advanced cancer (1). The lungs represent one of the most frequent sources of metastases to the brain, with a probability of (36 64%) (3). Symptoms suffered by the patients include headaches, epilepsy, focal weakness, numbness or changes in mental status. The prognosis of patients with brain metastases is not optimistic and the median survival time is  1 2 months if left untreated. The 1-year survival rate has been recorded as 10.4% (4,5). The treatment of metastatic brain tumors is complex; not only due to being able to provide local control and improve neurological function, but also due to factors such as age, performance and systemic disease status and the size, volume, location and number of metastases at presentation

CyberKnife is a robotic radiosurgery system with a linear particle accelerator (linac), which is coupled with real-time imaging to track and compensate for the patient s or target s motion. As a relatively non-invasive treatment modality, CyberKnife demonstrates certain benefits, including a more accurate target localization and improved dose delivery for the management of metastatic brain tumors that allows higher biologically effective dose delivery without increased incidence of toxicity.

In the present case, the results for the treatment of multiple brain metastases after CyberKnife surgery with a 7 8 Gy marginal dose was promising. CyberKnife for metastatic brain tumors is an effective and safe method for reducing the marginal dose prescribed for multiple brain metastases and for minimizing the radiation-related neurotoxicities. In conclusion, CyberKnife, a focused, highly-targeted radiosurgery and fractionated radiotherapy is particularly useful for multiple brain metastases. CyberKnife provides the advantage of the management of local recurrence and a tolerable complication rate. Although the treatment of brain metastases has been performed with CyberKnife, the clinical significance and optimal dose fractionation scheme require further investigation.

CyberKnife Therapy Of 24 Multiple Brain Metastases From Lung Cancer!

The condition of enlarged prostate occurs due to the enlargement of a man s prostate gland, with the passage in time. Also known as benign prostatic hyperplasia (BPH), it is more common in men over the age of 60. Some cases might have symptoms and others may be symptomless. Although the causes are relatively unknown, it is evident that BPH is not a form of cancer, neither does it cause cancer. The prostate is located below the bladder and is responsible for producing the fluid needed by semen. The growth of the prostate tissue that is associated with benign prostatic hyperplasia begins near the inner prostate which is a tissue ring around the urethra. Its growth is generally inward.

Causes
It is of common knowledge that in males, the urine originates from the bladder and flows through the urethra. BPH is a condition where the prostate experiences a benign i.e. non cancerous enlargement which leads to blockage of urine flow through the urethra (the urinary duct). The resultant enlargement, caused due to the gradual multiplication of cells, subjects the urethra to extra pressure. Further narrowing of the urethra causes more contraction of the bladder, resulting in the urine being forcefully pushed out of the body.

With time, the condition leads to the bladder muscles gradually becoming thicker, stronger and oversensitive. Contraction occurs even due to the presence of small amounts of urine, giving rise to frequent needs of urination. At one point, the bladder muscle is unable to overcome the effects of the narrowed urethra. Due to this, urine does not pass properly and the urethra is not emptied.

Some of the common symptoms of enlarged prostate include:
1. Frequent urination
2. Urgency to urinate
3. Difficulty during urination
4. A slow or weak urinary stream
5. Requirement of extra effort to urinate
6. Interrupted sleep due to need of urination

Further risks
Sometimes, when the bladder is not emptied completely, a risk of urinary tract infections develops. Some other serious problems which can be a result of enlarged prostate include blood in urine, bladder stones as well as acute urinary retention (inability to urinate). In some rare cases, kidney and/or bladder damage might also result from such a condition.

Frequent Urination - Can it be a Sign Enlarged Prostate

Causes and symptoms of enlarged prostate

The problem of an enlarged prostate or benign prostate hyperplasia is a very common occurrence as you grow older. It's known to strike men above the age of 50, with more than 50% of men after the age of 60, having this complaint.

Causes of enlarged prostate

A non-cancerous condition, enlarged prostate makes the passing of urine from the bladder through the urethra difficult. The multiplication of the prostate cells causes an enlargement of the gland, leading to a buildup of pressure on the urethra, affecting the discharge of urine from the body. The narrowing of the urethra, due to this benign condition, forces the bladder to contract more vigorously so as to push urine out of the body.

As time passes, the muscles of the bladder get significantly affected, causing them to become extremely sensitive, thicker and stronger. As a consequence, the bladder begins to contract, even if the amount of urine in the organ is negligible, causing episodes of frequent urination. Gradually, the bladder fails to completely empty itself of urine due to the constriction of the urethra. This can give rise to a number of health problems including the formation of bladder stones, urinary tract infections, blood in the urine and so on.

How can you identify the signs of the condition?

Signs of enlarged prostate are very easy to identify and include:

- A slow or weak urine flow
- Difficulty in initiating urination
- Instances of frequent urination
- A feeling of not completely emptying one's bladder
- Frequent urination during the night
- Exerting a lot to urinate
- Instances of dribbling
- Urgency to pass urine
- A feeling of urinating again minutes after doing so
- Urination that starts and stops



What Leads to an Enlarged Prostate?

International Childhood Cancer Day is celebrated annually on 15 February to raise awareness and to express support for children and adolescents with cancer, survivors and their families.

Why is Cancer the biggest Threat to the YOUNG in India?

There are fewer Indians who have successfully battled Cancer and have emerged successful. Yuvraj Singh, the legendary cricketer, who was diagnosed with a rare cancer at 29, survived due to an early detection. Cancer cases in India are not as many as they are in the developed world. However, due to late detection the survival rate in the country is far worse. Particularly, we are losing our youth to Cancer. Most tobacco (pan masala) related cancers and child cancers go undetected until very late.

Few cancers like cervical cancer and breast cancer which affect women of any age, are curable, however, due to lack of awareness and timely screening, many Indian women succumb to these cancers. The most common sites for cancer among men are lung, prostate, colon, rectum, stomach and liver while that among women are breast, colon, rectum, lung, cervix and stomach.

In proportion to our population, we lack the right infrastructure nationwide. esp in the northern and north eastern region, there is a dearth of good cancer facilities, where radiation, care or treatment can be given. Not even one third of cancer patients are alive beyond 5 years after their diagnosis in India, and about 71% of cancer deaths occur in patients in their prime productive years   between the ages of 30 to 69 years.

 Most Indians believe that cancer is generally incurable and that it should be kept secret from neighbors and family.  -  Dr Paul Goss, MD, Harvard University.

All these factors have contributed to a very high mortality rate. No wonder Cancer is dreaded in the country. Investment, infrastructure, lifestyles as well as mindsets need to change if we were to contain the Cancer mortality rate. While you need to watch out for early signs of cancer, here are the lifestyle changes every individual esp. all youth must adopt to avoid cancer.

Avoid Tobacco - both smoking and chewing.

Reduce alcohol intake - Save your organs from deteriorating.

Limit UV ray exposure from the sun - Keeps your skin safe.

Maintain a healthy diet - Include foods rich in Vitamins, minerals and fiber which nourish your body and build immunity.

Increase your level of fitness - Maintain a good bodyweight. Additional flab invites a host of troubles, that includes variety of cancers.

Seeking regular medical checkup or screening - This is the only way to prevent and get detected early on.
