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 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

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 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?

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?

What menstrual problems are to women, prostate problems are to men. The prostate is a gland in the lower abdomen that aids in the production of semen. The prostate is walnut sized in a young man, but can get enlarged with age. As it grows bigger, it can cause a number of problems. These are commonly seen after a man celebrates his 50th birthday.

There are three common prostate problems faced by men. Some of the symptoms that can tell if a man has a prostate problem are:

1. Difficulty faced while urinating
2. The urge to urinate frequently at night
3. Constant feeling of a full bladder
4. Pain while urinating
5. Blood in the urine

Prostatitis

This can be defined as inflammation of the prostate gland. In most cases the cause of this inflammation is unknown. However, there are two types of prostatitis; bacterial and nonbacterial. While the former reacts well to antibiotics, the latter is more difficult to control. Symptoms of this disease vary from one person to the next. Some of the factors that could trigger this disease are:

1. Chemical irritants
2. Past bacterial infection
3. Dysfunctional pelvic floor muscles
4. Sexual abuse
5. Chronic anxiety

Enlarged prostate

As mentioned earlier, as men get older, the prostate gland tends to grow in size. This growth is benign, but can block the bladder neck and prostatic urethra. This can cause problems urinating and lead to acute urinary retention. This can be very painful. Inserting a catheter can provide temporary relief and help release stored urine. Chronic retention is much less common and is associated with high bladder pressure and can damage the kidneys.

Prostate cancer

Advancing age and family genetic history are said to be the main triggers of prostate cancer. This type of cancer can remain restricted to the prostate gland in its early stages but may spread to the other glands as the cancer advances. This can also cause the growth of secondary tumors in the bones.

The only way to correctly diagnose a prostate problem is with a thorough physical examination. This includes a digital rectal exam where the doctor will insert a gloved finger into your rectum to check the size of your prostate, a blood test, mid stream urine tests and ultrasounds. In some cases a biopsy of the prostate may also be required. Depending on the diagnosis, your doctor may prescribe antibiotics, surgery, radiotherapy or hormone therapy to manage your prostate.
