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

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.

Treating Lung Cancer With Ayurveda

Being diagnosed with cancer is something no one looks forward to and Gynaecological Cancer is every woman s worst nightmare. However, if diagnosed in time, it can be treated. Cancer in any part of a woman s reproductive system is termed as gynecological cancer. It is of five types:
Cervical cancer
Ovarian cancer
Vaginal cancer
Vulvar cancer and
Uterine cancer
Paying attention to your body and understanding its natural rhythm can help you recognize signs of gynecological cancer. This is because signs of gynecological cancer can be difficult to identify unless you know your body. Here are a five signs to watch out for-
Abnormal Vaginal Bleeding: Bleeding in between periods is okay once in a while but if it happens continuously over a period of 2 to 3 months, do not ignore it. Vaginal bleeding after menopause should also never be ignored. Abnormal bleeding could be triggered by a number of conditions including cancer of the lining of the uterus. Sudden changes in your menstrual blood that persist for over 2 cycles such as heavy bleeding can also be a symptom of uterine cancer. Heavy bleeding can be defined as a period that lasts for over 7 days.
Changes in the Vulva: Any change in colour of development of bumps, sores of thickened skin should be immediately shown to a gynecologist. Any form of vulvar itching or burning should also not be ignored. These conditions could be symptoms of vulvar cancer. Hence, it is important to know what your vulva looks like normally.
Bloating: Persistent bloating that lasts for over a fortnight can be a sign of ovarian cancer. This is especially true in cases of bloating accompanied by sudden weight loss or between-period bleeding.
Change in Bathroom Habits: Due to the proximity of the bladder to the reproductive organs, a tumour or swelling in the reproductive organs can trigger symptoms similar to those of a urinary tract infection. This includes pain while urinating, difficulty passing urine, diarrhea or constipation. Urinary incontinence could also a sign of gynecological cancer.
Abdominal or Back Pain: In rare cases, lower back pain could be a sign of ovarian cancer or uterine cancer. Pain in the lower abdomen or pelvic area can also be a sign of ovarian cancer.
The above could also be signs of other health disorders. The only way of knowing for sure is by consulting a doctor. Hence, understand your body and if you notice any of these symptoms consult your gynecologist at the earliest. 

Signs of Gynecological Cancer

Does Viagra add to the risks of melanoma?

Melanoma is one of the most dangerous forms of skin cancer which develops in the skin cells that produce melanin ( the pigment that gives your skin its color). This form of skin cancer is mostly caused by exposure to ultraviolet radiations or it may be congenital in nature.

The cancer is easily detected by the naked eye and in 99% cases, the disease can be efficiently treated if detected during its early stages. Women below the 40 year age benchmark have a higher risk of cancer.

Viagra is a health supplement which is consumed in the oral form to minimize all the signs and symptoms of an erectile dysfunction. Viagra is the generic name for Sildenafil, which is used by men.

What does research say?

A medical study has shown that men who frequently use erection-enhancing drugs are 84% more likely to develop melanoma within a period of 10 years. This does not mean that you are bound to get this cancer if you are frequently using an erection enhancing drugs, but it might increase your probability of getting Melanoma.

Risk Factors

Viagra when combined with some other medicine often leads to adverse effects which might lead to cancer as well. It is always desirable that you consult your doctor before taking a Viagra in general. Some of the dangerous factors are:

1 Taking Viagra with nitrate drugs such as nitroglycerin, isosorbide mononitrate, and such others.
2 If you are experiencing an unreasonably high or low blood pressure
3 If you have any kind of a liver disease
4 If you are suffering from a kidney disease that requires dialysis (blood purification process)

Precautions

While taking Viagra, you should always consult a doctor near you. Additionally, you should also follow certain precautionary measures like:

  1. You should avoid buying Viagra online, as there is a high probability that it is fake
 2. You should try going for natural alternatives to Viagra. Studies have shown that the medicines with nitric oxide can help you in having a proper and enhanced erection. Additionally, medicines containing L-arginine are also very popular as they help in generating nitric oxide.



Does Viagra add to the risks of melanoma?

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.
