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.
If you wish to discuss about any specific problem, you can consult a dermatologist.
- The cost of this procedure is lesser than surgery.

Ovarian cancer is a broad term used to describe cluster of different types of cancers occurring in a single organ i.e. ovary. It can occur at any age- from infancy till old age , even though ovarian carcinoma in younger/childhood comprises only 20% of all ovarian cancers. Majority of ovarian cancers are epithelial - arising from the covering from ovary or from the fallopian tube or the lining of the peritoneum of the abdominal cavity.
The Silent Killer:
Ovarian cancer is called a silent killer as majority of patients report any symptoms when the disease is in the advance stage. Hardly 2-3% of all ovarian cancers cause bleeding or hirsutism, thereby seeking prompt treatment. Majority of ovarian cancer occurs in peri/postmenopausal women which reflect change in interior milieu in terms of hormones.
Since the symptoms are non-specific, women tend to ignore them due to growing age/menopause. Also, mostly women normally don't consult physicians for such non-gynecological complaints, thereby further delaying the diagnosis. It is recommended that women remain involved in their overall health and keep themselves updated to report any abnormality immediately to a specialist.
The main symptoms associated with Ovarian Cancer are:
Bloating sensation especially after heavy meals.
Increasing abdominal girth (especially if no change in diet or if regularly exercising).
Increasing heaviness (fullness) in lower abdomen.
Persistent Gastritis, if previously absent.
Inability to eat proper meal.
Increased frequency of urination.
Further, if there is family history of breast/uterine/ovarian cancer in first and second degree relatives, this increases the risk of developing ovarian and breast cancer. Such females should remain vigilant for above-mentioned symptoms and should report promptly.

1) vitamin c rich foods
Citrus fruits, guava, amla, tomato, green leafy vegetables all of them are high in vitamin c. This element prevents the formation of cancer-causing nitrogen compounds.
Berries top the charts when it comes to cancer fighting foods. Pterostilbene, an antioxidant found in berries is a storehouse of cancer fighting properties
3) sweet potatoes
Sweet potato is full of beta carotene. Studies have revealed that consumption of high beta carotene foods like yellow, red, green colored fruits and veggies reduce the risk of various cancers.
Omega 3 fatty acids prevents the growth of cancer by preventing the growth of cancer cells and interrupting the growth of cancerous tumor. Omega-3 fatty acids also help reduce inflammation. Along with fatty fish, one can also include a tbsp of flaxseed in your daily diet.
Curcumin, the active ingredient in turmeric, acts as both an anti-inflammatory and an antioxidant, and prevents cancer by interfering with aspects of cellular signaling
5) green tea
Tea contains catechins compounds, these compounds restrict the growth of cancer.
6) cruciferous vegetables
Cruciferous vegetables like cauliflower, broccoli cabbage contain phytonutrients which may help inhibit the metabolism of carcinogens and stimulate the body's production of detoxification enzymes.
It contains lycopene which helps prevent prostate and other types of cancer.
Pomegranates are rich in ellagic acid. It slows down cancer cell growth and deactivate cancer-causing compounds.
Again, a food rich in anti-cancer substances including allicin.
