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


Feeling a lump on your breasts can be a terrifying moment. 'Cancer' is the first thing that comes to mind but in reality, most lumps in the breast are not caused by cancer. Apart from cancer, breast lumps can be caused by non-cancerous growths, injuries and infections. The only way to correctly diagnose the cause of a lump in the beasts is through a biopsy. Hence, this is the first step towards treating a breast lump. From here on, treatment will depend on the cause identified.

Mastitis or Breast Infection

Mastitis is a painful infection of the breast tissue often faced by women who are breastfeeding. It can be treated with heat treatment and antibiotics. Massaging the breast while taking a warm shower or applying a warm compress. This will open up the milk ducts and should be followed by nursing the baby or using a breast pump to relieve the swelling and pain.

Abscess

Antibiotics are the first line of treatment against an abscess but this is effective only if given in the initial stage of the infection. In later stages, an abscess will need to be surgically drained.

Fibroadenomas

This is a non-cancerous tumour often found in young women. It is often difficult to distinguish between a Fibroadenoma and a cancerous tumour and hence these are usually surgically removed.

Fibrocystic Changes

In some cases, the breast itself is composed of knotted, rope like tissue. This is known as having fibrocystic breasts. If a new lump presents itself on fibrocystic breasts, a mammogram and an ultrasound are performed to evaluate the lump. In most cases fibrocystic changes do not require any medication or surgery.

Breasts Cysts

Cysts can be defined as fluid filled lumps. In some cases, these cysts become apparent at the time of ovulation and disappear after the period. In other cases, it may need to be drained with a thin needle. Cysts often recur and need to be re-drained.

Fat Necrosis and Lipoma

Fat necrosis is a lump caused by an injury to the fatty tissue in the breast. Lipoma is a fatty growth within the fatty tissue. In both these cases, no treatment is required but if it causes any problems, it can be removed.

Breast Cancer

If the biopsy reveals the presence of a cancerous tumour, you must immediately consult an oncologist. Treatment options for breast cancer include chemotherapy, radiation, surgery and hormone treatment.

Treating Lumps and Pain in Breasts of Women

Radiotherapy is a kind of treatment that kills the cancer cells by using high energy beams. Specialists use radiotherapy to treat a wide range of lung cancer. For early stage lung cancer, the radiotherapy may get rid of the cancer totally. For the small cell lung cancer you may have radiotherapy only. Then again you may have it with another treatment, for example, chemotherapy or surgery.

For small cell lung cancer, radiotherapy is used with or after chemotherapy. Chemotherapy makes the tumor in the lung shrink. You may have radiotherapy to your cerebrum, which tackles any cancer cells that may have spread to the brain. This is called prophylactic cranial illumination (PCI). In case of advanced lung cancer, the treatment contracts the tumor and controls it for a while. It additionally decreases symptoms like shortness of breath.

The types of radiotherapy used for the lungs include:

Outer radiotherapy: This kind of radiotherapy comes from a machine and is administered to the body through an external source. It depends on the kind of cancer and the progression of the same. You may have three radiotherapy sittings every day for around 12 days. This sort of radiotherapy is known as CHART ceaseless hyperfractionated quickened radiotherapy. A few people with small cell lung cancer may have treatment twice a day. If you are getting radiotherapy to control the side effects of lung cancer, you may have a single treatment or day by day medications for up to 3 weeks.



Inner radiotherapy: This is called brachytherapy or endobronchial treatment. This will be administered during a bronchoscopy. The radiation is given through a thin tube that the specialist puts inside your aviation route for a few of minutes. Specialists use this sort of treatment to shrink a tumor that is blocking or pushing your breathing track and making breathing troublesome for you.

These are some of the procedures that take place while you are having lung cancer radiotherapy:

Radiotherapy machines are enormous. The machines are fixed in one position or are sometimes ready to go around your body to give treatment from various angles.
Prior to your first treatment, your radiographers will clarify what you will hear and see. The treatment room normally have docks for you to connect to music players. So you can listen to your own choice of music.
You cannot feel radiotherapy when you really have the treatment. It takes anything from one second to a few minutes. It is essential to lie similarly situated every time, so the radiographers may take a short time to get you prepared.
Once you are in the right position, the staff will allow you to sit in the space for a couple of minutes. They watch you constantly on a closed circuit TV screen. They may request that you hold your breath or take shallow breaths during the treatment.
In case you have a concern or query you can always consult an expert & get answers to your questions!

Prostate Cancer -  Signs and Symptoms

Skin cancer is a condition with abnormal and cancerous skin growth. This often develops due to the over exposure of skin to the sun rays. The three main types of skin cancer include basal cell carcinoma, squamous cell carcinoma and melanoma. Skin cancer affects those areas of skin which remains sun-exposed, including ears, neck, chest, scalp, lips, face, hands, arm and legs. It can also develop on those areas of skin that are not exposed to sunlight like beneath toenails or fingernails, on palms and on genital area.

Here are some of the factors which increase your risks of getting skin cancer:

1.Fair complexion: Low levels of the pigment melanin in skin causes fair complexion. Fair- skinned individuals who have a history of hazel or blue eyes, repeated sunburns and people who have red or blond hair are highly susceptible to developing this form of cancer. Less pigment in skin makes an individual more vulnerable to skin damage from harmful UV radiation.
 
2. Excessive sun exposure: Exposure to the sun may lead to the development of skin cancer, if you don't protect your skin by sunscreen and clothing. Tanning beds and lamps may also increase the risk of developing this type of skin cancer.
                                            
3. High-altitude places: The exposure to sunlight is more intense in areas of high altitude and near the equator. Living at higher elevation also makes you more vulnerable to radiation because the sunlight is strongest there.

4. Moles: People with abnormal moles are at a higher risk of developing skin cancer. These moles are irregular in shape and are larger than normal moles.

5. Precancerous skin lesions: Your risk of developing skin cancer increases if you have skin lesion. These are scaly and rough patches that range from brown to dark pink in color. The most commonly affected areas are head, hands and face of fair-skinned people.

6. Weak immune system: Weak immune system caused by HIV or AIDS and immunosuppressant drugs that you take after an organ transplant may increase your risk of developing skin cancer.

Know If You Are At Risk Of Skin Cancer

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.
