In photodynamic antimicrobial chemotherapy (PACT), a combination of a photoresponsive agent and visible light causes selective destruction of microbial cells such as bacteria, fungi and viruses (Dougherty et al., 1998; Kalka et al., 2000; Konan et al., 2002). A number of studies have shown PACT to be highly effective in the in vitro destruction of viruses and protozoa, as well as Gram-positive and Gram-negative bacteria and fungi. The ability of visible light-photosensitising agent combinations to kill microorganisms has been known for over 100 years. PACT is an abbreviation and scientific term that stands for Photodynamic Antimicrobial Therapy. Photodynamic Antimicrobial Therapy (PACT) has been used effectively in medicine since the 1990s for the treatment of tumours, skin diseases and wound infections. The fungal cells, unlike human cells possess a cell wall. This cell wall is stained with a special photosensitizing gel-dye that is harmless to human cells but selectively makes fungi sensitive to a specific wavelength of light and means the bacteria and nail fungus is destroyed. PACT is used as an effective …show more content…
First, a light-sensitive drug is given. For skin cancers, it may be a cream. For internal cancers, it may be an injection into a vein, or rarely a drink. You then wait a few hours to a few days before the next step. This allows time for the drug to concentrate in the cancer cells. Next, a special light (usually a laser) is shone onto the cancer. The light activates the drug to treat the tumour. If the cancer is internal, an ultrasound or scan may be used to guide the light source to the tumour. The side effects can vary depending on where treatment is given, what drugs are used, and how you react. You may become sensitive to light for a time, and will need to take care in the sun, or other bright
After the surgery and resting time my mom had, she then had gotten the news she could now do radiation. Radiation is the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization. Basically, doctors go in and insert tubes into your body, and make sure the cancer is fully gone.
Several tests can be run once symptoms are noticed to earmark the disease with a proper diagnosis. Some of the tests include; a biopsy of the tumor, X-rays, a CT scan, a skeletal survey, bone scans or bone marrow aspiration (fluid sample) and biopsy (tissue sample). Once diagnosed, the treatments begin to hinder any advancement the cancer would or could make. Possibly removing the cancer completely through surgery is a possibility, while others include chemotherapy, radiation treatment, and bone marrow transplantation. Many times these treatments can be used concurrently with one another.
There are many different type of cancers, there are also many different types of treatments. One of the most known types of treatments would be chemotherapy. Chemotherapy can be used for a wide range of different types of cancers and diseases, and each of the different types of cancers or diseases require a different group, and sometimes order, of chemicals to properly treat the cancer or disease. These chemicals include: Alkylating agents, Antimetabolites, Anthracyclines, Topoisomerase inhibitors, mitotic inhibitors, corticosteroids, and more. Each of these drugs previously listed have its own cancer type(s) or disease(s) that it can assist in treating. Some of these cancers include: Leukemia, Lymphoma, Hodgkin disease, multiple

There are ways to treat skin cancer, in fact a lot of ways. There are about 7 ways. It all depends on where the skin cancer is at, like on your face, neck, scalp, nose, and even lips. There is different ways to treat it, it depends on where you have it at. If you leave this untreated it can they will eventually penetrate the underlying tissues and can become disfiguring. There are a lot of different surgeries you can do for this. First one is Mohs Micrographic Surgery. What that does is they use a scalpel and they remove the visible tumor. While the patient waits the layer they took of is sectioned, frozen, stained and mapped in detail, then checked under a microscope. If the cancer is still present then they do the same thing again. Next, is the
- Biological therapy: this treatment uses you immune system to fight the cancer - Chemotherapy: this is drugs that kill the cancer cells that grow abnormally quick. - Corticosteroids: this treatment is used to regulate your immune system in order to control any inflammation to your body. - Stem cell transplantation: this is a procedure to replace the bone marrow containing the disease with healthy bone marrow. - Radiation therapy: this treatment damages the cancer cells by using beams on energy that stop the cancer cells growth. Diagnosis Diagnostic test can be performed on specimens of blood, urine, bone and bone marrow to establish if there is confirmation of major or minor criteria.
Leukemia most common treatments are: Chemotherapy, Radiation therapy, and Bone marrow transplantation, and then there is also Biological therapy. In chemotherapy, patients take one or more anticancer drugs by mouth or, intravenously through IV therapy. In some cases, doctors need to inject the drugs directly into the fluid that surrounds the brain and spinal cord. Chemo can cause side effects, like losing your hair, nausea, fatigue, or easy bruising, depending on the drug. The side effects usually go away progressively between treatments or after treatments stop.

Cancer is a disease in which cells multiply out of control and gradually build a mass of tissue called a tumor. There has been a large amount of research dedicated to the treatment and cure of cancer. Several types of treatments have been developed. The following are just some of the major examples of cancer therapy: surgery, chemotherapy, radiation therapy, biologic therapy, biorhythms, unconventional treatments, and hyperthermia. Each type of treatment is discussed in detail below.
Chemotherapy, Radiation therapy, stem cell transplant, and targeted drug therapy are all forms of treatment for ALL. Chemotherapy is typically used as induction therapy for kids and adults. Chemotherapy can also be used in consolidation and maintenance therapies. Chemotherapy is given in a variety of ways. It can be given orally as a pill or liquid. It can be given intravenously by infusion into a vein. A cream on the skin can be given. Chemotherapy can also be given by direct placement either via lumbar puncture or a device placed just under the scalp. Radiation therapy uses high-powered beams, such as x-rays, to kill the cancer cells. Radiation therapy is usually recommended when the cancer has spread to the central nervous
Radiation is another type of treatment. Radiation therapy uses a special machine to deliver high energy rays that damage cancer cells and stop then from growing. These rays may be detected in the entire body, or they may be focused on certain area where leukemia cells are collecting.( Disease facts and statistics, 30)
This is a local drug delivery technique that eliminates the side effects of systemic chemotherapy. Another great example of advancement is the treatment for certain forms of skin cancer. Generally, patients with non-melanoma cancers confined to the top layer of skin, could be prescribed topical chemotherapy. Topical chemotherapy is a cream or lotion applied directly to the skin cancer. The cream uses anti-cancer drugs to destroy cancer cells. Overall, for properly selected skin cancers, the cure rate can be 80-90%. Finally, targeted therapy is currently the focus of much anticancer drug development. Targeted therapy drugs don’t work the same way as standard chemo drugs. Per the American Cancer Society, many targeted drugs go after the cancer cells’ inner workings – the programming that makes them different from normal, healthy cells, while leaving most healthy cells alone. These drugs tend to have different side effects from standard chemo
Light treatment has been utilized to treat skin inflammation. UVA and UVB have been utilized with some accomplishment to treat adamant instances of atopic skin inflammation. The medication Psoralen has been utilized as a part of blend with UVA (PUVA), however an expanded danger of skin malignancy has been
In 2007, it is predicted that almost 1.5 million people will be diagnosed with cancer in the United States (Pickle et al., 2007). More than half of these cancer patients will undergo the use of radiation as a means for treating cancer at some point during the course of their disease (Perez and Brady, 1998). Cancer, a disease caused by an uncontrollable growth of abnormal cells, affects millions of people around the world. Radiotherapy is one of the well known various methods used to treat cancer, where high powered rays are aimed directly at the tumor from the outside of the body as external radiation or an instrument is surgically placed inside the body producing a result of internal radiation. Radiation is delivered to the cancerous regions of the body to damage and destroy the cells in that area, terminating the rapid growth and division of the cells. Radiation therapy has been used by medicine as a treatment for cancer from the beginning of the twentieth century, with its earliest beginnings coming from the discovery of x-rays in 1895 by Wilhelm Röntgen. With the advancements in physics and computer programming, radiation had greatly evolved towards the end of the twentieth century and made the radiation treatment more effective. Radiation therapy is a curative treatment approach for cancer because it is successful in killing cancerous tumor cells and stop them from regenerating.
