New treatments for eye cancer
The eye cancer is a disease that until recently required a one time treatment, which eventually ended up causing partial or total blindness in virtually all patients who took him out, because it is a procedure based on radiation that severely damages the eyeballs.
Fortunately, a few days ago unveiled a new method, regarded as “revolutionary” to avoid this side effect. Assistant Professor Faculty of Medicine, American University of Colorado, Scott Oliver, was in charge of planning this new way of treating eye cancer , which could be really beneficial for patients with this pathology.
The study was published in a journal called “Archives of Ophthalmology”, in which Oliver explains in detail the procedure, which is based on a silicone oil injected into the eye to protect it in a 55% of the harmful radiation that is used to treat the disease, in order to avoid the undesirable side effect of vision loss.
Eye cancer can be of various kinds, but the most common and dangerous is called uveal melanoma. Oliver was based on the study of the disease, which can develop in people of any age and can be lethal if it spreads to vital organs like the liver or lungs.
As the method used to combat the disease is radiation therapy, Oliver believes that silicone oil can prevent cell death and prevent eye permanent blindness .
Radiation therapy and hormonal therapy in prostate cancer
It can be given external beam radiation therapy using high-energy linear accelerators or radioactive rods implanted or 198Au 125 in the prostate. The rates of impotence and urinary incontinence are somewhat lower than those that occur with surgery. Radiation therapy is the most widely used treatment for prostate carcinoma stage C.
Hormone therapy and chemical castration get a reduced androgenic stimulation of tumor. It is used as an alternative therapy for advanced-stage disease, though probably not increase survival, it does improve the quality of life for these patients. Among the options used are estrogens, LHRH analogues and antiandrogens.
The synthetic analogs of LHRH (leuprolide, buserelin, goserelin, triptorelin) act on the anterior pituitary, inhibiting the release of gonadotropins and serum testosterone levels achieved in the range of castration at 2 weeks of starting treatment. Avoid the trauma of orchiectomy and side effects of estrogen, such as gynecomastia.
Antiandrogens (cyproterone acetate, flutamide, megestrol acetate, nilumida) are competitive inhibitors of the natural receptors of androgens in target tissues, normal or malignant. Other anti-androgen drugs include finasteride, ketoconazole and suramin.
Types of Lymphoma Treatments II
* Radiation therapy: This treatment uses radiation (X-ray high energy) to destroy cancer cells. Usually this is a local treatment, ie the treatment is focused on only a part of your body where lymphoma.
* Transplantation: Sometimes high doses of chemotherapy destroy the lymphoma and to your bone marrow, which is the factory that produces blood cells. To help your bone marrow to produce new blood cells, a number of “stem cells” (stem cells, immature cells that were transformed into red blood cells, white and platelets) are derived from the bone marrow with a special machine, before chemo.
These cells are transplanted (returned) after your body. These transplanted cells will find the way to his bone marrow and restored so that it can produce new blood cells healthy.
There are two types of transplants:
* Autologous transplant – using your own bone marrow or stem cells.
* Transplant Allogenes – uses bone marrow or stem cells from a donor (usually a brother or sister).
Breast Cancer
Being ‘breast cancer‘ creates fear that the outside can be for women, in addition merciless, this cancer often comes suddenly, without permission.
But with the increasing awareness of women to conduct routine checks on her breasts. So, more day mortality rate of this cancer can be reduced further. Especially in patients under the age of 30 years. But if it turns out this cancer was already residing in your body, given the very rapid development of stage 1 to hopeless only takes less than five years. So you must be willing to do various kinds of tests, examinations and undergo a series of super-intensive treatment. All this was done so that the development of cancer cells can be identified wild spreading rate. This is called the ‘stage’. No need to panic, because the progress of medical technology is growing day by day. So there are many possibilities for you to escape from this deadly disease.
So, wants to know more details about the stadium and a variety of medical terms that must be passed by breast cancer?
Here are his notes:
Stage 1
At this stage, cancerous lump no more than 2 cm and can not be detected from outside. A very systematic treatment will be given at this stage of cancer, the aim is that cancer cells can not spread and did not continue on the next stage. At this stage, the possibility of full recovery of patients was 70%.
Stage 2
At this stage, the possibility of patient recovery is 30 – 40% depending on the extent of the spread of cancer cells. Usually cancer lump size was more than 2 even get to the level of 5 cm and had already spread to the armpit area. Or it can also measure the cancer has reached 5 centimeters but has not spread anywhere. Usually performed surgery to remove cancer cells that have spread to all parts, and radiation after surgery performed to ensure no more cancer cells left behind. Read the rest of this entry »
