Liver Cancer: Types of Tumors

Saturday, August 21st, 2010

* BENIGN:

one of the most common is the hemangioma, a sort of tangle of blood vessels, like the spots of the same name that appears on the skin. Most hepatic hemangiomas no symptoms and therefore require no treatment, only in some cases can cause bleeding and require surgical removal. Hepatic adenomas are another type of benign tumor arising in the main liver cells. Nor cause symptoms, but may produce abdominal pain or bleeding.

* EVIL:

- Hepatocellular carcinoma or hepatocellular carcinoma: This is the most common type of liver cancer in adults, in fact it is estimated that approximately 75% of liver cancers are this type. (more…)

Cancer of Vulva

Saturday, July 24th, 2010

Cancer of the vulva accounts for 4% of gynecological malignant tumors and occurs predominantly in women over 50 years.

Risk factors for cancer of the vulva are

* local chronic irritation, for example, by scratching the lesions,
* pelvic irradiation prior
* the use of caustic or abrasive (podophyllin) and
* Papilloma virus.

What are the symptoms?

The main symptom is pruritus (itching) associated with vulvar burning and dyspareunia (pain during sexual intercourse). In more advanced cases there may be ulcers (sores) with or without superimposed infection, and pain is rare. (more…)

Radiotherapy

Saturday, June 5th, 2010

radiotherapyThe radiation destroys especially rapidly dividing cells. Usually, this means that it is cancer, but radiation can also damage normal tissues, especially those in which cells normally reproduce rapidly, like the skin, hair follicles, the inner wall of intestines, ovaries, testes and bone marrow. Specify the maximum radiation source is what most protects normal cells.

The cells have enough oxygen are more susceptible to the effects of radiation. The cells near the center of a large tumor, they sometimes get so little blood and little oxygen. As the tumor gets smaller, surviving cells appear more blood supply, making them more vulnerable to the next dose of radiation. Thus, delivering radiation in repeated doses over a long period, increases the lethal effect on tumor cells and decreases the toxic effect on normal cells. The treatment plan aimed at full repair of normal cells and tissues because the cells have the ability to heal themselves after being exposed to radiation.

Treatment of Breast Cancer Radiotherapy Session Limits

Treatment of Breast Cancer Radiotherapy

A pioneering treatment to treat breast cancer, which reduces the radiation to a half hour session, is achieving good results in trials with patients, according to doctors at University College London.

The test, used after removal of the tumor in cases where the cancer is at an advanced stage, kills any remaining cancer cells with a concentrated emission of radiation.

Currently, women with breast cancer undergoing radiation therapy five sessions lasting about six weeks after surgery, that attempts to preserve most of the chest rather than a mastectomy, according to experts.

The doctors are confident that once you go to publish the results of tests later this year, could be offered a single radiation therapy (known in its acronym in English as IORT), according to experts, led by oncologist Michael Baum whose studies published today, the newspaper “The Times”. (more…)

Testing a Less Invasive Therapy

Breast Cancer

After removing a tumor, would be reduced ray sessions from five to just one. It’s a British medical research.

After removing a breast tumor, in cases where the cancer is at an advanced stage, should be carried out sessions of radiotherapy to kill any remaining cancer cells. Currently, patients undergo five sessions that last about six weeks after surgery. But doctors at University College London are testing a new treatment that could reduce treatment to a single session. (more…)

What is Radiation Therapy?

Saturday, February 20th, 2010

Radiation therapy uses particles similar to those of X-rays, but of higher energy capable of penetrating into the body.

This technique for cancer treatment acts on the tumor, destroying the malignant cells and preventing them from growing and reproducing, but also destroys normal tissues temporarily, so that radiotherapy has side effects. The advantage is that healthy cells have greater capacity for regeneration than cancer, so the body recovers from the damage once it has managed to remove the tumor and treatment is completed.

Radiation therapy can be administered either as monotherapy or as adjunct to surgery or chemotherapy. When the previously radiated area affected by the tumor, its size is reduced further by facilitating the surgeon’s intervention. In the event that received radiation after undergoing surgery, the goal is to destroy cells that have been left after excision.
