Cryosurgery, or as it is also called cryotherapy - is one of today's gentle treatment for the destruction of cancer (as well as benign) tumor tissue. During procedures used extremely low temperature artificially created with liquid nitrogen or argon. Frozen tissue itself and thawing process have very detrimental effect on any tumor cells.
"Cold" treatment
If the tumor is superficial, liquid nitrogen is applied directly to it. However, cryosurgery is used as a method of struggle with malignant / benign tumors of internal organs, bones. For this purpose cryo (or multiple cryo), which is under the control of ultrasound or Magnetic resonance imaging is administered directly to the affected area during open surgery or through skin. After the procedure the tumor frozen thawed (slowly), and the remnants of dead cells during the process are absorbed by the body.
This type of treatment is now used by a doctor to deal with the following types of benign, and most importantly, malignant neoplasms:
- retinoblastoma (malignant tumor of the retina that occurs in children) in cases where the tumor is only the part of the retina;
- skin cancer in the early stages, including squamous and basal cell, as well as some premalignant changes in the skin tissues, such as actinic keratosis;
- precancerous cervical diseases (such as cervical intraepithelial neoplasia - abnormal changes in epithelial cells, which has the potential to develop into cervical cancer);
- Oncology prostate gland in the early stages (when you can not surgery or radiation therapy);
- Obscure primary liver cancer or metastasis of other malignancies in the body.
- some bone tumors, and Kaposi's sarcoma (soft tissue tumor that develops in the against HIV infection or other serious violations of immunity induced by other causes) in the early stages.
Currently actively conducting research on the effectiveness of the method cryosurgery to treat other cancers, including breast cancer, colon cancer colon, kidney. In addition, we study the comprehensive application of the method. Various combinations cryosurgery with more conventional options of cancer treatment.
