cervical cervix — malignant tumor disease. Changes are subjected
Epithelium mucosa of the uterus, during progression in the process involved
Other fabrics and organs. The level of development of cervical cancer is reflected in the classification
in stages.
Stages
cervical cancer
- 0 — «Cancer in place».
- I — The tumor is limited to the neck:
IA1 — depth
Invasia is less than 3 mm;
IA2 — Depth Ot
3 to 5 mm;
IB
— Depth of more than 5 mm. - II — tumor outside the cervix, but not
It comes to the bottom third of the vagina and the pelvis walls:
II — tumor
sprouts the upper and middle third of the vagina;
IIB — tumor
Selrusts the incoming fiber. - III — Tumor germinates the bottom third
Vagina and pelvis walls. - IV — Tumor germinates neighboring organs
(bladder, rectum), distant metastases.
Cancer treatment
cervical cervix
Treatment — Combined during Operable Tumors or only radiation therapy.
The choice of the method depends on the process stage, namely: the magnitudes of the lesion of the tissues,
Presence of metastases in lymphatic nodes.
At
IA
Stages are carried out operation in combination with radiation therapy. Young women are
Matter shack amputation, women over 50 years old — extirpation (removal along with
cervical) uterus with appendages.
On the
Stage IA2
All women show the extirpation of the uterus, however, women reproductive
ages retain ovaries and fix to the rear pole of the kidney to protect from
exposure to irradiation, then conduct a course of radiation therapy.
At
Stages of IB
and IIA
Vertheim's operation is produced: not only the uterus with cervical and appendages are removed,
But the top one third of the vagina, the near-car fiber and regional
lymphatic nodes, after which the intra-pal and remote
radiation therapy.
On the
Later stages, the operation is not carried out by applying only radiation therapy. On the
IV stages possible chemotherapy
Cistplatin.
Prevention
Development of cervical cancer
Preventive measures should be attributed to the elimination of risk factors for the development of cervical cancer
uterus, preventive inspections in women's consultations, timely treatment of background
and precancerous diseases.
Factors
Risk and HPV
- early start of sexual life;
- Early pregnancy;
- venereal diseases;
- a large number of sexual partners;
- long-term reception of oral contraceptives;
- smoking.
A large role in the development of the pathology of the cervix is currently played by the virus
human papillomas (HPV) transmitted by sexual. His strains 16, 18, 36, 45
indicate the high risk of developing oncology, and the virus can not for a very long time
make yourself felt and discovered only with PCR study. Reasonable
Giving sex and barrier contraception — The best way of prevention
HPV infection.
Exposure to risk factors indicates the need to inspect the gynecologist
no less often 1 time in 6 months.
Background
Diseases and predictions
Background diseases include pathological processes in the cervix without
Malignant changes in the epithelium:
- true erosion;
- ectopia;
- leukoplakia;
- erythlace;
- ecredopion;
- Polyps Shaika.
Modern experience shows that the popular treatment of ectopia by laser
Coagulation and cryodestruction (cavity) can significantly increase risk
Development of cervical cancer in comparison with patients without treatment.
Prejudice is the epithelium dysplasia, in which maturation is disturbed and
cell differentiation, epithelium structure without the involvement of basal membrane.
Consistence is made — cone-shaped removal of changed cervical tissues and
cervical canal.
