Why is this cancer preventable?
Unlike most malignant tumors, cervical cancer has a known specific cause - the long-term presence of oncogenic types of human papillomavirus. The path of development is also known: from infection through mild, moderate and severe dysplasia to invasive cancer.
This journey takes years, often more than ten years. All this time, the changes are at a stage where they can be detected by a simple study and cured with a small procedure. That is why in countries with established screening, the incidence has decreased significantly.
Two measures make this cancer almost entirely preventable: HPV vaccination and regular screening. Both are affordable and do not require complex technology.
Symptoms: why they are not present at an early stage
- At the stage of dysplasia and early cancer there are no symptoms at all
- Bloody discharge after sexual intercourse is one of the first noticeable signs
- Bleeding between periods
- Any bleeding after menopause
- Copious watery or bloody discharge, sometimes with an unpleasant odor
- Pain in the lower abdomen, lower back, sacral area
- Pain during intercourse
- In a common process: swelling of the leg, pain in the leg, difficulty urinating and defecating, blood in the urine
- Weight loss, weakness, anemia
Risk factors
- Persistent infection with oncogenic HPV types is a major factor
- Lack of regular screening is the main reason for advanced cases
- Smoking significantly increases the risk
- Immunodeficiency, HIV infection
- Early onset of sexual activity, large number of partners
- Multiple births
- Long-term use of hormonal contraceptives - the contribution is small and is being discussed
- Other sexually transmitted infections
- Lack of HPV vaccination
- Low socio-economic level as a factor in the inaccessibility of screening
Screening: what and when
- Pap test or liquid cytology - evaluation of cervical cells
- Testing for high-oncogenic risk HPV is the main screening method in many protocols
- Combined cytology and HPV testing
- The age of onset and intervals are determined by the doctor in accordance with accepted recommendations
- If the results are changed - video colposcopy with targeted biopsy
- Screening is also necessary for vaccinated women, since the vaccine does not protect against all types of the virus.
- Screening is also needed in the absence of sexual activity at present, if it was previously
Separately, it is worth telling women who have had a hysterectomy: if the cervix is preserved, screening continues. If the uterus and cervix are removed for a benign reason, the issue is discussed with the doctor individually.
Diagnosis if suspected
- Speculum examination and bimanual examination
- Video colposcopy with targeted biopsy - confirmation of diagnosis
- Curettage of the cervical canal with a lesion extending into the canal
- Histological examination - determines the type of tumor
- MRI of the pelvis - assessing tumor size and spread
- CT scan of the chest, abdomen and pelvis
- PET-CT in selected clinical situations
- Cystoscopy and rectoscopy for suspected invasion into adjacent organs
- Ultrasound of the kidneys to rule out compression of the ureters
- General and biochemical blood test, assessment of kidney function
Treatment
- Conization of the cervix - with preinvasive and microinvasive forms; may preserve the possibility of pregnancy
- Trachelectomy - removal of the cervix while preserving the uterine body; organ-preserving option for young women in the early stages
- Radical hysterectomy with parametrium removal and pelvic lymphadenectomy
- Laparoscopic and open approaches depending on the stage and clinical situation
- Radiation therapy, including brachytherapy
- Chemoradiation therapy is the standard for locally advanced stages
- Chemotherapy and targeted therapy for advanced disease
- Ureteral stenting or nephrostomy for urinary tract compression
- Discussion of fertility preservation before treatment in young patients
Where to get screened in Tashkent
Screening requires cytology, HPV analysis and, if changes occur, video colposcopy with biopsy.
In Tashkent, these studies are carried out at the UROLOGIC COMPLEX medical center and at the Tashkent Medical Park clinic; Once the diagnosis is confirmed, further treatment is determined jointly with the oncology service.
If you have never had a PAP test, this is the most important point of everything written above. One study every few years virtually eliminates the possibility of encountering an advanced form of this disease. Clinic contacts are below.
