Cervical Cancer Vaccine
Cervical cancer is a malignant cancer of the cervix. Cervical cancer is cancer that starts in the cervix, the lower part of the uterus (womb) that opens at the top. The upper part, or body, of the uterus, is where a fetus grows. The cervix connects the body of the uterus to the (birth canal). The part of the cervix closest to the body of the uterus is called the endocervix.. Cancer of the cervix (also known as cervical cancer) begins in the lining of the cervix. Cervical cancers do not form suddenly. Normal cervical cells gradually develop pre-cancerous changes that turn into cancer. Cervical cancer is caused by several types of a virus called human papillomaviruses (HPV). The virus spreads through contact. Most women's bodies are able to fight HPV infection. Cervical cancer occurs when abnormal cells on the cervix grow out of control. The cervix is the lower part of the uterus that opens. Cervical cancer can often be cured when it's found early. Cervical cancer is a carcinoma, typically composed of squamous cells, and is similar in some respects to squamous cell cancers of the head and neck and anus.
All three of these diseases may be associated with human papillomavirus infection. The remaining 10% to 20% of cervical cancers are adenocarcinomas. Adenocarcinomas are becoming more common in women born in the last 20 to 30 years. Cervical adenocarcinoma develops from the mucus-producing gland cells of the endocervix. Most (80-90%) invasive cervical cancer develops in flat, scaly surface cells that line the cervix (called squamous cell carcinomas). Approximately 10-15% of cases develop in glandular surface cells (called adenocarcinomas). Symptoms of cervical cancer may include is pain during discharge that is tinged with blood and bleeding from that is not normal, or a change in your menstrual cycle. Cervical cancer is staged by the International Federation of Gynecology and Obstetrics (FIGO) staging system, which is based on clinical examination, rather than surgical findings. Cervical cancer is found only in women. Cervical cancers usually affect women of middle age or older, but it may be diagnosed in any reproductive-aged woman.
Cervical cancer that is caught early can usually be cured. Microinvasive cancer (stage IA) is usually treated by hysterectomy (removal of the whole uterus). Vaccines have been developed that can protect women from HPV infections. A vaccine that offers protection from the virus responsible for most cases of cervical cancer is the latest addition to the official childhood immunization schedule. The cervical cancer vaccine currently available in Australia is called Gardasil. This vaccine prevents infection with HPV types 16, 18, 6 and 11. HPV 16 and 18 are responsible for the majority (70% internationally; 80% in Australia) of cervical cancers. Cervical cancer strikes more than 10,000 U.S. women each year, killing more than 3,700. The vaccine appears to be virtually 100 percent effective against two of the most common cancer-causing HPV strains. A vaccine for girls and young women protects against the four types of HPV that cause most cervical cancers. Practicing safe (using condoms) also reduces your risk of HPV.
Cervical Cancer Treatment Tips
1. Surgery treats the cancer in the cervix and the area close to the tumor.
2. Radiation therapy (also called radiotherapy) uses high-energy rays to kill cancer cells.
3. Chemotherapy uses anticancer drugs to kill cancer cells.
4. Anticancer drugs for cervical cancer are usually given through a vein.
5. Electrosurgery, cryosurgery, podophyllum, and trichloroacetic acid are methods used to remove HPV in mucosal tissue.
6. A vaccine that offers protection from the virus responsible for most cases of cervical cancer
7. Practicing safe (using condoms) also reduces your risk of HPV and STD diseases
8. Avoid Cigarette smoking is associated with an increased risk of cervical cancer.
