Worldwide around 450,000 – 500,000
cases of cancer cervix are diagnosed each
year. In developing countries, it is the most
common cause of cancer death, 275,000
deaths in 2008, and four fifths of these
occurred in the low and medium resource
countries. In spite of organized screening
protocols in the US still 15,000 women
are diagnosed annually out of which there
are 4,800 annual deaths.Persistent
Infection with Oncogenic HPV is THE
NECESSARY CAUSE of cervical cancer.
It has been a great disgrace for humanity as a whole and medical fraternity in particular that cervical cancer a preventable disease still remains at bay. Death due to cervical cancer can aptly be described as death due to incompetency. What has made us incompetent is the point of concern. We have all gathered here today for a great and noble cause to eradicate the darkness that surrounds this very common disease. It is the most common gynaecological cancer worldwide.
We have to understand that cancer cervix has no symptoms. It is symptomatic only in advanced stages and that will be the success to all screening programmes.
Women with early cervical cancers and pre-cancers usually have no symptoms. Symptoms often do not begin until a pre-cancer becomes a true invasive cancer and grows into nearby organs.When this happens, the most common symptoms are abnormal vaginal bleeding, such as bleeding after vaginal intercourse, bleeding after menopause, bleeding and spotting between periods, and having longer or heavier (menstrual) periods than usual. Bleeding after douching, or after a pelvic exam is a common symptom of cervical cancer .An unusual discharge from the vagina — the discharge may contain some blood and may occur between periods or after menopause.
These signs and symptoms can also be caused by conditions other than cervical cancer. For example, infections or a simple polyp in the cervix or sometimes irregular bleeding due to hormonal changes can cause pain or bleeding. Having any of these problems should warrant a urgent check-up by a professional right away – in spite of regular Pap tests. If it is an infection, or hormonal bleeding or a simple polyp, it will need to be treated. If it is cancer, ignoring symptoms may allow it to progress to a more advanced stage and lower chances for effective treatment. Persistent vaginal discharge especially blood stained or foul smelling should never be ignored. Most often it is a telltale sign of cervical cancer.
Having said that , it is always better, not to wait for symptoms to appear. Screening regularly is the key to pick this disease in a precancerous or very early stage where treatment is very rewarding and almost 100% successful.
The cervical cancer grows by extending upward to the endometrial cavity and downward to the vagina and laterally to the pelvic walls. The tumor can also extend to the bladder and rectum directly.
Hence the other common symptoms include:
Cancer cervix is preventable but yet to be prevented.
Factors that have prevented its prevention are:
Cancer cervix is a disease of great public health importance.HPV is a necessary cause for cancer cervix. HPV 16 & 18 account for 70% of all cancer cervix. Fortunately vaccine is now available for the above strains. In spite of that screening is mandatory because there are no symptoms in early stages. At this time down staging by Visual inspection is the most important tool in our armamentarium. However spreading awareness is our onus.
