Many people are terrified when they hear about cervical cancer. From my point of view, the state institutions, the health organizations, the hospitals should advertise more materials through witch the women to find out useful information and statistic about the cervical cancer. They should be informed on any aspect regarding the cervical cancer: causes, signs and symptoms, diagnosis, stages, traditional treatment, alternative treatment, prevention, statistics and so on. In order to prevent and prevent the death of a woman at each 2 minutes the women should be informed about how to prevent this disease. The doctors should advise women to do the Pap smear test as regular as necessary from two main reasons: first, to diagnose the disease and second, if you do the test at least once a year the disease will be diagnosed in early stages. As soon as you diagnose the cervical cancer as much chances of fully recovery there are. It is very important to diagnose in early stages.

Carcinoma in situ (CIS) represents an early stage of the cervical cancer characterized by the absence of invasion of surrounding tissues of the cervix. Meaning, the neoplastic cells multiply in their normal habitat, as the name tells it all "in situ" is translated in English as "in its place". Because of that carcinoma in situ doesn’t usually form a tumor, usually it forms a flat wound in the cervix, or develops as the form of the cervix, but there are cases when the carcinoma in situ forms tumor.
A common form of cancer is the invasive carcinoma originated by a carcinoma in situ lesion, because of that carcinoma in situ is considered to be a precursor or incipient form of cancer, that’s the reason why, if is left untreated for a long period of time may degenerate in a malignant neoplasm. Because of the big potential of carcinoma in situ to become an invasive carcinoma, the doctors recommend the patients to remove it completely. The carcinoma in situ is treated usually as a malignant tumor.

Carcinoma in situ is considered to be stage 0 in the evolution of cervical cancer.
When we talk about cervical cancer and cancer in general we first have to talk about 3 steps towards the cancer witch are:
-Dysplasia - is the first form of abnormal cells recognizable in a biopsy. Dysplasia can be divided in low grade dysplasia or high grade dysplasia. The risk of low-grade dysplasia to transform into cancer is low.
-Carcinoma in situ – is the same thing as high-grade dysplasia in most organs that it affects. It is a high risk of transforming into cancer if is left untreated.
-Invasive carcinoma -  is considered to be cancer, is the most advanced stage in this sequence If left untreated will invade the cervix and even cause death.
The cervical cancer is in many cases caused by cervical squamous intraepithelial lesion The term carcinoma in situ is used for the cervix and cervical cancer, but the term advanced stage of squamous intraepithelial lesion is used as synonym. This lesion is detected with the Pap smear test. The best and more of the used treatment for carcinoma in situ is the removal. The removal is the best way to stop developing it into cancer.
