What is cervical cancer? I don't hold but I know someone that does?
Answers:
The cervix is the lower part of the uterus (womb). The upper subdivision, or body, of the uterus, is where a fetus grows. The cervix connects the body of the uterus to the vagina (birth canal). The cog of the cervix closest to the body of the uterus is called the endocervix. The bit next to the vagina is the ectocervix. Most cervical cancer start where these 2 parts run into.
Cancer of the cervix (also known as cervical cancer) begin in the inside layer of the cervix. Cervical cancers do not form suddenly. Normal cervical cell gradually develop pre-cancerous change that turn into cancer. Doctors use several terms to describe these pre-cancerous change, including cervical intraepithelial neoplasia (CIN), squamous intraepithelial lesion (SIL), and dysplasia.
There are 2 main types of cervical cancer: squamous cell carcinoma and adenocarcinoma. Cervical cancers and cervical precancers are classified by how they look lower than a microscope. About 80% to 90% of cervical cancers are squamous cell carcinomas, which are composed of cell that resemble the flat, thin cell called squamous cell that cover the surface of the endocervix. Squamous cell carcinomas most often initiate where the ectocervix join the endocervix.
The remaining 10% to 20% of cervical cancers are adenocarcinomas. Adenocarcinomas are becoming more adjectives in women born surrounded by the last 20 to 30 years. Cervical adenocarcinoma develops from the mucus-producing gland cell of the endocervix. Less commonly, cervical cancers own features of both squamous cell carcinomas and adenocarcinomas. These are called adenosquamous carcinomas or mixed carcinomas.
Only some women next to pre-cancerous changes of the cervix will develop cancer. This process usually take several years but sometimes can happen within less than a year. For most women, pre-cancerous cell will remain unchanged and jump away without any treatment. But if these precancers are treated, almost adjectives true cancers can be prevented. Pre-cancerous change and specific types of treatment for precancers are discussed in the article, "Can Cervical Cancer Be Prevented?"
Precancerous changes can be separated into different category based on how the cell of the cervix look under a microscope. These category are discussed in the sector, "Can Cervical Cancer Be Prevented?"

Do We Know What Causes Cervical Cancer?
In recent years, scientists have made much progress toward kind-hearted the steps that take place surrounded by cells of the cervix when cancer develops. In enclosure, they have identified several risk factor that increase the odds that a woman might develop cervical cancer.
The nouns of normal human cell mostly depends on the information contained in the cells^A’ chromosomes. Chromosomes are ample molecules of DNA. DNA is the chemical that carries the instructions for nearly everything our cell do. We usually resemble our parents because they are the source of our DNA. However, DNA affects more than our outward appearance.
During the past few years, scientists hold made great progress in intellectual capacity how certain change in DNA can produce normal cell to become cancerous.
Some genes (packets of our DNA) contain instructions for controlling when our cells grow and divide. Certain genes that promote cell division are call oncogenes. Others that slow down cell division or cause cell to die at the right time are called tumor suppressor genes. Cancers can be cause by DNA mutations (gene defects) that turn on oncogenes or turn off tumor suppressor genes. Scientists immediately think that HPV cause the production of 2 proteins known as E6 and E7. When these are produced, they turn stale some tumor suppressor genes. This may allow uncontrolled growth of the cervical lining cell, which in some cases will front to cancer.
But HPV does not completely explain what causes cervical cancer. Most women beside HPV don’t get cervical cancer, and guaranteed other risk factors influence which women exposed to HPV are more possible to develop cervical cancer.
Smoking: Smoking produces cancer-causing chemicals that damage the DNA of cervical cell and contribute to the development of cancer.
Immune system lesser amount: Another possible cause is immune system lesser amount. Our immune system helps hang on to us free of cancer. HIV (the AIDS virus) infection makes a woman's immune system smaller quantity able to mêlée HPV and early cervical cancer.

Cancer of the cervix which is part of the feminine reproductive organs. I pray they caught it in time and that she have had regularly programmed pap smears
