Cervical cancer develops in the cervix. The lowest part of the uterus that is connected to the opening of the vagina is called cervix. Cervical cancer is often caused by human papillomavirus or HPV, which is a sexually transmitted infection.
The immune system in the body blocks the virus from causing damage when HPV is detected. In rare cases, however, the virus can survive for years. This causes the cervical cells to become cancerous. Undergoing screening tests and obtaining the HPV vaccine can lower the risk of developing cervical cancer.
Early-stage of cervical cancer are usually asymptomatic and could be difficult to detect.
The followings are the signs and symptoms of cervical cancer:
If the disease has progressed and cancer has spread to the surrounding tissues or organs, the following symptoms may appear:
Consult a gynecologist if any suspicious signs arise for examinations and Pap smear test.
Cervical cancer generally starts from the DNA mutation of the normal cervical cells. The mutation of cervical cell causes uncontrolled duplication resulting in forming a mass of cells also known as a tumor. This tumor then begins to invade and destroy the healthy cell and tissues. These cells have the tendency to metastasize (spread to other parts of the body).
It is common for most people to be infected with HPV but most of them doesn’t develop cancer from virus due to an immune system self-defense. Cancerous cells are transformed from an abnormal cervix cells due to weakened immune system. HPV virus is infected through sexual contact whether it is anal, oral or through the vagina. The other factors such as an environment or the lifestyle choices of the patients also determine their possibilities of developing cervical cancer.
