Understanding Cervical Cancer
Cervical cancer originates in the cells of the cervix, the lower portion of the uterus. It is primarily linked to human papillomavirus (HPV), a sexually transmitted infection. Although serious, early detection and medical advances have made effective treatment possible.
Causes and Risk Factors
Cervical cancer is mainly caused by human papillomavirus (HPV), though some factors can raise the risk of developing the disease.
- Engaging with more than one sexual partner
- Premature initiation of sexual activity
- Tobacco use
- Compromised immunity
- History of cervical cancer in the family
Stages of Cervical Cancer
Cervical cancer is classified into various stages depending on how far the disease has spread. The stages are as follows:
- Stage 0: Carcinoma in situ—pre-cancerous cells confined to the cervical surface lining
- Stage I: Cancer limited to the cervix
- Stage II: Cancer has extended beyond the cervix but has not reached the pelvic wall or lower vagina.
- Stage III: Tumor extends to the pelvic wall or lower vagina
- Stage IV: Metastasis to distant organs
Treatment Choices
Cervical cancer treatment varies based on the stage and severity of the disease. The main options are:
- Surgery: The procedure to excise cancerous tissue, often including the uterus and cervix.
