Hearing about cervical cancer might feel somewhat unfamiliar and even intimidating. However, if we understand this cancer well, we can take preventive steps since it is largely avoidable. Starting today, this cervical cancer series will systematically cover what cervical cancer is, its causes, symptoms, prevention, and diagnostic methods. In today’s topic, we’ll dive into the basics—what cervical cancer is and the science behind its development. Understanding cervical cancer is a key step toward safeguarding your health.
What is Cervical Cancer?
Cervical cancer is a malignant tumor that develops in the “cervix,” located at the lower part of the uterus, connecting to the vagina.The cervix acts as the entrance to the uterus and is composed of epithelial cells and glandular cells. Cervical cancer develops as these cervical cells undergo abnormal changes and grow uncontrollably.
This process of abnormal transformation is closely linked to cellular damage from external factors and the cell's inability to recover.
The cervix is made up of cell layers that protect the uterus from external irritants.
Cervical cancer progresses as normal cells gradually transform into cancerous cells. The stages of cervical cancer development typically include
Cervical cancer is categorized into two main types based on the cells where it originates
Structure and Function of Cervical Cells
The cervix is made up of cell layers that protect the uterus from external irritants.
On the cervix’s surface, there are squamous epithelial cells that play a protective role, while glandular cells inside are responsible for secretion.
Healthy cervical cells regularly renew to maintain the cervix’s function. However, when certain factors cause cell damage and abnormal changes, these cells can proliferate and potentially develop into cancer.
Abnormal Cell Changes and the Development of Cervical Cancer
Cervical cancer progresses as normal cells gradually transform into cancerous cells. The stages of cervical cancer development typically include
- Normal Cells: Healthy cervical cells regenerate and maintain normal functions.
- Mild Dysplasia: Some cells become slightly abnormal due to external stimuli, and these cells may recover naturally.
- Severe Dysplasia: Cells undergo more significant changes, posing a higher risk of advancing to cancer; this stage is often considered precancerous.
- Cervical Cancer: The abnormal cells develop into a malignant tumor, posing a risk of spreading to nearby tissues.
Main Types of Cervical Cancer
Cervical cancer is categorized into two main types based on the cells where it originates
- Squamous Cell Carcinoma: The most common type, accounting for around 90% of cervical cancers, originating in the squamous cells covering the cervix's outer layer.
- Adenocarcinoma: Arising from the glandular cells inside the cervix, this type is less common but tends to progress more rapidly.
Cervical cancer is a malignant tumor caused by abnormal changes in the cells of the cervix. With few early symptoms, understanding cervical cancer and the importance of early detection plays a crucial role in health maintenance. By learning the basics of cervical cancer’s definition and progression, you take the first step toward prevention and maintaining your health through regular screenings and proactive measures.
