Important Stages Of Cervical Cancer

cervical cancerCervical cancer is one of the most common types of cancer found in women across the world. Cervical cancer affects the cervix, which is the lower portion of the uterus. Cervical cancer is caused due the incidence of Human Papilloma Virus or HPV. HPV generally propagates through sexual contact and can be cured if detected in the earlier stages of the disease.

Different Stages Of Cervical Cancer

Carcinoma In Situ Or Stage 0

Carcinoma in situ or Stage 0 of cervical cancer is akin to the pre-invasive cancer period when the cancerous growth and malignant cells lie on the surface of the first layer of tissues. In this stage, the cells are limited to the superficial skin and affect the outer lining of the cervix.

Stage 1

In Stage 1, cervical cancer remains restricted to the region of the cervix but starts spreading to all portions of the cervical region. This stage of cervical cancer is further divided into various subcategories which depend on the size of the tumor and its growth.

Stage 1A

This is the first level of Stage 1 in which the growth of the cancerous cells is microscopic in nature. As the stage progresses to Stage 1A1, the size of the cells is less than 3 mm deep and 7 mm wide. With the onset of Stage 1A2 the size increases to 3 mm to 5 mm in depth and almost 7 mm in width.

Stage 1B

In Stage 1B of cervical cancer, the cancerous growth can be observed under a microscope. In this stage of the disease, the tumor spreads to the connective tissues and starts invading the deeper layers of the tissues. The tumor is almost 4 cm in size in Stage 1B1 and starts growing beyond 4cm in Stage 1B2

Stage 2A

In Stage 2 of cervical cancer, the cells start spreading into the adjoining tissues but still refrain from invading the muscles and tissues of the pelvic wall.

In Stage 2A, the tumor affects the upper two thirds part of the vagina but stays away from the walls of the uterus. In Stage 2A1, the size of the tumor is less than 4 cm whereas in Stage 2A2, it becomes more than 4 cm.

Stage 2B

The cancerous growth starts spreading outside the cervical region and invades into the uterus.

Stage 3

Stage 3 finds the growth spreading into the lower parts of the vagina but remains restricted to the pelvic region. In this stage the tumor starts blocking the tubes which carry urine to the bladder and results in the kidney getting affected with cancerous growth.

Stage 4

This is the most complex stage of the Cervical Cancer in which the tumor starts affecting several other organs of the body. Stage 4A, affects the areas which are closer to the cervix such as urinary bladder and rectum. Distant organs such as liver, intestinal tract or lungs can be affected in Stage 4B of Cervical Cancer.

Cervical Cancer can be cured at all stages except the last one and it is always recommended to start a combination of treatments referred, as soon as it is diagnosed.
