About Cervical Cancer Stage 1

Overview

Stage I cervical cancer refers to cancer that is limited to the cervix and has not spread to nearby tissues or organs. It is the earliest stage of cervical cancer. Stage I is further divided into two sub-stages: IA and IB.

• Stage IA: The cancer is in its early stage and can only be seen with a microscope. It has not spread beyond the cervix. Stage IA is further divided into two subdivisions:
  • Stage IA1: The cancer is less than 3 millimeters deep into the cervix.
  • Stage IA2: The cancer is between 3 and 5 millimeters deep into the cervix.
• Stage IB: The cancer is still confined to the cervix but has invaded further than 5 millimeters deep. Stage IB is also divided into three subdivisions:
  • Stage IB1: The tumor measures 2 centimeters or smaller.
  • Stage IB2: The tumor measures between 2 and 4 centimeters.
  • Stage IB3: The tumor measures more than 4 centimeters.

Knowing the stage of cervical cancer helps in planning the most appropriate treatment for the individual.

Causes and Risk Factors

The cause of cervical cancer is primarily related to persistent Human Papillomavirus (HPV) infection. HPV, specifically types 16 and 18, is the main cause of cervical cancer. However, it's important to note that not all women with HPV infection develop cervical cancer.

Non-modifiable risk factors for cervical cancer include:

• Age: Women between the ages of 30 and 50 are at higher risk.
• Family history: Having a first-degree relative with cervical cancer increases the risk.
• Genetic factors: Certain genetic variations may increase susceptibility to HPV infection and cervical cancer.
• Maternal exposure to diethylstilbestrol (DES): Females born to mothers who took DES during pregnancy are at higher risk of cervical cancer.

Modifiable risk factors for cervical cancer include:

• HPV infection: HPV infection is the most significant risk factor for developing cervical cancer. People more likely to become infected with HPV include those who became sexually active before age 18, have multiple sexual partners, and engage in unprotected sex. The risk of HPV infection can be reduced through vaccination and safe sexual practices.
• Smoking, including second-hand smoke: Increases the risk and progression of cervical cancer.
• Weak immune system: Conditions like HIV/AIDS and immunosuppressive therapy increase susceptibility to HPV infection and cervical cancer.
• Long-term use of oral contraceptives: Using oral contraceptives for an extended period may slightly increase the risk.

Note that these are general risk factors for cervical cancer, not specifically Stage I cervical cancer. It's important to note that these risk factors can vary among individuals, and it's always best to consult with a healthcare professional for personalized advice.

Symptoms

The early stage of cervical cancer, Stage I, usually does not present any noticeable symptoms.

When symptoms do occur, they may include:

• Abnormal vaginal bleeding, such as bleeding after sex or between periods
• Vaginal bleeding after menopause
• Unusual vaginal discharge that may have a strong odor or contain blood
• Pain during sex

Symptoms of later stages of cervical cancer, when it has spread beyond the cervix, may include:

• Difficulty urinating
• Blood in the urine
• Swelling in the legs
• Difficulty having bowel movements
• Bleeding from the rectum during a bowel movement
• Persistent, dull backache
• Abdominal pain
• Fatigue

It's important to note that these symptoms can also be caused by other conditions. If you experience any of these symptoms, it is essential to consult with a doctor for a proper evaluation and diagnosis. Early detection and treatment of cervical cancer can significantly improve outcomes.

Diagnosis

Cervical cancer is first diagnosed, then staged.

To diagnose and determine the stage of cervical cancer, several examinations, tests, and procedures are commonly performed:

• Pap Test: This test collects cells from the surface of the cervix and vagina to check for abnormalities and HPV infection. This is considered a screening test. If abnormalities are identified, further evaluation is performed.
• Colposcopy: It involves using a special magnifying device called a colposcope to closely examine the cervix for any abnormal areas.
• Biopsy: A small tissue sample is taken from the cervix during a colposcopy or through a transvaginal needle biopsy guided by ultrasound. The sample is then examined under a microscope to confirm the presence of cancer cells. The tissue sample is sent to lab, where a pathologist will examine it under a microscope.

If cancer cells are found from the cervical biopsy, additional examinations, tests, and procedures are performed to determine the stage.

• Imaging tests: Imaging tests are done to provide detailed views of the inside of the body. Imaging tests help determine the location, size, and depth of the cervical cancer and spread of cancer to other parts of the body. Imaging tests include:
  • Positron emission tomography (PET) scan
  • Computed tomography (CT) scan
  • Magnetic resonance imaging (MRI) scan
  • Ultrasound
  • X-rays
• Blood tests: Blood tests may be done to check for signs that cervical cancer has spread to the bladder, kidneys, or liver.
• Examinations of near-by organs may be performed to check for spread of cervical cancer:
  • Cystoscopy: This procedure involves looking inside the bladder
  • Sigmoidoscopy: This procedure involves looking inside the rectum and lower part of the colon. Alternatively, a proctoscopy may be performed to look inside just the rectum.

For stage I cervical cancer, the mass of cancer cells will be small and cancer will not be found outside of the cervix.

Remember, these are general descriptions, and specific examinations, tests and procedures may vary based on individual circumstances. It's important to consult with your healthcare professional for personalized advice and guidance.

Treatment Options

The goals of treatment for stage I cervical cancer are to remove or destroy the cancer cells and prevent the cancer from spreading. The treatment plan may include:

Surgery:

• Conization: Removal of a cone-shaped piece of abnormal tissue from the cervix.
• Total hysterectomy: Removal of the uterus.
• Modified radical hysterectomy with lymphadenectomy: Removal of the uterus, cervix, upper part of the vagina, nearby tissues, ligaments, and lymph nodes.
• Radical trachelectomy: Removal of the cervix, nearby tissue, and upper part of the vagina.

Radiation therapy:

• External radiation therapy: High-energy beams target and destroy cancer cells.
• Internal radiation therapy: Radioactive materials are placed near the cervix to kill cancer cells.

Health behavior changes:

• Quitting smoking: Smoking can decrease the effectiveness of treatment.
• Eating a balanced diet: Providing essential nutrients for healing and recovery.

Treatment may vary based upon whether a person has stage IA or IB cervical cancer, the risk of cancer recurring, and personal factors such desire for future pregnancy. It's important to consult with a healthcare professional specialist to determine the most appropriate treatment plan for individual circumstances.
