Ovarian cancer can cause vaginal discharge, but so can many other factors and conditions.

Ovarian cancer is a group of diseases that originate in the ovaries or related areas of the fallopian tubes and peritoneum and cause abnormal cells in the body to grow out of control.

The ovaries are in the pelvis on either side of the uterus, and they make specific hormones and produce eggs for reproduction. The fallopian tubes are a pair of long, slim tubes on each side of the uterus that eggs pass through from the ovaries to the uterus. The peritoneum is the lining around organs in the abdomen.

Ovarian cancer often causes symptoms such as constipation, bloating, and abdominal, back, or pelvic pain. Vaginal discharge associated with ovarian cancer is most common in stromal or germ cell tumors. Ovarian cancer treatment is often more effective when a doctor diagnoses it in the early stages.

In this article, we look at whether ovarian cancer can cause vaginal discharge. We also discuss the characteristics of abnormal vaginal discharge and other symptoms of ovarian cancer.

Ovarian cancer can cause vaginal discharge. However, several other factors can also cause this symptom, so a person should not assume they have ovarian cancer if they notice vaginal discharge.

Vaginal discharge is a common symptom of certain types of ovarian cancer, especially at the start of cancer, but not all. Epithelial ovarian cancer, the most common type, rarely causes vaginal discharge or bleeding, but germ cell and stromal cancers can.

If cancer lacks oxygen, some cells may die off and infect the tumor, causing a foul-smelling vaginal discharge.

A person who experiences continuous discharge should speak to a doctor.

The vaginal discharge ovarian cancer can cause is often clear, white, or colored with blood.

Normal discharge is usually milky white or thin and clear and typically has no odor. It may also be clear or brown at different stages of a person’s menstrual cycle.

Vaginal discharge is a mucus-like fluid that the small glands in the cervix and vagina secrete. This fluid leaks from the vagina daily to remove debris and old cells, keeping the vagina and reproductive tract clean.

The amount, color, and consistency of vaginal discharge can vary from one person to another.

A person’s discharge is typically normal if it is:

  • without odor
  • thick and sticky
  • white or clear
  • wet and slippery

Vaginal discharge may be a symptom of infection if it is:

  • foul-smelling, such as with a fishy odor
  • yellow, green, or frothy
  • thick and white like cottage cheese

An infection may also be present if the vaginal discharge occurs with bleeding, pelvic pain, or blisters and sores.


Besides certain types of ovarian cancer, various factors may cause abnormal vaginal discharge.

Factors that may cause abnormal vaginal discharge during childhood include:

  • chemicals from soaps or bubble baths
  • an infection resulting from bacteria from the digestive tract
  • a foreign object, such as a toy or toilet paper, in the vagina

Factors that may cause abnormal vaginal discharge during adulthood include:

The growth of harmful bacteria may also result from a rise in acidity in the vagina, which kills protective bacteria called lactobacilli. This can occur because of vaginal infections due to:

  • difficulty maintaining adequate hygiene
  • using antibiotics
  • frequent douching
  • semen or menstrual blood
  • diabetes
  • pregnancy
  • a foreign object, such as a tampon

In rare cases, people may have fistulas or abnormal openings between the intestine and the genital tract. These can cause vaginal discharge, which may also contain stool.

Fistulas may result from:

According to the Centers for Disease Control and Prevention (CDC), common symptoms of ovarian cancer include:

People who have symptoms of ovarian cancer, abnormal discharge, or both should immediately contact a doctor.

If a person has a yeast infection or thrush and no other symptoms of infection or ovarian cancer, they do not have to contact a doctor every time they experience discharge. This type of discharge is usually thick, white, and clumpy. Yeast infections may also cause itching and burning.

If a person consults a doctor about vaginal discharge, the doctor may ask some questions regarding:

  • the smell and look of the discharge
  • if other symptoms are present, such as itching
  • whether a person has pain during sex or urination, or constant pain in the pelvis
  • whether discharge occurs during menstruation or sex
  • if the person uses any products that may irritate the vaginal area
  • whether the person is taking antibiotics
  • whether the person has diabetes

A doctor may also do a physical examination of the pelvis and other tests, such as inserting a cotton swab into the vagina or cervix to get a sample of the discharge. They will then examine the discharge and send a sample to the lab.

Ovarian cancer may cause discharge that is often white or clear or that contains blood. This symptom is common among certain types of ovarian cancer but not all. The most common type of ovarian cancer rarely has vaginal discharge or bleeding.
