About Ovarian Cancer

Overview

Ovarian cancer is a type of cancer that starts in the ovaries, which are the female reproductive organs responsible for producing eggs and hormones. It occurs when abnormal cells in the ovaries begin to multiply uncontrollably, forming a tumor. If left untreated, the tumor can spread to other parts of the body, a condition known as metastatic ovarian cancer. Ovarian cancer can be categorized into different types, with the most common being epithelial cancer, which originates in the cells that cover the ovary. There are also related types, such as fallopian tube cancer and primary peritoneal cancer, which can spread to the ovaries. These cancers have similar treatments to ovarian cancer. It's important to note that ovarian cancer often has vague symptoms in its early stages, making it challenging to diagnose. Recognizing the symptoms and seeking medical attention promptly can lead to early detection and improved outcomes.

Causes and Risk Factors

Ovarian cancer is a complex disease with various causes. The exact mechanisms are not fully understood, but genetics and hormonal imbalances as well as inflammation may play a role in its development.

Non-modifiable risk factors are risk factors that cannot be changed. Non-modifiable risk factors of ovarian cancer include:

• Postmenopausal age
• Caucasian race
• Personal history of breast or endometrial cancer
• Family history of ovarian cancer
• BRCA1 or BRCA2 gene mutations
• Lynch syndrome
• Endometriosis

Modifiable risk factors are risk factors that can be changed or influenced. Modifiable risk factors of ovarian cancer:

• Never having given birth
• Having children at a later age
• Obesity
• Undergoing certain infertility treatments

It's important to note that these risk factors can increase the likelihood of developing ovarian cancer but do not guarantee its occurrence. If you have concerns about your risk factors or symptoms, it's always best to consult with your healthcare professional for personalized advice.

Symptoms

Common early symptoms of ovarian cancer include:

• Bloating
• Pelvic or abdominal pain
• Feeling full soon after starting to eat
• Increased urgency or frequency of urination

As ovarian cancer progresses or reaches a higher severity, the following symptoms may occur:

• Fatigue
• Back pain
• Changes in menstruation, such as irregular bleeding
• Pain during sex
• Upset stomach or constipation

It's important to note that these symptoms can have various causes and may not necessarily be indicative of ovarian cancer. However, if you experience any of these symptoms and they are new, frequent, or persistent, it is advisable to seek medical advice for further evaluation. Early detection is crucial for effective treatment.

Diagnosis

To diagnose ovarian cancer, doctors commonly perform the following examinations, tests, and procedures:

• Physical exam and health history: This includes a general exam of the body and a discussion about the patient's health habits and past illnesses.
• Pelvic exam: During the exam, the healthcare provider will gently examine the area around the vagina, and then use a speculum, a tool that helps open the vagina slightly, to look at the cervix (the opening to the uterus). They may also use their hands to feel the uterus, ovaries, and other organs to check for any lumps or changes.
• Biomarker tests: This blood test measures the level of CA 125, a biomarker for ovarian cancer.

Additional examinations, tests, and procedures to determine the stage or severity of ovarian cancer may include:

• Imaging tools: Transvaginal ultrasound, CT scan, or MRI can provide clear images of the ovaries to detect tumors. Additional tests may be conducted to assess potential spread of cancer to other areas of the body.
• Surgical biopsy: Suspected cancerous tissue is removed for examination by a pathologist.
• Laparoscopy: Doctors use a thin, lighted tube to look for changes inside the ovaries.

Note that these examinations, tests, and procedures should be discussed with your healthcare provider to determine the most appropriate course of action for your individual situation.

Treatment Options

The goals of treatment for ovarian cancer are to achieve a cure or stop the cancer from progressing, as well as to reduce symptoms. Here are the different types of treatments and how they work to achieve these goals:

• Surgery: The main treatment option for ovarian cancer is surgery. The goal of surgery is to remove as much cancer as possible. The type of surgery depends on the stage of the cancer.
• Chemotherapy: Chemotherapy uses drugs to kill cancer cells. Platinum-based chemotherapy drugs, such as cisplatin or carboplatin, are commonly used in combination with other drugs. Chemotherapy can be administered intravenously or directly into the abdominal cavity. It is effective in treating epithelial ovarian cancer at any stage.
• Targeted therapy: Targeted therapy uses drugs that target specific proteins or molecules involved in the growth and spread of cancer cells. It can be used in combination with chemotherapy or on its own.
• Hormone therapy: Hormone therapy uses drugs to block the effects of certain hormones, such as estrogen, that can promote the growth of some types of ovarian cancer.

It's important to note that specific treatment recommendations depend on factors like the stage and grade of cancer. Health behavior changes, such as maintaining a healthy lifestyle and following a nutritious diet, can also support overall treatment outcomes.

Treatment decisions should be individualized based on patient characteristics and goals. Consult with a healthcare professional for appropriate medication dosing and side effect information.
