What Is Ovarian Cancer?

Ovarian cancer is a type of cancer that originates in the ovaries. The ovaries are the female reproductive organs responsible for producing eggs and female hormones. Ovarian cancer can arise from different cell types within the ovaries, including epithelial cells (the surface layer of the ovary), germ cells (egg-producing cells), and stromal cells (supporting tissue).

It is characterized by the abnormal and uncontrolled growth of cells in the ovary, which can form tumors and may spread (metastasize) to other parts of the body if left untreated. It is often diagnosed at an advanced stage due to the absence of specific symptoms in the early stages of the disease.

Types of Ovarian Cancer

• Ovarian cancer encompasses several subtypes based on the type of cells from which it originates, including epithelial (the most common), germ cell, and stromal.
• Epithelial subtypes account for the majority of cases and typically arise from the surface layer of the ovary (epithelium).

Risk Factors

Risk factors include age (risk increases with age), a family history of ovarian or breast cancer, inherited genetic mutations such as BRCA1 and BRCA2, a personal history of breast, uterine, or colorectal cancer, and certain lifestyle factors such as smoking, obesity, and hormone replacement therapy.

Symptoms

• Ovarian cancer is often referred to as the “silent killer” because symptoms may not appear until the disease has progressed to an advanced stage.
• Common symptoms may include abdominal or pelvic pain, bloating, difficulty eating or feeling full quickly, urinary urgency or frequency, changes in bowel habits, fatigue, and unexplained weight loss.
• These symptoms are nonspecific and may be attributed to other conditions, contributing to the challenge of early detection.

Diagnosis

• Diagnosis typically involves a combination of medical history, physical examination, imaging tests such as ultrasound, CT scan, or MRI, blood tests such as the CA-125 tumor marker, and biopsy of ovarian tissue for pathological analysis.
• Ovarian cancer is often diagnosed at an advanced stage due to the lack of specific symptoms and effective screening methods for early detection.

Treatment

• Treatment depends on factors such as the stage of the disease, subtype of ovarian cancer, and the patient’s overall health and preferences.
• Treatment may include surgery to remove the tumor and affected tissues, chemotherapy, targeted therapy, and/or radiation therapy.
• Clinical trials may also be available to explore new treatment approaches and improve outcomes for patients with ovarian cancer.

Prognosis

• Prognosis varies depending on the stage of the disease at diagnosis, subtype, and the effectiveness of treatment.
• Early detection and treatment are associated with better outcomes, while advanced-stage disease has a poorer prognosis.
