People sometimes call ovarian cancer a "silent disease" since its early signs might be subtle and easy to miss. But a lot of folks don't know that ovarian cancer isn't simply one disease. There are different kinds, and each one acts differently, grows at a different rate, and needs a particular kind of treatment.

Knowing what kinds of ovarian cancer there are might help patients and their families make better choices about diagnosis and treatment.

The National Cancer Institute says that ovarian cancer is grouped by the type of cells where it starts.

What is cancer of the ovaries?

The ovaries are where ovarian cancer starts. They are part of the female reproductive system. These organs make eggs and hormones like progesterone and estrogen.

Cancer happens when cells that shouldn't grow out of control do so and create a tumor. It can spread to surrounding organs and other regions of the body if it isn't treated right away.

The World Health Organization says that finding diseases early is very important for improving survival rates.

The Most Common Types of Ovarian Cancer

Ovarian cancer is mainly divided into three major types:

1. Epithelial Ovarian Cancer (Most Common)

This is the most frequent form, making up around 85–90% of all ovarian malignancies. It begins in the cells that cover the outside of the ovary.

There are other sorts, such as:

  • Serous carcinoma (the most prevalent type)
  • Carcinoma with mucin
  • Endometrioid carcinoma
  • Carcinoma of clear cells

Important parts:

  • Most of the time, it happens to elderly women.
  • Frequently identified at an advanced stage
  • Can spread quickly if not addressed

2. Tumors of Germ Cells

These tumors start in the cells that make eggs.

Important parts:

  • More prevalent in girls and women under 30
  • Often found early
  • Usually easy to treat

There are other sorts, such as:

  • Dysgerminoma
  • Yolk sac tumor
  • Teratoma

3. Stromal Tumors

These begin in the connective tissue cells that make hormones.

Main parts:

  • Not very common compared to other sorts
  • May produce hormones, which might cause early signs
  • Frequently diagnosed before epithelial malignancies

There are other sorts, such as:

  • Tumors of granulosa cells
  • Sertoli-Leydig cell cancers

Uncommon Forms of Ovarian Cancer

Some less common varieties are:

  • Carcinoma of small cells
  • Ovarian sarcoma
  • Borderline tumors (low risk of spreading)

These are uncommon but can necessitate expert intervention.

Symptoms May Differ by Type

Distinct kinds of ovarian cancer may have distinct symptoms; some frequent ones are:

  • Bloating in the stomach
  • Pain in the pelvis
  • Getting full soon
  • Going to the bathroom a lot

The NHS says that you should see a doctor if your symptoms don't go away.

What Makes Ovarian Cancer Happen?

There is not always an obvious reason; however, some things that make you more likely to get it are:

  • History of cancer in the family
  • Changes in genes (BRCA1, BRCA2)
  • Age (risk increases post-menopause)
  • Hormonal factors

How Do Doctors Find Ovarian Cancer?

Doctors might use:

  • Ultrasound
  • Tests on blood (CA-125)
  • CT scan and biopsy

Early diagnosis makes treatment more likely to work.

Why does it matter to know the type

Different types of ovarian cancer respond to treatment in different ways.

  • Chemotherapy and surgery may be needed for epithelial malignancies.
  • Germ cell cancers frequently have favorable responses to treatment.
  • Hormone therapy may be part of the treatment for stromal tumors.

Knowing the type helps doctors figure out the best way to treat it.

Is it possible to stop ovarian cancer?

There is no sure way to stop ovarian cancer, but you can lower your risk by:

  • Regular checkups for health
  • Genetic counseling if you are at risk
  • Keeping a healthy way of life
