Ovarian cancer

Some women get a sickness called cancer.

It can grow in a small part of the body. This sickness can start in the ovaries. It can also start in parts of the belly. Tiny parts of the body called cells can grow too fast. These growing parts make a lump called a tumor.

The lump might make the belly feel full or swollen. It can also cause belly pain. This sickness is more common as women get older. Doctors can use tools to help fix it. We want everyone to stay healthy.

Ovarian cancer is a sickness that grows in the ovaries.

The ovaries are small parts inside a woman's body. They are made of three types of cells. Sometimes these cells grow in a strange way. They divide too much and make a lump called a tumor.

Most cases come from a type called epithelial carcinoma. This makes up more than 95% of all cases.

This sickness can be hard to find at first. It may not cause any pain right away. Some women feel bloated or have a full belly. They might also feel pain in their lower belly. As the tumor grows, it can press on other parts. It can also spread to the liver or lungs.

Age is a big factor for this sickness. Most women find out they have it after menopause. This is the time when a woman's monthly cycles stop. Some women have a higher risk because of their genes. Changes in genes called BRCA1 or BRCA2 can lead to cancer.

Doctors can use surgery or medicine to help treat it.

Ovarian cancer is a serious sickness caused by a tumor in an ovary.

This tumor can start inside the ovary itself. It can also start in nearby parts like the fallopian tubes. It may even begin in the inner lining of the abdomen. The ovary is made of three different kinds of cells. These include epithelial cells, germ cells, and stromal cells. When these cells become abnormal, they divide too much. This causes a tumor to form. These cells can also spread to other parts of the body.

Finding this sickness can be a hard job. Early on, there may be no symptoms at all. Some women only feel vague changes in their bodies. As the cancer grows, symptoms become easier to notice. A person might feel bloated or have a swollen belly. Other signs include pelvic pain, constipation, or a loss of appetite. The cancer can spread to the lungs or the liver. It can also move to the lymph nodes or the abdominal lining.

Scientists and doctors have studied many ways this happens. They know that age is a major factor for risk. Most cases happen after menopause, which is when monthly cycles stop. Women who have ovulated more often may have a higher risk. This includes women who never had children. It also includes those who started ovulation at a young age. Some people also have a higher risk because of their genes.

There are many important facts about this disease. About 10% of cases come from inherited genetic risks. People with mutations in the BRCA1 or BRCA2 genes have a high risk. For example, BRCA1 mutations can lead to a 15% to 45% lifetime risk. In 2020, about 313,000 new cases occurred globally. In the United States, the five-year survival rate is 52%. In 2019, there were 13,445 deaths from this cancer in the U.S.

Understanding these facts helps people stay healthy. Knowing about risk factors like obesity or hormone therapy is helpful. Some things, like breastfeeding or pregnancy, can actually lower the risk. Doctors can use surgery, radiation, or chemotherapy to treat the disease. If it is caught in an early stage, it is often curable. This is why learning about the signs is so important.

Ovarian cancer is a serious disease caused by the growth of cancerous tumors.

These tumors can originate within the ovary itself. They may also begin in nearby structures, such as the fallopian tubes or the inner lining of the abdomen. The ovary is composed of three specific cell types: epithelial cells, germ cells, and stromal cells. When these cells become abnormal, they begin to divide uncontrollably. This process creates a tumor that can eventually invade or spread to other parts of the body.

The mechanism of the disease often involves the spread of cells, known as metastases. Cancer cells can travel to the lining of the abdomen, lymph nodes, lungs, or the liver. Because the ovaries are located deep in the pelvis, tumors are often quite large by the time they are found. As a mass grows, it may press on other organs in the abdominopelvic area. This pressure can cause significant pain or even ovarian torsion, where the ovary twists. In advanced stages, fluid can accumulate in the abdomen, a condition called ascites.

There are several distinct types of ovarian cancer based on the cells involved. Epithelial ovarian carcinoma is the most common, making up more than 95% of all cases. Within this category, there are five main subtypes. High-grade serous carcinoma (HGSC) is the most frequent subtype of epithelial cancer. Other, less common types include germ cell tumors and sex cord-stromal tumors. In children and adolescents, sex cord-stromal tumors can actually produce hormones. This might lead to the premature development of secondary sex characteristics.

Scientists have identified many risk factors that influence the likelihood of developing this cancer. Age is a major factor, as most cases occur after menopause. Risk is also linked to the number of times a woman has ovulated during her life. For example, women who began ovulation at a young age or reached menopause later face higher risks. Conversely, factors like pregnancy and breastfeeding can decrease risk. This is because ovulation is suppressed during these times. Other risks include obesity, diabetes mellitus, and the use of hormone replacement therapy.

Genetics play a critical role in about 10% of all cases. The most significant genetic risk comes from mutations in the BRCA1 or BRCA2 genes. These mutations can be inherited from either the mother or the father. A woman with a BRCA1 mutation has a lifetime risk of 15% to 45%. A woman with a BRCA2 mutation has a lifetime risk between 10% and 40%. Certain family syndromes, such as Lynch syndrome, also increase the risk. For those with these inherited mutations, cancer often develops about 15 years earlier than in other cases.

The impact of ovarian cancer is significant in terms of global health statistics. In 2020, approximately 313,000 new cases were reported. In the United States, it is the second-most common gynecologic cancer. It also causes more deaths than any other cancer of the female reproductive system. In 2019, there were 13,445 deaths from this disease in the U.S. alone. Globally, deaths from ovarian cancer increased by 84.2% between 1990 and 2017. The overall five-year survival rate in the United States is currently 52%.

Understanding these connections helps doctors develop better treatment and prevention strategies. A diagnosis is usually confirmed through a biopsy, where tissue is removed during surgery. If the cancer is caught in an early stage, it is often curable. Common treatments include a combination of surgery, radiation therapy, and chemotherapy. While screening is not recommended for women at average risk, those at very high risk may choose to have their ovaries removed preventively. Success in treatment often depends on the specific subtype and the extent of the disease.
