It’s not clear what causes ovarian cancer, though doctors have identified factors that can increase the risk of the disease.
In general, cancer begins when a cell develops errors (mutations) in its DNA. The mutations tell the cell to grow and multiply quickly, creating a mass (tumor) of abnormal cells. The abnormal cells continue living when healthy cells would die. They can invade nearby tissues and break off from an initial tumor to spread elsewhere in the body (metastasize).
Genes are responsible for some cases of ovarian cancer?
Defects in the BRCA1 or BRCA2 genes are responsible for some cases of ovarian cancer.
Birth control pills increase the risk of developing ovarian cancer?
Birth control pills decrease the risk of ovarian cancer. However, estrogen replacement therapy taken for a period of more than 5 years may increase the risk of developing the cancer.
Ovarian cancer is most common in women between the ages of 20 and 40 years?
Ovarian cancer is most common in women over the age of 55 years.
The CA-125 blood test is useful to evaluate response to treatment?
The CA-125 blood test is useful to evaluate response to treatment, especially if the initial levels are high.
The most common type of ovarian cancer is?
Epithelial tumor, which arises from the surface cells of the ovary, is the most common type of ovarian cancer.
The risk of ovarian cancer is higher in a woman who has close blood relatives suffering from the same cancer?
The risk of ovarian cancer is higher in a woman who has a first-degree relative suffering from the same cancer. The risk is even higher if a woman has one first-degree relative and one second-degree relative with the cancer.
Radiotherapy is the preferred mode of treatment in most cases?
Surgery and chemotherapy are preferred over radiotherapy in most cases of ovarian cancer.
Pap smear is used to diagnose ovarian cancer?
Pap smear is used to diagnose cancer of the cervix, that is, the lower part of the uterus.
In women at a very high risk of developing ovarian cancer, the ovaries may be surgically removed before the development of the cancer?
In women at a very high risk of developing ovarian cancer, the ovaries may be surgically removed before the development of the cancer in order to prevent the cancer.
Symptoms of ovarian cancer are usually noticed in the early stages of the disease?
In most cases of ovarian cancer, the symptoms appear only in the late stages of the disease. These symptoms are usually not specific for ovarian cancer, therefore resulting in a delay in the diagnosis and treatment.
