Aclient with ovarian cancer asks the nurse, "what is the cause of this cancer? " which is the most accurate response by the nurse?

In its earliest stage, the disease is largely asymptomatic. The causes of the disease is still unknown, but like other types of cancer, the risk of developing ovarian cancer is related to environmental, endocrine, and genetic factors. Also the use of oral contraceptive increases the risk of acquiring the disease. By the factors listed above we mean a family history of ovarian cancer, a long history of endometriosis, the use of certain fertility drugs or hormone therapies, and genetic mutations of genes
