Ovarian cancer makes up 4% of the malignant diseases in women. Research shows that occurrence of ovarian cancer is more common in the developed countries (as opposed to the nondeveloped countries), and that the risk of getting it increases with woman's age. It has been proven that main problem of the diagnosis is the late detection, specifically pathogenesis, and the fact that not all the risk factors for developing the illness are known. Female genital organs are formed in a way that allows conceiving, developing the embryo and giving birth to a baby. Just as other organs, ovaries too are extremly important in a female reproductive system which is why the health care has been increasingly interested in trying to find the ways of discovering the cancer sooner and preventing it. The initial symptoms include light pain, stomach discomfort, feeling bloated and feeling full. While those should act as the red light for visiting s gynecologist. Most woman unfortunately ignore the symptoms and think of them as belonging to another, temporary illness. Malignoms are the most common in woman between the ages 40 and 60, and one can differentiate between plenty tumor groups, such as epithel tumors, germ cell tumors, sex cord-stromal tumors and metastatic tumors. As with every disease, there are risk factors that can increase or decrease the probability of developing ovarian cancer. Giving birth, nursing and oral contraceptives decrease the probability of getting cancer (compared to those woman who are infertile and don't use fertility drugs). A nurse is an extremely important factor during the process of diagnosing and treating oncological patients. She is a highly competent and moral person with high level of emathy for the patient and his family as she is the one who spends the most time with patient during the entire process. She inculdes the patient in all the therapeutic procedures, educates him or her on the health care and spots new symptoms emerging or the existing symptoms worsening. Also, the nurse is available to the whole family and answer their questions as cancer is not an illness that affects only one person, but also all of those who surround him or her.
