Ovarian Cancer is similar to...?

What type of cancer is Ovarian Cancer similar to in nature? I know each is different, but is the cancer itself similar in nature/structure to breast cancer, etc?

The most common ovarian cancer is carcinoma which is in general from the epithelial lining component of the ovary. In addition, there are germ cell and sex cord type cancer in the ovary as well.
Carcinoma can be in many organs such as lung, breast and gastrointestinal tracts. Some cancers tend to spread via lymphatic drainage, some via blood stream and some locally. The ovarian carcinoma likes to spread to the omentum as well as surrounding fallopian tube, uterus and sometimes cervix.
The prognosis depends on the stage or the extent of the cancer at the time of the diagnosis (size, spread, differentiation or grade, etc.).
In general the ovarian cancer prognosis appears to be worse than many other cancers. The main reason is ovarian cancer is often diagnosed at a later stage than other cancers. Other cancers may either show earlier symptoms or signs. There is no effective screening for ovarian cancer unlike others such as cervical and breast cancer (by pap smear and mammogram respectively).
Good luck.

I don't think ovarian cancer is similar to any other--my mom had it for 3 years, and it just kept spreading from place to place--spleen, brain, etc. You can live from this type of cancer if you catch it in the early stages--but if you catch it in the late stages--it is not good!
